Feed complete mineral mixes with higher potassium and sodium levels only to the milking cows. If fed to dry cows, these mineral mixes may cause increased udder edema. Buffers can partially offset the effects of low fiber rations. Frequently buffers are mixed in equal parts of magnesium oxide, limestone and sodium bicarbonate. Feed the mixture according to production.
Cows tend to eat more feed in the cool of the night than during the day.
Adjust the feeding rate so less is fed during the day and more at night, thus reducing feed spoilage and improving dry matter intake. Make sure the feed area is lighted. The TMR does not dry out as quickly as when water is added to it. If wet brewers' grains are used, have them delivered frequently. Keep feeding areas clean and free from spoiled and moldy feeds.
