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 regarding calving in the Polled Gir cows were studied from 1973 to 1976. It was observed that the highest number of births occurred from July to October, with the peak in August. Birth distribution, as well as impregnations during this period, showed results similar to those cited by CARNEIRO and Cols.,  TABARELLI NETO et alii., JOCHLE, HUDDER and McCAMLEY, and GUSMÃO. The lowest birth rate occurred during the months of November and December 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 female calves was statistically significant only in 1974. The results of 192 items observed showed that the medium interval between births was 16.82 +/- 4.82 months.

O objetivo deste trabalho foi identificar o comportamento reprodutivo de um rebanho Gir Mocho criado a campo, em regime de cobertura natural, pertencente à Fazenda Tapete Verde, Município de Carmo do Rio Verde, Estado de Goiás. O trabalho mostra o estudo de 488 dados de partos em vacas Gir Mocho, no período de 1973 a 1976. Observou-se que o maior número de nascimento ocorreu de julho a outubro com o pico máximo em agosto. A distribuição dos nascimentos, bem como das fecundações neste período, assemelham-se aos resultados obtidos por CARNEIRO e Cols., TABARELLI NETO et alii, JOCHLE, HUDDER e McCAMLEY e GUSMÃO. O menor número de nascimento ocorreu nos meses de novembro e dezembro e deveu-se à retirada dos touros nos meses de janeiro e fevereiro. Observou-se uma maior proporção de machos, também, nos anos de 1973 a 1976, porém, esta proporção foi estatisticamente significativa apenas em 1974. Os resultados de 192 observações mostraram que a duração média do intervalo entre partos foi de 16,82 +/- 4,82 meses.Escola de Agronomia - Universidade Federal de Goiás2007-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/x-forcedownloadhttps://revistas.ufg.br/pat/article/view/2326Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 8, n. 1, Jan./Dec. 1978; 161-172Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 8, n. 1, jan./dez. 1978; 161-172Pesquisa Agropecuária Tropical; v. 8, n. 1, jan./dez. 1978; 161-1721983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2326/2283Ferreira, Paulo Roberto CostaDias, José CésarNunes, Romão da Cunhainfo:eu-repo/semantics/openAccess2020-02-26T23:49:43Zoai:ojs.revistas.ufg.br:article/2326Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:03.828467Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
