摘要
选取160头120日龄平均体重75.9±0.5 kg的育肥猪(杜×长×大)进行复方中草药饲喂试验。试验猪随机分成对照组(不添加复方中草药)、试验Ⅰ组(添加复方中草药1.5 kg/t)、试验Ⅱ组(添加复方中草药2.0 kg/t)、试验Ⅲ组(添加复方中草药2.5 kg/t),每组40头,按照常规方法进行饲养管理。结果:试验Ⅰ、Ⅱ组育肥猪日均增重分别高于对照组53、9 g;试验Ⅲ组低于对照组29 g;试验Ⅰ、Ⅱ、Ⅲ组料重比分别下降12.15%、10.41%、3.01%;日均耗料量分别降低0.21、0.30、0.23 kg。经济效益:试验Ⅰ、Ⅱ组每头育肥猪获利分别高出对照组35.64、48.72元,试验组Ⅲ低于对照组22.72元。
The feeding experiment was carried out on the a total of 160 120-day-old castrated hybrid male pigs(Duroc×Landrace×Large White)with the average initial weight of 75.9±0.5 kg.The experimental pigs were randomly distributed into the control group,groupⅠ(1.5 kg/t),groupⅡ(2.0 kg/t)and groupⅢ(2.5 kg/t),each with 40 heads,the conventional feeding management.The daily weight of fattened pigs in groupⅠand groupⅡwas higher than that of control group 53 g and 9 g respectively,and that in groupⅢwas lower than that of control group 29 g.The weight ratios of groupⅠ,ⅡandⅢdecreased by 12.15%,10.41%and 3.01%respectively.Average daily consumption decreased by 0.21 kg,0.30 kg and 0.23 kg,respectively.In terms of economic benefit,the profits of groupⅠand groupⅡfrom each fattening pig were 35.64 yuan and 48.72 yuan respectively,groupⅢloss 22.72 yuan.
