Resumo
The objective of this study was to identify
the reproductive behavior of a herd of Polled Gir Cattle put in open pasture, at the Tapete Verde Ranch in Carmo do Rio Verde county in the state of Goiás.
Four hundred and eighty-eight (488) items r! garding calving in the Polled Gir cows were studied from 1973 to 1976.
It was observed that the highest number of bi.!
ths ocurred from July to October, with tbe peak in lrugust.
Birth distribuition, as well as impregnations during this period, showed result similar to those cited by CARNEIRO e Cole., TABARELLI NETO e Cols,, JOCHLE, HUDDER e McCAM.LEY and GUSMÃO.
The lowest birth rate ocurred during the mo ths of Novernber and Decernber because the bulls were removed from the herd in the months of January.
A large percentage of male calves was born in all three years, although the proportion in relation to fem! le calves was statistically significante only in 1974,
The results of 192 items observed showed that
the medium interval bettween births was 16,82 ! 4,82 months.
