【摘要】：本试验旨在研究饲粮补充鲜桑叶对肉兔生产性能和肉质的影响。试验选择30日龄断奶的新西兰肉兔144只,随机分成4个处理,每个处理6个重复,每个重复6只。对照组饲喂配合饲料,试验组分别饲喂"鲜桑叶+精料补充料"、"鲜桑叶+60%配合饲料"和"鲜桑叶+80%配合饲料"试验期为49 d。结果显示:肉兔饲喂"鲜桑叶+精料补充料"可以显著提高日增重(P0.05),饲喂"鲜桑叶+配合饲料"随着配合饲料比例的减少,日增重和成活率显著下降(P0.05);肉兔饲喂"鲜桑叶+精料补充料"可以显著提高屠宰率(P0.05),饲喂"鲜桑叶+配合饲料"随着配合饲料比例的减少,屠宰率显著下降(P0.05);肉兔饲喂鲜桑叶对兔肉水分和粗蛋白质无显著影响(P0.05),可以显著提高兔肉中肌苷酸含量(P0.05),鲜桑叶饲喂量越多,兔肉肌苷酸含量越高;饲喂鲜桑叶对24 h肉色、p H 45 min、45 min b*和45 min L*无显著影响(P0.05),可显著提高肉色45 min a*和p H24 h值(P0.05),显著降低滴水损失(P0.05),其中饲喂"鲜桑叶+精料补充料"组肉品质最佳。结果表明,肉兔饲喂"鲜桑叶+精料补充料"可以显著提高日增重,增加兔肉风味物质,提高兔肉品质。
[Abstract]:The purpose of this experiment was to study the effect of fresh mulberry leaf supplementation on the performance and meat quality of meat rabbits. 144 New Zealand meat rabbits weaned at 30 days old were randomly divided into 4 treatments with 6 replicates each. The control group was fed with compound feed, The experimental period of "fresh mulberry leaf concentrate supplement", "fresh mulberry leaf 60% formula feed" and "fresh mulberry leaf 80% formula feed" was 49 days. The results showed that "fresh mulberry leaf concentrate supplement" could be significantly increased by feeding the meat rabbit with "fresh mulberry leaf concentrate supplement". Increasing daily weight gain (P0.05), feeding "fresh mulberry leaf feed" with the decrease of the proportion of formulated feed, The daily gain and survival rate decreased significantly (P 0.05), the meat rabbits were fed with "fresh mulberry leaf concentrate supplement", the slaughter rate was significantly increased, and "fresh mulberry leaf feed" decreased with the decrease of the proportion of mixed feed. Slaughtering rate decreased significantly (P 0.05), fresh mulberry leaves had no significant effect on water content and crude protein of rabbit meat, and the content of inosine in rabbit meat was significantly increased. The more fresh mulberry leaves were fed, the higher the content of inosine in rabbit meat was. Fresh mulberry leaves fed with fresh mulberry leaves had no significant effect on 24 h meat color, 45 min b * and 45 min L *, but could significantly increase meat color 45 min a * and pH 24 h value (P0.05), and significantly reduce drip loss (P 0.05). Among them, the meat quality of fresh mulberry leaf concentrate supplement group was significantly reduced. The results show that. "fresh mulberry leaf concentrate supplement" could significantly increase the daily gain, increase the flavor of rabbit meat and improve the quality of rabbit meat.
