The average composition of sow's milk as compared 

 with cow's milk is shown in the following table : 



TABLE XXVII. THE COMPOSITION OF Sow's MILK COMPARED 



WITH COW'S MlLK 1 



Sow's milk is shown to be richer in all constituents than 

 cow's milk, particularly in casein and albumin (protein), 

 and ash. The fact that sow's milk contains less water 

 and more protein and ash, largely explains why pigs 

 make larger and more economical gains to a unit of milk 

 and weight than do calves.
