INVESTIGATION IN ANIMAL NUTRITION 



The calves were fed milk and skim milk the same as the other 

 groups. The amount of grain and hay consumed was a trifle more 

 than was the case with the groups preceding, and they reached the 600- 

 pound weight at about the same time. During the second year they 

 consumed 56.5 pounds more grain and 397.8 pounds more roughage 

 than did Group VI, but they weighed 1,197.5 pounds when they were 

 sent to market, while Group VI weighed only 1,135.7 pounds. 



TABLE X 

 KINDS AND AMOUNTS OF FEED-STUFFS IN THE GRAIN MIXTURE GROUP VII 



It will be seen from Table X that the grains fed during the time the 

 group was in the experiment were a mixture composed of equal parts 

 until the steers weighed approximately 1,000 pounds. The corn was 

 increased and the bran decreased while they were making the 1,100- 

 pound weight. In going from the 1,100- to the 1,200-pound weight 

 the bran was discontinued, the oats and oil meal decreased, and the 

 corn materially increased. 



In the foregoing tables have been given the average weights of the 

 steers at the various stages of growth, the average gain, and the aver- 

 age amounts of the different feed-stuffs consumed, the total amount 

 during the first year, during the second year, and during the two years, 

 for each group. 



SUMMARY OF FEED REQUIREMENTS 



The following tables present similar data based on the average of 

 all the steers in the five groups so as to get more definite data in regard 

 to the normal growth during the various stages and the feed require- 

 ments necessary to convert a calf into a 1,200-pound steer ready for 

 market in approximately two years.
