PREVENTING WORMS.

The common round-worms of pigs ordinarily occur in the small intestines, but are frequently found invading the adjacent organs, particularly the bile ducts of the liver. It is practically impossible to breed pigs free from worms in quarters which have been used for that purpose for years, because the soil is polluted with millions of eggs passed by animals of previous years, each egg containing a live embryo ready to launch its attack when ingested by the young pig. Thus it is important that all farrow. in£ pens be cither located on eheap ground, or that they be thoroughly scrubbed with boiling water and lye. Ordinary antiseptics do no good in so far as destroying worm larvae is concerned. Pigs born into a clean environment and kept free from contact with old* infected pens escape the various hazards accompanying worm infestation. It is desirable" to move them from these clean pens into open fields or pastures wherever this is possible, and to keep them away from infected quarters until they are at least four or five months of age. A good deal can be accomplished by ordinary sanitary measures in removing the filth which accumulates in pig pens and in the use of sanitary wallows.
