Now, the next point that I would make is, that in making up a 

 grain mixture we get down to an actual method of work. If that 

 cow is to be of much profit, you want to get that energy as cheap as 

 possible. We take one hundred pounds of protein, as a basis, and to 

 this we add the amount of cottonseed meal you think should be used ; 

 then the amount of gluten feed; then add this up and divide the 

 possible protein into the possible energy. If it comes out right 

 you get a mixture from that standpoint. If not, you can add to it 

 until the sum total of the protein divided into the sum total of the 

 energy gives he right total, and you can work according to this rule, 

 no matter whether you mix twenty-five pounds, or fifty pounds, or 

 one hundred pounds, or two hundred pounds, or three hundred pounds 

 you will find it simplifies wonderfully the mixing of the rations. 



Another thing that our bulletin will contain is totals in which 

 we have dropped the decimals. Now, if you will take the trouble to 

 compare you will see that cottonseed meal has 84.23 therms of 

 energy, and 10.27-28 of protein. Now I have figured that in making 

 mixtures of this kind, it will simplify matters to drop the decimal, and 

 use only the whole numbers, the small amount contained in the deci- 

 mal will not matter. Again I am recommending that we use one 

 hundred pounds value instead of fifty or twenty-five pound values; 

 however, you will find a table in which I have given the protein and 

 ejQergy in connection with twenty-five, one hundred, two hundred, 



and three hundred pounds you can make up almost any kind of a 

 total and figure the amount of protein. Now to give you a sample 

 list, which I have figured up here:
