Figure 1. Effect of dietary globin supplementation on body weight (g) at 1, 10, 25 and 35 days of age (MJ/kg) in male and female broiler chickens (mean ± SEM). Note: continuous line represents Globin group and dotted line represents control group; capital letters mean significant effect (p < .050) of sex (S) and/or diet (D), lowercase letters mean statistical tendency (p < .100) of sex (s) and/or diet (d) between control and Globin groups.
