Sire Detail - GBR 8047 (Nick)

Nick is a son of Chip out of a ewe lamb sired by Midnight. This combination has brought out the best of both sires in a handsome package.


Good growth usually comes with the negatives of higher birth weight and lower loin eye muscle depth. Nick has a rare combination of lower birth weight and higher loin eye depth in proportion to his growth. He had the highest PEMD in proportion to PWWT for our 2018 lamb crop. He has excellent growth and parasite resistance while maintaining  maternal traits appropriate for our farm.

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.
