Unravelling Twin Births in German Holstein Cows: Phenotypic Associations, Genetic Analysis and Potential Underlying Genes and Hormones

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Twin births in dairy cattle are rare but present significant challenges for animal welfare, as both the health of the cow and the calves are affected. This causes economic losses, which prompts breeders to select against twin births and identify associated risk factors.

Single‐Step Genomic Predictions for Growth and Carcass Traits in Nordic Charolais and Hereford Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In order to investigate the applicability and efficiency of genomic selection for growth and carcass traits in Nordic beef cattle, single‐step genomic BLUP (ssGBLUP) was applied in 4321 Charolais and 4532 Hereford animals with information on approximately 43,000 SNPs each.

Coercive mating has no impact on spatial learning, cognitive flexibility, and fecundity in female porthole livebearers (Poeciliopsis gracilis)

Journal of Fish Biology, EarlyView.
Abstract Coercive mating is a sexual selection strategy that is likely to influence female cognition. Female harassment levels have been linked to altered brain gene expression patterns and brain size evolution, suggesting females may respond to coercive mating by investing energy into “outsmarting” males.
