Short summary
Weaning is a stressful event and is a critical period that affects probably the reproductive development of lambs. The objective of the study was to evaluate the effect of the weaning method on sexual behavior and semen quality of 3-month-old lambs. It was found that the lambs that were completely separated from their mothers presented lower levels of stress and developed better, but they were not better in terms of sexual behavior and seminal quality.
