Middlesex for an Invention of "IMPROVEMENTS IN FOOD FOR CATTLE AND
OTHER ANIMALS” communicated to him from abroad by Sofus Ove Kjær of
Ribe in the Kingdom of Denmark Candidatus pharmacia
PROVISIONAL SPECIFICATION left by the said Peter Jensen at the Office
of the Commissioners of Patents on the 3rd April 1883.
PETER JENSEN, of 33 Chancery Lane in the County of Middlesex
"IMPROVE-
MENTS IN FOOD FOR CATTLE AND OTHER ANIMALS." (A communication to me
from abroad by Sofus Ove Kjær of Ribe in the Kingdom of Denmark, candidatus
pharmacise),
A principal object of this Invention is to utilize the blood from slaughter houses
for the production of food for animals; heretofore such blood has either been
allowed to run to waste or has at most been utilized for manure.
Food prepared according to this invention is exceedingly nutritious and whole-
some and is eaten with avidity by all sorts of animals and even by cows and
horses which otherwise have a strong dislike to the smell of blood. The food is
made into a kind of bread.
For the purpose of this invention the blood is first deprived of its fibrine, for
which purpose it immediately on issuing from the slaughtered animal is exposed
to agitation and cooling; for this purpose it may advantageously be treated in an
apparatus like a churn and having a cooling appliance at the bottom. To each
100 pounds of blood so treated are then added the albumen from about 25 pounds
of blood; this albumen is or may be produced by thioning the blood with water,
boiling, addition of acetic acid, and filtration, the albumen being deposited on the
filter.
The blood compound is then mixed with meal of any kind of grain and with
straw or hay, crushed flax seed, the finest quantity of bone meal, and salt. The
straw or hay serves partly to make up bulk, partly because it is of great
nutrimental value to animals and partly to give the bread the required lightness

page_text: and porosity, as no fermenting material is used lest the bread should not keep so
well. The bone meal is important for the developement and preservation of the
bones of the animal, and the salt serves to make the bread keep and to make it
tasty.

This mixture is then kneaded with as large a quantity of the prepared blood as
it will take up that is about 100 to 150 parts by weight of the blood. The pieces
of dough are then baked in an oven the heat of which must be but slightly above
boiling point 212° F, because the albuminous parts lose their nutrimental value by
higher temperatures. The oven may suitably be an iron vessel with double walls
containing steam. When the pieces of dough are put in, the latter should be of
about 212° to 215° F, and when they have become well heated the oven should
still have a temperature of about 203° to 210° F. The oven may be provided
with means for regulating the pressure or temperature of the steam in the jacket.

PETER JENSEN of 33 Chancery Lane in the County of Middlesex "IMPROVE-

A principal object of this invention is to utilize the blood from slaughterhouses
for the production of food for animals; heretofore such blood has either been
allowed to run to waste or has at most been utilized for manure.
Food prepared according to this invention is exceedingly nutritious and whole-
some and is eaten with avidity by all sorts of animals and even by cows and
horses which otherwise have a strong dislike to the smell of blood. The food is
made into a kind of bread.
For the purpose of this invention the blood is first deprived of its fibrine, for
which purpose it immediately on issuing from the slaughtered animal is exposed
to agitation and cooling; for this purpose it may advantageously be treated in an
apparatus like a churn and having a cooling appliance at the bottom. To each
100 pounds of blood so treated are then added the albumen from about 25 pounds
of blood; this albumen is or may be produced by thinning the blood with water,
boiling, addition of acetic acid, and filtration, the albumen being deposited on the
filter.
The blood compound is then mixed with meal of any kind of grain, and with
straw or hay, crushed flax seed, the finest quality of bone meal, and salt. The
straw or hay serves partly to make up bulk, partly because it is of great
nutrimental value to animals and partly to give the bread the required lightness
and porosity, as no fermenting material is used lest the bread should not keep so

I claim as the invention communicated to me The manufacture and use for food
for cattle and other animals of bread composed of meal, straw bone meal, crushed

page_text: flax seed, salt and blood deprived of fibrine and albumen obtained from blood, the
said bread being baked at a temperature as little above the boiling point as possible,
all substantially as set forth.
In witness whereof I the said Peter Jensen have hereunto set my hand and
seal this third day of October in the year of our Lord one thousand eight hundred t
and eighty three.
