Diarrhoea caused by irritating germs is a highly infec- 

 tious disease. These germs gain entrance to the body of 

 the pig by way of the digestive tract and navel cord. 

 Infectious diarrhoea is very fatal. 



Preventive measures are the most satisfactory so far 

 known for diarrhoea in pigs. This prevention consists 

 in avoiding conditions that may directly or indirectly 

 cause the disease; in allowing the sow plenty of ex- 

 ercise ; and in feeding her the right kind of ration before 

 farrowing, in order that she may give birth to strong 

 healthy pigs. 



Pigs from a few days to a few weeks old may be treated 

 indirectly by dieting and giving the mother a physic. It 

 is advisable to feed the mother a very light ration, espe- 

 cially if she is a heavy milker. From 2 to 4 ounces of 

 linseed-oil should be given in a drench or with the feed. 

 Older pigs may receive treatment direct. The dose of 

 linseed-oil depends on the age and size of the pigs and 

 will vary from one teaspoonful to one tablespoonful. 

 The following mixture may be given : bicarbonate of 

 soda 4 drams, bismuth subnitrate 2 drams, and salol 

 1 dram. This mixture may be given in gelatin cap- 

 sules, from four to fifteen grain doses twice daily being 

 administered. 



DISEASES OF THE RESPIRATORY ORGANS 



Diseases of the air passages and lungs are common in 

 hogs. This group of diseases may be classified as specific 

 when due to an infection such as the Bacillus suisepti- 

 cus and filterable virus, and non-specific when due to 

 such causes as chilling, irritation from inhaling dust, and 

 un ventilated quarters,
