efficacy of ascorbic acid and butylated hydroxylanisole in amelioration of aflatoxicosis in broiler chickens

the effect of ascorbic acid (aa) and butylated hydroxyanisole (bha) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for aa and bha) in diet containing 1 ppm total aflatoxin (af: 76.45% afb1, 10.52% afb2, 9.89% afg1 and 3.14% afg2). a total of 300 day-old broiler chicks were divided into ten treatment groups (t1=control; t2= t1+1 ppm af; t3= t1+250 ppm aa; t4= t1+500 ppm aa; t5= t2+250 ppm aa; t6= t2+5000 ppm bha; t7= t1+1000 ppm bha; t8= t1+2000 ppm bha; t9= t2+1000 ppm bha; t10= t2+2000 ppm bha). the results showed that inclusion of 1 ppm of total aflatoxin in the diet resulted in a significant decrease in body weight gain (bwg). supplementation of aa or bha to the af contaminated diets increased bwg of broilers (p
