Evaluating the Predictive Value of Estimated Breeding Values of Piétrain Sires for Uniformity and Survival in Their Crossbred Progeny

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT High litter sizes in pigs are associated with lower birth weights and increased within‐litter variation, which poses challenges to pig farming. Improving piglet uniformity and survival via genetic selection of terminal boars could be a strategy to enhance these traits.

Genetic Control of Canalization for Twinning Rates in Polypay and Rambouillet Sheep Using Threshold or Double Hierarchical Generalized Linear Models

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In most sheep production systems, the ideal scenario is for every ewe to lamb and successfully raise twins. However, selection for increased number of lambs born (NLB) is often accompanied by a higher incidence of triplet and higher‐order births, which increases management challenges and producer reluctance to intensify selection for this ...

Genetic Associations of Functional Longevity With Sexual Precocity and Growth Traits in Nellore Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Functional longevity (FL) is a complex trait that integrates many attributes directly contributing to the successful retention and productivity of a cow within the herd. Consequently, improving FL in beef cattle increases herd profitability. This study aimed to estimate the genetic associations between two alternative FL definitions and traits

Genetic Evaluation for Functional Longevity in Nellore Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Stayability (STAY) presents limitations in capturing genetic variability among animals with varying calving records up to 76 months of age. Furthermore, because STAY is measured late in life (typically at 6 years of age), it inherently prolongs generation intervals.
