ELEVENTH ANNUAL YEAR BOOK— PART VII 353 



yourself, I do not believe it is well for you to do so unless you have 

 gone through a course of training. I do not want you to understand 

 that I want to create any worke for the veterinarians but the work 

 should be done accurately and you can only do that with a corps of 

 trained men. Illinois and Nebraska are furnishing this free of 

 charge and I understand that Iowa has not done so and I am very 

 much surprised that it is not taking care of its hog industry by ap- 

 propriating sufficient money to do this. It should be done by the 

 state and done thoroughly. If hog cholera appears in a certain 

 portion of your county that herd should be immediately quaran- 

 tined. You should not have any fear that it is going to reduce 

 the price of your hogs. It is simply to keep the other farmers 

 away. 



Dr. Peters in taking up the subject assigned to him, "Preserva- 

 tion of Health in the- Herd," presented it as follows: 



"This question of taking care of the hog is one of my hobbies. We 

 have many diseases that we should take care of and prevent. One of the 

 diseases that you should be careful of and one that is spreading through- 

 out the country to an alarming extent i's that of internal parasites in 

 hogs. That disease among hogs has increased to such an alarming ex- 

 tent that the United States government just about a year ago put a man 

 on for the inspection of hog lungs. Ten years ago we were practically 

 free from that trouble. Our herds are beginning to be more and more in- 

 fested and it is due to the fact that we have not given it enough atten- 

 tion. There are very few breeders in the country who use the precau- 

 tion to quarantine against parasites, or when they buy hogs and put 

 them on their farms to see if they are infested with parasites. I think 

 you should use the same precaution as you do against cholera. The 

 up-to-date man will keep them in quarantine for some time. Let me ex- 

 plain why. The parasite passes through with the faecal matter and 

 passes along the water troughs and feed troughs and is taken up again 

 with the food and the animals become re-infested. The eggs of these 

 parasites pass out by the hundred and it takes but a short time for an 

 entire herd to become infested with this disease. 



Now, what can you use? You can use salt and ashes in equal portion, 

 added to air slacked lime and one-fifth copper sulphate, and you will 

 have a very good powder. This powder should be kept before hogs all 

 the time. It should be kept in a self feeder. It is one of the best condi- 

 tion powders. If hogs are badly infested it is best to give coal tar creo- 

 sote or a weak solution of carbolic acid. Give a one per cent solution of 

 carbolic acid, that is one part of carbolic acid to ninety-nine parts of 

 water, an ounce on an empty stomach, or two parts of coal tar to ninety- 

 eight parts of water on an empty stomach. It is just strong enough when 

 the animal drinks it in a thin slop to kill the worm and in from five to 

 six hours the worms pass out.
