Genomic Evaluation in Nellore Cattle for Reproductive Traits: Multiple Ways to Account for Missing Pedigrees

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Missing pedigrees are a common problem in most populations. Animals with unknown ancestors are usually treated as founders; however, this can underestimate inbreeding, not properly account for different base populations, and bias breeding values.

An Increase in Male Recombination Rate With Age in Dairy Cattle Is Heritable and Polygenic

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Meiotic recombination is an essential process for shuffling genetic diversity in sexually reproducing organisms, can vary within and between individuals in response to intrinsic and extrinsic factors, and can be heritable. Interestingly, recombination rate has been found to vary with age in some species, but to date, there have been no ...

Genetic Heterogeneity of Residual Variance for Foot Score Traits in American Angus Cattle

Journal of Animal Breeding and Genetics, EarlyView.
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 ...
