The cow's perineal muscle is connected to the rectum, vulva, and vagina. The author hypothesizes that changes in reproductive status affect perineal muscle tension, which will affect the anatomy of the coccygeus and levator ani muscles. The sonograms we obtained showed a significant increase in the coccygeus and levator ani muscles of pyometra cows compared to endometritis, nonpartum pregnant, pregnant, and postpartum pregnant cows.

A ban on the sub-therapeutic use of antibiotics as growth promoters has prompted the development of alternatives to accomplish the same goals. This paper deals with the dietary supplementation of two different phytogenic blends in broiler chickens. The study showed that phytogenic blends based on Ginkgo biloba and Silybum marianum improved the growth performance and intestinal immunity, revealed by immunohistochemistry and quantitative real-time polymerase chain reaction.

Cryopreservation of semen faces challenges due to oxidative stress. Researchers found that adding resveratrol (RSV) at 10-40 μmol L^-1 to Mongolian horse semen improved sperm quality, with best results at 40 μmol L^-1. Proteomic analysis showed increased antioxidant proteins. Further tests confirmed RSV's potential as an effective antioxidant for enhancing semen cryopreservation, offering promise for overcoming these challenges.

This study evaluated the impacts of selenium nanoparticles (SeNPs), zinc oxide nanoparticles (ZnONPs), and a combination of SeNPs and chromium (Cr) or ZnONPs and Cr on growth, caecal microbiota, antioxidant capacity in blood and liver tissue, and inflammatory cytokines in heat-stressed rabbits. SeNPs or ZnONPs with chromium can be recommended as an effective intervention to mitigate the negative impacts of heat stress by enhancing growth and immunity and promoting metabolic processes.
