This table shows that of ioo cows which are bred 78 of 

 them conceive (so called stick) at the first service; 15 of them 

 conceive at the second service ; 4 at the third service ; 1 at the 

 fourth service and from this the number that conceive becomes 

 so small as to be almost negligible. The place in this series at 

 which the dairyman is justified in selling his cow is, of course, 

 a matter for him to decide. It seems doubtful, however, if it 

 would pay to keep a cow beyond the fifth service unless she is 

 of considerable value.
