2. Summer Feeding Experiments with Milch Cows. 

 July, 1892, to September, 1892. 



[Coarse fodder articles : rowen, green vetch and oats and green corn fodder ; 

 grain feed ; wheat bran, Buffalo gluten feed, cotton-seed meal and new process lin- 

 seed meal.] 



Object of the Experwient. 



This experiment had for its object the studying of the 

 comparative vahie of three distinct fodder rations on the 

 economical production of milk and cream during tlie summer 

 season. 



The first ration consisted of green vetch and oats ad libi- 

 tum,, four pounds of rowen and three pounds each of wheat 

 bran, Buffalo gluten feed and cotton-seed meal. 



The second ration consisted of rowen ad libitum and three 

 pounds each of wheat bran, Buflalo gluten feed and new- 

 process linseed meal. 



The third ration consisted of four pounds of rowen, all the 

 corn fodder the animal could eat, and three pounds each of 

 wheat bran, Bufialo gluten feed and new-process linseed 

 meal. 



The vetch and oats were cut when in bloom, and the corn 

 fodder when the kernels were beginning to glaze. 



Four pounds of rowen were fed daily in connection with 

 the green fodder. The daily consumption of green fodder 

 was governed by the individual appetite of the animals, and 

 usually decreased with the advancing stage of growth of the 

 fodder plant. The feeding of the green crops ceased as soon 

 as they neared maturity, and they were then cut and made 

 into hay, or, in the case of corn fodder, placed in the silo. 



The cows were grades of various description, and the gen- 

 eral management of the experiment was the same as in the 

 one immediately preceding.
