Hours of Man Labor per Cow 



These are based on estimates by each operator as to the average 

 time he spent doing chores, liauling milk, and performing other labor 

 involved in the care of his cows. A compilation of these amounts re- 

 sulted in an average figure of 161.6 hours i)er cow per farm. In Table 

 76 the total man labor averaged 157.7 hours i)er cow — a somewhat 

 smaller number because on the larger farms less time was required 

 per cow than on the smaller ones. That this figure exceeds the average 

 of 150 as allotted by man work units (Table 27) for grade cows may 

 be accounted for by the presence of some purebred cattle on these 

 farms and the fact that several operators retailed a part or all of 

 their milk.
