Sire Detail - BUL 18403 (Morgan)
(Picture taken as ram lamb)
We purchased Morgan from Red Barn Katahdins (BUL) in Iowa in 2018 as a ram lamb. He has grown out well here and weighed 169 pounds in December. He produced 35 lambs in 2019, 77% ram lambs, who turned out really nice, but we are hoping to see a more even distribution of ewe:ram lambs from him in 2020. We retained 5 of his ewe lambs in our flock.
He has excellent growth and maternal traits, and should do a great job increasing milk production in his ewe lambs.
His EBVs for growth are excellent with weaning weight (WWT) in the top 5% and post weaning weight (PWWT) in the top 2%. He has good parasite resistance with weaning fecal egg count (WFEC) in the top 25% and post weaning fecal egg count (PFEC) in the top 15%. His MWWT (measure of milk production and mothering of his daughters) is in the top 2%, He is in the top 25% for number of lambs weaned (NLW) and in the top 5% for the USA Hair index.
The lambs he produced in 2019 had good growth and parasite resistance and we are looking forward to seeing how his ewe lambs do as far as expression of their maternal traits go.
Below we show his NSIP (National Sheep Improvement Program) EBVs (Estimated Breeding Values).
We realize that not everybody is familiar with this.
* Data at NSIP link is updated less frequently.
Values in parenthesis below indicate where the value preceding it falls in the NSIP percentile report.
E.g. WWT 2.26 (85%) : This value is in the highest 15% in NSIP for WWT, about 85% of animals have a WWT that is lower than this value and 15% of animals have a WWT that is higher than this value.
The Radar Chart below provides an overview of where the sire EBVs are ranked on the NSIP percentile report. The 100th band is the top performing and 0th band is the bottom performing, the 50th band is the median. What is best depends on what you are looking for and what the performance of your ewes are, e.g. we do not try to maximize the NLB (number of lambs born), the 10th percentile of NLB results in about a 200% lambing rate, very high NLB is hard to support in a 100% grass/forage management system.
