were supplied. The average amount of dry matter consumed by 

 the calves in this lot was 36.03 pounds for each dollar invested in 

 feed. 



The amount of protein required during the first part of the 

 test was .41 pound for each hundred pounds live weight. This re- 

 quirement gradually increased to .527 pound for each hundred 

 pounds live weight during the last week of the test. The increase 

 in protein consumption was gradual and regular from the begin- 

 ning to the end of the test. The protein was largely furnished by 

 the calf meal, approximately 43.8 per cent, of the total amount being 

 secured from this material. Alfalfa hay ranks next, supplying 

 33.37 per cent. ; dry mash, third, furnishing 11.44 per cent. 



The carbohydrates consumed by the calves in Lot III varied be- 

 tween .75 pound per hundred pounds live weight during the second 

 week of the test to 2.12 pounds during the twenty-sixth week. As 

 with the protein, the increase in carbohydrate consumption was grad- 

 ual and regular from the beginning to the end of the test. 



The daily consumption of the various food nutrients is as fol- 

 lows : the total amount of dry matter consumed per head per day 

 was 3.45 pounds;. protein, .687 pound; carbohydrates, 2.37 pounds; 

 and fat, .189 pound.. The nutritive ratio of an average daily ration 

 was i : 4. The daily nutrients required per hundred pounds live 

 weight were as follows: dry matter, 1.7 pounds; protein, .343 

 pound; carbohydrates, 1.18 pounds; and fat, .0944 pound. The ash 

 was supplied largely from one feed, namely, alfalfa hay. The al- 

 falfa hay supplied 52.69 per cent. ; the calf meal, 27.26 per cent. ; 

 and the dry mash, 10.10 per cent, of the ash received by the calves 

 in Lot III. 



GROWTH OF CALVES IN LOT III. The average height of the 

 calves in Lot III at the end of the first thirty-day period was 30.3 

 inches. The height of the different individuals of the lot varied 

 from 26 inches to 34 inches. The rate of growth of the various 

 individuals during the five periods over which it is possible to re- 

 port is as follows: second month, one calf increased two inches 

 in height ; six, one inch and one failed to gain ; the average gain for 

 the period was one inch. During the third period, four calves gained 

 two inches in height, and four one inch ; the average gain for the 

 period was 1.5 inches. The fourth period, one calf gained three 

 inches in height ; four calves two inches, two one inch and one failed 

 to gain; the average gain for the period was 1.6 inches. The fifth 

 period, two calves gained two inches in height and six one inch ; the 

 average gain for the period was 1.3 inches. The sixth period, two 

 gained three inches in height, three two inches, two one inch and 

 one calf failed to gain; the average gain for the period was 1.9 

 inches. The total gain in height was represented by three calves 

 gaining five inches, three eight inches and two nine inches ; the
