The scurs inheritance: new insights from the French Charolais breed
BMC Genetics, 2009 Background Polled animals are valued in cattle industry because the absence of horns has a significant economic impact. However, some cattle are neither polled nor horned but have so-called scurs on their heads, which are corneous growths loosely ...

Nutrition Management Strategies for the Adaptation of Cull Beef Heifers to Feedlot
New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.Providing diets with high roughage in the first days of confinement is the common way of adapting beef cattle to intensive production. However, it is possible to offer the final finishing diet from the first day of adaptation. Our objective was to compare a traditional adaptation protocol, in which animals received a diet with a higher proportion of ...

Heteroskedasticity for weaning weight of Charolais-Zebu crossbred calves
Revista Brasileira de Zootecnia, 2012 The objective of the present study was to analyze models with genetic and/or residual heteroskedasticity for genetic evaluation of the weaning weight of Charolais-Zebu crossbred calves. Weaning weight data from 56,965 crossbred calves were analyzed using

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 24-34, January 2026.ABSTRACT Genetic progress of breeding programs is highly dependent on the size of reference populations and the relatedness between reference populations and selection candidates. Many reasons can lead a population to split into several subpopulations (sanitary, physiological, political reasons, etc.).

Genetic Heterogeneity of Residual Variance for Foot Score Traits in American Angus Cattle
Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 68-78, January 2026.ABSTRACT Foot conformation is one of the main breeding goals in recent beef cattle breeding programs because it directly affects productivity, economic losses, animal welfare and longevity. Genetic heterogeneity of residual variance can be used to improve production uniformity in animal breeding programs because recent studies have shown that residual ...
