Cryopreservation of ram semen: baicalein efficiency on oxidative stress, chromatin integrity, viability and motility post thaw

Frontiers in Veterinary Science
Baicalein (B) has potential antioxidant properties, but it has not been tested as a ram semen extender. This study aimed to assess the impact of B on various sperm parameters and determine its potential influence on semen quality after the freeze-thawing

Molecular Regulation of Post‐Hatching Embryo Development: Implications for Early Pregnancy Losses in Livestock Species

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Pregnancy loss (PL) remains a major limitation to reproductive efficiency in livestock, with a substantial proportion originating during early embryo development, particularly between blastocyst hatching and implantation. This developmental window encompasses complex processes of lineage differentiation and morphogenesis. Accumulating evidence

A Low Concentration of a Sustainably Obtained Blueberry Extract Improves the Post‐Thawing Motility of Cryopreserved Bull Spermatozoa

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Natural extracts could improve sperm storage and artificial insemination (AI). This study, for the first time, evaluates the suitability of a blueberry extract (Vaccinium corymbosum), obtained from pomace using a sustainable methodology, as a supplement for bull semen extenders.

Comparative Susceptibility of Donkey and Horse Sperm to Liquid‐Storage Temperature

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Preservation protocols for donkey sperm are based on those developed for horses, despite potential interspecific differences in cooling tolerance. This study compared horse and donkey sperm during long‐term storage at 5°C and 17°C. Ejaculates from four stallions and four jacks (n = 16) were centrifuged, resuspended in skimmed milk‐based ...
