| Popis: | This study aims to utilise thyme oil (TO) as a natural growth promoter in comparison to mannanoligosaccharides (MOS) for broilers raised under hot climates from 1 to 28 days of age. Thus, a total of 180, day-old broilers chicks were divided into five groups (36 broilers/group in 6 replicates of 6 broilers/replicate). The chickens were fed the same corn-soybean meal basal diet and were submitted to one of the following five dietary treatments: (a) positive control group, fed the basal diet supplemented with MOS at 1g/kg feed; (b) negative control group, fed the basal diet without supplementation; (c) thyme oil 1.0 (TO_1.0) group fed TO at 1.0 g/kg feed, (d) thyme oil 1.5 (TO_1.5) group fed TO at 1.5 g/kg feed and (e) thyme oil 2.0 (TO_2.0) group fed TO at 2.0 g/kg feed. The TO_1.0 displayed a better feed conversion ratio (FCR) than did the other treatments (p |
