摘要
试验选取27头健康的荷斯坦犊牛,随机分为3个处理组,每组9头犊牛,每头犊牛1个重复,三组分别饲喂糖蜜添加量为0%、5%、10%的日粮,试验期8周。结果发现,与不添加糖蜜的对照组相比,5%糖蜜组犊牛的生产性能有所下降,10%糖蜜组犊牛生产性能稍有提升。添加10%糖蜜组犊牛开食料的总采食量比对照组多出3.29kg,增加了9.28%;整个试验期的增重相比对照组增加了0.612kg,日均增重提高了0.01kg,提高了1.31%;犊牛每千克增重所需牛奶及开食料成本减少0.148元。
The experiment was aimed to study the effect of adding different proportions of molasses to the granular starter on the growth performance and weight gain cost of calves.The experiment selected 27 healthy Holstein dairy calves and randomly divided them into three treatment groups,group contained nine replicate and each replicate contained one calf,and feed the calf starter with 0%,5%,and 10%molasses respectively,the trial period is 8 weeks.It was found that compared with no molasses,the production performance of the 5%molasses group was reduced,and the production performance of the 10%molasses group was slightly improved.Compared with no molasses added,the total feed intake of calves in the 10%molasses group increased by 3.29kg,an increase of 9.28%;the end weight of the calves in the 10%molasses group increased by 0.612kg,an average daily increase during the test period The day weight increased by 0.01kg,and the average daily weight gain increased by 1.31%.The 10%molasses group reduces the cost of milk and starter feed per kilogram of weight gain for calves in the 0%molasses group by RMB 0.148.
