Efeito do intervalo de partos sobre a eficiência produtiva e econômica em rebanhos gir leiteiro

Abstract

Foram analisados 13.406 registros de lactação de 7.153 vacas Gir Leiteiro com partos ocorridos de 1960 a 2008 com o objetivo de estimar ganhos ou perdas econômicas e em produção de leite atribuídos à variação no intervalo de partos (IP). Foi observada produção de leite média por vaca por lactação de 2.846,95 ± 1.339,72 kg e média de IP de 449,86 ± 51,54 dias. A redução do IP observado para 365 dias levaria a aumento na produção de leite de 558,16 kg. Os resultados econômicos decorrentes das perdas nas produções de leite e de bezerros foram de R$ 467,34/vaca/lactação. Os gastos com ração e mão de obra foram de R$ 198,22. A perda econômica total foi de R$ 269,12/vaca/lactação. O aumento no IP tem resultado em perdas produtivas e econômicas nos rebanhos estudados.
