摘　　要：对犊牛而言,更早地采食饲料,有助于断奶后提高采食量和日增重。使用颗粒状全价配合饲料,能最大限度降低犊牛因日粮变化而带来的胀气及营养性腹泻现象。本试验结合市面上常用的犊牛颗粒料饲料产品,搭配全混合日粮技术,制造断奶犊牛全价配合饲料。全价配合饲料保证犊牛日粮的稳定性的同时,该产品更易使用,在断奶犊牛饲养中推广使用还需进行推广试验。试验结果表明:针对断奶犊牛使用颗粒状的全价配合饲料是完全可行的。蛋白含量与淀粉含量分别为20%和24.1%的全价混合饲料组,平均日增重860 g/头/d,略低于对照组断奶犊牛平均日增重低49 g/头/d。For calves,earlier feed intake helps to increase feed intake and daily weight gain after weaning.The use of granular full-value compound feed can minimize the flatulence and nutritional diarrhea of calves caused by changes in diet.In this experiment,weaning calves were synthesized into full-priced compound feed by combining the calf pellet feed products commonly used in the market and the total mixed diet technology.While the full-priced compound feed ensures the stability of the calf diet,the product is easier to use,and it needs to be popularized in weaning calf feeding.The results show that it is feasible to use granular full-value compound feed for weaned calves.The complete formula feed group with protein content of 20% and starch content of 24.1% had an average daily weight gain of 860 g/head/day,slightly lower than the control group's average daily weight gain of weaned calves by 49 g/head/day.
