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 →

For those that are interested in the basics of parasitic resistance and a quick overview of how to manage parasites on-farm, view the video below. This is a great resource for all producers raising grazing livestock.

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 →

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 →
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 →
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 →
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 →

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.
