PRODUCTION OF MILK 



205 



The amount of produce yielded by a good cow 

 is very large, and far exceeds tliat yielded in the 

 same time by a growing or fattening ox. In the 

 following table the constituents in the weekly increase 

 of a fattening ox are compared with the constituents 

 of the milk yielded by a cow. 



* The milk sugar has been calculated into its equivalent in fat, and is here 

 included. 



The quantity of albuminoids and ash constituents 

 in the cow's milk thus always greatly exceeds the 

 quantity yielded by a fattening ox as meat; and in 

 the case of a first-class cow in full milk, the fat and 

 sugar in the milk are also much more than equiva- 

 lent to the largest produce of fat in the ox. 



Notwithstanding the large amount of produce 

 obtained from the cow, the quantity of food required 

 is not correspondingly large. Thus in Wolff's rations, 

 a cow yielding 27j lbs. of milk daily is given 18"2 lbs.
