To determine a possible relationship between protective maternal behavior and some reproductive variables in zebu cows, 30 cow-calf pairs were estrus synchronized at 25 days post-partum. No differences were observed in the number of cows displaying estrus or ovulating between those cows reacting to more calves with higher intensity, and the rest of the herd (P > 0.05). However, significant negative correlations were found between cows reacting to more calves and the presence of follicles (-0.39; P = 0.03), and cows displaying a more intense reaction toward their calf and estrous display (-0.46; P = 0.01). Current results suggest that protective maternal components might affect some reproductive variables.
