摘要：

Aim of the study was to evaluate the effect of different proportions of hay and fresh grass in goats diet on milk fatty acid profile. Nine Camosciata goats were fed a fixed amount of concentrate (30% of total diet) and different percentages (40% vs 30%, 50% vs 20% and 60% vs 10%) of hay and fresh grass, respectively. Diminishing amounts of fresh grass percentages in the diet led to significant increases of lauric, myristic and palmitic acids (P = 0.001) and to significant decreases of C18:1 t6-11, rumenic and a-linolenic acids (P = 0.001) in milk, thus determining a worsening of the health value of milk fat.
