A healthy Ontario sires program has made it possible for local breeders and owners to have a taste of racing's riches.
Records were available for birth and (or) weaning weights of 36 949 lambs from 123 flocks that were evaluated in 1988 through 2011; these flocks participated in the NSIP Terminal Sire Breed evaluation program [ 3] and were maintained in the Australian Sheep Genetics LAMBPLAN database [ 4].
This indicates that the cryo-bank bulls are good candidates as sires in a breeding program aimed at avoiding inbreeding.
Figure 4 illustrates how accurately the different programs allocated the sire's strands to each half-sib.
Genotypes for each offspring and all possible sires were analyzed with the program Cervus [ 21], which assigns paternity using a likelihood method.
Following these importations, Tankersley began to build her breeding program around two Crabbet sire lines, which she called the "Double R" cross.
Therefore, in a breeding program, the use of individual sire genotypes to predict heterosis may only be worthwhile if individual sire genotypes are already available as a result of routine genotyping.
One trivial alternative possibility is that this program simply reflected a sire-based genetic effect independent of direct contribution to the muscling EBV status.
The objective was to compare pregnancy per AI (P/AI) with conventional (CON) or sex-sorted (SS) semen from a single sire within a fixed-time AI (FTAI) program designed for dairy heifers.
Although he did not sire a great number of horses, the linebreeding program that Wiescamp followed led to the products of that program often being called "Skipper W horses".
