Live Weight of Animals during the Feeding Periods (pounds). 



Conclusions.— A careful examination of the previously recorded 

 results of our inquiry into the respective particular claims of cotton 

 seed meal, old process linseed meal and gluten meal as constituents 

 of the daily diet of milch cows, leads us to the following statements : 



1. The substitution of three pounds of gluten meal by either 

 three pounds cotton seed meal or three pounds of old process linseed 

 meal, at stated market prices, and under otherwise corresponding 

 circumstances, does not materially aifect the market cost of the daily 

 fodder ration used in our case. The difference in their market price 

 amounts to 0.3 cents in fav<;r of old process linseed meal. Taking 

 the obtainable manurial value into consideration, as far as the three 

 stated grain feed constituents of the daily diet are concerned, three 

 pounds of cotton seed meal are 0.94 cents cheaper than three pounds 

 of gluten meal and 0.22 cents cheaper than three pounds of old pro- 

 cess linseed meal. 



2. The comparative nutritive effect of cotton seed meal, gluten 

 meal and old process linseed meal, as far as their influence on the 

 yield of milk is concerned, in case of otherwise corresponding fodder 

 rations depends evidently in a controlling degree on two distinctly 

 different circumstances ; namely, the individual disposition and con- 

 stitution of the animal on trial, and on the particular kind of coarse 

 fodder constituent of the daily diet. In case of rowen as coarse 

 fodder constituent, cotton seed meal leads in five out of six cases 

 both gluten meal or old process linseed meal ; while in case mixed 

 ensilage or corn stover served as coarse feed the gluten meal com- 

 petes well with cotton seed meal. Old process linseed meal has only 

 been tested with rowen on the present occasion ; it stands but little 

 behind the gluten nieal. 



3. The density of the milk in case of the same cow varies but 

 little during the experiment ; the notable changes are apparently in a 

 controlling degree due to the particular condition and individuality 

 of the cow engaged in the trial.
