摘要
Foram utilizados 12 animais da ra a Saanen, com peso vivo de 35 kg e produ o leiteira de 1,2 kg, para avalia o da suplementa o lip赤dica sobre o consumo, digestibilidade, produ o e composi o do leite e quatro animais fistulados no r迆men para observa o do pH. Os tratamentos consistiram de uma dieta-controle e tr那s dietas suplementadas com semente de faveleira, torta de faveleira e caro o de algod o. Os dados foram analisados em quadrados latinos 4 x 4, com tr那s repeti es e as an芍lises estat赤sticas feitas pelo teste de Tukey a 5% de probabilidade. A suplementa o lip赤dica diminuiu o consumo de mat谷ria seca e da maioria dos nutrientes, com reflexo sobre a produ o e composi o do leite de cabras Saanen. A suplementa o com torta de faveleira e com caro o de algod o pode ser considerada uma boa alternativa alimentar para cabras Saanen. This study used 12 Saanen goats with BW of 35 kg and daily milkproduction of 1.2 kg, in order to evaluate the effect of fat supplementation on the intake, digestibility and milk yield. Four animals were fistulated in the rumen for pH observation. The treatments consisted of a control diet and three diets supplemented with faveleira seed, faveleira cake and cotton seed. The data were analyzed in 4 x 4 chi squares, with three repetitions and the statistical analyses by Tukey%26apos;s test at 5% probability. Fat supplementation decreases the intake of dry matter and of most nutrients, affecting milk yield and the composition of Saanen goat milk. Supplementation with faveleira cake and cotton seeds can be considered as an alternative feed for those animals.
