Biometria do úbere de cabras anglonubianas / Anglonubian goat’s udder biometry

Abstract

A conformação do úbere dos caprinos possui relevância, uma vez que seu tamanho e forma estão associados à capacidade de produção de leite. Neste sentido, o objetivo do presente estudo foi determinar a relação entre as medidas da glândula mamária e a produção de leite em cabras da raça Anglonubiana. Em 15 cabras em lactação foram determinadas as medidas: circunferência e profundidade de úbere; a circunferência e comprimento de teto. As medidas foram realizadas antes (úbere cheio) e após a ordenha (úbere vazio). Ao final da ordenha matutina foi mensurada a produção de leite (em g). A produção de leite variou de 365 a 1.101,3 g de leite (média 856,21 g) na ordenha matutina. Observou-se grande variabilidade nas medidas de úbere antes e após a ordenha, sendo observada diferença significativa nas medidas médias da profundidade (p0,05) e circunferência de úbere (p0,001) e de teto (p0,05). Foi evidenciado um efeito linear crescente (R2=0,7559) e significativo (p0,001) do período de lactação sobre a produção diária de leite e a circunferência de úbere cheio. A biometria de úbere se torna significante nos resultados e, por ser um instrumento de fácil execução, é indicada como um dos parâmetros que o produtor pode utilizar no plantel sem demandar custo.
