This research studied what affects the number and health of piglets in large-scale farms. It found that the year, the mother sow's age, and her weight at birth are major factors. Moving piglets between litters after birth (cross-fostering) also helps them grow better. While genetics play a role, good management practices are even more important. The best results come from combining careful genetic selection with excellent daily care, proper feeding, and a controlled environment for the animals.

The ability of spermatozoa to penetrate the egg and their competitiveness in the female reproductive organs may depend on their dimensions and shape, and these are often related to the characteristics of the ejaculate.  It has been shown that, as sperm concentration in the ejaculate increases, the dimensions of spermatozoa heads and tails decrease. Sperm concentration also affects the shape of Arctic fox spermatozoa.

This study is the first to measure a natural sperm protection protein at both gene and protein levels in Donggala bulls, an Indonesian cattle breed not previously studied this way. We found that higher levels of this protein are linked to better sperm movement, healthier cell membranes, and less damage after freezing and thawing. This protein can help identify stronger bulls for breeding and support improved cattle reproduction and conservation.

This study investigated the effect of organic and inorganic chromium supplementation on growth and nutrient digestibility in chickens raised under chronic heat stress. The results show that 400 ppb organic chromium and 100 ppb inorganic chromium improve growth and protein digestibility. The use of organic chromium has demonstrated greater effectiveness, suggesting that it could be a useful strategy for nutritional management under adverse climatic conditions.

This study examined the effects of subclinical pregnancy toxemia (SPT) on follicular development and evaluated the protective potential of L-carnitine supplementation in ewes. İn this study, our results highlight the importance of adequate nutrition and metabolic support during late gestation, suggesting that L-carnitine supplementation may enhance follicular growth and reproductive performance in ewes with SPT.

Optimizing grazing animal feeding improves livestock efficiency and reduces environmental impacts. Monensin use raises concerns about resistant bacteria and public health. Replacing monensin with capsaicin showed no differences in intake, digestibility, blood parameters, or ruminal fermentation. This suggests that strategic supplementation can enhance productivity and sustainability in livestock farming.

This study examined how pregnancy type, genotype, and parturition stage affect sheep behavior and labor traits. Twin pregnancies resulted in longer labor and different behavioral patterns compared to singletons, while genotype showed minimal impact. Lying and standing frequency of ewes during the first two stages of parturition was a useful indicator of pregnancy type and labor timing. The results highlight the importance of customized management strategies to improve ewe welfare and lamb survival rates.

This study investigated the impact of continuous heat stress and nighttime recovery on the yield of oocytes and the production of embryos in Holstein heifers. Oocyte collection sessions in the same herd under identical care and feeding were categorized using the day’s peak and average heat–humidity load. It was observed that nighttime recovery had a positive effect on oocyte and blastocyst yield. This suggests that nighttime temperatures should be considered when evaluating heat stress.
