Breeding Objectives Indicate Value of Genomics for Beef Cattle
A well-defined breeding objective provides commercial producers a mechanism for extracting value from the investment in genomics by seedstock producers. Advantages of genomic prediction include increased accuracy of expected progeny differences (EPDs) for traits that have been components of routine genetic evaluations. Perhaps more importantly, genomic prediction makes it possible to include tr...
متن کاملBreeding objectives for beef cattle in Ireland
Breeding objectives for beef cattle in Ireland were derived and used to define selection sub-indexes. The intention of the sub-indexes was to simplify selection decisions by commercial bull and semen buyers for situations where all of the resulting progeny are slaughtered, or when some female progeny are kept as replacement breeding cows. Separate sets of economic values for calving ease and ge...
متن کاملBreeding and Genetics: Beef Cattle
The association of a single nucleotide polymorphism (SNP) of calpain 1 (CAPN1) gene with shear force of 2.54 cm steaks from M. longissimus dorsi from Gannan yaks (Bos grunniens, n = 181) was studied. The experimental design was a repeated measures with the main unit in a completely randomized design with a factorial arrangement of treatments (age at harvest x SNP) and the repeated subunit was a...
متن کاملBreeding and Genetics: Beef Cattle
Bovine infectious keratoconjunctivitis (BIK, pinkeye) is an economically important illness affecting growth of calves. The primary objective of this study was to estimate genetic parameters for BIK in beef calves prior to weaning. Health records of 47,880 calves born at the Meat Animal Research Center, Clay Center, NE from 1983 through 2001 were evaluated. Cows and calves were monitored daily f...
