The vetch hay certainly proved itself to be a good food, yet 

 there can be little doubt but that it would show to g-reater 

 advantage in combination with foods of a wider nutritive ratio, 

 since i : 4.7 is narrower than common experience has shown 

 to be most profitable.

Whenever there was a change from mixed and oat hay to 

 the mixed hay alone, there was an increase in milk yield, and 

 when the changes were from mixed hay to mixed and oat hay, 

 there was a loss ; so it would seem that the mixed hay (timothy 

 and clover) gave better results than did oat hay, although in 

 one instance (Frost, Jr., period 2) there was a gain from a 

 change from mixed and oat hay to the oat hay alone.
