Caseous Lymphadenitis (CL) in Sheep and Goats

Dr. Maria Leite-Browning, DVM, Extension Animal Scientist, Alabama A&M University
(Previously published as a Fact Sheet with the Alabama Cooperative Extension System)

Introduction
Caseous Lymphadenitis (CL) is a chronically infectious disease of sheep and goats that is caused by the bacterium Corynebacterium pseudotuberculosis. Prevalent on all continents throughout the world, CL causes ulcerative lymphadenitis in horses and superficial abscesses in bovines, swine, rabbits, deer, laboratory animals, and humans. This zoonotic disease (a disease transmitted from animals to humans) is usually underestimated because CL is not a reportable disease in many countries, including the United States.

Some economic losses due to CL are Continue reading

One of the outcomes of having a high lambing/kidding percentage (greater than 200%) is that you may end up with some lambs/kids that you have to raise artificially. While some ewes/does will be able to raise triplets (even quads), sometimes it may be necessary (or wise) to remove lambs/kids from large litters in order to obtain more satisfactory weight gains.

There are different opinions as to which offspring should be removed for artificial rearing. Traditionally, it was recommended that Continue reading

Foot Rot and Scald

Michael Metzger, Michigan State University Extension Educator
(Previously published on MSU Extension, Sheep & Goat: December 21, 2018)

Foot rot and foot scald in goats and sheep.

Foot rot and foot scald are contagious diseases of the hooves in goats and sheep.

According to Michigan State University Extension Educator Mike Metzger, a cool wet fall can increase foot scald and foot rot in small ruminants. Foot scald and foot rot are costly diseases in the sheep and goat industries. Producers lose significant time and money every year attempting to control it in their flock or herd. If foot rot and/or foot scald becomes a problem on your farm it takes a lot effort and labor to control symptoms and eliminate it. However these conditions are preventable with good management.

Keeping Newborn Lambs Fed and Warm

Jeff Held, South Dakota State University Sheep Extension Specialist
(Previously published on iGrow, a service of SDSU Extension)

Newborn Lamb Care Management.

Proper newborn lamb care is a critical component of flock profitability. In the U.S., lamb mortality from all causes is approximately 20% with more than 80% of those losses occurring in the first two-weeks following lambing. Yet a solid lamb care management plan coupled with a few key tools in the lambing barn can sharply improve the number of lambs reared per-ewe. Generally, the top causes for newborn lamb losses are starvation, hypothermia (cold stress), respiratory disease, and scours followed by injury. Theoretically, these categories each stand alone, however the reality is often two-or-three of these occur simultaneously. Producers that develop a lambing time-management plan to incorporate appropriate lambing tools and gain key skills on newborn lamb care will benefit from less labor input and expense with a greater number of lambs weaned.

Colostrum is the key to raising healthy goat kids and lambs.

Ensuring goat kids and lambs get enough colostrum at birth is imperative to getting them off to a good start.

One of the most important functions of colostrum (first milk) is to provide kids and lambs with antibodies (immunoglobulins) that provide passive immunity for the first two months of life. Newborn lambs and kids, like other mammals, are born with no antibodies of their own and rely on those provided by the mother in colostrum for protection.

Protection provided by Continue reading

Listeriosis Control and Prevention

Michael Metzger, Michigan State University Extension Educator
(Previously published on MSU Extension, Sheep & Goat: November 28,2018)

Listeriosis is a disease that can affect all ruminants, as well as other animal species and humans.

Listeriosis is an important infectious disease of sheep and goats. It most commonly causes encephalitis but is also capable of causing blood infections and abortion.

Listeriosis is caused by the bacterium Listeria monocytogenes and is commonly seen in cooler climates. These bacteria can be found in the soil, food sources and even the feces of healthy animals. Most commonly, this disease of sheep and goats is observed as a result of feeding moldy or spoiled hay or silage. It’s possible for sheep and goats to become infected without feeding moldy or spoiled hay or silage, as it is also found in the environment. The bacteria are very hardy and are common in soil.

Possible locations of Listeria monocytogenes bacteria: Continue reading

Pregnancy Toxemia (a.k.a. Ketosis)

Susan Kerr, WSU NW Regional Livestock and Dairy Extension Specialist
(Previously published on Oregon State University Small Farms page)

Pregnancy Ketosis

New producers of small ruminants often learn about pregnancy ketosis first time the hard way—with a dead dam, fetuses or both. This article explains the causes of pregnancy ketosis (a.k.a. toxemia) and more importantly—how to prevent it.

This ewe had milk fever, but advanced pregnancy ketosis would present similarly: a down and depressed animal with poor appetite. Lack of complete recovery after calcium treatment and results of ketone tests would help differentiate these two conditions. Also, milk fever usually occurs after lambing and pregnancy ketosis before. Photo courtesy Susan Schoenian, University of Maryland Extension.

Sheep and goat fetuses add 70% of their final birth weight in the last six to eight weeks of gestation. A singleton increases a dam’s nutritional requirements by 1.5 to 2 times maintenance in the last trimester. Multiple fetuses greatly increase energy demands on their mother: twins require 1.75 to 2.5 times maintenance requirements and triplets demand up to 3 times maintenance. Twins and triplets are common in some breeds of sheep and goats; quadruplets and even more are not uncommon in Boer goats, Finnsheep and Romanov sheep. Continue reading

Infectious Causes of Abortion in Ewes

Susan Schoenian, Sheep & Goat Specialist, University of Maryland Small Ruminant Extension Program
(Previously published on the Maryland Small Ruminant Page)

There are many things than can disrupt a healthy pregnancy in a ewe. While it is common for about 25% of embryos to die or be reabsorbed the first three weeks of pregnancy up to the time of implantation, these are the most crucial in establishing healthy pregnancies. The nutritional requirements of ewes during early gestation is only slightly more than maintenance requirements, but it is essential that the flock not be exposed to any undue stresses.

It appears normal for about 1.5 to 2.0% (up to 5%) of the ewes in a flock to abort. Abortion rates significantly above this level cut into profit potentials, as what may start out as a few isolated cases can quickly escalate into an abortion “storm,” resulting in 20-30% percent abortions or as high as 80% lamb mortality.

Preparing for Winter

Michael Metzger, Michigan State University Extension Educator
(Previously Published on the Michigan State University Extension page: November 15, 2017)

Preparing goats and sheep for winter weather.

Most goats and sheep spend most of their time outside, but livestock that live outside may need special care when the winter weather sets in.

All animals need some kind of shelter even if it is only a windbreak. They need a place where they can get out of the wind. Shelter can include a building, a three-sided shed or even just a tree line. Ideally, goats and sheep should have access to some type of free choice shelter with a roof so they can get in out of the rain and snow. Continue reading

With lambing season right around the corner, shepherds need to start preparing now. In this weeks Ag-note, OSU students Kelvin Moore, Sade Payne, and Elizabeth Spahr highlight the importance of a sound vaccination program using the CDT vaccine.

The CDT vaccine is yet another management tool found in the shepherd’s toolbox that is used to protect small ruminants against clostridium perfringens types C and D as well as clostridium tetani (tetanus). Appropriate use of this vaccine is a safe, cheap, and an effective method used to control for clostridial diseases in your flock. Continue reading

Rabies in Livestock

Dr. Tim McDermott, OSU Extension Educator ANR, Franklin County
(Previously Published in Farm and Dairy: November 15, 2018)

Many diseases can affect animals on pasture. The most difficult ones to stay aware of are the diseases that are uncommon, where the producer or livestock may never encounter the disease. Many diseases that affect livestock have presentation forms that can mimic multiple other diseases that are more common, leading to a delay in veterinary care or producer awareness. One disease that can affect livestock that fits this description, but should stay firmly in a producer’s awareness is rabies.

Rabies is an ancient disease caused by a virus. The Latin translation of rabies means, “To rave or rage”. The virus spreads in its host in an unusual way compared to how most people think of viral spread. While many viruses spread through the bloodstream, enter via the respiratory tract or digestive tract by ingestion, rabies is a neurotropic virus, meaning it spread along the nerves in the nervous system. After an infected host bites Continue reading

Winter Ewe Management Tips

Beware of Frost-damaged Forages

Sandy Smith, OSU Extension Educator ANR, Carroll County
(Previously published in Farm and Dairy: October 25, 2018)

Last week, we experienced our first frosts of the season in some areas of Ohio, but I don’t think anyone has experienced the real killing frost yet.

When some forages freeze, changes in their metabolism and composition can be toxic to ruminant livestock. The two problems that can occur are prussic acid (hydrogen cyanide) poisoning and bloat.

Beware of poison

First, I want to write about prussic acid or cyanide poisoning. Sorghum-related plants such as grain sorghum, sorghum-Sudan grass and Sudan grass varieties can contain toxic levels of cyanide after a frost. Johnsongrass, black cherry and elderberry can also develop toxic levels of prussic acid after a killing frost.

Light frost can stress plants, but do not kill them entirely can also cause cyanide poisoning. Continue reading

Risks of Nitrate Poisoning in Pastures

Mark Johns and Barry Yaremcio, Ag – Info Centre, Alberta Agriculture & Rural Development
(Previously published on Alberta.ca – Agriculture and Forestry: February 26, 2018)

This past weekend I had a question from a sheep producer asking why he was loosing several ewes unexpectedly. Further into the conversation, he also mentioned that he figures on losing a dozen ewes during this time (fall) each year. My response to this was “has there been any instances of frost over the course of time that you have been loosing ewes and what types of forages are in your pastures?” Of course without visually seeing these animals and not having any lab work or even a field necropsy performed, it is hard to say what the exact cause of each case may have been. However, as we begin to move into colder temperatures with periods of frost and with producers potentially spreading manure prior to the winter months, it is important consider how these scenarios can affect plant species in your pastures. With this being said, the scenario listed above could have been the result of nitrate poisoning. To learn more about this issue with grazing livestock, check out this Q&A session provided by Mark Johns and Barry Yatemcio.

Stiff lamb disease – nutritional muscular dystrophy.

What is it?
White muscle disease (WMD) is a degenerative muscle disease found in all large animals. WMD is caused by a deficiency of selenium and/or vitamin E. Generally, it is not known which. Selenium (Se) deficiency is associated with selenium deficient soils and the inadequate uptake of selenium by forages grown on these soils. Certain areas of the U.S., including the Northeast, are considered low in selenium levels. Selenium deficiency occurs when the soil contains less than 0.5 mg Se/kg of soil and locally harvested feeds contain less than 0.1 mg Se/kg of feed. Continue reading

Chronic Copper Poisoning in Sheep

Dr. S. John Martin, Veterinary Scientist, Sheep, Goat, and Swine
(Previously published on the Ontario Ministry of Agriculture, Food, and Rural Affairs web page)

How does chronic copper poisoning (CCP) occur?
Sheep are the domestic animal most prone to CCP. They absorb copper from the diet in proportion to the amount of copper offered, not to the body’s need as with the absorption of other minerals. Any excess absorbed copper is stored in the cells of the liver, eventually reaching toxic levels. Levels in the liver above 500 ppm dry weight are usually considered toxic. This storage in the liver can take months or even years to reach a toxic level. The elimination of copper from the body through the kidneys is slow.

Even then, it needs a stress to release the copper. This stress can be weather, poor nutrition, transportation or handling. The liver cells rupture, releasing copper into the blood stream. There are suggestions that excess liver copper can Continue reading

Understanding how to prevent and treat Polioencephalomalacia (PEM) in sheep and goats.

Polioencephalomalacia (PEM) is also known as cerebrocortical necrosis (CCN) and is a relatively common nutritional disorder in sheep and goats. A common name for this disease in sheep and goats is “polio”; however, it has absolutely no relationship with the infectious viral disease found in humans (poliomyelitis). Cases of PEM can be successfully treated if detected early in the disease course, making recognition of early symptoms a critical issue for sheep and goat producers.

Causes of PEM
The most common cause of PEM is Continue reading

An Alternative Use for Wool

(Previously published in Feedstuffs, Nutrition and Health: August 17, 2018)

Wool may offer dietary protein source.

Wool protein hydrolysates offer promise as functional ingredient in pet foods as well as other foods and feeds.

Developing new products from available resources often requires scientists to think differently, and such new products can offer new revenue streams for animal agriculture sectors.

Researchers with New Zealand’s AgResearch have discovered that proteins from wool can be added to the diets of animals to improve their health, opening up a new market for the sheep industry. Continue reading

A Brief Refresher on Sheep Diseases

Susan Schoenian, Sheep & Goat Specialist, University of Maryland Small Ruminant Extension Program
(Previously published on the Maryland Small Ruminant Page)

(Image Source: Susan Schoenian, Maryland Small Ruminant Page)

Some diseases that affect sheep.

Sheep can be affected by many diseases. This article gives an overview of some of the most common diseases of sheep. Scrapie, though uncommon, is also included, because it is important for reasons of public health and perception.

Abortion
Abortion is when pregnancy is terminated and the ewe loses her lamb(s), or she gives birth to weak or deformed lamb(s) that die shortly after birth. While it is not unusual for some ewes to abort, flock abortion rates in excess of 5% are usually considered problematic.

There can be many reasons for abortion, and it is not always easy to determine the cause. In the US, the most common infectious causes of sheep abortion are Continue reading

Pneumonia in Sheep and Goats

Dave Van Metre, DVM, DACVIM Professor / Extension Veterinarian, Colorado State University

Pneumonia is an infection of the lung tissue with multiple causes. It is an important medical problem of sheep and goats of all ages. In younger animals, various bacteria, viruses, and parasites of the upper and lower respiratory tract are often involved in the development of pneumonia. In adults, these same diseases – causing agents can create pneumonia.

In sheep, a systemic virus known as Ovine Progressive Pneumonia Virus (OPPV) can play an important role.

In goats, a similar systemic virus, the Caprine Arthritis and Encephalitis Virus (CAEV), can cause pneumonia.

The word “systemic” means that OPPV and CAEV are viruses that can affect multiple organs, including the lungs. These viruses can also affect the brain, udder and the joints. In certain climates, parasites (worms) can travel from the gastrointestinal tract to the lungs, causing pneumonia.

What conditions increase the risk of pneumonia? Continue reading

P. tenuis, Meningeal Worm in Small Ruminants

Dr. Tim McDermott, OSU Extension Educator ANR, Franklin County
(Previously Published in Farm and Dairy: July 12, 2018)

When I was a veterinary student in the 1990’s in parasitology class we learned about Paralephostrongylus tenuis (P. tenuis), the meningeal worm primarily affecting small ruminants, as an uncommon, even rare occurrence in private practice.  When I joined Extension in 2015 in Hocking County, I found that for small ruminant producers in southeastern Ohio, this parasite was frequently encountered.  P. tenuis is a type of roundworm that has white tailed deer as its primary host.  In white tailed deer however, the parasite infrequently causes illness, but instead will live inside the deer for years with no outward medical signs, excepting only eggs shed from the roundworm into the environment within the deer feces.  The life cycle of this roundworm parasite is classified as indirect.  This means that further maturation of the parasite into an infective larval stage occurs in a second host outside of the deer and this intermediate host is then ingested by another species.  The intermediate host for P. tenuis is Continue reading

Mycotoxin Concerns when Feeding Small Ruminants

Identifying Corn Ear Rots (Image Source: No-Till Farmer)

Introduction
During the 2009 Indiana corn harvest, livestock producers heard numerous reports of mycotoxin levels high enough to cause concern. The main mycotoxins in feed grains that sheep and meat goat producers need to be concerned with are deoxynivalenol (DON) and zearalenone (ZEN). Deoxynivalenol is also known as vomitoxin. Zearalenone arises from Gibberrella ear rot, or Gib ear rot. Both of these mycotoxins are produced by a Fusarium fungus. There is a limited amount of research and extension information available on the effect of sheep performance when consuming feeds infected with DON and ZEN. There is less information for Continue reading

Tall Fescue Toxicosis – Knowing the Signs

Christine Gelley, OSU Extension Educator ANR, Noble County

Kentucky 31 tall fescue

Tall fescue “Kentucky-31” (KY-31) is one of the most predominant forages in the nation. Its popularity began in the 1930s when a wild strain of fescue was discovered on a Kentucky farm and it became recognized for wide adaptability. In the1940s, the cultivated variety was publically released and can now be found in most pastures in the United States. This cultivar is easy to establish, persistent, tolerant of many environmental stresses, resistant to pests, and can aid livestock managers in prolonging the grazing season. However, tall fescue does not accomplish all of these tasks unassisted.

An endophytic fungus called Neotyphodium coenophialum can be credited for many of these benefits. The fungus cannot be seen and can only be detected by laboratory analysis. The fescue endophyte forms a mutually beneficial relationship with the grass, but Continue reading

How to Battle Footrot

Dr. Bill Shulaw, OSU Extension Veterinarian

This week we dig back into our archives to find an article that many could probably related to, especially with the weather that we have been experiencing!

With an unusual wet spring and summer, this situation has opened up the door for a common sheep disease to drastically affect your flock: contagious footrot. Warm wet weather softens the hoof and soft tissues between the toes making the foot more susceptible to infection. It also favors the transmission of the causative bacteria, Dichelobacter nodosus (formerly Bacteroides nodsus), from the hooves of carrier sheep to the hooves of unaffected animals. For a review of the causes of virulent and benign footrot in sheep, as well as “scald,” the reader is referred to the appropriate section in the latest edition of the SID Sheep Production Handbook available through the American Sheep Industry.

When footrot appears in a flock, it often Continue reading

Why Ewe Should Control Feed Intake
** Follow the link above to view the Ag-note.

This weeks Ag-note comes from OSU students Carolina Fernandez, Dermot Hutchinson, Randi Shaw, Jake Parkinson, and Caitlyn McCaulley as they present a detailed overview on the importance of controlled feed intake in small ruminants. The students were inspired by Dr. Francis Fluharty to present on this topic as Dr. Fluharty expressed that this type of feeding strategy is not just limited to feedlot cattle. Although controlling feed intake comes with a cost due to an increase in labor and time spent feeding, the benefits from this strategy certainly outweigh these costs.

At a basic level, producers have two options when it comes to feeding strategies, Continue reading

On-farm Biosecurity

Rory Lewandowski, OSU Extension Educator ANR, Wayne County
(Previously published in: A Guide to Katahdin Hair Sheep)

As we begin yet another season filled with selling and showing livestock, it is important to keep biosecurity in mind. Rory reminds us that most economically important diseases are purchased. All newly purchased animals should be quarantined before introducing them to your flock. Therefore, as you consider purchasing a new stud ram or plan on taking your flock to the county fair, proper biosecurity measures will pay off for you and your flock in the long run.

How easy or difficult would it be to introduce an infectious disease into your flock? Do you know the factors that increase the risk of introducing an infectious disease into your flock? Farm biosecurity is about Continue reading

With Sheep, The Cheapest Mineral Isn’t

can be quite costly initially, Dr. Fluharty outlines the risks and production losses associated with the lack of mineral supplementation.

The major nutritional requirements are: water, energy, protein, minerals, and vitamins. In many cases, sheep producers do a good job of providing adequate water, energy, and protein. However, many sheep producers buy ‘cheap’ minerals, ignoring the fact that the availability of the minerals in the oxide form is low. In many of these mixes, only 10-20% are Continue reading

Management Tips:
Within 2 to 4 hours after birth, decide which lambs among those needing assistance should be removed from their mother. Look for the stressed, or small lambs to select for artificial rearing.
It is important that newborn lambs receive colostrum within the first four hours. The best source of colostrum is from the mother but other ewes within the flock provide a high level of immunity. Continue reading

Hypothermic Lambs: How to Defrost before They’re in the Freezer

Jackie Lee and Kathrine Yunker, 2019 College of Veterinary Medicine DVM Candidates, The Ohio State University
(previously published on Talking Sheep – Sheep Education and Information: February 19, 2018)

Although mother nature can not make up her mind when it comes to the weather, this piece of information still serves a great purpose as it reminds us about the issues that can arise as a result of hypothermia and hypoglycemia as well as the management practices that can be implemented in order to decrease the losses associated with both of these issues.

Winter has already been harsh this year, making it only fitting to write about hypothermia in lambs. Even with the best management, this is bound to be an issue for many sheep producers. Hypothermia has many causes and can affect lambs at different ages. In newborn lambs less than five hours old, hypothermia often occurs due to prolonged exposure to cold temperatures.

Difficult or premature births can Continue reading

Make sure your lambs are off to a good start by using “clip, dip, and strip” in your lambing practices. This simple technique, suggested by former Penn State University Extension Educator Michael Fournier, will aid in keeping newborn lambs healthy.

1 – Clip
Clip refers to trimming the umbilical cord. When a lamb is born, it will have an umbilical cord of varying length still attached to the belly, which can be an open highway for bacteria. If the umbilical cord is Continue reading

Livestock Water is Essential, Even in Winter

Ted Wiseman, OSU Extension Educator ANR, Perry County

(Image Source: Catskill Merino Sheep)

Water is essential for all livestock regardless of the time of year. So far this year we have certainly had our share of chopping ice, thawing water lines and troughs. With recent temperatures many of us often focus on keeping livestock well fed and with adequate shelter. However, often times we forget about the most important nutrient which is water. Water consumed by livestock is required for a variety of physiological functions. Some of these include proper digestion, nutrient transportation, enzymatic and chemical reactions, and regulation of body temperature.

Although water is the cheapest nutrient we may purchase or provide, it is the one we provide the most of on a per pound basis. For example, every pound of dry matter consumed, Continue reading

Protect Sheep and Goats with CDT Vaccine

Peggy Coffeen, Dairy/Livestock Editor

This week we have another achieved article resurfacing from just few years ago. In this article, Dr. Eric Gordon, a member of the OSU Sheep Team, outlines the importance of a proper vaccination program. Be sure to check out this quick piece to learn more about the benefits of vaccinating your herd or flock with CDT.

Failing to arm sheep and goats disease protection is a bit like heading into a tackle football game with no helmets or pads. Less protection means greater risk. Vaccines are an important component in suiting up small ruminants to hit the field – or pasture. At minimum, sheep and goats of all ages and stages should be protected from clostridial diseases.

Management Considerations to Lower Lamb Mortalities

Dr. Bill Shulaw, OSU Extension Veterinarian

Once again, we have dug back into the achieves to provide an article by Dr. Bill Shulaw that outlines management strategies that can be implemented in order to decrease lamb losses associated with improper management and disease control that may be prevalent during the first few weeks of life. Whether you have raised sheep for a year or 50 years, reviewing this article would benefit all shepherds as it outlines simple control and management strategies that can certainly benefit any operation.

There are many factors that affect lamb survival. Serious shepherds should consult the Sheep Production Handbook, produced by the American Sheep Industry Association (www.sheepusa.org), for a more complete discussion of the various conditions and infectious diseases which impact lamb survival. However, Continue reading

Do Sheep and Goats get Cold?

During this time of year, the hills of eastern Ohio are covered in snow, frozen waterfalls, and massive icicles. Most of us enjoy spending these cold winter days indoors next to the fireplace or with the furnace working overtime. So with their thick wool coats, are sheep actually keeping as warm as you think? What about goats that do not have those nice thick coats? Are they just used to the cold? During the winter, extreme temperatures, precipitation and wind can create Continue reading

Mastitis: An Issue Not to be Taken Lightly

Mastitis in Small Ruminants:

What is mastitis?
Mastitis in goats and sheep, similar to cows, is defined as inflammation of the mammary gland and can occurs due several factors, which may be infectious or not and may present in clinical or subclinical form. In clinical mastitis, it is possible to observe the signs of inflammation, such as: Continue reading

How can Delayed Weaning Benefit your Operation?

Brady Campbell, Program Coordinator, OSU Sheep Team

At what age do you wean your lambs? This is a question that I have asked producers many times. I have heard ages ranging from 35-130 days of age with the most common answer being 60 days of age. This is the most common weaning age for producers in the eastern United States. When I ask producers why they wean their lambs at 60 days of age or younger, most respond with “that’s the way we have always done it here on the farm, so why change now?”

From a researcher’s perspective, this is not a valid answer. Weaning before the natural weaning age (between 100-180 days of age depending upon sheep breed) is stressful. Weaning stress can lead to decreases in animal performance as demonstrated by decreased weight gain. Weaning stress can also result in decreased animal health as shown by decreases in immune system function that can lead to an increased susceptibility to disease and infection. However, if we were Continue reading

The Importance of Colostrum Management

Dr. Cassandra Plummer, DVM, Small Ruminant Veterinarian, Iowa State University College of Veterinary Medicine

This week we have another article pulled from the archives. Although its original publication date was nearly 10 years ago, this piece does a great job outlining the importance of colostrum. For those that are nearing lambing, be sure to update yourself on the appropriate handling methods regarding the use of donor animal and frozen colostrum.

As we find breeding season winding to a close it is time to start making preparations for lambing season to begin. When preparing for lambing, one thing to consider is your plan for colostrum management. How are you going to get colostrum into your lambs? What if a ewe doesn’t have colostrum? How will you handle orphan lambs or bottle lambs? All of these things need to be considered prior to the start of lambing.

To start out with, what is colostrum? Colostrum is defined as Continue reading

Managing Starvation/Hypothermia

Dr. Bill Shulaw, OSU Extension Veterinarian

This piece from Dr. Shulaw was previously posted on the web page about 8 years ago. However, it contains a lot of valuable information as many producers here in the state of Ohio transition into the winter lambing season. Check out this article to refresh yourself on the dangers of the starvation/hypothermia complex. Understanding this complex will help you as a producer better prepare yourself for potential issues during this lambing season.

The starvation/hypothermia complex usually comes about when multiple contributing factors are present and not just the simple occurrence of cold weather. Some of these include failure of the ewe to care for the lamb, difficult birth resulting in a weak lamb, bacterial mastitis in the ewe, “hard bag” in the ewe caused by ovine progressive pneumonia (OPP) virus, and several infectious causes of abortions which also may result in live, but weak, lambs. Most producers will be confronted with the occasional hypothermic lamb. Continue reading

Shearing the Flock: When are you Shearing?

North Dakota State University
(Published in The Shepherd’s Guide – Supplement to The Shepherd Magazine)

Shearing sheep prior to lambing improves flock productivity. Shepherds have some simple ways to capitalize on one of the best lamb and wool markets the American sheep industry has seen. One of them is shearing sheep. It can have tremendous impacts on flock productivity, according to Reid Redden, North Dakota State University Extension Service sheep specialist. He recommends sheep producers have their sheep shorn 30 to 45 days before anticipated lambing for several reasons, including: Continue reading

Dangers of Harvesting and Grazing Certain Forages Following a Frost

Dr. Mark Sulc, OSU Extension Forage Specialist, The Ohio State University

As cold weather approaches, livestock owners who feed forages need to keep in mind certain dangers of feeding forages after frost events. Several forage species can be extremely toxic soon after a frost because they contain compounds called cyanogenic glucosides that are converted quickly to prussic acid (i.e. hydrogen cyanide) in freeze-damaged plant tissues. Some legumes species have an increased risk of causing bloat when grazed after a frost. In this article I discuss each of these risks and precautions we can take to avoid them. Continue reading

No More Free Plastic Scrapie Tags

Susan Schoenian, University of Maryland Extension, Sheep and Goat Specialist

As part of efforts to eradicate scrapie, US sheep and goat producers are required to follow federal and state regulations for officially identifying their sheep and goats. Prior to October 1, 2017, the National Scrapie Eradication Program provided free plastic ear tags and applicators. As of October 1, the program will only provide free metal tags. Continue reading

EHD Virus Confirmed in Ohio Deer and Cattle

Ohio Department of Agriculture (News Release from 8-22-17)

The first confirmed case of epizootic hemorrhagic disease (EHD) was recently confirmed in both white-tailed deer and cattle in Ohio. The virus was diagnosed by the Ohio Department of Agriculture’s (ODA) Animal Disease Diagnostic Laboratory (ADDL).

The positive diagnoses were from a cow from Jefferson County and a wild white-tailed deer buck from Lorain County. The discovery is not unusual, Continue reading

The Importance of Colostrum Management

Dr. Cassandra Plummer, DVM, Small Ruminant Veterinarian, Iowa State University College of Veterinary Medicine

As we find breeding season winding to a close it is time to start making preparations for lambing season to begin. When preparing for lambing, one thing to consider is your plan for colostrum management. How are you going to get colostrum into your lambs? What if a ewe doesn’t have colostrum? How will you handle orphan lambs or bottle lambs? All of these things need Continue reading

Protect Sheep and Goats with CDT Vaccine

Peggy Coffeen, Dairy/Livestock Editor

Failing to arm sheep and goats disease protection is a bit like heading into a tackle football game with no helmets or pads. Less protection means greater risk. Vaccines are an important component in suiting up small ruminants to hit the field – or pasture. At minimum, sheep and goats of all ages and stages should be protected from clostridial diseases.

Dr. Eric Gordon, DVM, The Ohio State University, believes that clostridial diseases are Continue reading

Fall Grazing Management and Plant Health

Rory Lewandowski, OSU Extension Educator ANR, Wayne County

Grazing management during the months of September and October directly impacts the vigor and growth of pasture in the spring. For the perennial grass plant, the fall season is a time of laying the foundation for next year’s growth. Although seed production is one way that a perennial plant can survive from year to year, in pastures the more important way that plants survive is through re-growth from buds located at the crown of the plant. It is during the short day, long night periods in the fall of the year that flower buds are formed/initiated on the crown of the plant. The plant leaf Continue reading

Footrot: Coming Soon to a Flock Near You

Dr. Bill Shulaw, OSU Extension Veterinarian

Green grass is beginning to peek through the brown plant residues on many Ohio pastures. If our weather pattern is typical this spring, we will soon be enjoying warmer, but wetter, weather. Although we will welcome the flush of new forage that this weather will bring, this is the major transmission season for one of the most common of sheep diseases: contagious footrot. Warm wet weather softens the hoof and soft tissues between the toes making the foot more susceptible to infection. It also favors the transmission of Continue reading

Diagnostic Sample Submissions for Animals

Dr. Bill Shulaw, OSU Extension Veterinarian

Lambing, kidding, and calving seasons are well underway and the typical questions about abortions, calf scours, and other problems have been asked. This week I was asked if I would provide some general guidelines about obtaining help with disease diagnosis.

First of all, getting at least a tentative diagnosis is crucial to formulating appropriate and cost-effective treatment, control, or prevention plans. Sometimes this isn’t easy or simple, but it should start with your local veterinarian. Most veterinarians can provide at least some diagnostic services that might Continue reading

Poisonous Trees

Clif Little, OSU Extension Educator, Guernsey and Noble Counties

Recent storms downed many trees throughout Ohio and some of these pose a threat to livestock. Poisoning is most common when grazing is scarce, such as periods of dry weather coupled with thunderstorms that down trees during the mid to late summer months.

Listed below are some of the most common poisonous trees found in Ohio pastures. Continue reading

Use FAMACHA Correctly for Best Results

Rory Lewandowski, OSU Extension Educator ANR, Wayne County

An important component of summer management is internal parasite control.  By this point in the calendar year sheep, and/or goats on many farms have rotated through pasture paddocks at least a couple of times. Lactating ewes and does can shed large numbers of parasite eggs, effectively seeding pasture paddocks with parasite larvae that are waiting to be ingested with the next grazing pass.  As young lambs and kids learn to graze at the side of their mothers, they are very susceptible to acquiring large parasite infections. However, parasite loads are not equally distributed within the herd or flock.

Over the past several years targeted selective de-worming treatment of sheep and goats has been promoted as one way to avoid treating the entire flock or herd. Selective treatment can slow down the process of the parasite acquiring chemical resistance and thereby prolong the effectiveness of those chemical de-wormers available to sheep and goat owners. One tool that is being used to determine selective treatment is the FAMACHA system. Continue reading

Common Poisonous Plants

Roger High, OSU Ohio State Sheep Extension Specialist

While most plants are beneficial, some are hazardous to animal and human life. Ohio has about 100 toxic plants and some of these are responsible for deaths of domestic livestock every year. The number of cases of toxicosis (plant poisoning) in livestock far outweighs those reported for humans. Accurate statistics are not available, but it is estimated that several thousand animals die annually in the U.S. from plant toxicosis.

With houses springing up everywhere in Ohio, the rural/urban interface is dramatically increasing. Many farm neighbors are unfamiliar Continue reading

Management Considerations to Lower Lamb Mortalities

Dr. Bill Shulaw, OSU Extension Veterinarian

There are many factors that affect lamb survival. Serious shepherds should consult the Sheep Production Handbook, produced by the American Sheep Industry Association (www.sheepusa.org), for a more complete discussion of the various conditions and infectious diseases which impact lamb survival. However, if a pregnancy is carried to term, most losses occur Continue reading

Nor-98 Like Scrapie Found in the United States

Becky Talley, Sheep Industry News Associate Editor

In February of last year, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) officially announced the discovery of a Nor98-like scrapie case in a ewe from a flock in Wyoming. This was the first case of scrapie consistent with Nor98 discovered in the United States.

Since then, four more cases have been discovered that originated from flocks in Colorado, Indiana, Minnesota and California. These cases are not related to either the first one in Wyoming or to each other.

This scrapie type was first found in Norway in 1998 Continue reading
