EBVs are tools that producers can use to select breeding animals that will help them meet flock goals for specific traits such as growth, milk, reproduction, parasite resistance and carcass quality. It is important to understand that selecting for extremes in one trait will often put negative selection pressure on
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.
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
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
This past summer, Dr. Scott Bowdridge, Associate Professor of Food Animal Production, West Virginia University, opened our minds to his exciting research identifying immune mechanisms in sheep to eliminate parasitic infections. At the 2022 Eastern Alliance for Production Katahdins (EAPK) symposium he discussed his data that links low FEC EBVs
For our fourth and final producer forum we asked our four shepherds to share some words of wisdom. As usual, their answers are as varied as their production systems and geographic location. What has your experience taught you over the years and what nuggets or advice would you share with
Sheep GEMS is roaring ahead, with the strong commitment by Katahdin breeders particularly welcomed. With the help of John Bare, Michelle Canfield, Tom Hodgman, and Jim Morgan—members of a Project Advisory Group—twenty-six Katahdin flocks have voiced their interest to participate in this project. A key element of Sheep GEMS is
Katahdin producers who use NSIP estimated breeding values (EBV) to make selection decisions on replacements for the home flock or for sale often select for more than one trait at a time. In fact, most breeders search for the perfect animal with balanced EBVs, or those that excel in all
Breeding season is here and if you want to add lambs to your flock next year you are going to need a ram. Timing your lambing to suit your schedule requires you to keep a ram separate until you’re ready to introduce him to your ewes. Keep in mind, rams
For our third producer forum we asked our four shepherds, all enrolled in NSIP, how they select their breeding rams and how they make breeding decisions on their farms. Their answers, shared below, reflect the differences among the farms in environment, markets, individual flock goals and management styles. As a
Gestation in sheep varies from 142 to 152 days with the average being 147 days. Just like people, individual pregnancies can vary, gestation periods of 138 to 159 days are not unheard of. Ewes carrying multiple lambs tend to have shorter gestations while male lambs (and heavy birth weight lambs) are usually carried for longer than female lambs. The form above calculates the lambing date based on a 147 day gestation period.
