Q. That would also be true of linseed? 



A. Yes. 



Q. Has the station ever tried any feeding of different amounts 

 of silage in the winter time to the cattle that were on pasture in 

 the summer time, to see what effect there would be on the cattle? 



A. No; we haven't had the land so that we could do that. We 

 have a new farm now, ar.d we hope to do some summer feeding of 

 cattle in the future. One winter we tried different amounts of 

 corn and silage, one of silage and no corn, and others a half feed- 

 ing of silage. 



Q. And then did you pasture them? 



A. No, we didn't; they were finished and we sold them. 



Q. Did you ever try feeding cattle with a full feed of shelled 

 corn and salt allowed self-fed? 



A. In some experiments a comparison was made between salt 

 and no salt, several years ago. 



Q. What was the result? 



A. There is an advantage in feeding salt. There is an in- 

 crease in gain. Steers ate less than half an ounce of salt a day, 

 yet it increased the gain and decreased the cost of 100 pounds of 

 gain. 



Q. You spoke of feeding bone-meal. Where do you get it? 



A. It can be bought from any of the packers, and it costs about 

 $75 a ton. Wt used Armour's finely ground bone-meal in our tests. 

 In some of our tests we have used spent bone-black. That is the 

 part of the bone-meal that has been used in the sugar refineries and 

 is "worn out." You can buy it for around $30 per ton. There 

 is some question as to which is the best — bone-meal or spent bone- 

 black. It may be as good as bone-meal. It can be bought from 

 the Clinton Corn Syrup Refining Company, at Clinton, Iowa. 



Q. There is a mineral that is claimed to increase the number of 

 pigs farrowed, and I have been told that Ames recommended it. 



A. There is a mineral mixture put out by a company, the formula 

 of which was taken from the fairly complete mineral mixture that 

 we have used. In two years' work we have found that lime, salt 

 and bone is apparently practically as good as that mixture. Neither 

 one increased the number of pigs farrowed per sow. Lime, salt and 

 bone cost about 3 cents per pound to mix. The fairly complete mix- 

 ture you can buy from one company for 5 cents in 200 or 500- 

 pound lots, I believe. So far we have had good results from lime, 

 salt and bone. In the case of pregnant sows, it might be a little
