摘要
【目的】旨在比较分析6~9月龄疆岳驴育成驴补喂预混料的不同饲喂效果,为实现疆岳驴育成驴营养精准供给和驴群结构合理化配置提供技术参考。【方法】选择94头6~9月龄健康的疆岳驴育成驴,分为6月龄组(22头)、7月龄组(32头)、8月龄组(22头)和9月龄组(18头)共4组,在相同饲养管理条件下补喂预混料(含益生菌、维生素、矿物质等),进行为期90 d的营养试验。通过比较同一月龄下不同性别、同一性别下不同月龄疆岳驴育成驴的体重与体尺指标在试验前后的差异,采用独立样本t检验分析各项数据的显著性,进而对试验设计日粮的饲喂效果进行分析与评价。【结果】结果表明,试验前后疆岳驴育成驴母驴6月龄体重、胸深、颈长,7月龄颈长,8月龄尻宽、颈长,9月龄胸宽、颈长均极显著提高(P<0.01);试验前后疆岳驴育成驴公驴6月龄体重、胸深、颈长,7月龄体重、体长、胸围、胸深、头长、颈长,8月龄胸深、颈长均极显著提高(P<0.01);7月龄疆岳驴育成驴公驴的胸围增量极显著高于母驴(P<0.01),7、8月龄疆岳驴育成驴公驴的胸深增量显著高于疆岳驴育成驴母驴(P<0.05);6~9月龄疆岳驴育成驴在补喂预混料后,日均增重范围为0.20~0.27 kg,同月龄不同性别间日增重差异不显著(P>0.05)。【结论】补喂预混料对6、7月龄疆岳驴育成驴具有显著增重效果,且不受性别影响,试验确定的日粮配方有望成为6、7月龄疆岳驴育成驴的专用育肥配方。
【Objective】This study aimed to compare and analyze the feeding effects of premix supplementation for young Jiangyue donkeys aged 6 to 9 months,providing technical references for achieving precise nutritional supply for Jiangyue donkeys during the fattening stage and for rational allocation of donkey herd structure.【Methods】A total of 94 healthy Jiangyue donkeys aged 6 to 9 months were selected and divided into four groups:the 6-month-old group(22 donkeys),the 7-month-old group(32 donkeys),the 8-month-old group(22 donkeys),and the 9-month-old group(18 donkeys).Under the same feeding and management conditions,premix(containing probiotics,vitamins,minerals,etc.)were supplemented for experimental donkeys and a 90-day nutritional experiment was conducted.By comparing the differences in body size and body weight indicators of donkeys before and after the experiment based on different genders(within the same age group)and different ages(within the same gender),the significance of data was analyzed using the independent samples t-test,and then the feeding effect of the designed diet was analyzed and evaluated.【Results】The results showed as follows:for the female donkeys,the body weight,chest depth and neck length at 6 months of age,the neck length at 7 months of age,the rump width and neck length at 8 months of age,and the chest width and neck length at 9 months of age showed extremely significant increase after the experiment(P<0.01);for the male donkeys,the body weight,chest depth and neck length at 6 months of age,the body weight,body length,chest circumference,chest depth,head length,and neck length at 7 months of age;and the chest depth and neck length at 8 months of age showed extremely significant increase(P<0.01);the increase in chest circumference of 7-month-old male donkeys was extremely significantly higher than that of female donkeys(P<0.01),and the increase in chest depth of 7-and 8-month-old male donkeys was significantly higher than that of female donkeys(P<0.05);after supplemental feeding of premix to donkeys at the age of 6 to 9 months,the average daily weight gain ranged from 0.20 kg to 0.27 kg,and the difference was not significant between different genders of the same month of age(P>0.05).【Conclusion】Supplementary feeding of premix significantly increased the weight of 6-and 7-month-old Jiangyue donkeys,and the effect was not influenced by gender.The diet formula of this experiment was expected to serve as a special fattening formula for 6-and 7-month old donkeys.
