This Feeding experiment indicates that corn meal fed with corn fodder, or corn ensilage, results in the more rapid decrease of milk, and its fat, and solids, than the advance in the period of lactation justifies.
That corn meal fed with sorghum ensilage results in very rapid decrease in milk, and milk fat and solids, and that the combination is not profitable.
That corn meal fed with roots and clover hay is palatable and gives good results, without considering the cost of feeds, that was not normal during the experiment.
