until you know the roughage. If feeding corn silage and alfalfa 

 hay, the grain ration is very simple. 



Q. — All the silage you want and alfalfa, how much grain 



75 to 85? 



A. — Good quality alfalfa, I would feed enough to get the 

 protein, 75 to 80, you want to feed a variety. I would feed 

 some mixed grain. 



Q. — Not very much corn. 



A. — Yes, I would some if heavy on alfalfa, so much protein 

 there. 



Q. — How's corn, oats and clover hay for a cow? 



A. — Very good feed. 



Q. — What will a silo cost to hold 10 acres of silage, approx- 

 imately ? 



A. — A silo for 10 acres of silage will be 150 tons probably. 

 It would depend on how it is built. For 150 tons 18 feet in 

 diameter and 36 feet deep. Built with boards going round 

 and plastered with cement cost $300. If a country where you 

 can have gravel and crushed stone it will last a very long time 

 and then you have a permanent silo with a perfectly rigid wall 

 and one that will not let the air in. 



Q. — How many cubic feet of silage is required to a ton ? 



A. — That will depend on the proportion of the solids. Sil- 

 age in a 30-foot silo will average 42 pounds all the way up. The 

 corn has to be cut at a certain time. It must ripen. Silage 

 wants y 2 cubic foot at the bottom more than at the top. 



Mr. Newman : — They couldn't afford to cut corn stalks. If 

 they wanted to keep 10 or 12 cows, wouldn't they have to grow 

 clover for the soil ?•
