Subacute Ruminal Acidosis and Evaluation of Blood Gas Analysis in Dairy Cow

Table 2

Mean values ($\pm$SD) of haematological parameters in dairy cows of Groups A, B, and C, each composed of 72 dairy cows. Significant differences between group C and the other two groups are indicated by ${}^{*}$ (vs group A, $P<.05$) and ${}^{●}$ (vs group B, $\mathrm{\hspace{0.17em}\hspace{0.17em}}P<.001$).
