CS253331B1 - Whey-based feed compound - Google Patents

Abstract

By mixing and homogenizing liquid whey, which on its own does not have the prerequisites for penetrating into feed rations, with liquid, pressed or dried yeast, a liquid mixture is obtained that is capable of drying in conventional drum or belt dryers. This mixture can be applied to a natural carrier before drying and dried together.

Description

The present invention relates to a whey-yeast feed composition.

Whey in its original state does not have the prerequisites for independent use in feed rations especially for low dry matter content, high salt content, short shelf life in relation to the quantity produced and the possibility of direct consumption in animals.

For these reasons, in virtually all dairies, whey is disposed of. Yeasts (eg yeast, brewer's yeast waste), whose dry matter can be increased before dispatch (eg by thickening, pressing), especially in order to recover the filtrate and return it to production and further increase durability of concentrated yeast. However, even this shelf life is far from meeting the requirements for long-term storage and maintenance of feed rations evenly throughout the year.

The above-mentioned disadvantages are overcome by the production of a compound feed, the principle of which is to mix and homogenize the proportion of whey and the proportion of liquid or thickened, respectively. Drying yeast, their subsequent drying on a suitable type. Dryers with the possible use of spraying the liquid mixture on the natural material (carrier) with subsequent drying.

The advantages of the feed composition according to the invention are the evaluation of whey, the improvement of the ecology of waste water in dairies, the use of naturally difficult to feed natural carriers, the long-term shelf life of the composition, the ease of storage.

Examples of compound feed process

1. · Whey + pressed yeast

600 l of whey with a dry matter content of approx. 6% are homogenized with 400 kg of pressed yeast with a dry matter content of approx. 25%. The resulting mixture of approx. 1 t and dry matter of approx.

2. Whey and liquid yeast

500 l of whey with a dry matter content of about 6% are homogenized with 500 l of liquid yeast with a dry matter content of about 8%. The resulting mixture in an amount of about 1 tonne and about 7% dry matter is gradually dried in a suitable type of dryer.

3. Whey + liquid yeast + carrier

500 l of whey with a dry matter content of about 4% is homogenized with 500 l of liquid yeast with a dry matter content of about 6%. The resulting mixture is sprayed immediately before drying with a natural carrier (or mixed directly into a liquid mixture) in a liquid: carrier ratio of 1: 0.1 to 1: 5 by weight. This is followed by drying in a suitable type of dryer.

4. Whey + dry feed yeast + carrier

900 l of whey with a dry matter content of approx. 6% is homogenized with 100 kg of dried fodder yeast with a dry matter content of approx. 90%. The resulting mixture of about 1 tonne and about 15% dry matter is fed to the natural carrier (optionally mixed with it) in a liquid: carrier ratio of 1: 0.1 to 1: 5 by weight. This is followed by drying in a suitable type of dryer.

Claims (2)

SUBJECT OF THE INVENTION Whey-based feed composition characterized in that before drying it consists of 100 parts by weight of whey and 10-200 parts by weight of yeast, depending on the dry matter of the whey and the dry matter of the yeast, preferably brewer's or feed yeast. 2. A compound feed as claimed in claim 1, characterized in that it is applied to a carrier of natural material.
