| 摘 要： | 犊牛使用代乳品可以节省鲜奶，降低饲养成本，控制疾病的发生，促进消化系统的发育。试验用24头犊牛做试验，60日龄断奶。结果表明，代乳品组犊牛增重47．55千克；对照组增重41．72千克；吃代乳品的犊牛在30-60日龄的日增重达到1026克，高于对照组103克。吃代乳品的犊牛每增重1千克的直接饲料成本为15．13元，比鲜奶组犊牛低2．14元／千克。

| Abstract: | Milk replacers can make it possible that dairy calf consumes less whole milk from birth to weaning,disease can be controlled and digestive system of neonatal calve develops well. An experiment with 24 Holstein calves was designed to study the effect of milk replacer on growth, disease and economical trait. 12 neonatal calves fed colostrums during the first 5 days, followed by milk replacer up to 60-d. The other 12 calves fed whole milk in the experiment. Mean body weight gain during 60-d study was 47.55 kg and 41.72 kg for calve fed milk replacer and whole milk respectively. The feeding cost of calves fed milk replacer was reduced by RMB 2.14 yuan per kg body weight compared with calves fed whole milk. |
