摘  要：
选用83.0 kg左右日龄相近、健康无病杜长大三元杂交育肥猪60头,按照体重相近的原则随机分到4个组中,每组5个重复,每个重复3头猪。对照组饲喂常规日粮,处理1、2、3组分别饲喂添加17.9%、35.8%、53.7%新鲜发酵木薯渣的饲粮(分别等同于使用5%、10%、15%的风干发酵木薯渣饲粮)。风干基础,各组日粮除粗纤维水平不同外,其余营养指标基本接近,研究不同用量发酵木薯渣对育肥猪生产性能的影响,并分析其经济效益。试验结果显示:1生产性能:肥育猪饲粮中处理1、2组对猪生产性能没有显著影响,但处理3组生产性能显著低于对照组,日增重、料重比分别比对照组低268.6 g/d、10.29%;2经济效益:与对照组相比,单位增重饲料成本处理1、2组分别节约0.9元、0.7元,处理3与对照组相同。综合生产性能和经济效益,从废物利用、环境保护的角度看,在不明显影响猪只生产性能的情况下,肥育猪日粮可以使用低于35.8%新鲜发酵木薯渣。

摘  要：
60 healthy DLY crossbred pigs with an initial body weight of about 83 kg were randomly dividedin to 4 groups of control and trial 1, 2, 3, 5 replicates for each group, each repeat of three pigs. The control group was fed routine diet; the trial 1,2,3 was fed on the compound diet adding with 17.9%, 35.8%, 53.7% fresh cassava dregs fermentation(equal to the compound diet with 5%, 10%, 15% air-dry cassava dregs fermentation).Base on air-dry, except crude fiber level are different, the nutritional indexes of all diets are approach. The purpose of the experiment is to study the effect of different doses of cassava dregs fermentation on production performance, economic benefit of fattening pigs. The results show that:1production performance:Production performant(the daily weight gain, daily feed intake and feed gain ratio)were not significant different(P>0.05) between control and trial group 1,2, but production performance were significantly difference(P<0.05) between control and trial group 3. The daily weight gain and the feed utilization efficiency were decreased by 268.6 g/d and 10.29% in the trial group 3. 2economic benefit: Compared with the control group, the feed cost per kilogram weight gain of trial group 1,2 save 0.9, 0.7 Yuan, and the feed cost per kilogram weight gain of trial group 3 is same. Combining with production performance and economic benefit, from the use of waste, environmental protection point of view, but has no influence on the production performance of pigs case, finishing pig diet can use less than 35.8% of fresh cassava dregs fermentation.
