BULLETIN 1024, TJ. S. DEPARTMENT OF AGRICULTURE. 



To determine which ration should be used in a particular feeding 

 operation, it is suggested that the feeder apply local prices to the 

 average amounts of the feeds consumed per cow. as given in Tables 

 3 and 8. 



COSTS OF RATIONS AND OF CALVES PRODUCED. 



Because of the unusually high percentage of calves dropped, which 

 was due to the practice of substituting cows that were bred for any 

 which failed to breed in time for a spring calf the following year, the 

 cost per cow kept is only slightly less than the cost per calf raised, as 

 Table 9 shows. It is considered that the cost of labor, the bull 

 charges, and other expenses are balanced by the manure produced.

 for each calf raised to weaning age.
