Extract

corn silage use in large industrial farm for dairy cows but it is low in protein. ammonia and urea has been used for increase the N content of corn silage. Also it seems are they can increase milk production in cows. Ammonia can increase true protein of silage and it has mould killed properties in silage and can delay the growth of mould and yeast in opened silages. Ammonia can increase butyric acid content in silage so increase milk fat in dairy cows.
