Abstract

The objective of this study was to investigate the effects of dietary supplementation of SCD inhibitor (sycamore seed oil) and accelerator (rosiglitazone) on production performance, serum hormone and biochemical indexes relevant to lipid metabolism of fattening sheep. Eighteen crossbreed ram (Merino sheep ♂×thin-tail Han sheep♀), similar in body weight[(27.71±2.64) kg] and body condition, were randomly divided into 3 groups with 6 sheep per group. Sheep in control group (C group) were fed a basal diet +4.8% linseeds; those in sycamore seed oil group (W group) were fed the diet in C group supplemented with 15 g/d sycamore seed oil; those in rosiglitazone group (L group) were fed the diet in C group supplemented with 8 mg/d rosiglitazone. The trial period lasted for 50 d consisting 10 d of transition period, 5 d of pre-trial period and 35 d of trial period. The results showed as follows:1) about production performance, the addition of sycamore seed oil and rosiglitazone in diets had no significant effects on production performance, slaughter performance and meat productivity (P>0.05); about adipose deposition, backfat thickness in W group was significantly higher than that in C group and L group by 12.55% and 17.23%, respectively (P<0.05). 2) About serum hormone indexes, serum contents of growth hormone (GH), glucagon (GC) and leptin (LEP) in W group were significantly higher than those in C group (P<0.05), and serum GC content in L group was significantly higher bthan that in C group(P<0.05). 3) About serum biochemical indexes, compared with C group, serum contents of high density lipoprotein cholesferol (HDL-C), low density lipoprotein cholesferol (LDL-C), total cholesterol (TC) and triglyceride (TG) were significantly increased in W group (P<0.05), but only serum TG content was significantly increased in L group (P<0.05). In conclusion, the addition of sycamore seed oil and rosiglitazone in diets had no significant effects on production performance, slaughter performance and meat productivity of sheep, but sycamore seed oil can significantly increase backfat thickness of sheep; the addition of sycamore seed oil in diet increases serum contents of GH, GC and LEP of sheep, and rosiglitazone can increases serum content of GC of sheep; serum contents of HDL-C, LDL-C, TC and TG of sheep in W group are significantly increased, and only serum TG content in L group is significantly increased.
