SANITATION IN THE HOG LOT 493 



makes the following strong statements (Bulletin No. 74) 

 relative to clipping swine for lice: "It has been known 

 to the intelligent hog breeder that the presence of in- 

 sects on the hog is a very serious matter. It is a fact 

 that very few hogs are free from lice, and that breeders 

 have been accustomed to use various remedies for the 

 destruction of the pest. The favorite seats of lice on 

 the hog are back of the ears, along the neck and under 

 the breast. These vermin are bloodsuckers, and they 

 produce in a short time a very weak, debilitated condition 

 of the animal, making him far more susceptible to other 

 diseases that the animal is heir to. The louse has not 

 been credited with occasioning serious loss, but of late 

 years more attention has been given to this. We have 

 found that the hog louse becomes a more serious enemy 

 when hogs are out of condition. If the accompanying 

 conditions are bad, especially if the pens are excessively 

 dusty, and through the inhalation of an excessive amount 

 of dust there should be a slight pneumonia of the lungs, 

 the animal badly affected with lice will be all the more 

 apt to die. 



"We have found also that where animals affected with 

 cholera were free from lice, there was a much smaller 

 percentage of loss. This has been brought to our atten- 

 tion after examining numerous herds during the last 

 five years. The first rule that we now insist upon when 

 we visit an outbreak of cholera is to examine for lice, 

 and, if present, to thoroughly destroy these vermin. The 

 breeding pens and hog houses are also thoroughly dis- 

 infected. All the bedding that is found in pens and hog 

 houses at time of disinfection is burned. The method
