132 THE COW IN HEALTH AND DISEASE 



usually best to wait for about 48 hours in most 

 breeds of cattle before removing the after- 

 birth, but in Jersey cattle it is good policy to 

 wait many times for about 73 hours. It is 

 practically safe to wait in any cow for at least 

 24 hours. 



Many people are of the opinion that there 

 is some way of preventing this retention, and 

 that there is also some medical agents that 

 can be given that will cause the cow to pass 

 them, but there is none as far as we have ever 

 been able to learn. 



Remember that early intervention is to be 

 recommended if you are sure that the cow has 

 retained afterbirth, that veterinary help will 

 be of little account unless it is secured early. 

 Better be safe first than to take any chances 

 of losing a good and valuable cow.
