Different estrous induction methods during the non-breeding season in Kivircik ewes

Veterinární Medicína, 2006
The efficiency of medroxyprogesterone acetate (MAP) sponges in combination with either pregnant mare serum gonadotrophin (PMSG) or cloprostenol (PGF2α) for inducing and synchronizing the estrous cycle in non-lactating Kivircik ewes was investigated ...

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 508-523, July 2026.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Therapeutic Effect of Zingerone on Reproductive Damage in Diabetic Male Rats: Potential Role of Sirt1/Nrf2/HO‐1 and Bax/Bcl‐2 Signaling Pathways

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
Diabetes mellitus causes significant damage to the male reproductive system. Sirt1/Nrf2/HO‐1 signaling pathway acts as a line of defense against ROS in reproductive organs. In STZ‐induced diabetic rats, the proapoptotic Bax protein expression was found to be elevated, whereas the antiapoptotic Bcl‐2 protein expression was reduced.

Effects of Fluorescence‐Activated Cell Sorting on Boar Sperm Motility Subpopulations and In Vitro Embryo Development

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
Effects of fluorescence‐activated sperm sorting on IVF outcomes and motility subpopulations. Distinct boar ejaculates were either used directly for in vitro fertilization (IVF; control, unsorted) or processed by fluorescence‐activated cell sorting to generate a sorted sperm population.

Evaluation of bovine leukaemia virus infection control measures in Japanese Black beef cattle breeding farms: A 7‐year longitudinal study based on proviral load

Veterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background Bovine leukaemia virus (BLV) infection remains a major problem for Japanese Black (Wagyu) cattle, and effective and sustainable control measures are essential to prevent its spread in breeding herds. This study aimed to monitor the BLV infection status of all cattle at a Japanese Black breeding farm in Kagoshima Prefecture, Japan ...

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

Enhancing post-thaw sperm quality in rams: quinic acid as a natural antioxidant

Frontiers in Veterinary Science
IntroductionThis study investigated the effects of quinic acid (QA) supplementation at different concentrations (Control, 50, 100, and 200 μg/mL) on the post-thaw quality of ram semen, with a focus on motility, DNA integrity, flow cytometric parameters ...

Impact of Female Mating Status on Male Courtship Behaviour in a Sexually Cannibalistic New Zealand Fishing Spider

Ethology, Volume 132, Issue 6, Page 373-384, June 2026.
Scoring of male courtship behaviour in Dolomedes minor revealed no effect of female mating status on courtship duration or sequence structure, but males delayed the initiation of courtship when encountering previously mated females. ABSTRACT The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also
