30 DAIRYING 



the evening milking is longer than before the morning milking 

 as it is claimed that exercise of the cow during the day has a 

 tendency to make the udder secrete somewhat richer milk than is 

 the case during a quiet night period. 



183. There is no doubt that the act of milking excites 

 the activities of the milk glands, and consequently the greater the 

 number of milkings in a day, the more milk will be obtained, but 

 whether or not the increased amount obtained by three or four 

 milkings each day and the price received will cover the expense 

 of time and labor in doing this extra milking, and caring for the 

 milk three or four times instead of twice a day, is a question that 

 each man must decide for himself. 



F. Milking One Teat at a Time. 



184. It has been shown by a number of trials that when the 

 milk from each teat is kept separate there is a difference in the 

 amount and in the richness of the milk obtained from the different 

 teats. The average of four trials made with one cow milked one 

 teat at a time gave the following figures.* 



Milk Ibs. Fat % 



(A) Right fore teat 2.17 3.76 



(B) Right hind teat .2.15 3.93 



(C) Left hind teat 2.95 4.26 



(D) Left fore teat 2.05 3.69 



9.32 3.92 



It was found, however, during these trials that the difference 

 was not always the same, but the amount and the richness of the 

 milk obtained from each teat was influenced by the order in which 

 the teats were milked, and by changing the order at each of four 

 milkings the following variations in the milk from each teat was 

 noted :
