Abstract

At preservation of glycidic fodder by means of anaerobic fermentation by epitiphal microflora and eventually also by probiotics the homogenization of the fodder with 0.01 to 1 percent by weight of ionophore reduces the contents of acetic acid in the fodder. The example of natural ionophores is represented by antibiotic "menenzin".

Description

(57) In the conservation of carbohydrate feeds by anaerobic fermentation with an epiphilic microflora and, where appropriate, probiotics, homogenisation of the feed with 0,01 to 1% by weight ionophore reduces the acetic acid content of the feed. An example of natural ionophores is the antibiotic menensin.

The invention relates to a method for the preservation of carbohydrate feeds by anaerobic fermentation with an epiphase microflora and optionally also with probiotics.

The preservation process for carbohydrate feeds is conditioned by an epiphyte microflora, or a multifunctional culture, which results from the introduction of a suitable microflora to the original microflora.

IN

In current feed preservation methods in silage troughs or large-capacity silos, fermentation of carbohydrate present in the feed is utilized in an anaerobic environment. In addition to carbon dioxide, methane and hydrogen, fermentation products include alcohols and volatile fatty acids. The composition of the mixture of volatile fatty acids and the amount of hydrogen formed affects the quality of the canned feed, its energy content and taste.

Therefore, probiotics, i.e. stabilized cultures of suitably selected symbiotic microorganisms with specific metabolic properties, which favorably influence the composition of metabolic products, are added to the conserved mass.

When the preservation process is disturbed, acetic acid is produced predominantly, which is disadvantageous from the point of view of dietary incorporation of such feed into the feed ration, since it does not taste to animals and the use of acetic acid is metabolically disadvantageous.

The above-mentioned disadvantages are eliminated by the method of preservation of carbohydrate feeds by anaerobic fermentation with an epiphase microflora and possibly also by probiotics, which is based on the fact that the carbohydrate feed is homogenised with 0.01 to 0.1% by weight. ionophore.

An advantage of the method according to the invention is that the composition of the resulting mixture of metabolites is influenced not by changes in the proportion of fermenting microorganisms, but by the change of their enzymatic activities through selected ionophores. These in microorganisms significantly reduce the activity of, for example, acetate kinases, so that the formation of the undetected undesired acetic acid in the preserved mass is limited.

Ionophores are both natural and artificial substances that selectively complex specific cations that are involved in the metabolism of living organisms and carry them through lipophilic membranes against a concentration gradient. Natural ionophores include, for example, the antibiotic monensin or cholanic acid. Artificial ionophores include multidentant ligands such as crowneters, cryptands, and their open-chain analogs.

and

The homogenization of the carbohydrate filler with ionophores can be carried out by all known methods used in the preservation of the carbohydrate fillers at any stage of their transport, treatment and storage. Thus, the ionophores can be added to the feed during cutting or crushing, or during transport of the feed to the silage chambers or during storage in the silage chambers. The choice of the optimum addition site will be influenced by the form in which the ionophores will be applied, whether in powder, solution or suspension form. It is advantageous to combine this operation with other feed modifications, for example with occlusion of probiotics or with the addition of inorganic salts, flavoring agents or with the mixing of several types of feed.

Ionophores are already effective at very low concentrations even below 0.1% by weight. This requires that the homogenization of the bladder is carried out very carefully. The advantage of preserving the feed according to the invention is to reduce the acetic acid content of the feed, which degrades the feed by its unpleasant taste, so that the silage feed is poorly absorbed by the animals. By reducing the acetic acid content, the quality of the silage is improved and improved.

The following examples illustrate the invention. Monensin was used in the form of an aqueous solution obtained from a solid preparation of monensin.

Example 1

The mechanically pretreated beet pulp mass was homogeneously melted with monensin at 0.05% by weight. On removal of the treated mixture, only 10% of the amount of acetic acid was found versus the amount of the same acid in the mass preserved in the absence of the ionophore.

Example 2

Mass of maize for silage with a dry matter content of 18% by weight was stored in the usual manner with the addition of monensin at a concentration of 0.4% by weight. The amount of acetic acid was 1/20 of the amount of this acid present in the mass preserved without ionophore.

Example3

Sieved sugar beet pulps silage with added 0,2% wt. ionophore contained 250 wt. more propionic acid than the same beet pulps preserved in the absence of ionophore.
