COMPARATIVE VALUE OF CATTLE FOODS. 



Comparing concentrated foods with coarse feeds, one 

 pound of the former may be considered a food unit; the 

 quantity of grass eaten by one cow at pasture during one 

 day is assumed equivalent to 12 to 13 food units during 

 the early part of the summer, and to 4 food units in the 

 iate fall, 10 units being considered an average figure. 



The following quantities of different feeding stuffs are 

 considered approximately equivalent, as determined by 

 European, largely Danish, feeding experience (Schroll): 



I lb. concentrated feed (cereals, mill refuse-feeds, oil meals, 

 etc.) = 2I to 3 lbs. of good meadow hay = 4 lbs. of poorer 

 quality hay = 10 lbs. rutabagas = \2\ lbs. turnips = 6 lbs. 

 potatoes = 10 lbs. green fodder = 6 lbs. buttermilk = 6 lbs. 

 skim-milk = 12 lbs. whey = i lb. new milk. (See table on 

 p. 19a, also Wis. Exp. Sta., Circ. 37.)
