This experiment was conducted to investigate the effects of selenium (Se) sources and levels on growth performance, nutrient digestibility and Se retention in growing-finishing pigs. A total of 56 crossbred pigs ([Landrace×Yorkshire]×Large White) with average 28.5±0.2 kg BW were allotted to 7 treatments on the basis of sex and weight in two replicates and four pigs per pen. A 2×3 factorial arra...
