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.

In the production of chicken, phytobiotics have the potential to replace antibiotics. This experiment was carried out to investigate the impact of phytogenic feed additives (NUQO©NEX) as a natural growth promoter on growth parameters and economic efficiency measurements. Broiler chickens fed a diet supplemented with NUQO©NEX showed positive effects on the overall performance, cholesterol, antioxidant status and immune state, carcass quality traits, and economic effectiveness measurements.

This study investigated the extent to which genetic factors contribute to variations in body weight among Anatolian buffalo calves from birth to 12 months of age. Utilizing data collected from multiple farms in the Istanbul region, the analysis revealed that genetic influence on growth traits is substantial. The results indicate that selection based on estimated genetic merit could effectively enhance growth performance in Anatolian buffalo populations.

In this study, we integrated short-read and long-read sequencing techniques to reveal transcriptional regulation characteristics of deleted in azoospermia-associated protein 2 in pigs. Notably, we identified two distinct transcripts of this gene. Specifically, its expression was most prominent in the urethral bulb glands and testes. These findings lay a foundation for further investigation into the role of this gene in sperm capacitation in pigs.

This study explores the potential of using cull ewe meat to enhance the value of traditional sheep meat products, focusing on the Tunisian dried meat "kaddid". Two local sheep breeds, i.e. Noire de Thibar (NT) and Barbarine (BR), were evaluated at two slaughter ages (3 months and 5 years). Results showed that BR raw meat had more antioxidants (α-tocopherols) and healthy fats; however, kaddid from NT ewes had higher tocopherol levels, with favourable polyunsaturated fatty acid (PUFA) profiles. 

Anti-Müllerian hormone (AMH) serves as a reliable marker for ovarian reserve and reproductive potential in many species. However, there is limited information available on the factors influencing AMH levels in sheep. This study demonstrates that sheep breed is a significant determinant of serum AMH concentrations, reflecting differences in ovarian reserve among breeds. Thus, these findings provide valuable insights for genetic variation, selection programs, and fertility management.

The Large White (LW) pig is a valuable breed in the pig industry, known for its growth efficiency and reproductive performance. We identified a fragment of the Danish LW runs of homozygosity (ROH). We then calculated inbreeding coefficients and screened candidate genes from the ROH archipelago for economically important traits. Our results provide useful insights into the function of ROH on a genetic basis and their role in controlling superior traits in Danish LW pigs.
