January 11, 2016 – Genomic selection can greatly improve breeding programs. Genomic selection has been made possible by sequencing large numbers of single nucleotide polymorphisms (SNP; variations at a single nucleotide marking a specific position in the genome). Then, these markers covering the whole genome can be used to predict (with high accuracy) many breeding values and traits. Read more
Most sheep producers would prefer to avoid pregnancy losses, but that can be tough when they do not know the cause behind the loss. So whose fault is it? The dam? The sire? The embryo?
In an article recently published in the Journal of Animal Science, New Zealand researchers use statistical analysis to determine the most probable causes of pregnancy failures in sheep. Researchers evaluated data collected from over 11,000 records on ovulation rates and litter sizes at AgResearch’s Woodlands Research Centre from 1988 to 2006. Read more

Sheep producers in western states can get a better idea of which breeds are best suited for their operations, based on a comprehensive evaluation by Agricultural Research Service (ARS) scientists of the animals used to produce market lambs.
The ARS scientists and their university colleagues examined critical performance traits of lambs sired by rams of Columbia, Suffolk, Texel and a composite breed developed at the ARS Roman L. Hruska U.S. Meat Animal Research Center in Clay Center, Neb. Read more
