【摘要】：研究旨在探讨日粮添加菊苣对扬州鹅生长、物质转化、肉品质、肌肉氨基酸和脂肪酸组成的影响。结果显示:日粮中添加菊苣饲养至第5周后鹅体重显著高于对照组(P0.05);日粮中添加菊苣降低了鹅对整个摄入物质的利用率,平均为74.57%,比对照组降低了1.02%;处理组和对照组物质同化效率均呈现逐渐下降的趋势;日粮中添加菊苣一定程度上促进了鹅对精饲料的摄入和转化;日粮中添加菊苣降低了胸肌和腿肌中水分、蛋白质、脂肪、肌苷酸、系水力和p H值等指标,增加了胸肌和腿肌肉色指标,胸肌和腿肌嫩度指标变化趋势相反;日粮中添加菊苣对胸肌和腿肌的氨基酸组成影响很小;日粮中添加菊苣可以提高胸肌和腿肌中饱和脂肪酸和多不饱和脂肪酸含量,降低单不饱和脂肪酸含量,胸肌和腿肌中亚麻酸含量均是处理组显著高于对照组(P0.05),其中在胸肌的提高幅度较大。
[Abstract]:The purpose of this study was to investigate the effects of chicory supplementation on growth, substance transformation, meat quality, muscle amino acid and fatty acid composition of Yangzhou Goose. The results showed that the body weight of geese fed with chicory was significantly higher than that of the control group (P0.05), and the utilization rate of the whole intake of the geese was decreased by adding chicory to the diet. The average value was 74.57, which was 1.02% lower than that of the control group. The assimilation efficiency of both the treatment group and the control group showed a decreasing trend, and the addition of chicory to the diet promoted the intake and transformation of concentrate feed to some extent. Addition of chicory to diet decreased the indexes of water, protein, fat, inosine acid, hydraulic capacity and pH value of pectoralis muscle and leg muscle, increased the color index of pectoralis muscle and leg muscle, and the tenderness index of pectoralis muscle and leg muscle showed the opposite trend. Addition of chicory to diet had little effect on amino acid composition of pectoralis muscle and leg muscle, supplementation of chicory could increase the content of saturated fatty acid and polyunsaturated fatty acid in pectoralis muscle and leg muscle, and decrease the content of monounsaturated fatty acid. The contents of linolenic acid in pectoralis and leg muscles were significantly higher in the treatment group than in the control group (P0.05).
