1 Three bought and seven 2-year-olds dropped back from the 1907 group. 



2 One died. 



3 One butchered. 



Of the calves included in this record, 86 were selected at birth, 

 28 yearlings from 1907 were on hand on September 1, 1908, when 

 the records were started, and 3 were purchased, making a total of 

 117 calves for the five years. Out of the 86 selected, 18 were dropped 

 out before they were 1 year old. Eleven of these were pure-bred 

 bulls. Any of these bulls that were not sold before the age of 6 

 months were separated from the heifers in the feeding- pen, and 

 after June 1 a separate record was kept of them. Of the 7 heifers, 

 1 died and the other 6 were discarded and sold. 



Including the 3 yearlings that were purchased and the 28 in the 

 1907 group, there were 99 of the 117 to enter the second record year. 

 Of these 99, the 1911 group of 17 dropped out because records are 

 not yet available, 3 bulls of the 1907 group were sold, 5 discarded 

 heifers were sold, and 1 died. Thus, of the 117 calves, 73 heifers 

 were raised during the five years. 



By means of Tables II to VII, inclusive, the problem of the cost 

 of production is illustrated by complete records of one group of 

 calves from birth in September, 1909, up to the time they entered 

 the herd at 2 years of age in September, 1911. The quantity of each 

 feed consumed was obtained by actual weighing, the prices shown 

 in Tables III and VI being the local prices of feeds at the farm, as 

 reported at the end of each month. This gives a more accurate feed 

 cost than would be obtained by the use of a yearly average price, as 

 several of the more expensive feeds vary in price from month to 

 month. 



The labor shown in these tables represents the actual number of 

 hours of man labor and horse labor expended in caring for the calves 

 and has been obtained from the daily labor-report sheets of all 

 workmen on the farm. 



The cost rate for man labor is 12 cents per hour for the period 

 covered by the records herein presented. The man rate is obtained
