Management Intensive Grazing

I realized the benefits of grazing early on in my livestock career. Most everybody that I knew had animals on grass; it was the confinement operations that seemed so farfetched to me. It wasn’t until I heard someone talking about a form of rotational grazing called “Management Intensive Grazing” or “MIG” that I started to think about grazing in a whole new way. Instead of just turning animals into a pasture and letting them eat all that was there, even though most of the time that wasn’t much, you would just give the animals a small portion of the pasture…

Sheep GEMS News Brief 10 – February 2025 In the last Sheep GEMS news brief, we presented the economics of subclinical mastitis in meat and wool ewes. Despite the major production impact that subclinical mastitis poses, the only way to diagnose it involves collecting and testing milk from every ewe. Take it from the guy who has milked the rankest Rambouillet and most cantankerous Katahdin ewes, you don’t want to go down that road! So, we’re at a bit of an impasse; we have a disease that costs us money, but we don’t know which ewes have it. How can…

Fall Lambing Considerations

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…

 Using CIDRs for Precision Management

The use of estrus synchronization has many benefits. The timing and length of the breeding season is directly related to the timing and length of the lambing season. A more concise breeding season will result in a more concise subsequent lambing season. This can improve labor efficiency (minimize the number of nights you have to check the barn), improve uniformity of the lamb crop, increase average age and weight of the lamb crop, and allow for more grafting opportunities if needed. Additionally, if we know within a few days when the majority of lambs will be born, we can better…

Sheep GEMS News Brief 9 – January 2025 A nationwide survey conducted in 2011 by the USDA APHIS estimated that 14% of U.S. ewes (402,000 head) are culled each year. Of ewes culled, 56% are removed for old age. Culling for age is a good thing as these ewes have been productive for years, but we have limited resources and need to make room for younger, genetically superior females. The flip side is that 44% of cull ewes leave the flock early, which is not a good thing. The most common reasons for culling ewes prematurely are failure to lamb…

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…

“I do what is best for the grass and that is good for the sheep too.” says Tom Perkins, who grazes his sheep 365 days a year on his farm in Fombell Pa. ‘Big Tom,’ as he is known, runs his 150 registered Katahdin ewes on 70 acres of owned land and eight acres of leased ground. On Big Tom’s Con-O-Creek Farm, he has created a unique system utilizing both fields and barn for optimal production. Big Tom grew up on his family’s farm milking cows until the mid ‘80’s when the farm was transitioned to a beef cattle operation.…

Efficacy of a Novel Herbal Dewormer on Katahdin Lambs

Introduction: Most shepherds are familiar with the need to deworm their sheep and the added stresses that go along with it. Over time, the Barber Pole Worm and other economically devastating parasites have become more resistant to conventional dewormers, creating a quickly growing need for alternative deworming practices. An effective herbal dewormer could be a solution available to sheep farmers, especially those using organic practices. During the summer of 2022, for our senior capstone study at the University of Maine, we tested the novel herbal dewormer Early Bird to evaluate whether it was an effective option. Early Bird is a…

Sheep GEMS News Brief 8 – Early December 2024 The genetic diversity available within each sheep breed gives us tremendous opportunity to make genetic improvement. That snapshot of the genetic diversity currently available is extremely valuable since it provides a benchmark for comparing the consequences of selection over time in individual breeds. To establish that starting point, we used both pedigree- and molecular-based information to assess genetic diversity in the four breeds involved in Sheep GEMS. For each of the breeds we evaluated—Katahdin, Polypay, Rambouillet, and Suffolk—we found substantial genetic diversity. That coincides with low inbreeding levels. So, what do…

EBVs of different animals can be directly compared with each other, but how do they compare to the rest of the sheep in NSIP? The Percentile Report, generated by NSIP, is a tool that allows you to evaluate individual animals, set breeding goals, help with marketing and sales, as well as to understand what is available in the breed. As a producer you need to know how to read the Percentile Report, explain it to customers and know what data goes into calculating the percentiles. Note: This article uses the NSIP Katahdin Percentile Report that was generated on 12/18/2024. Percentile…
