摘要

本试验旨在研究饲粮中不同比例全株玉米青贮对疆岳驴生长性能、营养物质表观消化率及血清生化指标的影响。选取体况良好的2周岁、平均体重为（144.82±0.65）kg的疆岳驴育成母驴30头，随机分为5组，每组6头，饲喂能量和蛋白质水平接近但全株玉米青贮（裹包青贮）占粗饲料比例分别为0（对照组）、10%、20%、30%和40%的5种饲粮。试验期103 d，前12 d为预试期，后91 d为正试期。结果显示：1）与对照组相比，10%组、20%组、30%组和40%组的平均日增重分别提高了25.42%（P>0.05）、10.78%（P>0.05）、23.05%（P>0.05）和45.88%（P<0.05）；10%组、30%组和40%组的料重比分别降低了18.65%（P>0.05）、23.57%（P>0.05）和32.66%（P<0.05）。2）10%组粗蛋白质、总能、总磷表观消化率极显著低于对照组（P<0.01）；30%组粗脂肪表观消化率极显著高于对照组（P<0.01）；40%组粗脂肪、总能、中性洗涤纤维、酸性洗涤纤维、钙表观消化率极显著高于对照组（P<0.01）。3）与对照组相比，10%组血清白蛋白、尿素氮含量显著升高（P<0.05）；20%组血清尿素氮含量以及谷草转氨酶、谷丙转氨酶活性显著升高（P<0.05）；30%组血清谷丙转氨酶活性极显著升高（P<0.01），血清尿素氮、葡萄糖、总胆固醇含量和碱性磷酸酶活性显著升高（P<0.05）；40%组血清葡萄糖、总胆固醇、高密度脂蛋白胆固醇含量和碱性磷酸酶、谷草转氨酶活性显著升高（P<0.05）。由此得出，在本试验条件下，以生长性能、营养物质表观消化率及血清生化指标为评价依据，以全贮玉米青贮占粗饲料40%的比例饲喂2周岁疆岳驴效果最优。

Abstract

The purpose of this experiment was to study the effects of different proportions of whole corn silage in diets on the growth performance, nutrient apparent digestibility and serum biochemical indices of Jiangyue donkeys. Thirty female donkeys were bred from Jiangyue donkeys with an average body weight of (144.82±0.65) kg and at the age of 2 years in good physical condition. They were randomly divided into 5 groups, each group with 6 heads, and were fed diets with similar energy and protein levels but different proportions of whole corn silage. The proportion of silage (wrapping package silage) in roughage of 5 diets was 0 (control group), 10%, 20%, 30% and 40%, respectively. The test period lasted for 103 days, the first 12 days were the pre-test period, the trial period is 91 days. The results showed as follows:1) compared with the control group, the average daily gain (ADG) of the 10%, 20%, 30% and 40% groups was increased by 25.42% (P>0.05), 10.78% (P>0.05), 23.05% (P>0.05) and 45.88% (P<0.05), respectively (P<0.05). The feed/gain (F/G) of the 10%, 30% and 40% groups was 18.65% (P>0.05), 23.57% (P>0.05) and 32.66% (P<0.05) lower than the control group, respectively. 2) The apparent digestibility of crude protein, gross energy and total phosphorus of the 10% group was significantly lower than that of the control group (P<0.01). The apparent digestibility of ether extract of the 30% group was significantly higher than that of the control group (P<0.01). The apparent digestibility of ether extract, gross energy, neutral detergent fiber, acid detergent fiber and calcium in the 40% group was significantly higher than that of the control group (P<0.01). 3) Compared with the control group, the serum albumin and urea nitrogen contents of the 10% group was significantly increased (P<0.05); the serum urea nitrogen content, aspartate aminotransferase and alanine aminotransferase activities of the 20% group were significantly increased (P<0.05); the serum alanine aminotransferase activity of the 30% group was significantly increased (P<0.01), and the serum urea nitrogen, glucose, total cholesterol contents and alkaline phosphatase activity were significantly increased (P<0.05); the contents of glucose, total cholesterol, high-density lipoprotein cholesterol and the activities of alkaline phosphatase and aspartate aminotransferase of the 40% group were significantly increased (P<0.05). It is concluded that under the conditions of this experiment, the best feeding effect of Jiangyue donkeys is obtained by using the whole corn silage, which accounts for 40% of the roughage, based on the growth performance, nutrient apparent digestibility and serum biochemical indices.

Key words： whole corn silage; Jiangyue donkeys; growth performance; nutrient apparent digestibility; serum biochemical indices
