pounds of liquid. The lowest amount of whole milk fed during the 

 first sixteen weeks was during the seventh week, at which time, 

 one and one-half pounds of whole milk were consumed per day. 

 The daily requirements of whole milk increased after this time 

 until the tenth week, at which time the calves were consuming 4.32 

 pounds per day. It was again reduced gradually and discontinued 

 after the nineteenth week. During the last three weeks of the test, 

 a small amount of whole milk was again added. There were four 

 consecutive weeks during the entire period that milk was not fed 

 to some of the calves in this lot. 



The milk portion of the ration received by the calves in Lot 

 III was 2.46 pounds per head for the period of one hundred eighty- 

 two days, equivalent to 447.72 pounds, or 52.06 gallons, for the ex- 

 perimental period. The variation in the daily amount consumed by 

 the various individuals was five pounds as the maximum and i.oi 

 pounds as the minimum. The calf that required the maximum 

 amount of whole milk consumed 910 pounds, or 50.8 per cent, more 

 milk than that required for the average of the lot. The calf that 

 received i.oi pounds of whole milk per day consumed 183.8 pounds 

 or 263.9 pounds less than the average of the lot. Three of the eight 

 calves required less than two pounds of whole milk per day ; three 

 less than three pounds per day; one. three and one-half pounds 

 per day and one. five pounds per day. The calf that consumed 

 the maximum amount of whole milk made the poorest gains, 

 averaging but .45 pound per day and the calf that consumed 

 the smallest amount of whole milk produced the largest gains, 

 making an average daily gain of .95 pound. The amount of 

 water consumed per day was 7.67 pounds. The variation between 

 individual calves in this particular was rather marked, due to the 

 fact that it was necessary to substitute such a large amount of whole 

 milk in certain instances. Practically, 3.1 times as much water was 

 consumed as whole milk. The average age at which the calves be- 

 gan to consume water was T.8 weeks. 



The calf meal was fed to a portion of the lot. during the first 

 week, although the lot averaged 1.7 weeks of age as the date the 

 calf meal was first fed. The amount consumed varied from .26 

 pound during the second week, to 1.4 pounds during the twenty-third 

 week. The amount consumed was rather irregular during the 

 course of the experiment; slightly over a pound per day was con- 

 sumed during the fifth, sixth and seventh weeks; during the eighth, 

 ninth, eleventh, thirteenth and fourteenth weeks, slightly less than 

 one pound of calf meal per day was consumed; after the fifteenth 

 week, the amount was gradually increased until the twenty-third 

 week, after which time it was reduced to. approximately, 1.25 

 pounds per day. The average amount of calf meal consumed per 

 day during the period was T.O/ pounds or 17.12 ounces. The max- 

 imum amount required by any individual calf was T.2 pounds, or
