436 Feeds and Feeding. 



These findings coincide with those obtained when feeding grain 

 to steers on pasture. (555) Prom all the evidence at hand -we 

 may conclude that where pastures are luxuriant there are no 

 profits from feeding cows grain; where there is not ample feed the 

 increased milk returns will certainly compensate for the grain or 

 green forage fed. The possible residual effect of feeding cows on 

 pasture, as pointed out by Eoberts, is important and should not 

 be overlooked. Where pastures are short, unless green forage 

 or grain is fed to cows the milk flow will decrease, and later, 

 should the pastures revive, it will be found almost impossible to 

 bring the milk yield back to the normal. The increase in value 

 of the droppings from grain-fed cows should also be considered, 

 and wUl often prove the turning point in favor of a reasonable 

 use of grain, especially kinds rich in fertilizing elements.
