Summary: Gonadal soma-derived factor (gsdf) is critical for sex determination and differentiation in fish, but its functions in spermatogenesis are unclear. This study found that XY gsdf/Nile tilapia can be converted to males by inhibiting estrogen synthesis, and these male fish are infertile. Transcriptome analysis revealed dysregulation of genes related to the endocrine system and azoospermia in these infertile fish. These findings provide a foundation for future research on the role of gsdf in spermatogenesis in fish.

Summary: This study measured the major long bones of red junglefowl and domestic fowl to compare the osteological differences between wild and captive red junglefowl. The findings suggest that captive red junglefowl are generally smaller than wild ones, with a thicker distal part of the tibiotarsus and thinner parts of the wing bone. These differences indicate that body size reduction and other morphological changes occurred in the early stage of domestication.

Summary: This small-scale experimental study found that giving chicks the possibility to express choices between different variants of the same resource could improve their ability to cope with challenges and make the most of new opportunities. Chicks with access to different types of litter and perches were found to be less fearful, less chronically stressed, and better prepared to cope with pathogenic challenges. Additionally, they exhibited improved learning ability. These findings suggest that providing chicks with access to variation in relevant resources could enhance their adaptive capacities and resistance to infection.

Summary: Reproductive failure is a major obstacle to recovery in many endangered species, including the critically endangered kakapo bird. Recent studies show that fertilization failure is rare in non-threatened bird species, but distinguishing between causes of fertilization failure and embryo death is crucial for conservation management. This study on kakapo eggs found that the majority were fertilized, providing a more accurate estimate of fertility in a wild population, and also demonstrated that artificial insemination can result in more sperm reaching the egg in a wild bird species.

Summary: Avian hatching failure is a widespread phenomenon, affecting about 10% of eggs that are laid and not lost to predation, damage, or desertion. Our understanding of hatching failure is limited in terms of its mechanisms and occurrence across populations. Threatened species and captive populations are more likely to experience higher rates of hatching failure, but these differences have rarely been quantified and broader patterns remain unexplored.

Summary: The presence of a more efficient glycolysis mechanism depending on pyruvate in stallion spermatozoa can counteract the detrimental effects of higher glucose concentrations. Incubating spermatozoa with 10 mM pyruvate in a modified Tyrode's media with 67 mM glucose showed increased motility and maintained viability. This improvement is attributed to the conversion of lactate to pyruvate and increased NAD(+) enhancing glycolysis efficiency.

Summary: This study found that Nobiletin (NOB) can promote the cryosurvival and embryo development of porcine sperm after in vitro fertilization (IVF). The addition of NOB improves sperm motility, acrosome integrity, viability, and mitochondrial membrane potential, reduces lipid peroxidation, and increases cleavage and blastocyst formation rates. Furthermore, NOB treatment upregulates the expression of genes related to pluripotency and cell differentiation in the resulting embryos.

Summary: This study investigated the cytotoxicity and toxicological mechanisms of fluorochloridone (FLC) on cultured goat Sertoli cells. The results showed that FLC exposure induced oxidative stress, promoted apoptosis and autophagy, inhibited lysosomal biogenesis, and blocked autophagic flux in goat Sertoli cells. FLC also caused mitochondrial dysfunction and disturbed mitophagy, leading to cell apoptosis. The antioxidant N-acetyl-L-cysteine (NAC) reduced FLC-induced ROS accumulation and reversed the disorder of autophagy levels.

Summary: The study evaluated the effects of E2 treatment on Nelore heifers on day 15 of the estrous cycle, finding that E2 promoted an increase in PGFM concentrations and accelerated functional and structural luteolysis by upregulating the expression of PGR and OXTR. This suggests that within 3 hours after E2 stimulus, the expression of these receptors is associated with triggering luteolysis in cattle.
