Il8 ELEMENTARY TREATISE ON STOCK FEEDS AND FEEDING 



The liays from grasses, dry fodders, straws, and cane molasses 

 would probably be considered as carbohydrate feeds although it 

 must be remembered that they do not contain as much protein 

 as the feeds included in Class V. 



This table may be found useful in the selection of feeds. 

 Classes I and II are especially rich in protein and may be classed 

 as protein feeds. Classes III and IV may be termed protein and 

 carbohydrate feeds. Class V includes the carbohydrate feeds. 



Conversion Factors. — Some products are used for fertilizer 

 and feed, and when sold may be guaranteed to contain only 

 nitrogen or ammonia. The following factors will be useful in 

 obtaining equivalents of nitrogen, ammonia and protein: 



One per cent, nitrogen = 1.2154 per cent, ammonia = 6.25 per cent, 

 protein. 



One per cent, ammonia = .823 per cent, nitrogen = 5.14 per cent, 

 protein. 

 One per cent, protein = .16 per cent, nitrogen = .1945 per cen^. ammonia.

Example. — Cotton-seed meal, carrying 6.58 per cent, of nitrogen, is 

 equivalent to cotton-seed meal containing 6.58 X I-2I54 or 8.00 per cent, 

 ammonia and 6.58 X 6.25 or 41.12 per cent, protein. A feed containing 15 

 per cent, protein is equivalent to a feed containing 15 X -1945 or 2.92 per 

 cent, ammonia and 15 X -iS or 2.40 per cent, nitrogen. 



Condimental Feeds. — ^There are a great many of these feeds 

 sold in this country. They arie made up of mixtures of sulphur, 

 salt, saltpeter, Epsom salts, Glauber's salts, sodium bicarbonate, 

 fenugreek seeds, fennel seeds, ginger, turmeric, gentian powder, 

 charcoal, red and black peppers, ground bone, Venetian red, anise, 

 oyster shells and similar products, generally with some feed as 

 a basis, in varying proportions. These feeds generally carry
