摘要: 本试验以6月龄伊犁马驹为试验动物,饲喂不同水平的精料补充料,通过全收粪、收尿法进行消化代谢试验,探究饲喂不同水平的精料补充料对6月龄伊犁马消化代谢、血液生化指标及体增重的影响,为6月龄伊犁马驹的科学饲喂提供依据。试验选用平均体重为(145.28±1.69) kg的6月龄断奶伊犁公马驹20匹,随机分为4组,每组5匹,分别为试验Ⅰ、Ⅱ、Ⅲ及Ⅳ组,各组每匹马每天饲喂4 kg苜蓿干草,在此基础上分别饲喂精料补充料0.4、0.6、0.8、1.0 kg。进行20 d的消化代谢试验,其中预试期16 d,正试期4 d。结果表明,随精料补充料饲喂水平的增加6月龄伊犁马马驹对营养物质的摄入量,干物质、有机物、粗蛋白质、钙的消化量,以及消化能、代谢能、氮沉积率、钙沉积率均增加,对6月龄伊犁马马驹血浆中总蛋白、球蛋白、白蛋白及血液尿素氮含量均无显著影响(P > 0.05),但6月龄伊犁马马驹血液中球蛋白的含量有增加的趋势,血液中尿素氮的含量有降低的趋势;此外试验期内平均日增重随精料补充料饲喂水平的增加呈上升趋势。因此,增加6月龄伊犁马马驹精料补充料的饲喂水平可提高营养物质摄入量、消化率及沉积率,还可增强机体免疫能力、促进氮沉积并提高马驹的平均日增重。

Abstract: 6 months old Yili foals were used as the experimental animal fed with different levels concentrate supplement to study the effects of fed with different levels concentrate supplement on digestion and metabolism,blood biochemical indexes and body weight gain by total feces and urine collection method,provide evidence for 6 months old Yili foals feeding.According to similar weight,20 weaned 6 months old Yili foals (all males) whose average weight was (145.28±1.69)kg were randomly divided into 4 groups named groups Ⅰ,Ⅱ,Ⅲ and Ⅳ,each group of 5 weaned Yili foals(all males).All Yili foals were fed with alfalfa 4 kg/d,basised on this,groups Ⅰ,Ⅱ,Ⅲ and Ⅳ were fed with 0.4,0.6,0.8,1.0 kg/d concentrate supplement.20 d digestion and metabolism experiment,comprised 16 d adaptation and 4 d collection.The results showed that as the amount of concentrate supplement feeding increased,nutrition intake,amount of nutrient digestion of DM,OM,CP,Ca,DE,ME,retention rate of N,Ca increased.There were no significant effects on the content of TP,GLB,ALB,and BUN in plasma of 6 months old Yili foals(P > 0.05),but the content of TP,GLB in plasma showed an increased trend,the concentration of BUN in plasma showed a decreased trend.The ADG of 6 months old Yili foals was gradually increased as the amount of concentrate supplement feeding increased.Therefore,increasing amount of concentrate supplement feeding of 6 months old Yili foals could increase the nutrient intake,digestion rate and retention rate,also could strengthen the body's immune ability,improved nitrogen deposition and the average daily gain.

Key words: Yili foals; concentrate supplement; digestion and metabolism; blood biochemical indexes; body weight gain
