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.

Arch. Anim. Breed., 69, 37–44, https://doi.org/10.5194/aab-69-37-2026, 2026
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.
