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.
