ácidos organicos em ra？？es de poedeiras comerciais

organic acids are incorporated to the poultry feeds to control salmonella and moulds. however, there is little information about its effect on the performance of laying hens. thus, this work was undertaken to study the incorporation of organic acids on the laying hens eggs production. they were placed in 3 groups of 25 animals. birds in group i were fed with ration containing organic acid for 4 weeks; birds in group ii received ration containing organic acid for 8 weeks, and birds in group iii were fed with ration without organic acid (control group). egg production, body weight, egg weight and egg quality were the analyzed parameters. with base on the results of the incorporation of organic acid into the feed for 4 or 8 weeks improved the egg production, and the body weight (p>0.05) but the egg weight and egg quality were not affected.
