Abstract
Antibiotics have been used in poultry to improve growth performance but due to their side effects European Union has banned use of antibiotic as growth promoters in animal feed in 2006. Such situations has resulted in search for natural and safe alternatives, therefore, this study was undertaken to compare the efficacy of commercial herbal growth promoter as dietary inclusion on performance, minor body parts weight and immune response in broiler. A total of 120 healthy day old Hubbard chicks of uniform body weight were divided into 12 experimental units of 10 chicks each. These experimental units were further allotted to 4 treatment groups (T1, T2, T3 and T4) such that each treatment received 3 replicates. Group A was fed ration without supplementation of commercial herbal products i.e. control whereas group B, C and D were fed ration supplemented with commercial herbal products i.e. Bio-Mix, Respecine and A one Formula respectively each @ 100 g/ 50 kg of commercial feed. Each experimental unit of the chicks was reared in a separate pen. The birds were kept under similar managerial conditions. Feed intake, weight gain and FCR was better in group C fed respecine supplemented diet (P 0.05). Use of various commercial herbal growth promoters in the ration exhibited an increase in the profit margin of broilers. Broilers reared on respecine fetched maximum profit as compared to other groups.
Highlights
Poultry industry is continuously progressing through improvement of genetic potential of new broiler strains to provide high biological value protein for the human population [16]
Antibiotic have been used in poultry for the past four decades to improve growth performance and the total use of antibiotics as a growth promoter is estimated to be 4500 tons per year provided by 137 million tons of poultry feed production their usage in poultry industry is intensively controversial because of the development of bacterial resistance and potential consequence on human health [8,15]
The highest weight gain was recorded in the birds of group C fed ration supplemented with respecine
Summary
Poultry industry is continuously progressing through improvement of genetic potential of new broiler strains to provide high biological value protein for the human population [16]. Antibiotic have been used in poultry for the past four decades to improve growth performance and the total use of antibiotics as a growth promoter is estimated to be 4500 tons per year provided by 137 million tons of poultry feed production their usage in poultry industry is intensively controversial because of the development of bacterial resistance and potential consequence on human health [8,15]. European Union has banned use of antibiotic as growth promoters in animal feed in 2006. Such situations has resulted in search for natural and safe alternatives in form of prebiotic, probiotic, enzymes, herbal products, immune modulators, organic acid etc. Such situations has resulted in search for natural and safe alternatives in form of prebiotic, probiotic, enzymes, herbal products, immune modulators, organic acid etc. to maintain optimum growth rates [4,17]
