induce a relative increase In the milk 

 flow. One pound af meal for 4 lbs. of 

 milk is liberal feeding; one pound 

 of meal to three pounds of milk, to 

 leave a profit, necessitates selling 

 milk at a higher price than the aver- 

 age farmer may hope for. In this 

 connection it may be observed that 

 the quality, or composition of the 

 meal ration is usually an important 

 factor, affecting the milk yield. It 

 is exceedingly important to remem- 

 ber that palatability in the meal, as 

 well as the roughage, is an influence 

 that is not infrequently underesti- 

 mated. Variety in meals fed is ad- 

 visable, but variety should mean a 

 blending of meals, not a substitution 



of one for another at frequent Inter- 

 vals. To illustrate, it is much better 

 to feed a mixture of bran, oats, bar- 

 ley, oil-meal, gluten, cotton-seed 

 meal, etc., than to feed any one of 

 them for a time, to be subsequently 

 replaced by some other. 



Generally speaking, the meal ra- 

 tion for dairy cows should be rich in 

 protein, palatable, easily digested and 

 fairly finely ground, and blended to 

 suit the roughage ration with which 

 It Is fed. Meals vary greatly as to 

 composition and effect upon the di- 

 gestive organs of the cattle. While 

 some are laxative, some are consti- 

 pating in effect, and while some 

 seem to stimulate the appetite, others 

 have the opposite tendency.
