49^ SWINE IN AMERICA 



A SELF-DIPPIXG DEV^ICE 



Prof. J. H. Shepard of the South Dakota experimeiit 

 station, and a practical breeder of swine on his own ac- 

 count, has devised a means whereby his hogs shall dip 

 themselves. He has found that by having in the hog- 

 lots or pasture a bath tank filled or partly filled with 

 water, in which has been stirred a quart or two of good 

 dip, the hogs will do enough bathing in tliis mixture to 

 keep them free from lice and their skins in the very pink 

 of condition. It seems that the addition of the "dip" 

 does not make the water objectionable to the hog for 

 bathing purposes, and in warm weather time that might 

 otherwise be given to filthy wallows will be spent in 

 this valuable disinfecting mixture. 



He writes the author, saying: "The tanks are eight 

 feet square and ten inches deep, built of two-inch planks, 

 and they are all connected with a large water tank by 

 pipes fitted with valves. I use about one quart of dip to 

 a tank three-fourths full of water. This is renewed 

 about once in two weeks, depending on the weather. The 

 water is supplied as necessary. All that is needed is to 

 open a valve and let it run in. In muddy times it is 

 best to clean out the tank and take a fresh start. This 

 can be done in five minutes with a scoop shovel, I have 

 used Kreso dip with excellent results, and I can say the 

 same of zenoleum. I have noticed when the tanks are 

 first filled with fresh water, and after the dip has been 

 added, that the pigs will keep taking small drinks of the 

 mixture as if they liked it. I have an idea, too, that this 

 helps to keep worms out of my herd. Of course I also 

 have slaked lime and coal ashes where the hogs can help
