Extract

Selenium (Se) is a dietary trace mineral for poultry. Organic Se such as selenomethionin (SM) increases plasma Se more affectively than inorganic forms such as sodium selenite (SS) (Payne and Southern 2005). Thyroxine 5’-deiodinase-1 (D1) is a selenoenzyme in liver which converts T4 to T3 (main thyroid hormone in poultry) and produces 95% of plasma T3 (Bianco et. al. 2002). This study describes the effects of SM (Biokey® Selen) versus SS on growth performance and plasma level of thyroid hormones by using different levels of dietary energy.
