III. FATTENING STEERS ON SUMMER PASTURE, 
MISSISSIPPI, 1915. 
The cooperative experiments in fattening cattle on pastures in the 
South were discontinued in Alabama after the test of 1913 and trans- 
ferred to Mississippi, where the work was continued in cooperation 
with the Mississippi Experiment Station. The present experiment 
was conducted on the farm of Ben Walker at Abbott, Clay County, 
Miss., who furnished the cattle, feeds, and pastures. 
The soil and pasture grasses are very similar to those of Sumter 
County, Ala., where the previous work was conducted. Clay County, 
Miss., is in the so-called black-prairie section, the soils of which 
carry a good supply of lime, and produce alfalfa, clovers, grasses, 
and. forage crops in abundance. The land, however, is less rolling 
than that in Sumter County, Ala. N. F. Hansen was -employed by 
the bureau to take personal charge of the cattle in the experiments 
and to keep records of the work. 
OBJECTS AND PLAN OF THE WORK. 
The objects of this test were to obtain additional information and 
data concerning the fattening of steers on summer pasture in the 
South. The same general plan was followed as in the Alabama ex- 
periments. The steers were placed on pasture in the spring and fat- 
tened for early fall market. Owing to the high price of corn at 
Abbott in the spring of 1915 only two lots were used. 
Forty steers were divided into 2 lots of 20 each and fed as follows : 
Lot 1, 20 steers, pasture alone; lot 2, 20 steers, pasture and cotton- 
DESCRIPTION OF CATTLE USED. 
The 40 steers in this experiment were ordinary natives of mixed 
and inferior breeding. Jersey blood predominated in all but a few, 
which showed evidences of Angus and Shorthorn blood. They had 
been wintered on cottonseed meal, cottonseed hulls, and corn silage, 
and were in good condition when the experiment began, averaging 
678 pounds. 
CHARACTER AND PRICES OF FEEDS USED. 
The cottonseed cake which w T as fed to the steers of lot 2 was of 
high quality, analyzing 43 per cent crude protein, and cost $29.60 a 
ton delivered at the farm. 
The pastures were practically equal in size and in the area of 
grazing furnished for each lot. The grasses making up these pas-
