The cost of a pound of the several mixtures is Hkely to vary 

 from 1.4 to 1.6 cents. It is beheved that the above selections 

 are more economical on the basis of their content of nutritive 

 material than most of the sugar feeds and other proprietary 

 mixtures. 



In general it may be said that the amount of grain to be fed 

 daily depends (a) upon the size of the cow, (b) daily milk yield 

 and (c) the local market value of the milk. The richer the 

 milk, the more food is required to produce a given amount; 

 and vice versa. 



Six to 7 pounds of the above mixtures is a fair average amount 

 for cows weighing 800 to 900 pounds, which are yielding 10 

 quarts of 4 to 5 per cent milk. For every 2 quarts of milk 

 yielded in excess of this amount the grain ration may be in- 

 creased by 1 pound. 



7. Rations for Young Stock. 



Young dairy stock may receive 1 peck or more of silage 

 daily, depending upon their size, in addition to what hay, corn 

 stover or other coarse fodder they will eat clean; or the entire 

 roughage may consist of hay. Ten to 15 pounds of roots daily 

 in cases where silage is not available will prove appetizing and 

 helpful. Grass and clover rowen form a very desirable feed 

 for growing animals. In addition to the above, it is usually 

 advisable to feed from 1 to 3 pounds daily of a grain mixture 

 reasonably rich in protein and ash. ^ Any of the above mix- 

 tures will prove satisfactory. The writer has found mixtures 

 by weight of | wheat bran and ^ flour middlings; or J bran, 

 f corn meal and J flour middlings; or ^ bran, | corn meal and 

 I ground oats quite satisfactory. A ration composed of late- 

 cut hay and corn meal would not be desirable, it lacking both 

 flesh and bone forming material (protein and ash). 



Several months before the heifer freshens it is well, if cir- 

 cumstances permit, to increase the grain ration to 5 or 6 pounds 

 per day in order to get her used to grain and to encourage a 

 large future milk flow. 



The feeder will do well to bear the following in mind: — 



1. Late-cut hay is noticeably less nutritious than early-cut. 



' If the roughage consists largely of grass or clover rowen, 2 pounds daily of a mixture of 

 bran and corn meal, or even of corn meal alone, will prove satisfactory.
