SUMMARY. 



1. Short-aged calves that are too young to wean and put on feed 

 in the fall can be fed grain while on pasture the following summer 

 and sold directly off grass or finished in the dry lot. 



2. During both the summer and the winter feeding periods the 

 calves that were fed shelled corn and cottonseed meal made larger but 

 more expensive gains than those fed on cottonseed meal as the sole 

 concentrate. 



3. Gains made during the summer are very much cheaper than 

 those made in the dry lot during the winter. 



4. The grain ration of the calves of lot 1 cost $9.50 and that for 

 lot 2, $16.08 for the summer. 



5. The calves cost $5 per 100 pounds in the spring and the cost in 

 the fall after all feed and pasture was charged against them was 

 $5.02 and $5.73 per hundredweight for lots 1 and 2, respectively. 



6. When on full feed, each calf of lot 1 ate 4^ pounds of cottonseed 

 cake per day: and of lot 2. 3 pounds cottonseed cake and 6 pounds of 

 shelled corn. 



7. The calves were fed 179 days on pasture and 67 days in the dry 

 lot, or a total of 246 days. 



8. The calves of lot 2, which received shelled corn, were much 

 fatter than those of lot 1 when finished and they dressed out 2 per 

 cent more. They also sold for 43 cents more per hundredweight. 



9. Eight pigs following the calves of lot 2 made one pound per 

 head per day gain and returned a pork credit per calf of $2.65. 



10. When the pork credit is considered the calves fed corn re- 

 turned almost the same profit as the calves fed cottonseed meal. 



11. For each calf of lot 2 to make the same profit as lot 1. namely, 

 $10 per head, the corn had to be charged at 77 cents per bushel 

 instead of 80 cents.

VI. GENERAL DISCUSSION OF THE FIVE YEARS' EXPER 



MENTS. 



The prices of the feeds and cattle used varied so much from year 

 to year that the financial statements of the various experiments are 

 not strictly comparable. If cottonseed meal was very cheap one year 

 and comparatively high another year, the financial outcome of the 

 two experiments would be misleading. This is true of all similar 

 experiments, and for this reason experimental data can not be used 

 directly by a feeder where conditions are different from those re- 

 ported in the experiment. 



If the farmer is given certain data as to the average daily gains, 

 the amount of feed required to make 100 pounds of gain, and if he,
