ABSTRACT
This paper contains a study of the effects of in-pasture dietary supplementation by different concentrates on the milk yield and quality of Bianca Monticellana, an indigenous goat breed reared in Italy. Two groups of lactating goats put out to pasture were fed poliphita hay; each group received one of two dietary concentrates during the first lactation stage. The administered concentrates contained similar energy (0.53-0.55 Milk FU) and protein (101.5-102.8 g). The average milk yield from morning-only milking in groups, 0.78-0.95 kg/head, was higher than the yield recorded during previous years in the same breed and lactation stage. The fat and protein content of the milk from the two groups were similar to those observed in animals of the same breed that produced lower milk yield. Comparison with values from cosmopolitan goat breeds indicates that this milk has an optimal ability to clot. In conclusion, the milk yield and quality of Bianca Monticellana can improve following administration of rations that appropriately address the dietary requirements. Moreover, the milk from these goats is suitable for cheese-making, a basic condition that brings a gratifying income to the farmer and consequently assures a greater population of indigenous breeds.
