experiment, 78 pounds. On the other hand, two calves that weighed 

 within three pounds of each other at birth weighed exactly the 

 same at the end of six months. None of the calves in Lot III 

 gained over a pound per day. The calf that produced the poorest 

 gain weighed 9.8 pounds above the average for the lot at birth. 

 The average daily gain for all calves receiving the Blatchford's Calf 

 Meal was .73 pound, equivalent to 132.86 pounds for the period of 

 one hundred eighty-two days. 



The average gain in body weight was rather uniform for all 

 calves in Lot III during the first five weeks. After the tenth week, 

 a larger increase in gain occurred and continued until the end of the 

 experiment. The largest gain was made between the twenty-third 

 and twenty-sixth weeks and the smallest gain was made during the 

 first five weeks. The largest average weekly gain was 8.6 pounds, 

 made during the twenty-third week, and the minimum weekly gain 

 was .9 pound, made during the fourth week. The largest weekly gain 

 made by any individual calf in Lot III was 20 pounds, produced 

 during the fourteenth week. The average maximum weekly gain 

 was 13.3 pounds. The lowest maximum gain, made by any one of 

 the calves in this lot, was two pounds. Nine of the ten calves that 

 entered this experiment lost weight one or more times. Five main- 

 tained a standard weight one or more times and there was no calf 

 in the lot that had a constant gain throughout the experiment. The 

 total loss in weight for all calves receiving the Blatchford's Calf 

 Meal was eighty-six pounds or an average of 2.86 pounds during 

 the thirty weeks that losses occurred. The maximum loss for any 

 of the ten calves was six pounds, occurring four times during the 

 experiment. Nineteen of the losses occurred before the fourteenth 

 week, the largest number occurring during the third and fourth 

 weeks. A uniform weight was maintained during eleven weeks and 

 all but one occurred before the fifteenth week. The weekly average 

 gain made the week previous to the week that the losses occurred 

 was 3.1 pounds, and the gain made the week subsequent was 2.2 

 pounds. 



COST OF RATION RECEIVED BY LOT III. The cost per pound gain 

 varied with the rate of gain in four instances. The average for the 

 lot was 13.18 cents per pound gain. The calf that made the best 

 gain increased in weight 238 pounds at a cost of 8.47 cents per 

 pound, and the poorest calf gained in weight, 82 pounds at a cost 

 of 26.42 cents per pound gain. The average cost of the ten calves 

 in Lot III for the entire period was $17.44. The most expensive 

 calf cost $21.67 an d ranks lowest from the standpoint of total gain. 

 The most economically produced calf cost $14.75 and stands first 

 from the standpoint of total gain. Based on percentage terms, the 

 calf that made the most satisfactory gains cost 46.9 per cent, more 

 during the first six months of its life than the calf that made the 

 most satisfactory gains. The best individual gained 30.4 per cent.
