A Survey on Effect of some Common Growthpromoters on Growth Factors of Broiler Chickens
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 11
Abstract
The present research seeks to investigate the influence of some common growth promoters (Prebiotics, Probiotics, Antibiotics, Asidfires and Synbiotics) on growth factors of broiler chickens. 240 one-day Ross 308 chickens were divided into 6 groups: A, B, C, D, E, F. Group B received 150 gr/ton Virginamycin, group C received Protexin with average dose of 100 gr/ton, group D received 6 kg/ton Salkyn, group E received 3 Kg/ton A-Max and group F received 1 kg/ton Synbiotic while group A received no growth-promoter. Effective factors which were evaluated included: consumption of food, weight increase, feed conversion coefficient (FCR) and rate of death. During the study, there were not any meaningful differences regarding weight increase, consumption of food, and feed conversion coefficient (FCR) among treatments with growth promoters. However, all treatments had more beneficial effectives in compare with control group. According to the obtained results, prebiotics and synbiotics are better growth-promoters than others. However, asserting such findings and other aspects of growth-promoters in nutrition of broiler chickens requires more studies.
