【摘要】：本论文通过饲喂不同的精料补充料,研究对梅花鹿各营养物质消化率、血清生化指标及生产性能的影响,确定梅花鹿精饲料理想饲料配比添加水平,为梅花鹿日粮配制及其科学饲养提供理论依据。试验一:从2013年7月15日到2013年8月30日于吉林农业大学鹿场,进行育成期母鹿不同精料补充料的饲养和消化试验。本试验选用吉林农业大学鹿场、吉林双阳鹿业良种繁育有限公司、长春双阳区虹桥鹿业有限公司精饲料为基础日粮,选取健康、1周岁龄、体重接近的育成期母鹿21头。随机分为A、B、C 3组,分别饲喂三种不同配方的饲料。试验后期进行为期7d的消化试验。试验结果如下:1.不同的精料补充料对育成期母鹿干物质的采食量,A、B、C 3组间差异显著(P0.05),C组(高蛋白组)最高;2.不同的精料补充料对育成期母鹿干物质、粗脂肪、粗纤维消化率的影响不显著(P0.05),粗蛋白消化率,C组显著高于A、B组(P0.05)。钙、磷摄入量C组B组A组;3.不同的精料补充料对育成期梅花母鹿日增重差异显著(P0.05),C组平均日增重最大为118.50g。试验二:从2014年6月10日-2014年7月17日分别于吉林农业大学鹿场、吉林省双阳鹿业良种繁育有限公司、长春市双阳区虹桥鹿业有限公司进行生茸期公鹿不同配比精饲料的饲养和消化试验。试验鹿分别选用48头、45头、48头体重接近的4-5岁雄性梅花鹿,各分3圈饲养。采集样本,分析在不同精料补充料配方下,公鹿营养物质消化率、血液相关生化指标和产茸量的差异。结果如下:1.不同精料补充料对生茸期梅花公鹿干物质及有机物的采食量影响显著(P0.05),其中Ⅱ组最高;2.不同精料补充料对生茸期梅花鹿干物质消化率、粗蛋白消化率均影响显著(P0.05),且Ⅱ组Ⅰ组Ⅲ组。3.不同精料补充料对生茸期梅花公鹿血清中总蛋白以及尿素氮浓度影响显著(P0.05);日粮蛋白质水平与血清尿素氮浓度关系密切。4.不同精料补充料对公鹿的产茸量无显著影响(P0.05),本试验设计范围内,Ⅱ组(低能高蛋白组)最高。综上,在本试验设计范围内,育成期梅花鹿母鹿精料补充料适宜的蛋白质水平为21.43%,生茸期梅花鹿公鹿采用粗蛋白含量20.05%、能量16.74MJ?kg-1的精料补充料配方时,生产性能最佳。
[Abstract]:In this paper, the effects of different concentrate supplements on the digestibility of nutrients, serum biochemical indexes and production performance of sika deer were studied, and the ideal feed proportion of sika deer concentrate was determined. To provide theoretical basis for ration preparation and scientific feeding of sika deer. Experiment 1: from July 15, 2013 to August 30, 2013, the feeding and digestion experiments of different concentrate supplements for female deer were carried out in Luchang, Jilin Agricultural University. In this experiment, Jilin Agricultural University Luchang, Jilin Shuangyang Deer Industry breeding Co., Ltd., Changchun Shuangyang District Hongqiao Deer Industry Co., Ltd. Group C 3 was randomly divided into three groups, which were fed with three different formulations of feed. A 7-day digestion test was conducted at the later stage of the trial. The test results are as follows: 1. There was significant difference in dry matter intake between different concentrate supplementation groups (P0.05) and high protein group (high protein group). The effects of different concentrate supplementation on dry matter crude fat and crude fiber digestibility were not significant (P0.05). The crude protein digestibility of group C was significantly higher than that of group A (P0.05). Calcium and phosphorus intake group C group B group A group 3. The average daily gain (ADG) of group C was 118.50 g. Experiment two: from June 10, 2014 to July 17, 2014 at Luchang, Jilin Agricultural University, Jilin Shuangyang Deer breeding Co., Ltd. The experiment of feeding and digesting of different ratio concentrate of male deer in antler stage was carried out in Hongqiao Deer Industry Co., Ltd., Shuangyang District, Changchun City. Forty-five male sika deer of 4-5 years old were selected and fed in 3 turns. The differences of nutritional digestibility, blood biochemical indexes and antler production of male deer under different concentrate supplement formula were analyzed. The result is as follows: 1. The effect of different concentrate supplementation on dry matter and organic matter intake of sika male deer in antler stage was significant (P0.05), among which group 鈪，
