摘要
本试验选60头6月龄肥育猪随机分为四组,在基础日粮中用不同比例的发酵鸡粪(10%、20%、30%)代替等量的混合料,并设立对照组,试验期21天。结果表明,各试验组与对照组的平均日增重无显著差异(P>0.05)。其中以30%的发酵鸡粪代替等量混合料,每公斤增重可节省混合料26.48％,可降低饲料成本15.98％。我们认为,在猪日粮中以适当比例发酵鸡粪代替部分混合料不明显影响增重,具有降低成本,提高经济效益的优点,在生产中是可行的。
Four groups of fattening pigs aged 6 month (15 pigs for a group) were fed with the same amount of a series of daily mixture diets containing different proportional chicken fermentable manure (control, 10%、20%、30%) respectively for 21 days the rsults showed no signiflcont diffence in the average daily weight gain between each treatment and the control.Fed with 30% chicken fermentable manure, 26.48% daily mixture diet and 15.98% cort were saved for a kg pig weight gain.Therefore,daily considerable amount of chickeen fermentable manure into the daily mixture diet had no adverse effect on the weight gain of pigs, and the economic method was suggested to be used in practice.
