Application of Genomic Random Regression Models for Genetic Parameter Estimations of Female Fertility Traits in Different Parities in German Holsteins

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 377-389, May 2026.
ABSTRACT The aim of the present study was to infer genetic (co) variance components and to estimate parity‐specific breeding values for the female fertility traits non‐return rate after 56 days, the interval from calving to first service and days open by applying random regression models on a time‐dependent parity scale. In this regard, we considered a

Unmated Queens Show Worker‐Like Behaviour and Gene Expression in Polygynous Colonies of the Ant Stigmatomma pallipes

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Insect societies show a reproductive division of labor between egg‐laying queens and workers that fulfil all non‐reproductive tasks. Polygyny, the coexistence of several queens in a colony, has evolved multiple times in social insects. Although queens in polygynous colonies are often assumed to have similar reproductive outputs, they may ...

Generation of Cloned Sheep Lacking Galactose‐α1,3‐Galactose and N‐Glycolylneuraminic Acid Antigens

open access: yesXenotransplantation, Volume 33, Issue 3, May/June 2026.
ABSTRACT Livestock have long been regarded as a potential source of donor organs to alleviate the global organ shortage for transplantation. Sheep have a similar anatomy to humans, providing the standard model for demonstrating biocompatibility and performance of biological heart valves to obtain regulatory approval for their use in transplantation ...
