Mean ± SE values with dissimilar alphabets in a column vary significantly (p < 0.05). FCR, feed conversion ratio. Chromium, arsenic, and vitamin E were given @ 270, 50, and 150 mg.kg−1, respectively, while bentonite was administered @ 5%. G1 = Group 1: Control (negative); G2 = Group 2: Chromium; G3 = Group 3: Arsenic; G4 = Group 4: Vitamin E; G5 = Group 5: Bentonite; G6 = Group 6: Chromium + Arsenic; G7 = Group 7: Chromium + Arsenic + Vitamin E; G8 = Group 8: Chromium + Arsenic + Bentonite; and G9 = Group 9: Chromium + Arsenic + Vitamin + Bentonite.
