No. 7. DEPARTMENT OF AGRICULTURE. 207 



versity saj at an institute that sulphur properly fed to a dairy cow 

 was all right. I was not in the business at that time or I would 

 like to have asked him a question, so that I might have learned 

 more about what he meant; but I have been using sulphur in the 

 feed, commencing along perhaps in December, feeding half an ounce 

 to a cow, sometimes increasing it a little, and I have kept them 

 off. Whether it has been to the injury of the cow in any way, I 

 don't know. If anybody else has tried the experiment, I would like 

 to know it. 



PROF. MAIRS: I know that sulphur fed to animals in the spring 

 will prevent them from being lousy; whether the sulphur kills the 

 lice, I don't know. It probably comes out with the perspiration 

 and, is disagreeable to the lice, but as far as feed is concerned, I 

 don't believe that changing the feed itself has any effect upon the 

 lice, and I know that fat cattle in the best of condition will get lousy 

 if they are in warm stables, and the surroundings are right above. 

 [ never heard of animals being injured by being fed sulphur, and 

 I know a great many men who feed sulphur to their animals as soon 

 as it begins to get warm in February. 



A Member: I would ask the question whether they ever use the 

 brush on the animals? We have been brushing our cows for some 

 time and find it advantageous. I think the best plan is to purify 

 your stables the same as you would with a hen-house. 



MR. HOWDEN: It has been our custom every year to whitewash 

 the inside of our stables, but still they get lice in the spring after it 

 becomes warm.
