841复合饲料添加剂对生长育肥猪增重效果的研究

Effect Study on 841 Compound Feed Additive Feeding Growth-fattening pig

以红薯干20％、30％、50％～56％配合基础日粮，分别饲喂前期、中期、后期二元杂交生长育肥猪，对照组饲喂基础日粮，试验组添加841复合饲料添加剂．试验从体重20kg开始，至90kg结束．5批次试验结果：试验组技对照组缩短饲养期55.5天，日增重增加211g，提高53％，每千克增重降低饲料消耗1．17kg，差异均极显著（P＜0.01）．

Two-Way Crossed growth-fattening pigs were fed basic diet and 20%, 30%, 50% ~ 60% dried sweet potato for ealier,middle and later Periods. The diets of experiment groups were added 841 co npound feed additive,the control group fed only basic diet. Experiment period was from body weight 20kg to 90kg. The results from 5 batches of experiments were that the experiment group shortened 55. 5 days of Feeding periad,increased daily gain 211g (increased 53% ),and feed consume per kilobody weight decreased 1. 17 kg (P＜0.01 ).
