本试验旨在通过套算法研究不同替代比例的花生秧对生长獭兔的表观消化能和营养物质表观消化率的影响.试验将24只75日龄平均体重(1.72±0.31) kg的健康白色獭兔随机分为4组,每组6个重复,每个重复1只.对照组饲喂基础饲粮,试验组分别饲喂10%、15%和20%花生秧替代基础饲粮的试验饲粮.预试期和正试期各7 d.结果显示,生长獭兔对10%、15%和20%替代组花生秧的表观消化能分别为7.97、8.20和7.88 MJ/kg,对10%、15%和20%替代组花生秧的总能、干物质、粗灰分、粗蛋白质、粗纤维、中性洗涤纤维、酸性洗涤纤维、粗脂肪、钙、磷和无氮浸出物的表观消化率分别为:58.03%、51.62%、62.07%、62.36%、24.09%、35.58%、25.28%、81.57%、51.24%、51.49%、56.23%;59.73%、55.46%、68.70%、69.43%、28.41%、41.89%、29.38%、83.32%、56.84%、59.99%、60.65%和57.37%、51.51%、59.34%、60.59%、23.29%、36.90%、24.58%、78.59%、52.95%、65.50%、60.62%.由此可见,生长獭兔对不同替代比例花生秧的各营养物质的表观消化率是具有一定的差异性,其中15%替代组花生秧各营养物质的表观消化能和表观消化率相对较高.

This experiment was conducted to study the apparent digestible energy and nutrient apparent digestibility in peanut vine with different substitution ratios of growing Rex rabbits using the substitution method. Twenty four 75-day-old white growing Rex rabbits with an average body weight of (1.72±0.31) kg were randomly divided into 4 groups with 6 replicates per group and 1 rabbit per replicate. Rabbits in the control group were fed the basal diet, and the others in the experimental groups were fed the experimental diets which used 10%, 15% and 20% peanut vine substituted the basal diet, respectively. The preliminary trial period and the trial period were both lasted for 7 days. The results showed that the apparent digestible energy were 7.97, 8.20 and 7.88 MJ/kg in 10%, 15% and 20% substitution groups of growing Rex rabbits, respectively. The apparent digestibility of gross energy, dry matter, crude ash, crude protein, crude fiber, neutral detergent fiber, acid detergent fiber, ether extract, calcium, phosphorus and nitrogen free extract in 10%, 15% and 20% substitution group were 58.03%, 51.62%, 62.07%, 62.36%, 24.09%, 35.58%, 25.28%, 81.57%, 51.24%, 51.49%, 56.23%; 59.73%, 55.46%, 68.70%, 69.43%, 28.41%, 41.89%, 29.38%, 83.32%, 56.84%, 59.99%, 60.65% and 57.37%, 51.51%, 59.34%, 60.59%, 23.29%, 36.90%, 24.58%, 78.59%, 52.95%, 65.50%, 60.62%, respectively. In conclusion, there are certain differences in nutrients apparent digestibility of different substitution ratios peanut vine for growing Rex rabbits. Rex rabbits fed the diet substituted by 15% peanut vine has higher nutrients apparent digestible energy and apparent digestibility.
