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.

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.

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.

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.

Corn grain is an important ruminant energy source due its high starch levels. It is expected that whole corn can alter the amount of starch reaching the small intestine and, thus, positively influence the litter size (LS) via hormonal stimulation, compared with steam-flaked corn. Nutritional supplementation with whole corn and steam-flaked corn enhanced the lambing rate, live weight, and body condition scores but did not change the LS.

A total of 400 day-old quails were assigned to four treatments: control, 0 %, 0 .01 %, and 0.02 % ginger phyto-protease. Over 42 d, significant improvements in feed intake, body weight gain, feed conversion ratio, dressing percentage, villus height and width, and nutrient digestibility were observed, especially at 0.02 % enzyme inclusion. This suggests that 0.02 % ginger phyto-protease optimizes quail performance. 

This study examined genetic changes in body measurements at birth in Turkish Arabian foals born between 1987 and 2007. Significant factors influencing body size traits were identified. Additive genetic and maternal heritabilities varied, highlighting their impacts on foal traits. Results suggest the potential for selective breeding to enhance these traits over time, aiding future breeding strategies in Turkish Arabian horses.

Our study aimed to evaluate the effects of group size and the laying month on egg quality and the impact of group size on corticosterone and IgG levels in goose eggs in Hungary. From January to February, we demonstrated a decrease in egg width, shell thickness, shell weight, yolk weight, yolk ratio, yolk diameter, yolk colour with fan, and b* and an increase in albumen ratio and yolk pH. Regarding group size, the albumen pH, IgG, and corticosterone levels were higher in the small groups.

Our study sought to investigate the impact of incorporating guava agroindustrial waste (GAW) at varying concentrations on nutrient utilization, lamb performance and economic viability. These lambs were subjected to diets containing increasing levels of GAW (0, 7.5, 15, 22.5 and 30 % based on dry matter). Our findings suggest that GAW can be effectively integrated into sheep diets at levels of up to 30 % without compromising lamb performance. 

Cattle are monovular and naturally single-birth animals, producing only one calf per year. In this work, we evaluated the effect of inducing twin calves in beef heifers using different hormone treatment regimes. Animals were randomly selected for the procedure that induced double/triple ovulation via hormone treatment. This method may serve to promote twin production in beef cattle.
