中文摘要：
为探索木薯渣生物饲料对桂科商品猪生长性能的影响,试验选取24头日龄、体重相近的桂科商品猪,随机分成4组,每组6头。分别饲喂含木薯渣生物（多酶肽）饲料为0、2%、4%、6%的日粮,饲养试验时间为45 d。结果表明,在日粮中添加2%木薯渣生物饲料使桂科商品猪日增重较对照组提高21.52%,屠宰率提高5.8%,每千克增重成本降低了8.38%（P〉0.05）。由此可见,日粮中添加2%木薯渣生物饲料可明显提高桂科商品猪的日增重,降低料重比,降低饲养成本,提高桂科商品猪的经济效益。
英文摘要：
In order to reveal effect of biological feed from cassava residue on the growth performance of Guike pigs, a total of 24 pigs were divided into four groups,each group had 6 pigs. Pigs were fed with four experimental diets containing 0%, 2%, 4%, 6% biological feed from cassava residue for 45 d. The result implied that compared with control group, the average daily gain and the dressing percent- age of 2% group were increased 21.52%, 5.8% respectively, and the cost of 1 kg weight gain was cut by 8.38%. Results and economical analysis demonstrated that the biological feed from cassava residue level of 2% was the most effective and economic.
