ruin, while the latter would yield profit if market conditions were any 

 where near right. Group IV received more animal nutrients and less 

 plant nutrients than Group III in growing from the 100-pound to the 

 200-pound weight. The time of change from animal to plant nutri- 

 ment is the critical period with the young. The calves were also 

 brought to a larger ration than those in Group III in growing from 100 

 to 200 pounds weight, but it is quite likely that the difference in results 

 was chiefly brought about by the better- trained eye of the feeder of 

 Group IV.

Table IV gives the amount of the different grains fed to Group IV 

 during the two years. During the first year, the grain mixture was two 

 parts each of ground corn and barley, four parts of bran, and three 

 parts of linseed meal. During the second year, barley gradually in- 

 creased in price, and in the 1,100-pound period a gradual change to 

 ground oats was made. 



The latter part of April, 1910, when Group IV had attained a 

 weight of 500 pounds, another circular letter was sent to farmers who 

 had previously furnished calves of satisfactory breeding and type, re- 

 questing the shipment during May of new-born beef-bred calves. Judg- 

 ing from the rate at which the calves came, it appeared that farmers 

 were eager to dispose of their beef-bred calves without question as to 

 price, since before the shipments could be stopped 64 calves arrived 

 in Minneapolis by express. A few days after the arrival of the calves, 

 when their digestive systems contained a normal amount of food, they 

 were weighed. The average weight was 79 pounds. On the morning 

 of May 29, 45 calves were selected for the experiment and the others 

 were sold for veal when in proper condition. Those selected averaged 

 101 pounds in weight.
