Abstract
Corn silage treated with 1% ground limestone was compared with regular corn silage in the ration for lactating dairy cows. There were no significant differences in gross chemical make-up of the 2 silages, however, the limestone treated silage contained 104 and 80% more acetic and lactic acids respectively than the control silage. No significant changes in the rumen volatile fatty acids were observed. No significant differences were found in dry matter consumption milk yield, milk fat percent or body weight of the cows consuming the silages.
