Can different concentration of chelated and inorganic trace minerals (Zn, Se and Cr) be an effective supplement for better production performance and carcass traits in broilers?

Abstract

Poultry is the fastest growing livestock sector in the developing countries. The global poultry sector is expected to continue to grow, as demand for poultry meat is driven by growing needs, population, rising incomes and urbanization. The present experiment was conducted to investigate the effect of inorganic and chelated trace minerals supplementation on production performance and carcass traits in broilers. A total of 216 broilers randomly divided into twelve groups and each group consisting of 18 broilers in 3 replicates. T1 group was kept as control. T2, T3 and T4 group was supplemented with zinc (40 mg/kg of feed) inorganic, chelated and 50% chelated form respectively. T5, T6 and T7 groups was supplemented with selenium (0.3 mg/kg of feed) from inorganic, chelated and 50% chelated form respectively. T8, T9 and T10 groups was supplemented with chromium (2 mg/kg of feed) from inorganic, chelated form and 50% chelated form respectively. T11 and T12 group was supplemented with combination of all 3 minerals from inorganic and chelated form respectively. Significant difference (p
