better to add potassium iodide at the rate of one-third of an ounce 

 per 100 pounds of mineral mixture. 



Q. Did you ever feed any of this condensed buttermilk? 



A. Yes, we have done a Httle work with that. Two years ago 

 we did some work with condensed buttermilk, as well as a number 

 of specially prepared feeds. We fed corn and tankage in one lot 

 on rape ; in another lot corn and tankage and buttermilk on rape. 

 It didn't pay to feed the buttermilk in that case, due to the increased 

 cost. Condensed buttermilk costs more than tankage. For fat- 

 tening hogs it is more expensive than tankage. 



O. What do you feed your sows farrowing in the winter time 

 so as to retain their milk? 



A. We have had good luck in feeding oats, corn, tankage and 

 salt — one to two pounds of ground oats per sow per day, plus corn 

 (self -fed), plus tarkage (self -fed), plus a mineral mixture. 



Q. How would wood ashes and salt and lime do? Would coal 

 cinders be as good as wood ashes? 



A. I think that is fine. I think it would be an advantage to 

 feed that mixture. Wood ashes are all right, but coal ashes and 

 cinders are not as good. \A^e had one lot last summer where some 

 holes had been filled with coal cinders. The pigs started eating 

 these cinders and immediately went ofif feed. Their coats were 

 rough, they looked unhealthy, and their dung was hard and black. 

 After moving this group of pigs to a new lot where there were no 

 cinders, they immediately commenced to do better. 



Q. Have you ever tried sand and gravel? 



A. No. Some of our lots are of sand and gravel, but we have 

 never done any real experimental work with sand or gravel. 



Q. Did you notice any difference in the droppings ? 



A. A little bit, yes. 



O. Have you had any experience in ringing your hogs with 

 the Stewart hog ringer? 



A. No, sir ; we don't ring any of our fattening hogs. 



Q. Do you feed them minerals enough to keep them from root- 

 ing up the pastures? 



A. We never had much trouble with them where we have fed 

 a good ration. 



Q. Do the hogs get any benefit from rooting the pasture? 



A. They may get some things out of the dirt — perhaps minerals, 

 etc.
