88 MANUFACTURED FOODS FOR AGRICULTURAL STOCK. 
except the hay, in the foregoing list of ordinary foods, which 
cost only about one fourth or one fifth as much. 
The following is the result of an analysis in the Rotham- 
sted laboratory, by Mr. Segelcke, of one of these foods. A 
practical trial of the same iood will be noticed further on.

Independently of the slight colouring with turmeric, and 
flavouring with cumin, anise, or other of the stimulating 
and carminative seeds used in cattle-medicine, which these 
foods frequently exhibit, the constituents as here stated 
could be supplied by a mixture of barley-meal with some of 
the leguminous seeds enumerated, and oilcake or linseed. 
Such a mixture, according to the prices quoted, could be 
prepared for about one fourth the price of the manufactured 
cattle-food. 
These foods are recommended to be used in comparatively 
small proportion to the total food consumed. The animals 
have, therefore, still to rely for the bulk of their nourish¬ 
ment upon ordinary food; and it is stated that, with the 
use of these manufactured foods, the quantity of corn may 
be reduced to about one half; and that coarse and compara¬ 
tively innutritious matters, such as bran and chopped straw, 
will, by the admixture, be rendered palatable and nutritious. 
Now, bran and chopped straw contain a large proportion 
of woody fibre, which, though required for bulk by the 
ruminant animals, passes through their bodies in a finely- 
divided state, but otherwise almost unchanged. More or 
less of the soluble matters are extracted from such food 
during its passage; but no evidence has been brought for¬ 
ward to show that these manufactured foods will so stimu¬ 
late digestion as either to extract more of its already-exist¬ 
ing nutritious matters, or to render the woody fibre itself, of 
the coarse foods mentioned, more directly serviceable to the 
nourishment of the animals. 
All animals require in their daily food a given amount of 
digestible and convertible constituents, such as starch, sugar, 
pectine, gum, oil, nitrogenous compounds, and certain mineral 
matters. The proper amount of some or all of these must
