Sire Detail - WHK 1352 (Midnight)

We bought a group of ewe lambs in 2015 and noticed that a few had superior parasite resistance. When looking at the pedigrees we noticed that they all shared the same sire, WHK 1352 (Midnight). Luckily we were able to purchase him and used him for the first time to sire some of our 2017 lambs. We were very happy with his lambs and used him again for 2018 lambing.

The majority of his 2017 and 2018 lambs show above average growth and parasite resistance and we retained a lot of his ewe lambs in our breeding program. We used his son GBR 7112 (Moon) as a sire for our 2018 lamb crop and retained most of his ewe lambs in our flock. Moon moved to Misty Oaks farm in Ohio last fall. GBR 8202 (Pitbull) is also a Midnight son that we are using for breeding this year, we hope that he will be as successful as his brother.

Midnight has EBV's for weaning weight and post weaning weights in the best 1 % in NSIP. His fecal egg count EBV's are also in the best 15% in NSIP. He does produce lambs with higher birth weights and that is why we do not breed him to our ewe lambs.

Values in parenthesis below indicate where the value preceding it falls in the NSIP percentile report. 

E.g. WWT 2.3 (15%) : This value is in the top 15% in NSIP for WWT, about 15% of animals have a WWT that is equal or better than this value and 85% of animals have a WWT that is worse than this value.

Percentile Summary

The Radar Chart below provides an overview of where the sire EBVs are ranked on the NSIP percentile report. The 0th band is the top performing and 100th 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 90th percentile of NLB results in about a 200% lambing rate, very high NLB is hard to support in a 100% grass/forage management system.
