摘要：

Thirty six male goats grazing Caatinga native pasture were randomly assigned to 4 concentrate supplementation levels (0, 5, 10 and 15 g/kg of body weight) and slaughtered after 120 days. Longissimus muscle meat lipids were extracted and fractionated into neutral (NL) and polar (PL) lipids. Supplementation of grazing goats increased linearly (P < 0.05) intramuscular fat (1 to 1.5% of meat) and NL (0.3 to 1% of meat) but decreased linearly (P = 0.044) the PL (0.66 to 0.50% of meat). On NL, supplementation increased linearly (P = 0.047) the proportion of c9-18:1 (31 to 40% of FA) with supplementation. On PL, supplementation reduced linearly (P < 0.03) the dimethyl acetals, 18:3n-3 and most of long chain polyunsaturated FA (PUFA) proportions but increased linearly (P < 0.001) the c9-18:1. Considering the total meat FA, supplementation led to an increase of the saturated and monounsaturated FA contents and a decrease of the long chain n-6 and n-3 PUFA contents.
