possibility. What are those qualities which are indicative of a 

 good dairy cow? First, the large udder. Here is where the 

 milk is made. The milk is made from the blood. But we must 

 remember that the udder should be large, but not fleshy. How 

 determine that? By milking out the udder and notice whether 

 still distended or loose and flabby. The next important item is 

 the milk veins. This is called the milk vein, but it is raelly the 

 blood vein. That takes the blood from the udder and draws it 

 back into the heart and lungs. This must necessarily be large. 

 If a cow must give a good quantity of milk, there must be good 

 storage capacity. A large pipe system is necessary for a good 

 cow, because when you milk, you draw largely upon the heart, 

 and the larger the pipe system, the better your cow is. A good 

 big heart is necessary to pump a circulation ; a good big lung is 

 necessary to purify a large amount of blood. If that is the case 

 you want a cow that is wide in front. Not at all. We will com- 

 pare this with a racehorse. A racehorse expends more energy 

 in trotting a mile in two minutes. I will illustrate this point 

 better. I will run and you walk as fast as you can. Not one 

 of you could keep up the pace if you started with a full capacity 

 at the end of a mile. But you can walk all day and not get tired. 

 It shows that the energy required is in a confirmation where the 

 chest and heart are similar to that of a racehorse, because it takes 

 energy to make a milk in two minutes, and considerable energy. 

 The lung activity and the lung well must be thin, and the heart 

 must be big. Consequetly you get confirmation with a large 

 digestive capacity. 



I am showing you a cow that is a Holland Fresian. You 

 may say I am partial. That is not the case at all. I am going 

 to show you other cows where the same confirmation is preserved. 

 I will say the average cow produces 135 lbs. per year of butter 

 fat. This is a question of profit and if a man is in this business, 

 he ought to make some profit. You cannot afford to have a cow 

 making 3 cents tallow by putting meat on her, when you can get 

 30 cents for your butter.
