Abstract
A global trend towards removing antibiotic growth promoters (AGPs) from animals reduces intestinal diseases and contributes to the investigation of effective production-sustaining methods in the post-AGP era.Thus, halquinol (HAL) has been used to improve gut health and efficacy.The present study was carried out to evaluate the efficacy of HAL as a substitute for AGPs in broiler chickens.A total of 240 seven-days-old SPF broiler chickens were randomly assigned to four dietary groups and each with twenty birds.The groups were: T0 (control), BD + without HAL; T1, BD + HAL @0.5g/kg feed; T2, BD + HAL @0.75g/kg feed; and T3, BD + HAL @1g/kg feed.On day 35, the broiler chickens fed HAL @1g/kg feed had higher body weight, growth and feed conversion ratio (P<0.05)than the other groups.There was no significant variation in blood profile, however, there were statistically significant differences (P<0.05) in lipid profile parameters among the treatment groups.Furthermore, in a costbenefit analysis, broiler chickens fed HAL @1g/kg feed had a significantly (P<0.05)higher net profit than other dietary treatment groups.Based on the findings of this study, it may be recommended to use HAL supplementation of up to 1g/kg feed as a commercial growth booster for broiler production.
