that cotton seed bulls contained 3
pounds of crude protein in 100 pounds
26 per cent of this Z pounds is digesti-
Bile. This gives 98-100 of a pound OF
digestible protein, this is the unit for
the nutritive ratio of cotton seed nuIls.
The crude fibre in the hulls is AZ $500
pounds and SO per cent of it is digesti-
BILE, this will gives22 27~100 pounds of
digestible crudei fibre. The fat pres
ent is 54-100 pounds and 81 per cent
is digestible, this figures to 42-10O of q
pound of d1gestible fat which is to be
multiplied by 9 ] as described above.
this makes it figure up to l 5-l0G
pounds. The non-nitrogen extractive
matter in cotton seed hulls is Al z
pounds, 40 per cent of this is digestible.
which upon multiplication gives IL
40 pounds of digestible non-nitrogen-
Gus extractive matter. Upon adding
together the digestible percentages ri

result will be 40 2-l00 pounds. AS we
have only 98-100 of a pound of digesti
bic protein, the nutritive ratio will be

to cotton seed meal which is too expeu

ratio to use 7lone.
Cotton seed meal in hundred pounds
contains 1S-100 pounds of a crude fibre
Of which 26 per cent is digestible
There is II 74-100 pounds of fat Of whicl

Here we have two materials widely diff
terlng In their nutritiYe ratios. cotton

seed meal ]: l $40, very rough food
and very rich one. If one desires tC
feed an animal for the best results in q
given case, whether it is for work, fat
tening or the furnishing of milk, the
nutrltlve ratio is secured for such an
animal under the given conditions.
The nutritive ratio for the mich COW
for example is /: 40. BY calculation
we find that it will take about 100
pounds of hulls and % pounds of cotton
seed meal to produce this ration OF il
even numbers. and for a food rich
enough for most purposes 1 pound of
meal to every 5 pounds of hulls
Some animals may not be willing at
first to touch the hulls containing thi,;
small amount of meal, bnt they are
readily taught to eat them by adding
the meal very literally at first and thetl
gradually decreasing the amount until
the desired proportion is reached, when
they continue to eat the mixture with
avidity and relish.
The use of cotton seed hulls for fat
tening cattle and for mich cows has
been very extensively practiced for
some time in the Mississippi Valley.
