				Relative efficacy of organic acids and antibiotics as growth

				Abstract 
 
				
				
				Aim: 
				
				The objective of this study was to evaluate the effect of 
				organic acids as replacer to antibiotics in their various 
				combinations on feed consumption, body weight gain, and feed 
				conversion ratio (FCR) in broiler chicks during different phases 
				of growth. 
				
				
				Materials and Methods: 
				
				Antibiotics and organic acids were incorporated into boiler feed 
				in different combinations to form 10 maize based test diets (T1 
				to T10). Each test diet was offered to four replicates of 10 
				birds each constituting a total of 400 birds kept for 45 days. 
				
				
				Results: 
				
				Significantly better effect in terms of body weight gain from 
				supplementation of 1% citric acid and 1% citric acid along with 
				antibiotic was observed throughout the entire study, whereas the 
				effect of tartaric acid supplementation was similar to control 
				group. Citric acid (1%) along with antibiotic supplementation 
				showed highest feed intake during the experimental period. 
				Significantly better FCR was observed in groups supplemented 
				with 1% citric acid and 1% citric acid along with antibiotic 
				followed by antibiotic along with organic acids supplemented 
				group. 
				
				
				Conclusion: 
				
				Growth performance of birds in terms of body weight, body weight 
				gain, and FCR improved significantly in 1% citric acid which was 
				significantly higher than antibiotic supplemented group. 1% 
				citric acid can effectively replace antibiotic growth promoter 
				(chlortetracycline) without affecting growth performance of 
				birds.
