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(P<0.05),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(P<0.05);肉兔饲喂“鲜桑叶+精料补充料”可以显著提高屠宰率(P<0.05),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(P<0.05);肉兔饲喂鲜桑叶对兔肉水分和粗蛋白质无显著影响(P>0.05),可以显著提高兔肉中肌苷酸含量(P<0.05),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(P>0.05),可显著提高肉色45 min a*和p H24 h值(P<0.05),显著降低滴水损失(P<0.05),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。
The purpose of this study was to investigate the effect of dietary supplementation of fresh mulberry leaves on the performance and meat quality of meat rabbits. A total of 144 New Zealand white rabbits aged 30 days were weighed and randomly divided into 4 treatments with 6 replicates each for 6 replicates. The control group was fed with compound feed, and the experimental group was fed with fresh mulberry + concentrate feed, fresh mulberry leaf + 60% compound feed and fresh mulberry leaf + 80% The test period was 49 days. The results showed that feeding “fresh mulberry + concentrate feed” could significantly increase daily gain (P <0.05), feeding “fresh mulberry leaves + compound feed” decreased with the proportion of compound feed (P <0.05). The daily feed intake of fresh mulberry leaves + fine feed supplemented with meat mulching rabbits significantly increased the slaughter rate (P <0.05) (P <0.05). The fresh mulberry leaves fed on fresh mulberry leaves had no significant effect on water content and crude protein in rabbit meat (P> 0.05), which could significantly improve the rabbit meat (P <0.05). The more mulberry leaves fed, the higher the content of inosinic acid in rabbit; the fresh mulberry leaves fed 24 h color, p H 45 min, 45 min b * and 45 min L * (P> 0.05), and significantly increased the values of flesh color 45 min a * and p H24 h (P <0.05), and significantly decreased drip loss (P <0.05) Concentrate supplement “group of meat quality best. The results showed that feeding ”fresh mulberry leaves + fine material supplement" to rabbits could significantly increase daily gain, increase rabbit flavor and improve rabbit meat quality.
