The Effect of Dietary Supplementation of Yeast and Humate on Broiler Performance and Some Slaughter Characteristics

16196

In this study, effects of dietary antibiotic (avilamycin, 20 mg/kg feed), humate (humicacid+fulvic acid, 300 mg/kg), yeast (3g/kg feed) and mixture of humate and yeast (300 mg humicacid-fulvic acid+2 g yeast/kg feed) supplementation to diets on the performance, carcass yield, weight of liver and length of intestine of broilers was investigated. A total of one thousand and two hundred and fifty one-day-old broiler chicks of mixed sex (Ross-308) were randomly assigned to 5 treatment groups, each with 5 identical subgroups. All of the feed additive preparations significantly improved body weight and feed conversion ratio between 1 and 28 days (P 0,05). While body weight differed significantly among treatments at the end of the trial, no significant differences were observed regarding to feed consumption and feed conversion ratio (P 0,05). Overall, feed additives increased carcass yield. Carcass yield of broilers with yeast and yeast+humate supplemented diets were higher as 2,29 % and 2,39 % respectively, compared to control treatment (P 0,01). Percentage weight of liver and length of intestine were not affected by dietary treatments (P 0,05). In conclusion, supplementing yeast (Saccharomyces cerevisiae) into the diets of broiler, either alone or in combination with humate can be used as performance enhancer feed additive instead of antibiotic growth promoter.
