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.

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 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.

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 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.

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 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 overall success rate based on the insemination results of all the sheep was determined to be 82.77%. In an examination of the pregnancy rate, one of the indicators of reproductive performance, the difference between the groups is statistically significant (p≤0.05). Higher pregnancies were obtained in insemination with semen fluid containing oxytocin.

This study reports long-term data collected over 10 years on the reproduction, growth, carcass yield, chemical composition, and sensory quality of meat from three native sheep breeds raised under extensive conditions in eastern Türkiye. By combining farm records with laboratory and sensory analyses, clear breed-specific differences were revealed. The results provide a strong scientific basis for sustainable, breed-oriented sheep production and meat quality improvement.

This study was carried out to compare conventional hatchery-hatching and on-farm-hatching systems in terms of hatching success and first-week chick performance for different broiler genotypes. There were no significant differences in the hatchability of fertile eggs and total embryonic mortality between the hatching or genotype groups. Hatching time was significantly influenced by the hatching system and genotype.
