Professor T. L. Haecker, the best authority in the world on 

 feeding dairy cows, finds a cow needs for a maintenance ration 

 per hundred pounds, 07 protean, 07 carbohydrates, 01 fat. These 

 decimals multiplied by the weight of the cow will give you the 

 ration required to maintain a cow. He also found that the 

 higher percentage of fat in the milk the more feed was required 

 to produce a pound of milk; thus in milk of 3.5 per cent fat, 

 .042 protien, .21 carbohydrates, .016 fat in 4 per cent milk. 



.046 protein, .23 carbohydrates, .018 fat in 4.5 per cent milk. 



.049 proten, .25 carbohydrates, .019 fat in 5 per cent milk. 



.051 protein, .27 carbohydrates, .021 fat in 5 per cent milk. 

 The table which I have here and which can be easily obtain- 

 ed by anyone gives the digestible number of pounds of the diff- 

 erent nutriments in one hundred pounds of many kinds of both 

 concentrates and roughage. Knowing the weight of a cow in 

 normal condition, a ration that will maintain this condition 

 should be given. Then knowing the maximum quantity of milk 

 the cow will give per day and the per cent of fat it contains, a 

 ration can be figured out which will produce this milk in the 

 most economical manner. Palatibility must also be taken into 

 consideration. A feed may be ever so scientifically compound- 

 ed, but unless it is palatable and relished by the cows it will not 

 produce results. 



To the average dairyman, we will say that for good sized 

 cows forty pounds of ensilage given in two feeds, night and 

 morning, and all the clover hay they will eat and one pound of 

 ground feed composed of corn, oats and bran, equal parts by 

 weight for each three or three and one-half pounds of milk, 

 feeding the cow up to her limit on that rate will give profitable 

 results. Cottonseed meal or other concentrates can be substi- 

 tuted for the oats and bran feeding the grain mixture on the 

 ensilage. In this way a cow will be fed all she will need to do 

 her best and give the greatest amount of milk at the least cost. 

 Dairymen consult your own interest. Read all the best dairy 

 papers, dairy bulletins, study the cow, her likes and dislikes, 

 study the feed question and aim to produce as much of it as 

 is possible on the farm, buying as little as is necessary to properly
