42 MONTANA EXPERIMENT STATION 



The feeding experiment carried on during the winter of 1906 

 1907, was divided into two periods first, while the steers were going 

 on full feed and. second, while on full feed. In both periods ihe gain 

 was proportionate to the amount of grain fed and "his was true in all 

 experiments when the quality of the nay was poor. In this experi- 

 ment nearly 10 per cent of the hay was weighed back as waste. It 

 was over ripe when cut and was poorly cured. In the second per- 

 iod whin on full feed the proportion of gain to grain was not so pro- 

 nounced as in the first period. Lot i, in the first period made .9 

 pounds of gain per lu'ad per day on 2.5 pounds of grain and 23 

 pounds of hay; while the steers in Lot IV. made 1.9 pounds of gain 

 on 4.6 pounds of grain and 23 pounds of hay, but in the second per- 

 iod Lot I. made 1.7 pounds of gain per head per day on 3.0 pounds 

 of grain and 23.7 pounds of clover hay; while the steers of Lot IV. 

 made 2.2 pounds gain on 10 pounds of grain and 21 pounds of hay. 

 In the first penod doubling the grain doubled the gain, while in the 

 second period trebling the amount of grain fed increased the gain 

 only 30 per cent. The cost of production decreased with the in- 

 crease of grain in the first period, when a small amount of grain was 

 fed. but increased in the second period with a small amount of 

 grain fed. AYhen a large amount of grain was fed, trebling the 

 amount of the grain ration more than doubled the cost of produc- 

 tion.
