Resumo: | Infection due to the gastrointestinal nematodes can negatively interact with the productive performance of dairy goats, and in some cases can induce mortality in the flocks. The objective was to study the influence of season, parturition order, postpartum, lactation and breed standard on the population of helminths in dairy goats. 31 goats were used, with 15 Saanen and 16 F1 (½ Boer + ½ Saanen). Of these, 13 were from the 1st lactation and 18 from the 2nd or more lactations. The highest fecal egg counts occurred during the summer and spring, with FEC in Saanen higher (p < 0.01) than in F1 animals (½ Boer + ½ Saanen). The animals with 1st lactation showed higher FEC (p < 0.004) than the animals in 2nd or more lactation. During the peripartum the largest FEC for both breeds standards were in the week of the birth (p < 0.05), followed by post-partum and pre-partum. In peripartum the Saanen goats showed higher FEC (p < 0.02) than the F1 and primiparous (p < 0.008) in relation to pluriparous. F1 animals are resistant to helminthes when compared to Saanen animals, demonstrating that crossing of resistant breeds with high production breeds is a viable alternative to increase productivity without compromising the parasitary stability of the herd. The peripartum period is a risk factor associated to the occurrence of gastrointestinal helminths, especially in Saanen goats from first lactation. |

Infecção por nematóides gastrointestinais pode interagir negativamente com a performace produtiva de cabras de leite, e em alguns casos induzir a mortalidade em rebanhos. Objetivou-se conhecer a influência da estação do ano, ordem de parto, periparto, lactação e padrão racial sobre a população de helmintos em cabras leiteiras. Foram utilizadas 31 cabras, sendo 15 Saanen e 16 F1 (½ Saanen + ½ Bôer). Destas, 13 eram de 1º lactação e 18 de 2º ou mais lactações. As maiores contagens de OPG ocorreram no verão e primavera, sendo o OPG dos animais Saanen superior (p < 0,01) ao dos F1 (½ Saanen + ½ Bôer). Os animais de 1º lactação apresentaram OPG superior (p < 0,004) ao dos animais de 2º ou mais lactação. Durante o periparto as maiores contagem de OPG para os dois padrões raciais foram na semana do parto (p < 0,05), seguida pelo pós-parto e pré-parto. No periparto as cabras Saanen apresentaram OPG superior (p < 0,02) aos F1 e as primíparas (p < 0,008) em relação as pluríparas. Animais F1 são resistentes a helmintos quando comparado a animais Saanen, demonstrando que o cruzamento de raças resistentes com raças de alta produção é uma alternativa viável para aumentar a produtividade sem comprometer a estabilidade parasitaria do rebanho. O periparto constitui fator de risco associado á ocorrência de helmintos gastrintestinais, especialmente em cabras Saanen de primeira lactação.
