Table I shews, in abbreviated form, the effect of 23 of the best 

 known Jersey sires on the best average butter-fat production of 

 their daughters as compared with the dams of these daughters, 

 when both are put on the same age basis. It appears from this 

 table that about one-half of the bulls in this group got daughters 

 which, on the average, were poorer producers than the dams of 

 these daughters. In some cases the deleterious effect of the bull 

 on the productive quality of the breed was extremely marked. 

 On the other hand, certain of the bulls in this group, notably.
