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. 

Bovine mastitis, a costly inflammation caused mainly by pathogenic bacteria, harms milk yield and the economy worldwide. This review covers its clinical forms, diagnostics, the immune role of melatonin, and alternatives to antibiotics (such as herd management and bacteriophages). It highlights research gaps in genetics and microbiomes, urging integrated, sustainable control strategies.

This study explores the genetic diversity of the Balkan goat. We analyzed specific parts of the genetic material in goats to understand how diverse and related they are. Results showed high genetic diversity and low levels of inbreeding. Analysis of maternal genetic lines in 16 animals revealed 12 different lineages belonging to haplogroup A.

The endangered Angler Saddleback pig is a fatty breed and has been fed high-fiber diets for decades. In view of this, a fatty acid composition different from that of commercial breeds was identified. In addition, the fatty acid composition in intramuscular fat and back fat was less correlated, suggesting a genetic effect in addition to dietary factors. Significant loci identified in genome-wide association studies underline the potential importance of this breed.

The study examined the effect of the human handling of newborn calves on their development and immune system efficiency. Holstein-Friesian calves in one group were licked after birth by the mother, whereas the other group were handled by a human. Daily gains were controlled, and blood was collected for protein fractions and complete blood count analysis. The replacement of natural maternal care (licking) of a newborn calf by a human did not adversely affect the development and health of the calf.

Microalgae have been explored as protein supplements for dairy cows, but results vary. This study assessed their effects using meta-analysis, considering factors like species, inclusion level, and breed. Microalgae reduced dry matter intake but improved fiber digestibility. Milk fat decreased, yet C18:2 c9t11 and C22:6 n-3 increased. Schizochytrium sp. boosted C22:6 n-3, and Holstein–Friesian cows reduced saturated fatty acids, supporting microalgae as a sustainable feed supplement.

This study examined the relationship between genetic differences in the growth hormone gene and growth and placental characteristics in Tuj sheep. Those with a particular gene polymorphism revealed superior growth post-birth and a more efficient placental structure. These results imply that genetic testing could be used to identify animals with greater growth potential at an early stage, thus facilitating more effective and sustainable breeding decisions.
