Abstract
Present review article was designed with the aim to see the effect of organic bio-stimulator on the performance of broilers. Due to rapid urbanization and industrialization, the demand for meat, particularly tender chicken poultry meat (broiler) is rapidly increasing day by day. The cost of feeding in poultry production alone accounts for 60 to 70% of the total farm expenditure. This cost can be minimized to some extent by adding some of the growth stimulators in the broiler chicken feed. Result revealed that a large number of growth promoting agents and herbal products are occasionally being used in poultry feed to produce lower feed intake, higher growth rate, disease resistance and higher live weight gain in the poultry. Beside, above biochemical and heamotological attributes including carcass traits is also improved. Further, the ban on the use of synthetic growth promoters in farm animals due to its residual effects on consumers and resistance build up by pathogens or bacteria necessitates the use of natural symbiotic growth promoters. Key words: Biochemical, broiler, carcass, growth, heamotological.
Highlights
India is the fifth largest producer of poultry meat in the world after USA, China, Brazil and Mexico (Executive guide, 2006)
An experiment was conducted under completely randomized design with five replicates and 150 chicks per experimental unit was used to evaluate the effect of growth promoters on feed intake, liveweight gain and feed:weight gain ratio of broilers (Correa et al, 2003)
It was shown that the growth; liveweight gains; carcass composition, yield and weight and meat quality of broilers in the feed additive groups were better than the control group, where the best results were obtained by Group II birds for both males and females
