Extract

Sodium bentonite (SB) has been widely used in poultry industry as agent that binds mycotoxine, moisture and ammonia. SB supplementation has generally been used in animal diets for reasons other than the nutrients they supply. 3% SB in cattle rations reported no significant influence on rate of gain, feed efficiency or hepatic vitamin A and carotene retention (Erwin, Elam and Dyer, 1957). Adding 2% of SB resulted in an improved egg production of 11% in laying hens. SB improves feed efficiency, laying frequency, shell quality and egg size and also reduce moisture of the excreta of Leghorn hens (Quisenberry and Bradley, 1964). This experiment was conducted to determine the effect of SB and a synthetic pigment containing lucantin® yellow and xanthin on performance and egg quality of laying hens.
