Description

The present invention relates to an additive for ruminant feed in the period of feeding green fodder or grazing, which contains acetic, propionic and lactic acid salts.

Until now, acetic, propionic and lactic acid salts have not been used as additives in conventional feed practice. However, research and feeding experiments have found a positive effect of these substances on milk yield and fat content. A drawback of the experiments carried out so far, some of which have been carried out on an industrial scale, was that the authors considered acetic acid salts only as an energetic, rapidly absorbable source or as a precursor of lactic fat fatty acids. Therefore, they used relatively high daily doses of salts, which for example for dairy cows amounted to 250 to 1000 grams per head per day. The costs of the relatively, expensive and at such doses used preparations were not fully compensated by the increased performance of the animals and therefore, in practice, the feeding of the salts of said acids was not widespread due to inefficiency.

These drawbacks eliminate the green feed additives according to the invention, the use of which results in a rumen fermentation stimulating effect.

As has been found, when stimulating slurry fermentation with the ingredients of the present invention, a significantly higher amount of volatile fatty acids is produced from the same feed ration than from the dose that has been stimulated. Since the volatile fatty acids produced in the rumen by fermentation of the ration are the main energy source in ruminant metabolism, stimulation results in a better utilization of energy and nutrients from the ration that would otherwise pass through the digestive tract.

Importantly, it has also been found that stimulation can be induced in an economical manner. When using pure individual salts of acetic acid or propionic acid, a dose of 50 grams is sufficient for a dairy cow. For smaller ruminants the dose is even lower. In addition, the economy of use of the ingredients of the present invention is that stimulation can be induced by ingredients that are essentially conventional fermented feeds containing acetic, propionic, lactic and others.

However, these additives must be neutralized prior to feeding. Various types of silage, or possibly silage or other bulky or other feeds where fermentation and formation of the required amount of acids are best suited for this purpose.

The neutralization of the acids in the feed can be done preferably by spraying the feed with a solution of an alkaline composition, or by sprinkling a solid composition, optionally by mixing in an alkaline-acting feed, such as leached straw. Regarding the use of the individual synthetically prepared salts of acetic acid or propionic acid, solid or solution application is possible.

The use of more additives according to the invention than is strictly necessary to induce stimulation is by no means a defect, but somewhat reduces the economy when using relatively expensive synthetic pure acid salts. In the case of the use of fermented fodder, the acid content and the composition of the total ration from the feed point of view are limiting. Using conventional si195587 bales, stimulation in dairy cows can usually be triggered by adding several kilograms to one feeding.

Stimulated rumen fermentation using the ingredients of the invention results in increased energy production from a given ration, resulting in a significant increase in animal performance. E.g. in dairy cows, milk yields can be increased from a few tenths up to one liter or more compared to the same ration which was fed without stimulation. The chemical composition of the rations also plays a role.

Thus, while preserving the original performance of the animals, the feed of the invention can be achieved by reducing the cost of feeding.

The use of the additives according to the invention poses no health risk to the animals, since the stimulant substances used are used

Claims (4)

they are identical to the normal rumen fermentation products, and their levels are many times lower than the normal total rumen volatile fatty acid production of 3,000 to 5,000 grams per day for dairy cows. On the other hand, it has been found that the use of the ingredients according to the invention has resulted in an improvement in the health status of the dairy cows, which has been manifested, for example, by improved mating. This finding is quite understandable, since in the case of green feeding, the rations usually do not have enough energy and contain excessive amounts of nitrogen, which cannot normally be metabolized without the necessary amount of energy. As found, milk from dairy cows fed with the ingredients of the invention did not significantly affect the composition of the milk or its technological properties.
