Physical and chemical characteristics of milk from goats supplemented with different levels of total digestible nutrients in the dry period

ABSTRACT. We evaluated the physical and chemical characteristics of raw milk from goats supplemented with levels of Total Digestible Nutrients (TDN) in the dry period. Samples from 20 goats were divided into 4 groups, 3 groups received 400g concentrate per animal with different levels of TDN (65, 75 and 85%), and the control group (without concentrate). Four samples of milk were used for each animal, in four sampling periods, which were subjected to physical and chemical analysis. There was no significant difference between the treatments for the parameters of acidity and fat. The diet without concentrate presented higher value for the cryoscopic index. Mean values of the four treatments were within the range set by the Brazilian legislation for all parameters evaluated. The use of concentrate, containing 85% TDN in goat supplementation, was favored the physical and chemical characteristics of the milk during the dry period.
