日粮中添加柚皮粉对五华三黄鸡生产性能和肉品质的影响

摘要

To investigate the feeding effect of grapefruit peel power,60 one-day-old Wuhua Three-yellow chickens were divided into 2 groups of 30 each. They were fed with 0% and 5% grapefruit peel power ex-tra for 150 days. The growth,slaughter performance and muscle nutrition of chickens were measured after 150 days,and the feed consumption,weight and body measurement were investigated every week. The re-sults showed that grapefruit peel power had no effect on the growth and slaughter performance of chic-kens. Grapefruit peel power could significantly increased the protein content by 12. 84%(P<0. 01),and increased the meat redness,color and OD data(23. 53%,P<0. 01). Meanwhile,the fat content declined significantly by 46. 99%(P<0. 01). However,the water-holding capacity of meat also declined signifi-cantly by 15. 94%(P<0. 01),and the rate of water loss increased by 55. 22%(P<0. 01). Therefore, the adding level of grapefruit peel power extra at 5% could improve the protein content and meat quality, reduce the fat content of the muscle in Wuhua Three-yellow chickens.%为探讨柚皮粉的饲喂效果,将60只1日龄五华三黄雏鸡随机分成对照组和试验组2组,每组30只。对照组饲喂基础日粮,试验组在基础日粮中添加5%的柚皮粉,连续饲养150 d,研究柚皮粉对1~150日龄五华三黄鸡生长发育、屠宰性能及肉品质的影响。每周测定耗料量、体质量及体尺性状指标,在第151天测定屠宰性能及肉品质。结果表明：与对照组相比,饲料中添加柚皮粉对雏鸡的生长发育和屠宰性能没有明显影响,添加柚皮粉能使肌肉的蛋白质含量提高12.84%(P<0.01),提高肌肉的红度、改善肉色,OD值提高23.53%(P<0.01),使肌肉的脂肪含量降低46.99%(P<0.01),肌肉系水力降低15.94%(P<0.01),失水率提高55.22%(P<0.01)。综上所述,日粮中添加5%的柚皮粉能显著提高五华三黄鸡的肌肉粗蛋白含量、降低脂肪含量,在改善肉质方面起到一定作用。
