Abstract

The study was made with data from the zootechnical record of Fazenda Guará, which is situated in Guzolândia in the northwestern region of São Paulo State. Ten year data were computed, from 1968-1977, commencing with the initial birth of 381 hybrid calves (5/8 charolês-zebu) and 1/2 canchim. The first generation of this herd was on the average chekted at 1,015 ± 4.6 days (33.8 ± 0.15 months), with a coeficient of variation of 10.1%. The normal curve adjusted to the histogram whose X2 test was not significant, demonstrating that this curve represents the age distribution of the first generation.
