Fig. 3From: Relative significances of pH and substrate starch level to roles of Streptococcus bovis S1 in rumen acidosisEffects of soluble starch concentrations and pH on LDH, PFL, α-AMY and CCPA gene expressions. Soluble starch concentrations are 1 g/L, 3 g/L and 9 g/L; Columns and represent the pH at 6.5 and 5.5; Values are means (n = 3) with their standard errors represented by vertical bars. Significant differences are indicated among three starch concentrations with different superscripts (a, b, c) (P < 0.05). The expression of four genes at pH 5.5 were significantly higher than pH 6.5 (P < 0.05)Back to article page
