Hydroxy Selenomethionine Can Rescue Broiler Growth Performance and Meat Quality Under Heat Stress Through Enhanced Antioxidative Capacity

Heat stress (HS) brings large economic losses for the poultry industry, as HS leads to significantly impaired growth performance and meat quality in broilers. The overloaded oxidative stress triggered by HS is the main reason for such loss. In this study, 600,000 birds were used to evaluate the effect of hydroxy selenomethionine on overall growth performance and meat quality in commercial broiler farms in Central Thailand under HS conditions during summertime. The results indicated that HS significantly reduced both the growth parameters and most of the meat quality traits. However, OH-SeMet treatment at 0.03 ppm level can effectively eliminate the negative impact of HS hence and improve the profitability of commercial broiler producers
