Abbreviations: CF = Control formula, EF1 = Experimental formula 1, EF2 = Experimental formula 2; * Values are mean ± SEM (n). No significant differences (p > 0.05); ** Mode of delivery was significantly higher for EF1 versus CF or EF2 (p = 0.013); ‡ Males: CF > EF2 (p = 0.0402; CF = 50.9 ± 0.4 > EF2 = 49.6 ± 0.4).
