THE SOW 235 



Sows which Eat their Pigs. — Occasionally a sow will be 

 found which, will eat her pigs. It is claimed by 'some that the 

 tendency to eat their young is sometimes caused by allowing 

 sows to eat the afterbirth. As a precautionary measure, the 

 afterbirth should be promptly removed from the pen. There 

 is little doubt that the trouble is generally caused by a fevered 

 condition in the sow, often induced by injudicious feeding be- 

 fore farrowing, or even after farrowing. A remedy that has 

 been suggested is to feed the sow salt pork, but the danger is 

 that once the sow has eaten her jjigs she acquires the habit and 

 is likely to do it again. Unless she is a very valuable sow, it 

 is safer not to give her a second opportunity, but to turn her 

 into the feed lot and fatten her for the butcher.
