¹ n = 8.

²CON, control; OAFe, orally administrated ferrous sulfate; VA, orally administrated vitamin A; OAFe +VA, orally administrated ferrous sulfate and vitamin A.

³The relative length is the length of the small intestine divided by the final body weight.

⁴The relative weight is the weight of the small intestine divided by the final body weight.

^a–dValues in the same row with different superscript letters are significantly different (P < 0.05).
