Summary
The aim of this study was to describe the growth of crossbred females of six genetic groups using the model of Brody. Genetic groups evaluated were: 50% Angus 50% Zebu (AZ), 50% BON 50% Zebu (BZ), 100% Zebu (Z), 50% Romosinuano 50% Zebu (RZ), 50%Senepol 25% Angus 25% Zebu (SAZ), and 50% Senepol 50%Zebu (SZ). The percent of maturity at 12, 18, and 24 months and ages at 75% and 95% of maturity was estimated. The maturity at 12 months varied between 42% and 48.5%, at 18 months between 53% and 60%, and at 24 months between 61% and 69%. The genetic group more precocious was AZ, and less precocious was BZ. The age at 75% of maturity varied between 1067 and 1468 days; and age at 95% of maturity varied between 2396 and 3322 days.
