4-6 pounds below the average weight of the ten calves. By exclud- 

 ing two animals in calculating the average, the extreme weights of 

 the calves in Lot II were 84 and 50 pounds, respectively. Express- 

 ing the variation in weight in terms of percentage, it is noted that 

 the heaviest calf weighed 60.9 per cent, more than the lightest calf, 

 and 42.5 per cent, less than the average for the lot. 



At the end of the experiment, Lot II averaged 244.1 pounds. 

 The lightest calf in this lot weighed 179 pounds less than the heavi- 

 est calf which weighed 120.9 pounds more than the average for 

 the lot. Three individuals in this lot maintained the same relative 

 position at birth and at the end of the test. The failure of such a 

 large number of calves to gain in weight consistently from birth 

 to the age of six months, indicates that the ration which they re- 

 ceived was not especially well adapted to animals of this age. The 

 extreme difference in weight of individual calves at birth was 72 

 pounds, and at the end of the experiment, the difference in weight 

 of the same two calves was 179 pounds. On the other hand, two 

 calves that weighed within one pound at birth, weighed exactly 

 the same at the end of six months. Five of the ten calves in 

 Lot II gained over one pound per head per day. The five indi- 

 viduals that made the best gains were not the heaviest calves in the 

 lot as the birth weights varied from 40 to ,112 pounds. The calf 

 that produced the poorest gain weighed 14.4 pounds above the 

 average for the lot at birth. The average daily gain for all calves 

 receiving the home-mixed calf meal was .95 pound, equivalent to 

 172.9 pounds for the period of one hundred eighty-two days. 



The average gain in body weight was rather irregular. The 

 weekly gain in weight was 5.34 pounds as an average for the first 

 five weeks of the experiment or, approximately one-third of a pound 

 above that made during the next four weeks. After the ninth week, 

 the gains made by seven-day periods were consistent, varying from 

 5.65 pounds to 8.7 pounds. The largest average weekly gain was 

 14.5 pounds, made during the twenty-fifth week and the minimum 

 weekly gain was 2.6 pounds, made during the sixth week. The larg- 

 est weekly gain made by any individual calf in Lot II was 29 

 pounds, produced during the twenty-fifth week. The average 

 maximum weekly gain was' 21 pounds. The lowest maxi- 

 mum weekly gain made by any one of the ten calves was 13 

 pounds. Eight of the ten calves lost weight one or more times, four 

 maintained a standard weight, and one calf gained but two pounds as 

 its minimum performance. The total loss in weight for all calves re- 

 ceiving the home-mixed calf meal was 69 pounds or an average of 

 slightly over four pounds during the sixteen weeks that losses oc- 

 curred. The largest loss took place during the eleventh week and 

 nine of the sixteen losses occurred on or after the thirteenth week. 

 The average gain made the week previous to the week that the losses 

 occurred was 12.3 pounds and the gain made the week subsequent 

 was 9.4 pounds.
