 other home-grown farm feeds will take care of the 

 carbohydrate materials — ^the starches, the fibers, the 

 sugars — and the fat. Your problem is to get pro- 

 tein, and if you desire to have your cows do their 

 best, hence increase your profits, you will obtain 

 the feed or feeds that gives you the protein at the 

 cheapest cost per pound of digestible material. 

 Otherwise you will pay dear for your whistle.
