Abstract

This experiment was conducted to investigate the efficacy of different levels of biotin on broilers performances, protein and fat apparent digestibility and carcass characteristics. The study was conducted at University of Duhok, College of agriculture, Animal House Complex. A total of 160-day-old Ross 308 randomly assigned to 4 treatments with four replicate pens per treatment and 10 birds each pen.  Treatments were control diet without additive and three levels of biotins which are biotin 1, biotin 2 and biotin 3 at concentrations 1000, 1500 and 2000 mg/10L of drinking water respectively during the whole rising period. The results showed that different levels of biotin increased body weight gain (WG) and biotin2 and biotin 3 improved Feed conversion ratio (FCR) compared to control group at day 35. Adding different levels of biotin in drinking water had significantly higher protein digestibility over non-treated group. In conclusion, adding biotin to broiler water had positive effect on WG, FCR and protein digestibility
