Although we can feed the animals at any time, many cattle owners do not give it during pregnancy but must give it in the dry period and if you want to stop, then stop it 25 to 20 days before the calving, otherwise, the mineral mixture will be milky. And for the whole year, for the heifer, include only 30 grams to 50 grams in the feed, if you keep giving it, the animal will remain healthy and on more milk.
