Fig. 1From: Effect of in ovo folic acid injection on hepatic IGF2 expression and embryo growth of broilersEffects of in ovo folic acid injection on IGF2 mRNA expression in the liver of new-born chickens. Numerical values (0, 50, 100, 150 μg) in X-axis mean the amount of folic acid which was injected into eggs. Data were presented as means ± SEM (n = 6). Bars with different letters are significantly different (P < 0.05). The P values for linear and quadratic regression analysis were 0.324 and 0.225, respectivelyBack to article page
