FIFTIETH ANNUAL CONVENTION 105 



tein varies from 12.23 per cent in colostrum to 3.24 per cent 

 in milk at the seventeenth milking. It has been noted that 

 the change in composition of milk continues for several 

 weeks after calving, it being, of course, much more gradual 

 after the first eight or ten days following parturition.

Experience in the feeding of calves teaches the im- 

 portance of providing the new-born calf with an adequate 

 supply of colostrum for the first four or five days following 

 birth. In its absence a tablespoonful of castor oil should be 

 given with each feeding for the first two or three days, or 

 until the bowels have functioned properly. 



The Cow That Refuses to Own Her Calf. 



Occasionally, especially with heifers, one may observe 

 the unnatural act of a calving cow refusing to own or care 

 for her new-born calf. No explanation is offered for this 

 strange condition. In such a case it is unwise to attempt to 

 force the calf upon her. The cow may be milked and a 

 small portion of the colostrum fed to the calf artificially. 

 Feedings should be frequent. After the bowels have func- 

 tioned the calf may be shifted to the regular method of 

 hand feeding, receiving unseparated herd milk for the first 

 two or three weeks.
