Process for the use of fast autolysed brewer's yeast as fodder

The present patent application relates to the basic uses of brewer's rice residues as cattle feed, which contain yeast in suspension and have been made suitable for digestion by means of an autolysis process, this process being based on a slight increase in temperature and by adding table salt or sodium chloride in the appropriate amount can be initiated. ¹ ^

In beer production one receives as a sub-product or by-product a broth containing variable amounts of between 12 and 15% yeast in the suspension.

As is known, the yeast consists of several strains of Saccha-

romyces Cerevisiae and is by its nature not . en

suitable for direct consumption or consumption due to the Fact * that they, albeit nitrogen in greater Containing amount, leads to harmful changes in the digestive system.

The mean analysis of these yeasts, based on the dry state, is as follows ι

It is therefore a product with a very strong. ken content a, n vitamin B and proteins and that is undisputed is important for the feeding of cattle as soon as the end products, which have a negative effect on the decomposition or digestive process, are destroyed are.

The investigations into the use of brewer's yeast as fodder were aimed at getting in the way an accelerated autolysis and a low one or reduced temperature an inert broth with a protein content that is important for cell destruction, which also the preservation of vitamins without destruction dough serves to preserve.

Given the ersielten under those tests results it was thought now because the autolysis eut shortening the treatment could be accelerated to the liauer one day at 40 ⁰ C ι it so the tests were the addition of 5? ° saline and potassium chloride for Yeast suspension repeated.

The above figures show that the process could already be accelerated, so that only the optimum point with regard to temperature and salt concentration had to be determined. liach a series of experiments using different Autolysenbesehleuniger carried out or were repeated and the expired at various temperatures, the optimum concentration of sodium chloride than an operating temperature of 32-36 ° in the range between 5 x 5 and 4.0 i 'lying was determined .

From the results obtained in this way, the following was derived:

1. that by heating the broth, which contains the yeast in its state corresponding to the end of the manufacturing process, even without adding salt at a. Temperature of 4O ⁰ C a rapid decomposition and thus a complete destruction of the living cells is achieved;

2. that the final pH value of the liquid varies between 5.00 and 5.5-5.8?

3. that the free nitrogen content after Centrifugal separation of solids from 60/70 mg per 100 ml to 640-690 SDig moved; /

4. That the killing effect of sodium chloride is already evident after a short time shows when the amount is 5 # and the temperature eats low. From the age of 25 this destructive effect increases rapidly and after the end of 5 Can be regarded as complete after addition. .

In addition to the already indicated laboratory tests Certain problems remained to be resolved, for example with regard to the potential tendency towards contamination of the new preparation, the extent to which one such refusal to leave is still acceptable for cattle

The trials were carried out both in the industrial sector and in the nofmalen Framing by pitting pregnant and in the Rearing cattle as well as fattening pigs and -cattle carried out · The following have been carried out Results achieved!

1. Several cows of the Andalusian breed Retinta were born in the stable -hired, only with one off

The results were extremely satisfactory because * both pregnancy and litter normal .. were and there for the rearing of the calves for several months Breast milk was used exclusively, with the calves maintaining their normal weight and their good weight Maintained appearance.

2. the beef cattle were fed as follows »

b) Calves weighing 10 to 15 kg with spent grains plus 25 # autolyzed yeast *

the weight gain of the former was 480 grams and the latter 780 grams per tsg at the beginning and 960 grams during the second phase * In both cases there was no There is a lack of vitamins.

After the above-mentioned verifications, which lasted longer than a year, the period of time that was considered necessary to determine the extent to which the use of autolyzed yeast for feeding whatever livestock was considered to be concluded, since at the same time, i.e. after these experiences were made _f had also chickens and horses were fed with the same mixture as the beef cattle.

INDUSTRIAL PROCESS

The starting material used is a bouillon which is contained in

of beer production, which can be easily achieved by pumping

can be withdrawn from the fermentation or reserve cellar and contains 12 to 15 fi yeast in suspension «

This liquid is placed in the container of a special -Cistern wagon, which is used with an agitator Drive is provided by an engine PTO.

This vehicle has a small compartment in its Zöna behind the cabin for storing plastic bags _? which are filled with table salt (sodium chloride), which is added to the flefesuspenaion while dissolving in and mixing with it during transport by the action of a centrifugal pump, which has an extremely strong stirring effect.

Due to the fact that the temperature corresponds to the ambient temperature is. depending on the season changeable and therefore from the main phase of the autolysis treatment independently, which later than in the actual agricultural operation, where one daa feed for the Produces cattle, takes place.

After reaching its destination, the cistern wagon is equipped with the emptying pump belonging to its equipment with a force of 16 JS emptied and the bouillon quickly, i.e. in less than 5 minutes, in reserve memory or "filled into the Autolyaekaminer" if necessary The car can then be filled with a new yeast filling pick up

The time and temperature of the treatment are appropriate the; each'desired properties controlled; once this treatment is established, it is held
