So, you’ve decided that sheep might be a nice addition to your existing farm, or a good place to start your farming adventures. You may have decided that Katahdins would be the best breed for your situation. After all, they’re hardy, easy care with their shedding hair coat and parasite resistance, and they’re wonderful mothers. Everything sounds great so far, but what now? Where do you go from here? And how do you actually get started? Part 1 of this two-part series will offer questions for you to consider on lots of important topics with links to other EAPK blogs…

Two Brothers: A Journey Through Changing EBVs

Let’s go on a journey with two Katahdin full sibling ram lambs and follow them as their EBVs change when their own performance is measured. Along the way I will do my best to explain why their EBVs changed at every step in the journey. We all know EBVs change, especially when you measure traits; hopefully looking at a case study helps you understand a bit better how and when EBVs can change. The data and dates used are real and the EBVs are real as returned by NSIP/LambPlan. The names have been changed to protect the innocent. We start…

Selecting the Optimal Sheep for Solar Grazing

While this article focuses on solar grazing, the principles discussed are relevant to all low-input, grass-based production systems. This article was originally published in the August 2025 issue of the Sheep Industry News and is reposted with permission. The rise of agrivoltaics—where solar energy production coexists with agricultural practices—has created new opportunities for sheep producers across the United States. As solar developers seek sustainable vegetation management solutions, sheep have emerged as an ideal partner, offering cost-effective and environmentally favorable grazing services. However, success in this dual-purpose system depends on more than just turning sheep loose under panels.A balanced approach to…

Evaluating Breeding Animals

Unfortunately, defects show up in some of our animals and even though those animals might be exceptional in other areas, for the betterment of the breed we should not propagate these defects. Always check your animals before keeping them as replacements or selling them as breeding stock. Bite In lambs the bottom teeth should “bite” into the dental pad. They should not extend in front of it (monkey mouth, undershot), nor be too far backwards (parrot mouth, overshot). If a bite is VERY off you can easily see that the bottom jaw is markedly longer or shorter than normal at…

Ram selection and breeding decisions have lasting impacts on your flock. When replacement females are retained, these decisions can quickly account for a significant majority of your genetics. Just because a ram is a crowd favorite at a sale or a leader in a particular trait or two does not mean it is the right ram for your operation at that given time. The following steps should be taken to carefully evaluate your flock and make accurate ram selection decisions. Establish Goals: The first step to finding the right ram is determining goals for your flock. These goals should take…

Sheep GEMS News Brief 12 – March 2025 In the last Sheep GEMS news brief, we talked about the impact of parasites on production, and it was eluded that genetic selection can be a very promising means to manage worm parasites. Continuing with the Sheep GEMS theme of breeding for climatic resilience and robustness across environments, parasite resistant sheep express improved fitness. Determining fecal egg counts (FEC) at the time of weaning and post-weaning is a measure of parasite resistance already included in the National Sheep Improvement Program (NSIP). Collaboration with the GEMS innovation flocks and 3 USDA ARS facilities…

Sheep GEMS News Brief 11 – Late February 2025 Gastrointestinal parasites are one of the main health concerns for grazing sheep because available dewormers are largely ineffective due to dewormer resistance. Parasitic worms are a year-round problem in tropical and sub-tropical environments affecting millions of small ruminants world-wide. However, resistance to multiple deworming drugs is common in small ruminants. Infection with gastrointestinal nematode parasites can cause reduced weight gains, fertility, fiber and milk production, as well as cause anemia, diarrhea, and death. The most pathogenic worm species is barber pole worm or Haemonchus contortus is a blood sucker and can…

Identifying Your Fastest Growing Lambs

It’s easy to look at your lambs and pick out those that are bigger than the rest. But is that the best way to identify the lambs with the greatest genetic potential for growth? Unfortunately, selection for growth traits is not that simple because your biggest lambs are likely to be those that are single born or twin ram lambs out of a ewe in her prime. Lambs like that have had the easiest path to fast growth, but may not carry the genetics for this important trait.  Here are some things to consider when selecting for growth: Adjust your…

Experienced Polypay producer, John Anderson of Lambshire Polypays in Ohio, shares some sage advice and techniques on how he successfully lambs in the fall without the use of CIDRs or other artificial methods. John lambs exclusively in the fall now after nearly 40 years of accelerated lambing using both the STAR system and three times per year. Why lamb in the fall? There are many benefits to lambing in the fall. Fall born lambs often bring better prices at market than those born in the spring. Pasture lambing in the fall can match fall forage growth. In many parts of…

From the perspective of a long-time, full-time farmer, this article will address the topic of mature ewe size. As we seek to improve the growth and performance of our lambs, we are also producing larger adult animals. The harder we push for improved growth and performance, the faster we accelerate the trend toward bigger ewes. Big sheep catch our attention. We may have an inborn human preference for bigger animals. The bigger sheep seem superior to the small ones. They win lots of ribbons at the sheep shows. A majority of my seed stock customers purchase the biggest animals in…
