Genomic evaluation of health traits in dairy cattle
There is growing interest from dairy producers in traits related to health and fitness of cattle, which often have low heritabilities but high economic values. Traits with low heritability can be improved by genetic selection, but large numbers of daughter records are required to produce predicted transmitting abilities with high reliability. Producer-recorded health event data collected from o...
متن کاملBayesian threshold-linear model for genetic evaluation of direct and maternal calving traits in Iranian primiparous Holstein cattle
The main objective of this study was to estimate the genetic parameters for multi-trait evaluation of birth weight (BW), gestation length (GL) and calving difficulty (CD) in first-parity Iranian Holstein dairy cattle. The data included 29,950 calving records collected during 1995 to 2014 by the Animal Breeding and Improvement Center of Iran. A threshold-linear sire-maternal grandsire model was ...
متن کاملGenetic and Economic Aspects of Applying Embryo Transfer in Traditional and Genomic Evaluation in Iranian Holstein Dairy Cattle
Embryo transfer (ET) in Holstein dairy cattle became an important commercial enterprise after the introduction of non-surgical recovery technique. Embryo transfer could increase the reproductive rate of genetically superior cows. The objectives of the present study were to evaluate the use of ET in Iranian Holstein dairy cattle to increase selection intensity on the dam side, economically; esti...
متن کاملQuantitative trait loci affecting calving traits in Danish Holstein cattle.
The objectives of this study were 1) to detect quantitative trait loci (QTL) affecting direct and maternal calving traits at first calving in the Danish Holstein population, 2) to distinguish between pleiotropic and linked QTL for chromosome regions affecting more than one trait, and 3) to detect QTL affecting stillbirth and calving difficulties but not calf size that could be used in selection...
متن کاملMyocardial epithelial inclusions in a Holstein calf
Epithelial inclusions were detected in myocardium of a 2-month-old male Holstein calf. Microscopically,nonpurulent myocarditis along with focal tubular and acinar structures covered with cuboidal epithelial cellswas seen in the myocardium. Most tubular and acinar structures stained with Masson’s trichrome were foundto be surrounded with a dense collagen. Tubular and acinar structures had PAS po...
