Resumo

The objective of this work was to estimate the age and live weight at the first breeding in the Nelore (N), Pantaneira (P), and crossbreeding Pantaneira x Nelore (PxN) heifers. A total of 98 females was used for treatments, 51, 24 and 23 from N, P and PxN heifers, respectively. The statistical analysis did not show any significant difference (P = 0.3595) to live weight in the first breeding among breeds. The variance analysis did not show any significant difference (P = 0.307) of age among breeds, showing 3.5, 3.4 and 3.2 years to P, N and ½PxN heifers, respectively.
