stover, clover hay, oat hay, and second quality mixed hay which 
went to make up the total coarse fodders of the ration. The better 
grades of hay, such as timothy and red-top were among the most 
expensive feeding stuffs used. When good hay sells at fourteen 
to eighteen dollars per ton it ts generally more profitable to sell 
than to feed to dairy cows. . 
(3.) A liberal proportion of the nitrogenous grain feeds tended 
to lessen the cost of the ration in the majority of cases, while the 
net cost was greatly reduced by their use. The nitrogenous feed- 
ing stuffs like rowen hay, clovers, oats and peas, cotton seed, linseed, 
and gluten meals, should be more largely used in feeding dairy 
stock. | 
(4.) The legumes, such as clovers, peas, soy beans, etc., should 
be more largely grown and more largely used in making up feed- 
ing rations. The larger the proportion of these nitrogenous coarse 
fodders used in the vation, the less will be the quantity of the 
concentrated nitrogenous grain feeds which need to be purchased 
and used. 
(5.) While tt ts impossible to suggest any formula Sor feeding 
that tt would be wise to follow rigidly under the wedely varying 
conditions existing on our dairy farms, yet tt ts better to be guided 
by some general formula or standard than to have no rule for 
guidance. Our studies tend to point more and more to the con- 
clusion that rations should be compounded in accordance with the 
milk flow rather than in accordance with the live weight of the 
animals. If the milk flow is uniform, the feed need not vary 
much for variations of roo to 200 pounds live weight, but wtth 
an increase tn the milk flow the size of the ration should be larger, 
and especially the protein should be increased both in total quantity 
and relatively, in order to meet the increased demands on the 
system of the antmal.*
