Supplementing Milo-Soy Layer Diets with Selenium

Four graded levels of selenium up to 1 ppm were added to milo-soy diets and fed to laying hens during a 6-month period. The basal diet contained 15.2% protein, 3056 Calories of metabolizable energy per kg and 0.4 ppm selenium on a calculated basis. Each treatment was replicated four times with 12 hens in 16 inch cages for a total of 48 hens per treatment
