FEEDS AND THEIR VALUES QI 



OATS AND PEAS 



Among the farm crops adapted to dairying there 

 are few more profitable than oats and peas combined. 

 The peas should, on most ground, be put in by plow, 

 disk-harrow, or seeder, at least four inches deep, 

 and should precede the putting in of the oats by 

 about a week. There should be about one and one- 

 half bushels of peas and two bushels of oats per acre. 

 They make an excellent forage crop when needed 

 in July and August. Crops can be put in a week 

 apart for succession forage supply. When not 

 needed for supplemental food in a dry time they 

 may be cut to hay, just as oat straw starts to turn 

 color; or they can be allowed to ripen and can be 

 threshed and ground as a grain food. The peas 

 contain nearly 19 per cent, of protein and 53 per 

 cent, of carbohydrates. The straw is good as a 

 roughage for cattle eating silage. 



MANURIAL VALUE OF FEED STUFFS 



This division of feed values as it relates to eco- 

 nomical feeding has not heretofore been considered. 

 If the herd is to be charged with the value of the 

 feeds, it must also be credited with what it returns 

 to the soil in fertilizing values. As a rule, the cow 

 uses up in the process of producing milk, butter, and 

 beef, and in keeping up her animal heat, about 20 

 per cent, of the potash, phosphoric acid, and nitro- 

 gen contained in her food. The remainder is manure. 



A large amount in value of this product is con- 

 tained in the liquid excretion. This is the most 

 readily available for plant growth. On many farms 

 all, or a great part, of this is wasted. The total
