Description

IMPERIAL

PATENT OFFICE.

In many groves, not inconsiderable amounts of brushwood accumulate, for which a worthwhile utilization has not been available until now.

In-depth analytical-chemical investigations have shown that this is roughly the case in weak brushwood the same value of nutrient substance is contained as in a lesser amount of hay medium quality. In these investigations, the sticks showed a crude protein content of 5.25 pCt, 5.82 pCt, 7.5 pCt. and a digestible protein content of about. 2.9 pct. until 5 pct. Furthermore, a starch content of 5.2 to 10 pCt. found. The protein content, especially in digestible protein, is thus considerably higher than in straw, and this there is also the high starch content, which is also determined by the microscope Cells completely filled with amylum bodies were shown. These investigations now led to the idea that the sticks could perhaps be used in the manufacture of fodder.

Attempts have now been made to treat wood in such a way that the same can be obtained from taken from cattle. Thus, in patent specifications no. 32329 and 39428 are suggested been to scald wood flour with vinasse, to which hydrochloric acid is added, and to mix it into a thin paste, which after Can be fed for 2 hours or dried and, shaped into pieces, baked; or hydrochloric acid was allowed to act on wood flour for about 6 hours and after neutralization the acid with soda and with the addition of chlorinated lime the mass for a further 6 hours lie; this mass can also be baked. In addition, this feed meal can be made more palatable to the cattle by adding potato mash.

By such a manner of treatment, as by the inventor's research and by J. König, Landw. Zeitung for Westphalia and Lippe, 43rd year, 1886, no. 40, P. 345, is confirmed by that contained in the waste wood, 'only in small quantities Crude protein brought nothing or only an extremely small fraction into a digestible state, since 1.37 pCt. Raw protein only 0.06 pct. (equal to 0.01 pCt. nitrogen) can be shown to be digestible protein. There too the difference of 0.01 pCt found in two nitrogen determinations. Nitrogen inside If the analytical error limits lie, it is even doubtful whether digestible protein is present at all.

The other substances are also (in accordance with the information provided by J. König) not noticeably changed by the procedures mentioned. In addition there is the fact that because of the fineness of the wood flour, digestive disorders can easily be caused, for example by being too fine cut chaff.

Since hereafter the patent specifications no. 32329 and 39428 described procedures are to be described as unsuccessful and also the product created with it during its use can lead to intolerance (digestive disorders); there is also the sticks, which consists predominantly of bark and to a lesser extent of wood, of texture different from pure wood (old

wood), a procedure had to be found that would identify the errors and Avoids disadvantages of the known methods and then also of the peculiar ones mentioned Condition resp. Composition of brushwood takes into account and through production a digestible feed is a beneficial utilization of the almost in many forest areas worthless sticks made possible.

According to the observations and considerations mentioned above, this becomes the subject Methods forming the present invention are carried out as follows:

The brushwood, which can still be afflicted with leaf organs, becomes the context loosening of the cells without being too fineness of the individual particles To give rise to indigestion, squeezed (not pulverized) by doing the same expediently crushed by means of rotating rollers.

After the connection between the cells in the sticks has been loosened considerably, the same rbit ι is added to 2 pCt. Saline or livestock salt und _^2/2 to 1 cent. crushed malt. The mixture is moistened with water and put on heaps, so that self-heating and thus at the same time an implementation respectively. To a certain extent, a breakdown of the mass can occur. The malt makes the starch contained in the sticks soluble and the crude fiber is converted into a more digestible state under the further influence of moisture and self-heating, as is the crude protein. Such a heap (brewing heap) heats up to 60 to 80 ° C within one night, which suggests such a beneficial effect in the presence of the malt.

The water to be used for moistening can also be mixed with other aqueous liquids, as found in the agricultural enterprise, wholly or partially replaced be e.g. B. by stillage; you can also add other feed materials to the brushwood.

After the self-heating has taken place, the whole thing becomes a digestible one, the diet of the cattle has been converted into fodder, which is very beneficial to the animals, and which in large quantities is unobjectionable is assumed, which is not the case with merely squashed sticks.

The nutritional power of a feed obtained in this way is of the most favorable due to several months of use Successful guided feeding experiments have been ascertained.

With the help of this process, all kinds of sticks can be converted into animal feed. ,

Such sticks, which contain large amounts of tannin, such as spruce sticks, are made expediently in the squeezed state by leaching the tannin with cold water freed, whereby the loss of protein is extremely small.

The tanning liquor obtained can be used in the evaporated state for tanning purposes Find.

Claims (2)

Patent Claims: 1. A process for the manufacture of a fodder from brushwood, consisting in that the sticks are crushed and in a moist state, mixed with malt and piled up in heaps, the self-heating suspends. 2. For the method characterized in claim 1. the cold leaching of the squeezed Brushwood, before further processing into animal feed, with water, for the purpose of tannin-containing sticks the tannin without significant protein losses to withdraw, whereby the liquor obtained can be used for tanning purposes.
