Principles and Practice of Stock Feeding 29 



more and better manure, more profit, some outlay of brains, but no outlay of 

 money. 



Although this case is suppositious, and not always possible to duplicate, 

 yet results similar in kind if not in degree might be attained on thousands 

 of Vermont farms, to the benefit of both land and occupants. 



IV. SUNDRY ECONOMIC CONSIDERATIONS 



1. classification of roughages and concentrates 



Lindsey 1 has classified the cattle fodders and feeds in more common 

 use in a clear manner, basing the scheme upon the relative proportions of 

 digestible protein and of digestible carbohydrates contained. His classifi- 

 cation, somewhat modified and extended, is presented herewith. 



Roughages 



1. Loir in digestible protein, high in digestible carboliydrates. 



Hay, grasses (other than pasture grass), corn silage, fodder and 

 stover, cereal fodders, straws, (45-75 per cent digestible); roots, 

 potatoes, (75-95 per cent digestible). 



2. Medium in digestible protein, high in digestible carbohydrates. 

 Clovers, pasture grass, rowen, oats and peas, barley and peas, leg- 

 umes in general ; all either green, hayed or ensiled, (50-70 

 per cent digestible). 



Concentrates 



1. Low in digestible protein, medium in digestible carbohydrates. 



Oat hulls, cottonseed hulls, cottonseed feed, (40-70 per cent 

 digestible. ) 



2. Low in digestible protein, high in digestible carbohydrates. 



Grains (except peas and beans), cob meal, provenders, corn and oat 

 feeds, barley screenings, wheat screenings, hominy chop, starch 

 feed, (70' 2 -90 per cent digestible). 



3. Medium in digestible protein and carbohydrates. 



Quaker and H. 0. dairy feeds, wheat and rye brans, dried brewers 

 grains, malt sprouts, (62-80 per cent digestible). 



4. Medium in digestible protein and high in digestible carbohydrates. 

 Wheat middlings, mixed (wheat) feed and red-dog flour, gluten 



feeds, Atlas meal, pea meal, (70-87 per cent digestible). 



5. High in digestible protein, medium in digestible carboliydrates. 

 Cottonseed, linseed, flax and gluten meals (74-90 per cent di- 

 gestible.)
