Variação de peso no pós-parto de vacas F1 Holandês x Zebu de diferentes ordens de parto

Abstract

Utilizou-se do teste de regressao para estudar a variacao do peso apos o parto de vacas F1 Holandes x Gir, Holandes x Guzera, Holandes x Azebuado e Holandes x Nelore em nove ordens de partos. Os pesos utilizados foram o peso ao parto e a cada 28 dias ate o proximo parto. Os animais F1 Holandes x Zebu apresentaram diferentes comportamentos da variacao de peso entre as ordens de partos e grupos geneticos. Na primeira ordem de parto nao houve variacao de peso para os grupos geneticos Holandes x Guzera, Holandes x Azebuado e Holandes x Nelore, mas para o grupo genetico Holandes x Gir ocorreu reducao de peso na fase inicial e ganho a partir do meio ate o final da lactacao. Da segunda ate a setima ordem de parto, foram observadas variacoes no ganho de peso, de uma forma geral todas ganharam peso apos o parto. Ja na oitava e nona ordem todas as vacas, independente do grupo genetico mantiveram o peso apos o parto. Parte deste comportamento pode ser atribuido o nao ajuste da dieta a producao de leite destes genotipos, o que indica diferencas nas exigencias nutricionais dos animais F1 Holandes x Zebu em relacao aos animais especializados.
