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…

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…

When the breeding season starts, there is an implied contract between shepherd and ewe. Your commitment to keep her around for another production cycle means her commitment to return her annual costs plus some in lamb production. To do this, she must get pregnant, lamb, and wean a litter that is a relatively high percentage of her own body weight. Getting pregnant is the first step. Ewes that breed and conceive early in the season have a greater chance of weaning a heavier litter. They also contribute to a shorter lambing season, improve lamb crop uniformity, and reduce shepherd fatigue.…

Blending Technology & Tradition to Achieve Breeding Goals

We talk a lot about tradition in the American sheep industry. Traditions aren’t stagnant, they get modified from one generation to the next as new information and insights are gained. Nearly everything in modern sheep production – be that fences, milk replacer or RFID readers – was at one time a state-of-the-art technology. Whether we choose to adopt a new technology is dependent on economics and those intangibles that define our unique perspectives for raising sheep in the first place.From the dawn of sheep domestication until the last 50 years or so, the only available technologies to select replacement animals…

Dr. Charles Parker (1935-2024) was a sheep specialist, researcher, industry leader and experienced advisor to many of us in the Katahdin breed. As an early supporter of the breed, Charles felt that Katahdins could and should be the Complete Meat Sheep, genetically balanced for reproductive and growth efficiency and easily adapted to diverse production systems. Following his death in July 2024 we decided to compile some of his advice and guidance over the years to share with others. In collaboration with the Piel Farm, Heifer Project and some of the early Katahdin breeders, Charles was instrumental in the development of…

Preparations for Breeding

The joining of ewes and rams at breeding time seems like a relatively simple task, but there are a lot of important steps that need to be taken several weeks before breeding that can affect both the quality and quantity of next year’s lamb crop. Breeding ewes that are in poor condition can result in fewer eggs fertilized, embryonic abortion, poor fetal development and weak newborns. Rams that are in poor condition may have difficulty servicing ewes resulting in open ewes or a long lambing season. Preparations initiated 4-6 weeks before introducing rams can maximize success during breeding and lead…

Buying Parasite Resistance: considerations for greater success

Often producers interested in adding genetics for parasite resistance to their flock are faced with deciphering the fecal egg count (FEC) EBVs listed on a stall card or catalog at an auction (online or in person). Is that enough information to identify a parasite resistant animal? In my experience, no. Estimated Breeding Values (EBVs) provide a wonderful tool to predict animal performance, but when it comes to parasite resistance, the stated EBV often doesn't provide the whole answer. More than other traits, FEC EBVs can be subject to some pretty big changes over time. Partly that's because there is such…

We often get asked "Where's the best place to buy sheep?" A lot depends on your goals and what you'll use the sheep for, but one thing is pretty much certain: Don't buy sheep from the local sale barn. Below are some of the more common sale venues with some of the pros and cons listed. Venue Pros Cons On Farm Often lowest cost option Least chance of biosecurity issues Least stress for animals Ability to inspect the whole flock and observe management Potentially more choices of one farm's genetics May allow better opportunity to develop relationship with seller, especially…

Understanding “Number of Lambs Weaned” (NLW) Estimated Breeding Values

We've been members of NSIP since 2006 and I must confess that I've never really understood what all went into the calculation of "Number of Lambs Weaned", let alone Genomically-enhanced Estimated Breeding Values (GEBV) for NLW. Seems most of my ewes had NLW GEBV that were about the same as their NLB GEBV, with a few exceptions. Some were a little lower and some were a little higher, and since they are correlated, I didn't pay a whole lot of attention to these slight differences until I bought a ram last year with a NLB of 0.04 and a NLW…

In 2022, the Southwest Virginia Agricultural Research and Extension Center hosted its 10th ram test and sale. Over the years, the program has developed a strong reputation for the development and identification of superior rams for growth and parasite resistance in a forage-based environment. Historically, the test has included rams from NSIP flocks and some rams from flocks not enrolled in NSIP (non-NSIP). The 2022 test and sale data were analyzed to explore the impact of NSIP enrollment on ram performance and value in the program. The 2022 test included 119 rams from 10 states. Rams were delivered in late…
