Sire Detail - GBR 9110 (Peter)
(Picture taken as young ram lamb)
Peter is a 2019 ram lamb out of Morgan and Chloe, one of my favorite ewes. His dam is an excellent mother and we have kept most of her daughters in our flock. She is a very prolific ewe who produced two sets of triplets and had quadruplets in 2019. On the same day Peter was born we had another ewe with stillborn lambs, so we fostered two of his siblings to her so Chloe did not have to raise quadruplets on only grass.
Peter brings excellent growth, good parasite resistance and very high maternal traits. We used him as the clean up ram.
His EBVs for growth are good with weaning weight (WWT) in the top 25% and post weaning weight (PWWT) in the top 20%. He has good parasite resistance with weaning fecal egg count (WFEC) in the top 20% and post weaning fecal egg count (PFEC) in the top 15%. He is in the top 10% for number of lambs born (NLB) and in the top 20% for number of lambs weaned (NLW). He is in the top 25% for USA Hair index

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.
