Genetic Parameters in Merino Sheep GENETIC RELATIONSHIPS BETWEEN CARCASS QUALITY AND WOOL PRODUCTION TRAITS IN AUSTRALIAN MERINO RAMS
The heritability of carcass quality traits and the genetic correlations between wool production and these carcass quality traits were estimated on 1216 Merino rams. The results showed that carcass quality traits are moderately heritable but pH appears to be lowly heritable. Yellowness and redness of L. dorsi had very low heritability estimate. Moderate negative genetic relationships were found ...
متن کاملGenetic association of growth traits with carcass and meat traits in Nellore cattle.
The aim of this study was to estimate genetic and phenotypic associations of growth traits with carcass and meat traits in Nellore cattle. Data from male and female animals were used for weaning weight (WW; N = 241,416), yearling weight (YW, N = 126,596), weight gain from weaning to yearling (GWY, N = 78,687), and yearling hip height (YHH, N = 90,720), respectively; 877 male animals were used f...
متن کاملGenetic and Phenotypic Correlations between Performance Traits with Meat Quality and Carcass Characteristics in Commercial Crossbred Pigs
Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex and batch), covariates (birth weight, cold carcass weight, and age), random effects (additive, litter ...
متن کاملEstimates of Genetic Correlations between Carcass and Growth Traits and Scrotal Circumference in Nelore Cattle
INTRODUCTION The demand for high quality meat and the competition with other protein sources imposes the introduction of new technologies in the Brazilian beef cattle system of production. Most of breeding evaluation programs in Brazil, have given emphasis to records of weights and scrotal circumference (SC) at different ages, ignoring carcass traits (CT) and other growth traits. Carcass traits...
متن کاملGenetic Parameters for Growth Traits of the Hungarian Merino and Meat Sheep Breeds in Hungary
Heritabilities and genetic correlations between weaning weight (WW) and average daily gain (ADG) for the Hungarian Merino, Ile de France, Charollais, German Mutton Merino, German Blackheaded, Texel, Fleisch Merino and Suffolk were studied. The selection of replacements is based on the two traits. The amount of records provided by the Hungarian Sheep Breeder’s Association and by the Hungarian Ag...
