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

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 35-49, January 2026.
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 ...

Optimising the Use of Cryopreserved Genetic Resources for the Selection and Conservation of Animal Populations

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 50-67, January 2026.
ABSTRACT Genetic diversity is essential for the sustainability and adaptability of populations, and is thus a central pillar of the agro‐ecological transition. However, within a population, it is inevitable that some amount of genetic variability is lost, and efforts must be made to limit this as much as possible.

Validation of the polysemen admixture on viability and acrosomal morphology of boar spermatozoa [PDF]

, 2007
Semen were collected using artificial vagina (AV), from 5 large white boars aged 2-2.5 years twice a week for 16 weeks in each of the two seasons, early rainy (ER) and late rainy (LR) seasons, to determine the effects of multiple semen pool admixture on ...

Low-Cost QCM Sensor System for Screening Semen Samples [PDF]

, 2010
Artificial insemination is a well-established part of modern agricultural practice. A viable semen sample is judged by the total number of spermatozoa (sperm) in the sample and the motility of the sperm.

Multi‐Breed Genomic Predictions for Average Daily Gain in Three Italian Beef Cattle Breeds

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 119-129, January 2026.
ABSTRACT Marchigiana, Chianina, and Romagnola are three Italian autochthonous beef cattle breeds that have been historically selected for meat production. Recent advancements suggest that the use of genomic data and multi‐breed (MB) models to combine information from different breeds may help to increase the accuracies of genomic predictions, in ...

Signature of Selection Analysis Reveals Candidate Genes Related to Climate Adaptation and Production Traits in Lao Native Goats

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 152-171, January 2026.
ABSTRACT Detecting selection footprints offers valuable insight into evolutionary processes and the mechanisms underlying phenotypic diversity in selected traits. Domestication, natural and artificial selection, and breeding have produced indigenous goats well‐adapted to their local environments, making them crucial genetic resources. Understanding the

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
