Although an attempt was made to separate the cows into practi- 
cally equal groups from the standpoint of milk production, the 
quantity of milk produced by the different cows varied considerably, 
and this affected the results. Cow No. 3 in lot 1 produced twice as 
much milk as either of the other cows, and this made the difference 
in the milk produced in the alfalfa period and the Sudan grass period 
proportionately great. Since the alfalfa was fed earlier in the lacta- 
tion period of this cow, the large yield of milk resulted in a disadvan- 
tage to the Sudan grass. Notwithstanding this fact, the cows pro- 
duced 97.8 per cent as much milk on Sudan grass as on the alfalfa 
hay, though the Sudan grass hay was coarse and poorly cured, while 
the alfalfa hay was first-class. 
Testimonials of hundreds of farmers who have fed Sudan grass hay 
to all classes of live stock confirm the results of these more or less 
definite experiments, indicating the high value of Sudan grass hay as 
a roughage for work animals, stock cattle, and dairy cows. The con- 
sensus of these reports from farmers is that cattle, horses, and sheep 
all relish Sudan grass hay and eat it with no derangement of the 
digestive processes and with good results when measured in gains of 
flesh and ability to work or to produce milk. 
Experts in feeding live stock claim that Sudan grass gives the best 
results only when fed in connection with other forage. It is not 
well adapted to use as the sole roughage in rationing any kind of 
animals. 
PASTURE. 
Sudan grass is perhaps most important as a hay grass, but it is 
used more and more widely as a summer pasture. A number of 
tests, more or less well arranged, have been made in pasturing Sudan 
grass at the different agricultural experiment stations throughout the 
United States. These have been described briefly in Farmers’ 
Bulletin 1126, copies of which may be obtained free, on request, 
from the Division of Publications, United States Department of 
Agriculture. 
At the experiment farm at Dodge City, Kans. , Sudan erass furnished 
abundant pasturage at the rate of one milk cow per acre for a grazing 
period of 125 days, and the cows made a daily average of 3.2 pounds 
more milk per cow on the Sudan grass than on native grasses. At 
the Chillicothe (Tex.) substation, horses, mules, and cows all showed 
a decided preference for Sudan grass over millet and Amber sorgo. 
At the Arizona experiment farm, near Prescott, Sudan grass main- 
tained 20 sheep to the acre continuously for 100 days. No urigation 
was given the grass during this period, yet the sheep fattened per- 
ceptibly and did much better than those grazing on Amber sorgo. 
At the California Agricultural Experiment Station, Davis, Calif. (14, 
pp- 215-216), Sudan grass seeded on silt loam maintained approxi-
