复合胶原蛋白粉对肉仔鸡生长性能及肉品质的影响

选用1日龄艾维茵肉仔鸡180只,随机分为3组,对照组,饲喂不含复合胶原蛋白粉的日粮,试验1用复合胶原蛋白粉替代日粮中一半豆粕,试验2用复合胶原蛋白粉替代日粮中全部豆粕。分析测定试验的生长发育指标屠宰指标及肉质指标结果,与对照组相比一半替代组,肉仔鸡末重、日增重、日采食量分别提高15.74%（P〈0.01）、2.59%（P〉0.05）、13.90%（P〈0.01）,全部替代组三指标有所降低,但差异不显著（P〉0.05）;实验组屠宰率、全净膛率、胸肌率、腿肌率均以一半替代组为最高;腹脂率以一半替代组为最低其它指标差异不显著;各试验组胸肌及腿肌差异均不显著（P〉0.05）;除全部替代组胸肌中蛋白含量比对照组相提高了4.24%（P〈0.05）除外,其它各指标在各组间均无显著差异（P〉0.05）。表明用复合胶原蛋白粉替代肉仔鸡日粮中一半豆粕可以提高科技转化率和生长性能。

Effect of Compound Collagen Powder on Productive Perfor mance and Meat Quality of Broilers

180 one-day age Avian broilers were selected and randomly divided into 3 groups.The control group was fed basal diet without compound collagen powder;the experimental group 1 was fed the diet in which compound collagen powder substitute half soybean meal;the experimental group 2 was fed the diet with total compound collagen powder.The growth performance,slaughter performance and meat qualities were measured.Compared with the control group,the final weight,daily weight gain,daily intake of group 1 respective...
