CONCENTRATED INFORMATION FOR BUSY FARMERS. 



Most of the home grown coarse feeds are high in 

 The Why of carbohydrates, low in protein and comparatively in- 

 Grain digestible. Such feeds, containing a high percent- 



Feeding, age of woody fiber, require considerable more en- 

 ergy for their digestion than do the grains and their 

 by-products. Nearly all of the concentrates are very digestible, have 

 comparatively little fiber, and many are high in protein and low to 

 medium in carbohydrates. The concentrated feeds are used, there- 

 fore, in connection with the home grown coarse feeds, first, to in- 

 crease the total digestible matter ; second, to furnish food that will 

 digest with a minimum expenditure of energy ; and third, to increase 

 the amount of protein in the daily ration. 



An iUustraticDi. Many experiments have demonstrated that a 

 I coo pound cow producing daily 12 quarts of an average quality of 

 milk, needs approximately the following amounts of digestible 

 nutrients : 



Digestible. Protein. Fat. Fiber and Starchy Matter. Total. 



Pounds, 2 to 2.5 .5 13-00 16.00 



Now if the animal were fed daily as much of an extra quality of 

 hay as she could consume, she would receive : 



Digestible. Protein. Fat. Fiber. Starchy Matter. Total. 



Pounds, 1.3 .3 5.4 7.60 14.60 



The ration is deficient both in total nutrients and in protein, for 

 the reason that the hay has comparatively a low digestibility, and 

 lacks protein. If 7 pounds of the hay were replaced by an equal 

 weight of corn meal, the hay and corn meal would furnish : 



Digestible. Protein. Fat. Fiber. Starchy Matter. Total. 



Pounds, 1.4 .47 4.1 10.25 16.22 



The corn meal being very digestible but a one-sided or starchy 

 feed, would sufficiently increase the total digestible nutrients, but not 

 the protein. If four pounds of the corn meal were replaced by two 

 pounds of bran and two pounds of cottonseed meal, the several 

 nutrients would supply : 



Digestible. Protein. Fat. Fiber. Starchy Matter. Total. 



Pounds, 2.17 0.60 4.25 8.83 ^S'^S
