Evaluation of Suitable Doses of Hot Chilli Powder as Effective Alternative of Antibiotics on Growth Performance of Broiler

Abstract

In this study, chicks were treated with different doses of chilli powder to evaluate the physical, biochemical, pathological and economical parameters of broiler. Chilli powder was applied on 480 broiler chicks. A basal diet was supplemented with 1g/L antibiotic (positive control), 0g antibiotic (negative control), 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0% chilli powder. At the age of 28 days, the feed conversion ratio of 2.0% and 2.5% chilli powder was found lower as compared to antibiotic and control. There was no negative impact found on dressing percentage of broilers which was tested by different doses of chilli powder. In this research, significant (P<0.05) higher blood glucose level was found in chilli powder as compared with antibiotics. Blood cholesterol was significantly lower (P<0.05) in 2.0%, 2.5%, 3.0% chilli powder as compared with antibiotics. SP ratio for Gumboro and Newcastle disease of 2.0%, 2.5%, 3.0% chilli powder were significantly (P<0.05) higher as compared to the antibiotics. E. coli population of all treatments were significantly (P<0.05) lower as compared to control. In economic point of view, 2.0% chilli powder was found more profitable as compared to antibiotics. Considering all the results of the present experiments, it may be concluded that poultry farmers may use 2.0% chilli powder with broiler feed as safe alternative of the traditional antibiotics and they may get more profit rather than antibiotics. Moreover, the 2.0% dietary supplementation of chilli powder may lead to the development of low-cholesterol chicken meat and may fulfill the demanded of meat for health-conscious consumers.
