摘要: This study investigated the fatty acid composition and mRNA levels of acetyl-coenzyme A carboxylase (ACC), synthase (FAS), hormone-sensitive lipase (HSL) lipoprotein (LPL) genes in Longissimus dorsi muscle (LD) Biceps femoris (BF) nine ovariectomised young goats, 50 days after ovariectomy at 5 months age, relative to Control goats. Ovariectomy resulted faster growth rates (130 vs 110 g/days; P = 0.027), more intramuscular fat (3.37% 1.62%; 0.009) heavier final weights (28.3 26.6 kg; 0.035). The total saturated acid, C15:0 LD C6:0, C11:0, C12:0, C21:0 BF were lower goats than that (P < 0.05). increased monounsaturated acids 0.05) 0.01). In BF, polyunsaturated C18:2 those 0.05), C20:2 content significantly decreased expressed higher FAS but HSL Significantly ACC, LPL observed Controls These data suggest affects potentially by altering expression lipid-metabolic muscles
