Abstract: On the basis of the experiments of feeding pigs with cllicken manure carried out at Heheng ecological pig raising farm and Guquan exerimcntal farm of ecological engineering, the effect of feeding pigs with chicken manure on the growth of pig and its benefit were investigated. The amount of ingestive feed and weight gain of the pigs were determined, and the amion acids in the pork and economic profits were analyzed., The results show that when the nutrient levers in the pig-feed is lower, the growth of the pigs can be promoted by adding proper amount of cllicken manure into the pig-food, and the nutrient quality of the pork arc not affected. No matter how the nutrient levers of the pig-feed arc, it is suggested that the best economic benefit can be achieved by adding about 30% chickcn manure into the pig-feed.
