Impact of Astaxanthin Concentration in Extender on Sperm Kinetics and Lipid Peroxidation After Cryopreservation in Beef Bulls

Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.
ABSTRACT Cellular damage caused by changes in temperature and osmolarity during cryopreservation primarily results in excessive generation of reactive oxygen species (ROS). These damages compromise the plasma membrane and reduce sperm fertility. Antioxidants help mitigate these effects.

Annual Variation in Stallion Testicular Measurements and Its Association With Hormonal Profiles and Semen Quality

Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.
ABSTRACT In a stallion breeding‐soundness examination, testicular volume may be estimated either from total scrotal width or by measuring the height, width and length of both testes. This study aimed to determine whether testicular morphometric parameters obtained by ultrasonography fluctuate throughout the year, and whether these variations affect ...

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).
