cloths, and strip cups are washed. 

 Each milker head is fully assembled 

 and put in place on hooks. Other 

 equipment is put in place without 

 rinsing. 



Following rinsing with clear water 

 at night, the process of rinsing is re- 

 peated using the detergent solution 

 instead of water the second time. The 

 milker heads are not dismantled. The 

 utensils are put in place,

 experiment in finding the best and 

 quickest routine for doing each task 

 and a sequence that would fit all the 

 tasks together. 



VI Feeding 



The physical task of feeding cows 

 is not identical for all farms due to 

 the differences in combination of 

 types of feed as well as the location 

 of storage of the grain and roughage. 

 While the detailed procedure adopted 

 must be adjusted to the situation on 

 each individual farm, the general pro- 

 gram of simplifying the feeding op- 

 erations is applicable to most farms. 

 Adaptations can be made by each op- 

 erator. 



Approximately two pounds of di- 

 gestible protein and 15 pounds of 

 total digestible units are needed daily 



per cow. These nutrients are usual- 

 ly supplied by some combination of 

 hay, silage, and grain. The combina- 

 tion will vary from farm to farm due 

 to availability of different types of 

 roughage and changes in price rela- 

 tionships of grain and roughage to 

 milk. Hay and silage can be sub- 

 stituted one for the other on the ba- 

 sis of one pound of hay to three of 

 silage. Grain can also be varied 

 within limitations depending on the 

 quality of the roughage, price rela- 

 tionships, and capacity of the cows.
