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 →
Regardless of the animals stage of production or time of year, Dr. Fluharty reminds us that mineral supplementation is important! Although mineral

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 →
Cattle, horses, sheep, and goats are all susceptible to internal parasites, which can be devastating to producers economically.
“Many times, the effects are subclinical and may go unnoticed, but severe infestations can cause disease and death,” says Adam Speir, a county extension agent with the University of Georgia’s forage extension team.
Speir notes that the effects of infestations can come in many forms, with the most common being reduced milk production, reduced weaning weights, delayed puberty, lower Continue reading →

Rearing Lambs Artificially
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 →
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.
Eight things to remember about soil and livestock health and improvement.
I don’t know about ya’ll but I spend a right smart amount of time planning to do better. I am so well organized that it is often a relief when my flip phone rings so I can find it.
One thing we need to do in the winter is rest up a little and think and plan and visit with other successful grazing beef producers. Most of us could use and profit from soil that is actually growing in organic matter, mineralization, color and depth. 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 →

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 →
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.

A few weeks ago I had the opportunity to attend the American Forage and Grassland Council Annual Conference with some of our other Ohio Extension Educators. It was a wonderful experience to learn from others and share what we have learned with forage producers and professionals across the country.
Two sessions that I sat in on for the benefit of my local producers were “Managing Clovers in the 21st Century” and “Understanding and Mitigating Fescue Toxicosis.” Continue reading →
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 →

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 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 →
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 →

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.
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 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 →

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 →

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 →

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 →
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 →
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 →

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 →
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 →

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 →

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.
