The average daily amount of dry matter received by the calves 

 in Lot II was 1.36 pounds during the second week oi; the test. This 

 amount was gradually increased to 1.97 pounds during the fifth 

 week; 3.07 pounds during the ninth week; 4.12 pounds during the 

 thirteenth week; 4.98 pounds during the sixteenth week; 5.92 

 pounds during the twenty-first week and 6.91 pounds during the 

 twenty-sixth week. The amount of. dry matter required increased 

 immediately after the eighteenth week and decreased during 

 the last four weeks of the experiment. The largest increase in dry 

 matter consumption was during the period included between the sixth 

 and nineteenth weeks. During the second week it required 1.68 

 pounds of dry matter for each hundred pounds live weight and dur- 

 ing the twenty-sixth week, 2.87 pounds for each hundred pounds 

 live weight. 



The largest amount of dry matter was supplied by the alfalfa 

 hay, as approximately 48.3 per cent, of the total amount came from 

 this source. The calf meal ranks next as a source of dry matter 

 supplying 28.9 per cent, and the dry mash third, supplying 17.4 

 per cent. The cost of the dry matter in the milk portion of the 

 ration as calculated on a unit basis is as follows: for each dollar 

 invested in calf meal, 44.81 pounds of dry matter were supplied; 

 and for each dollar invested in whole milk, 7.716 pounds of dry 

 matter were supplied. The average amount of dry matter consum- 

 ed by the calves in this lot was 58.44 pounds for each dollar invested 

 in feed. 



The amount of protein required during the first part of the test 

 was .45 pound for each hundred pounds of live weight. This re- 

 quirement gradually increased to .55 pound for each hundred pounds 

 live weight during the last week of the test. The increase in protein 

 consumption was gradual from the beginning to the end of the test. 

 The protein was largely furnished by the calf meal as approximately 

 52 per cent, of the total amount consumed was secured from this 

 material. Alfalfa hay ranks next, supplying 33.4 per cent, and the 

 dry mash stands third, furnishing 9.3 per cent. 



The carbohydrates consumed by the calves in Lot II varied 

 between .79 pound per hundred pounds live weight during the sec- 

 ond week of the test to 2.04 pounds during the twenty-sixth week. 

 As with the protein, the increase in carbohydrate consumption was 

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



The daily consumption of the various food nutrients indicates 

 that an adequate amount was supplied. The total amount of dry 

 matter consumed per head per day was 4.15 pounds; protein, .93 

 pound; carbohydrates, 2.84 pounds; and fat, .16 pound. The nutri- 

 tive ratio of an average daily ration was 1 13.4. The daily nutrients 

 required per hundred pounds live weight are as follows : dry mat- 

 ter, 1.7 pounds; protein, .38 pound; carbohydrates, 1.16 pounds; fat, 

 .067 pound. The ash was supplied, largely, from one feed, namely,
