of the ration, the remainder being made up of such feeding- 

 stuffs as ground oats, wheat middhngs, and bran with a 

 Httle tankage. Blue grass, clover, or alfalfa pasture makes 

 a good supplement to corn. 



For breeding ewes, corn should not make up more than 

 50 per cent of the concentrated portion of the ration. Even 

 less than this usually will give better results. A mixture 

 of such feedingstuffs as oats, bran, or linseed meal should 

 make up the remainder of the concentrates of the ration. 



For Milk Cows. — Inasmuch as the milk cow requires large 

 amounts of protein and mineral matter for milk production, 

 the ration should be correspondingly rich in these nutrients. 

 Consequently, corn ordinarily should not make up more than 

 50 per cent of the concentrates, even when fed with ni- 

 trogenous roughages. The remainder of the concentrates 

 should consist of a mixture of several of such feedingstuffs 

 as oats, gluten feed, linseed oil meal, cottonseed meal, 

 and bran. When fed with a non-nitrogenous roughage, not 

 over one-fourth or one-third of the concentrates should 

 consist of corn. Corn usually is fed to milk cows in the 

 form of ground corn, or corn and cob meal, which is the 

 entire ear, coarsely ground. 



For Work Horses. — It was thought formerly that corn 

 was not a proper feed for work horses, oats being preferable. 

 However, it was found by Carmichael at the Ohio Experi- 

 ment Station ^ that when mixed hay was fed to mature 

 geldings at general farm work, ear corn was as efficient, 

 pound for pound, as oats. Moreover, the use of corn was 

 more economical. At the Missouri Experiment Station,^ 

 Trowbridge found that mature mules doing farm work were
