- Abstract
The experiment was to investigate the effect of linseed oil and palm oil supplementation on serum biochemical indices, lipid metabolism-related enzyme activities and apparent digestibility of nutrients of cashmere goats. 12 healthy cashmere goats with similar age were randomly divided into linseed oil group (LO group), palm oil group (PO group) and mixed oil group (MO group, the ratio of linseed oil to palm oil was 6∶4). The ratio of concentrate to forage was 5∶5, and the amount of oil was 2% of the whole diet. The pre-test was 7 d, and the formal test period was 23 d. The result showed that compared with PO group, serum triglyceride, cholesterol and low density lipoprotein concentrations of cashmere goats in LO group and MO group were significantly decreased, high density lipoprotein concentrations were significantly increased (P<0.05). The activities of hormone-sensitive lipase and lipoprotein lipase in serum of cashmere goats in PO group and MO group were significantly lower than those in LO group (P<0.05). The elongase activity of ultra-long chain fatty acids in serum of cashmere goats in PO group was significantly lower than that in MO group and LO group (P<0.05), the activities of ∆-5 fatty acid dehydrogenase, acetyl-CoA carboxylase and pyruvate dehydrogenase kinase 4 in serum of cashmere goats in LO group and PO group were significantly lower than those in MO group (P<0.05). The digestibility of neutral detergent fiber and acid detergent fiber in MO group was significantly higher than that in LO group (P<0.05). The experiment indicates that diet using a mixture of 6∶4 can promote down producing goat linseed oil and palm oil fatty acid generated from scratch, n-3 PUFA related enzyme activity, improve the efficiency of the protein utilization in down producing goat, reduce blood fat deposition, has better effect than that of adding a single linseed oil and palm oil, relieve added individually linseed oil caused by fiber digestion rate of decline.
