NITROGENOUS FEEDING STUFFS. IOL 
Ration 1 was fed to cow A during the first and third periods, 
and to cows R and L, T during the second or middle period. 
Ration 2 was fed to cow A in the middle period, and to cows R 
and L, T in the first and third periods. ‘The average rations fed, 
as taken from the report of the experiment, are shown in table 
13, and also the effect of the rations on the quantity of milk, 
butter-fat, and solids, and on the percentages of fat, solids, 
and solids not fat. From this table it will be seen that with 
the narrow ration the daily milk flow ranged from 3 to 5% 
pounds per day greater than with the wide rations, while the 
percentages of fat in the milk ranged from .3 to .5 of a per 
cent. higher when the narrow rations were fed. ‘The propor- 
tion of fat in the total solids was also greater in the case of 
the narrow rations. Cow A for the narrow ration gave 33.4 
per cent. of fat in the total solids, and for the wide ration 
miegaper cent. Cow R- gave 34:3 per cent. for the narrow 
ration and 32.7 per cent. for the wide, while cow L, T gave 
33.1 per cent. for the narrow and 31.6 per cent. for the wide 
ration. 
Experiment at the Pennsylvania State College Experiment 
Station.*— An experiment on the ‘‘Influence of Nutritive 
Ratio Upon the Economy of Milk and Butter Production’’ is 
reported by the Pennsylvania Station. Nine Guernsey and 
grade Guernsey cows, about sixty days past calving, were 
fed through four periods of thirty days each. ‘The rations 
fed were as follows: 
Period 1. Grain mixture of gluten feed and chopped wheat; coarse fodder, 
corn stover. Digestible nutrients consumed daily per cow, 11.58 pounds; 
digestible protein, 1.52 pounds; nutritive ratio, 1:6.6. 
Period 2. For the gluten feed the same quantity of cotton seed meal was 
substituted; the coarse fodder remained unchanged. JDigestible nutrients con- 
sumed daily per cow, 12.87 pounds; digestible protein, 2.62; nutritive ratio, 
1:3.9. 
Period 3. Old process linseed meal was substituted for cotton seed meal. 
Digestible nutrients consumed per cow daily, 12.74 pounds; digestible protein, 
2.38 pounds; nutritive ratio, 1:4.4. 
Period 4. Gluten feed and chopped wheat as in period 1; digestible nutri- 
ents consumed per cow daily, 11.64 pounds; digestible protein, 1.52 pounds; 
nutritive ratio, 1:6.7.
