Perfil de ácidos graxos no leite de vacas Holandês em pastagens tropicais suplementadas com dois níveis de concentrado.

Milk fatty acids profile was evaluated using 12 Holstein cows producing 15 kg/day of milk with 4.0% of fat. The animals were assigned to four treatments in a 2 x 2 factorial arrangement (two tropical grasses - Brachiaria brizantha cv. Xaraés and Panicum maximum cv. Tanzania, supplemented with two concentrate levels - 3 and 6 kg/cow/day) in a completely randomized block design. There was no effect of forage and concentrate level (P>0.05) on concentrations of rumenic, vaccenic, (C18: 1 trans-11) and oleic acids in milk fat (mean values of 1.01, 1.79, and 22.55 g/100 g of total fatty acids, respectively). The concentrations of lauric (C12:0), myristic (C14:0), and palmitic (C16:0) acids were also unaffected by treatments (mean values of 2.63, 9.77, and 27.44g/100g of total fatty acids, respectively). Overall, the results illustrate the potential of tropical grasses in producing milk containing a more desirable fatty acids profile in terms of human health.
