Grain Cart

A diagram of circular travel, 

 gins and ends at the feed work 

 for the next feeding. 



silage cart completes the task except 

 in very large herds where two or more 

 cart loads of silage are needed for one 

 feeding. Even in such cases, the 

 travel of each cart may be in a circle. 

 Arrangements for circular travel 



Note that the labor on this task be- 

 center. The grain cart is in position 



add to and support the effective- 

 ness of good work centers, and well 

 designed and well located work cen- 

 ters enable the operator to take great- 

 er advantage of circular travel effi- 

 ciencies. 



V Milking 



Milking, washing and care of milk- 

 ing equipment, and the care of the 

 milk house usually require over half 

 the total man hours spent on daily 

 chores on cows during the winter. In 

 the pasture season this accounts for 

 about 80 per cent of the total. 



Milking 



The milking phase of this study has 

 been reported in Experiment Station 

 Circulars 76 and 80 and so only a few 

 summary comments on efficient milk- 

 ing will be made in this bulletin. Over 

 a period of time, the herd should be 



selected on the basis of good milking 

 characteristics so that all cows will 

 be milked quickly by machine and 

 without hand stripping. On a few 

 farms studied, from 10 to 20 per cent 

 of the cows were milked by hand. On 

 others, a few cows required over 10 

 minutes of machine milking. Good 

 milking characteristics should be one 

 of the major qualifications in select- 

 ing animals for the herd. If all ani- 

 mals in the herd can be machine 

 milked in 4 minutes or less, the oper- 

 ator can carry on the task of milking 

 efficiently.
