【摘要】 用48头生长育肥猪分成4组进行120 d试验,比较以油菜籽饼和鱼粉作为蛋白质来源组成的饲粮对生长育肥猪的平均日增粮重,饲料报酬及经济效益的影响,结果表明,各组日增重和饲料报酬均无明显差异(P>0.05);菜饼代替50%鱼粉或菜饼代替100%鱼粉另加赖氨酸,蛋氨酸的饲粮在消化能手和粗蛋白质水平与鱼粉饲粮类似时,可取得与饲喂鱼粉时同样的饲养效果。更多还原

【Abstract】 The experiment was conducted to compare average daily gain(ADG)and feed efficiency (FE) with fish meal and rapeseed cake protein (RCP) forprotein source in 4 groups of pigs for 112 days. The feed comsumption andbody weight of the 48 pigs were recorded at 35 kg, 60 kg, 90 kg empty body wei-ght. The result indicated that ADG of the 4 groups were 0.64kg, 0.67kg,0.61 kg, 0.66 kg respectively. There were no significant differences in the ADGbetween the 4 groups (P>0.05).The FE of the 4 groups were 3.71, 3.58, 3.86,3,73:1 respectively. There were no significant differences in the FE betweenthe 4 groups (P>0.05). Replace of 50% fish meal with RCP or 100% replacesupplemented with 0.2% methionine and lysine at similar energy and crudeprotein level showed the same effects for growing-fattening pigs.更多还原
