This trial was conducted to study the effect of full-fat rice bran inclusion in diets on growth performance, carcass and meat quality and fatty acid composition in Sichuan goose. A total of 204 Sichuan white male geese (28-d-old, 984 ± 15 g) were used in the 42-d assay. Full-fat rice bran inclusion in diets was 0%, 6%, 12% and 18%, respectively. On d 70, two geese from each pen were randomly selected and killed for measuring the carcass and meat quality and the meat fatty acid composition. The results showed that full-fat rice bran inclusion had no effect on average daily gain during 28-56 d, but rice bran inclusion at 18% increased average daily gain during 57-70 d. In addition, the full-fat rice bran supplementation decreased the subcutaneous fat yield, and the inclusion of full-fat rice bran in amounts of 12% and 18% decreased the half-eviscerated carcass yield, eviscerated carcass yield and crude fat content in goose meat. Moreover, full-fat rice bran supplementation had no effect on the content of total saturated fatty acid (SFA), but decreased the content of total monounsaturated fatty acid (MUFA). The inclusion of full-fat rice bran in amounts of 12-18% increased the content of total polyunsaturated fatty acid (PUFA) and total n-6 in goose meat and in the amount of 18% increased n-3 fatty acids content in goose meat. The results indicated that the rice bran inclusion had a positive effect in geese by stimulating growth performance and improving meat quality and fatty acid composition of goose meat.
本试验旨在研究日粮中添加全脂米糠对四川白鹅生长性能、胴体及肉质和脂肪酸组成的影响。在为期42天的试验中,共使用了204只28日龄、体重984±15克的四川白鹅公鹅。日粮中全脂米糠的添加量分别为0%、6%、12%和18%。在第70天,从每个栏中随机选取两只鹅宰杀,测定胴体和肉质以及肉脂肪酸组成。结果表明,在28至56日龄期间,全脂米糠添加量对平均日增重无影响,但添加18%全脂米糠可提高57至70日龄期间的平均日增重。此外,添加全脂米糠可降低皮下脂肪产量,添加量为12%和18%时可降低鹅的半净膛率、全净膛率和鹅肉粗脂肪含量。而且,添加全脂米糠对总饱和脂肪酸(SFA)含量无影响,但可降低总单不饱和脂肪酸(MUFA)含量。添加量为12%至18%的全脂米糠可提高鹅肉中总多不饱和脂肪酸(PUFA)和总n-6含量,添加量为18%时可提高鹅肉中n-3脂肪酸含量。结果表明,添加米糠对鹅具有积极作用,可促进生长性能,改善鹅肉品质和脂肪酸组成。
