Abstract
Objective. To characterize growth curves and reproductive performance of Romosinuano cows in Mexico. Materials and methods. Weight and age records (928) of females (117) for growth traits and calving records (459) of cows (113) for reproductive traits were analyzed. Four non-linear mixed models were adjusted to describe the growth curves. Indicators of age at 50% of maturity
