Registered Katahdin Hair Sheep Breeding Stock

We sell a small number of ram lambs and ewe lambs as breeding stock each year. We want to test the lambs as thoroughly as possible, for our own selection as well as for the customers that purchase from us. We make our final selection of breeding stock to keep and buy towards the end of September / beginning of October. That gives us enough time to measure growth, maternal traits, parasite resistance and carcass traits.

​

We measure and collect the following:

  • Number of lambs born and weaned

  • Birth, 60 day (WWT), weaning, early post-weaning (PWWT) and post-weaning weights (PWWT)

  • Scrotal Circumference (PSC) on a large group of ram lambs

  • At least one fecal egg count, preferably two on each lamb

  • Loin eye depth (PEMD) and fat (PFAT) on a larger group of ram lambs

​​

This takes, not just work time but also calendar time because animals have to a certain age before some of these measurements can be taken.

All breeding stock for 2024 has been reserved

Estimated Breeding Values (EBVs)

  • BWT - Birth Weight (Top / 100th percentile is highest BWT)

  • WWT - Weaning Weight (Top / 100th percentile is highest WWT)

  • MWWT - Maternal Weaning Weight (Top / 100th percentile is highest MWWT)

  • PWWT - Post Weaning Weight (Top / 100th percentile is highest PWWT)

  • WFEC - Weaning Fecal Egg Count (Top / 100th percentile is best WFEC)

  • PFEC - Post-Weaning Fecal Egg Count (Top / 100th percentile is best PFEC)

  • PFAT - Post-Weaning Fat Depth (Top / 100th percentile is lowest PFAT)

  • PEMD - Post-Weaning Eye Muscle Depth (Top / 100th percentile is largest PEMD)

  • PSC - Post-Weaning Scrotal Circumference (Top / 100th percentile is largest PSC)

  • NLB - Number of Lambs Born (Top / 100th percentile is highest NLB)

  • NLW - Number of Lambs Weaned (Top / 100th percentile is highest NLW)

Sires of 2024 Lambs

We used 7 rams for ideal pairing an one ram as a cleanup. Overall we used a relatively young group of rams for this years breeding.
