 Economic data in Table 3 are presented in two ways:

 (1) Assuming a cost of $20 per 100 pounds going into the feedlot, cost of cattle
 and feed are deducted from actual sale price of carcasses.

 (2) Feed costs plus an additional assumed cost of $0.10 per head daily are
 deducted from actual sale price and the differences are divided by the
 initial weights of the calves to obtain initial value per 100 pounds (at
 the beginning of the trial).

From data presented in Table 3, it can be seed that returns above costs of cattle and feed
are small; this, of course, includes no charges for other expenses. When $0.10 per head
daily is deducted for expenses other than feed, the various groups of calves would have had
to be purchased at "break even" prices ranging from $16.78 to $20.63 per 100 pounds
delivered to the feedlot. Lot 33 (1/2 Hereford-1/4 Brahman-1/4 Angus) and Lot 37 (1/2 Short-
horn-1/2 Brahman), with higher carcass grades, faster gains, and higher sale prices, had
higher initial values per 100 pounds.

 All the crossbred and the Santa Gertrudis calves originated in fluke-infested areas,
and 50 of these 70 cattle had live flukes in their livers at slaughter. Following were the
number of livers in each group that passed veterinary inspection and the number condemned:

 Number
 Number Condemned
 Lot Passed (flukes)
 31 2 8
 32 1 9
 33 0 10
 34 0 10
 35 8 2
 36 7 3
 37 2 8
 Total 20 50

The Lot 38 Herefords were not from a fluke area, and all their livers passed veterinary
inspection. Feedlot gains and carcass characteristics of fluke-infested and non-infested
cattle were similar; however, in the fluke-infested cattle, loss of the liver itself was
significant from a monetary standpoint.
