摘  要：
选用72只断奶10日龄的伊拉兔随机分成4组,分别饲喂4个水平的糖蜜添加日粮(0%、2%、4%、8%),预饲期4 d,正式饲喂期30 d。在正式饲喂期间每日限饲100 g日粮,早晚各50 g,并记录增重与死亡数。正式饲喂第31 d进行屠宰,并分析消化道发育、胰蛋白酶与盲肠纤维素酶酶活以及盲肠微生物数量。结果发现:日粮在0%~8%比例的糖蜜添加范围内,幼兔在增重与料重比的各水平总体差异显著(P=0.034 9)。其增重随着糖蜜比例的提高而提高,料重比反之。因此在此范围内,8%为最适添加水平。同时,引入糖蜜的量与断奶10日龄伊拉兔的增重、料重比、小肠总长度、盲肠纤维素酶酶活、盲肠总菌个数以及乳酸菌个数等指标都存在显著的相关性(P<0.05);与死淘率存在极显著的相关性(P<0.01)。说明糖蜜对于幼兔的生长发育与生产性能存在积极的影响趋势。

摘  要：
The selection of 72 weaned 10-day-old Ira rabbits were randomly divided into 4 groups andfed diets added molasses 4 levels(0%, 2%, 4%,8%), pre-feeding of 4 days, the official feedingof 30 days. During the official feed fed daily lim-it of 100 g diet, morning and night 50 g. And re-cord weight gain and number of deaths. The 31 stday were officially fed slaughter, and analyze the development of the digestive tract, trypsin and cellulase activity of the cecum and cecum microbialpopulation. The results showed that: the diet in the proportion of 0%~8% range of molasses added,young rabbits differences in the overall level of weight gain and feed to gain ratio was significantly(P=0.034 9). Weight gain with a higher proportion of molasses and improved feed conversion ratio. At thesame time, the introduction of molasses to the amount of 10-day-old Ira rabbit weaning weight gain,feed conversion ratio, the total length of the small intestine, cecum cellulase activity, the number of to-tal bacteria and lactic acid number of the cecum and other indicators are there is a significant correla-tion(P <0.05); and death Amoy rate highly significant correlation(P<0.01). Description molasses forthe growth and production performance in the presence of a positive impact on young rabbits trend.
