TABLE 3. AVERAGE DAILY GAIN PER STEER IN POUNDS BY PERIODS AND 

 AVERAGE FOR WHOLE TIME 



TABLE 4. SUMMARY OF TABLE 3 (POUNDS) 



Periods 



Table 3, shows the average daily gain per steer during the periods 

 corresponding to those in Table 1. Owing to the great variation in 

 the weights of steers it has seemed best to summarize these six periods 

 into three in order to study the relative rate and cost of gains. Con- 

 sequently periods 1 and 2, 3 and 4, and 5 and 6 are summarized in 

 Table 4. From this it can be readily seen that lot 2 made the larger 

 gains, but the difference in rate of gain decreases as the feeding period 

 advances. This indicates that the mixed feed fed thru a self-feeder 

 may be especially advantageous for accustoming cattle to a grain 

 ration. It also indicates that the difference in its favor would probably 

 be more marked in the short than in the long feeding period. 



TABLE 5. AVERAGE COST PER POUND OF GAIN BY PERIODS AND AVERAGE 

 FOR THE ENTIRE EXPERIMENT 



(Value of pork produced not credited to steers) 



(Value of pork produced credited to steers) 



Table 5 summarizes the cost of gains. While the data presented 

 here are probably not sufficient to warrant a definite conclusion, it in- 

 dicates that the diminishing efficiency of the feed consumed as the 

 feeding advances was slightly more marked in lot 1 than in lot 2. In 

 the lower part of the table the value of the pork produced was de- 

 ducted from the expense, thus reducing the cost per pound gain of 

 beef. Another point of significance as, shown by Table 5, is the simi- 

 larity in the average cost of gain for the two lots for the entire period.
