FEEDING STANDARDS 457 



5. FEEDING STANDARDS 



The feeding standards for the various classes of farm 

 animals are taken from Mentzel & Lengerke's Landw. 

 Kalender for 1899. They are intended to apply to ani- 

 mals of average size fed under normal conditions. They 

 are not to be regarded as feeding recipes, but are to be 

 varied according to circumstances. Small animals should 

 receive proportionately more food than large ones; milch 

 cows in proportion to the quantity and richness of the 

 milk; growing and fattening animals according to the 

 rapidity of increase desired; work animals according to 

 the severity of labor, and individual animals according 

 to their peculiar needs. 



The quantity of "dry substance" will vary according 

 to the digestibility of the ration, with no harm. It is 

 important to maintain the necessary quantity of diges- 

 tible dry substance. This should be somewhat more if 

 the ration has a larger proportion of coarse materials 

 than when it is mostly grain. The nutritive ratio may 

 widely vary according to the availability and price of 

 feeding-stuffs. The method of calculating a standard 

 ration is explained in Chapter XIX.
