Estimation of genetic parameters for weaning and yearling weights in a composite population used to form the Purunã breed
نویسندگان
چکیده
We aimed to evaluate the effects of sex and linear quadratic components age dam at calving, as well apply a mixed model including maternal effect for genetic evaluation weaning (WW) yearling (YW) weights. The phenotypic database was composed by Charolais, Caracu, Aberdeen Angus, Canchim purebred crossbred animals. Single-trait analyses were performed using models that included WW YW traits, ignoring this [...]

Sex effects on breed of sire differences for birth, weaning, and yearling weights.
Weights of males and females can be considered to be correlated traits with different averages and variances. This study attempted to determine whether defining traits as expressed in males or in females would change estimates of breed of sire differences needed to calculate across-breed factors for adjustment of within-breed EPD to across-breed EPD. Records from the US Meat Animal Research Cen...
متن کاملEstimation of breed-specific heterosis effects for birth, weaning, and yearling weight in cattle.
Heterosis, assumed proportional to expected breed heterozygosity, was calculated for 6834 individuals with birth, weaning and yearling weight records from Cycle VII and advanced generations of the U.S. Meat Animal Research Center (USMARC) Germplasm Evaluation (GPE) project. Breeds represented in these data included: Angus, Hereford, Red Angus, Charolais, Gelbvieh, Simmental, Limousin and Compos...
