Best linear unbiased prediction to predict category frequencies of future progeny of a sire for type traits scored in mutually exclusive categories is described. The method accounts for automatic covariances among categories and is comparable to prediction for multiple traits. The method does not require linearity of measurements and also allows nonlinear economic values to be assigned to each ...

production, reproduction, management and economic parameters resulted from recordings of 5 flocks comprised of 720 heads of native goats during annual cycle of reproduction in transhumance, village and farming systems were employed to determine the performance of traits, cost-profit analysis as well as breeding objective. the overall mean for number of salable kid per goat in transhumance, vill...

Genetic effects for many dairy traits and for total economic merit are evenly distributed across all chromosomes. A high-density scan using 38,416 single nucleotide polymorphism markers for 5,285 bulls confirmed 2 previously known major genes on Bos taurus autosomes (BTA) 6 and 14 but revealed few other large effects. Markers on BTA18 had the largest effects on calving ease, several conformatio...

After years of talking about it, valuebased marketing of beef has become a reality. As a result, carcass traits are receiving increased emphasis when breeding decisions are made. There is some debate within the beef industry whether too much emphasis is being placed on the end-product. This question is raised because unit cost of production, reproduction, and early growth are still the factors ...

The Stability of Big-Five Personality Traits We use a large, nationally-representative sample of working-age adults to demonstrate that personality (as measured by the Big Five) is stable over a four-year period. Average personality changes are small and do not vary substantially across age groups. Intraindividual personality change is generally unrelated to experiencing adverse life events and...

For chicken, the study about fat-related traits is one important aspect of the breading and economic benefit. The intramuscular fat can enhance the taste and flavor of muscle, and study of chicken on the level of DNA has become into a research spot for modern biologics. In this article, we summarized deeper research developments of fatty acid-binding protein gene (FABP), leptin receptor gene (O...
