Dr. Wolf gives an illustration of the standard lor a 

 milch cow, by saying (hat '}() Ibs. of young clover hay 

 will keep a cow in good milk; and that this contains oi' 

 dry organic substance, 23 Ibs., of which is digestible 1 al- 

 buminoids 3.21, carbohydrates 11. 28, .and fat 0.(>3. This 

 is .71 Ib. albuminoids more, and .22 11). of carbohydrates 

 less, with .13 Ib. of fat more, than the standard. Then In- 

 takes the richest and best meadow hay, of which 30 Ibs. 

 contains of organic substance 23.2 Ibs., having digestible 

 albuminoids 2.49 Ibs., carbohydrates 12.75 Ibs., and fat 

 42 Ib. This is almost exactly the feeding standard. 



As will have been seen by what has preceded, the 

 German standard ration for a milch cow is 24 Ibs. of dry 

 organic substance, containing 2.50 Ibs. nitrogenous food. 

 and 12.90 Ibs. of carbonaceous food. To secure this, Dr. 

 Wolff recommends for every 1,000 Ibs of live weight : 

 12 Ibs. average meadow hay. 

 6 " oat straw. 

 20 " mangolds. 

 25 " brewers' grain. 

 2 " cotton seed cake. 



Prof. S. W. Johnson's ration for the same purpose is: 

 20 Ibs. corn fodder. 



5 " iye straw. 



6 " malt sprouts. 



2 " cotton seed meal. 



The following milk rations are recommended by Prof. 

 E. W. Stewart :
