Evaluation of Crossbreeding Systems for Preweaning Traits in Beef Cattle
SUMMARY four-generation crossbreeding experiment with Hereford, Angus a from a tt1e were analyzed. Individual, maternal, and grand-maternal rthorn c: rotic effects on the composite trait of calf weight weaned per I e and h\~eeding and its component traits were evaluated.

متن کاملAssociation of the muscle hypertrophy locus with carcass traits in beef cattle.
A locus near the centromere of bovine chromosome 2 is responsible for muscle hypertrophy (mh) in cattle. The objectives of this study were to refine the genomic region in which the locus resides and to assess the effects of a single copy of the mh allele on carcass and birth traits. Two half-sib families were developed using a Belgian Blue x MARC III (n = 246) or a Piedmontese x Angus (n = 209)...
متن کاملEstimation of Genetic Parameters for Carcass Traits and Their Corresponding Ultrasound Measurements in Crossbred Beef Cattle
and Implications Variance parameters including heritabilities, genetic and residual correlations are required for national cattle evaluation. There are huge amounts of data available for estimating such variance parameters for growth traits, but much less data is available for carcass traits. In this study, heritabilities and genetic correlations were estimated using restricted maximum likeliho...
متن کاملGenetic and phenotypic parameters for carcass traits of American Shorthorn beef cattle.
Carcass measurements were taken on 1,292 steers and collected by the American Shorthorn Association. The sires were purebred or appendix-registered Shorthorn. Because all dams were not Shorthorn, genetic fractions of breeds of origin were determined for each dam. Measurements for hot carcass weight; dressing percentage; fat thickness; ribeye area; kidney, pelvic, and heart fat (KPH); marbling; ...
متن کاملGenetic Parameter Estimates of Carcass Traits under National Scale Breeding Scheme for Beef Cattle
Carcass and price traits of 72,969 Hanwoo cows, bulls and steers aged 16 to 80 months at slaughter collected from 2002 to 2013 at 75 beef packing plants in Korea were analyzed to determine heritability, correlation and breeding value using the Multi-Trait restricted maximum likelihood (REML) animal model procedure. The traits included carcass measurements, scores and grades at 24 h postmortem a...
