The calf- feeding work of 1916-17 shows most clearly the value of 

 pasture supplemented with a grain ration for fattening calves. The 

 cottonseed-meal-fed calves of lot 1 made 100 pounds of gain in the 

 summer for $5.04, whereas in the winter the same gain in weight cost 

 $9.68. When one-third cottonseed meal and two-thirds shelled corn 

 were fed as the grain ration the calves of lot 2 made gains during the 

 summer at 86.58 and during the winter at SI 2.86 per 100 pounds. 



In Table 30 no account is taken of the pork that would be produced 

 behind the calves receiving corn, and this amount must be calculated 

 and added to the profits for the corn-fed calves. There would be no 

 pork credit for the calves of lot 1, fed cottonseed meal, and a smaller 

 credit for those fed com-and-cob meal than the ones fed shelled corn 

 or broken ear corn. At the present prices of pork, it would be con- 

 servative to add a pork credit of $2 to S3.50 per calf for the calves 

 of lots 2 and 3 for the last three years, depending upon the amount 

 of corn fed to each lot. This amount of profit should be added to 

 the profit shown in the table. 



In Table 29 it is seen that in every year except 1912—13 where corn 

 was fed the cost of the gains was more than where cottonseed meal 

 was fed as the sole concentrate.
