245			_aEffect Of Replacement Of Fed Aditive Antibiotic With Different Levels Of Lactic Acid On Broiler Performance

502			_aThe research study was conducted to find out the effect of replacement of feed additive antibiotic Le. flavomycin with different levels of lactic acid, on broiler performance. The parameters were growth rate, feed intake, feed efficiency mortality and economics. For this Two hundred day-old broiler chicks were randomly divided into five groups of forty chicks each. Two experimental rations (starter and finisher) were prepared and fed to the experimental chicks upto 42 days of age. Lactic acid 1%, 2% and 3% was supplemented in the rations for group B, C and D respectively. Flavomycin was supplemented in feed for group E and group A was a control group. The data thus collected was analyzed statistically. The results revealed that the ration with 1% lactic acid supplementation resulted in more feed consumption, good FCR and did not prove economical. 2% lactic acid supplementation did not prove beneficial in any aspect, whereas the addition of 3% concentration of lactic acid in feed resulted in more feed consumption, good weight gain but again it was not economical. The feed supplemented with flavomycin also consumed more feed, provided good weight gain and proved to be the only economical supplementation. In terms of feed intake, the control groups served to be the best with minimum feed intake by the birds. Based on this research, we can conclude that adding organic acids to broiler chicken feed, improves production results, although the positive effect of organic acids is less than that achieved by growth promoting antibiotics. 1-lowever, the use of lactic acid is not economical as compared to feed additive antibiotic, being a natural product of bacterial/fungal fermentation. So the use of lactic acid in broiler ration could be of economical importance, if lactic acid is produced at a low cost.
