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, 2019 and 2020 lambing.
Even though Midnight excels in growth he is not a huge ram. He weighed 230 pounds in December. He is getting older now, but even in his prime he only weighed 260 pounds. This is something we really like, we want lambs that grow to butcher weight quickly but we do not want huge ewes. Midnight brings excellent growth in his lambs but his adult ewes in our flock are moderate framed and weigh about 150 pounds.
The majority of his 2017-2019 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 used for breeding last year and this lambing. Pitbulls lambs turned out really nice, so much so that we are using one of his sons for breeding this year.
Midnight has EBV's for weaning weight and post weaning weights in the top 1% in NSIP. His EBV for parasite resistance at weaning (WFEC) is in the top 35% and parasite resistance post weaning (PFEC) is in the top 45%. He does produce lambs with higher birth weights and that is why we do not breed him to our ewe lambs.
Midnight made the Katahdin Proven Sire Trait Leader List for two traits in 2019. (July 2019 EBVs of sires with offspring in NSIP):
Ranked number 8 on the list for Weaning Weight
Ranked number 7 on the list for Post Weaning Weight
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 over a 200% lambing rate on our farm, very high NLB is hard to support in a 100% grass/forage management system.
