COLOSTRUM 



The fluid the cow yields directly after calving 

 is known as colostrum, which differs essentially in 

 composition from normal milk, and is usually con- 

 sidered unfit for human food. Colostrum, or 

 biestings, as it is sometimes called, contains so 

 much albumen, sometimes as high as fifteen per 

 cent, that when heated it becomes perfectly thick 

 and looks like a rich custard, for this new milk is 

 also high in color, and has a rather strong odor. 



The milk gradually loses its colostrum char- 

 acter, and in from five to ten days after the cow 

 has freshened, is generally normal.
