ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a process for the production of a feed based on green fodder, which has undergone a silaging process, as well as to a corresponding feed.
FIELD OF THE INVENTION
The energy density of feeds can be significantly increased by the use of fats. Hitherto use has been made thereof in the form of so-called fatting of concentrated feed mixtures. Such concentrated feed mixtures are often fed as a supplement to the standard silage. Silage, which constitutes the basic feed for animals, is nowadays usually produced in the following manner: Green fodder, e.g. cut grass, optionally following a predrying phase of 1 to 2 days, is pressed by means of a corresponding press into round bales and is then packed in airtight manner in film. Under the thus produced anaerobic conditions, enzymatic processes take place yielding and a controlled fermentation, which gives a corresponding silage product after about 2 months.
SUMMARY OF THE INVENTION
As a result of the at present, separate feeding of silage and feed supplements and the resulting increased storage requirements, the cost and time expenditure is raised.
The problem of the invention is consequently to make available a complete silage, i.e. requiring no supplements.
According to the invention this problem is solved in that at least one oil-containing and/or fat-containing substance is added to the green fodder prior to the silaging process.
Preferably, predried grass is used as the starting material for the silaging process.
The preferred oil-containing or fat-containing substances, which can be used in the process according to the invention, are soy oil, rape oil, coconut oil, palm oil or mixtures thereof or corresponding oil and fat-containing press cakes or pellets.
In another preferred embodiment of the process according to the invention, prior to the silaging process, it is also possible to add a mixture to the green fodder containing mineral substances, trace elements and/or vitamins.
Preferably use is made of an aqueous solution of the mineral substances, trace elements and/or vitamins.
The invention also relates to a feed, which is characterized by a content of at least one oil-containing or fat-containing substance, preferably in the form of soy oil, rape oil, coconut oil, palm oil or a mixture thereof or corresponding oil or fat-containing press cakes or pellets.
According to a preferred embodiment of the feed according to the invention, it is characterized by an additional content of mineral substances, trace elements and/or vitamins.
Preferably the feed according to the invention can be produced with the process according to the invention.
The hitherto performed tests have surprisingly revealed that oils or fat-containing additives, added to the green fodder, such as e.g. grass prior to the silaging process, can be uniformly mixed with the substrate. The originally feared demixing was not observed.
It is particularly noteworthy that the addition of oils and fat-containing additives does not significantly influence the fermentation of the silage. In fact, all the silage operations were successful.
The tests carried out up to now consequently allow the conclusion to be drawn that surprisingly, when silaging green fodder it is possible to add oil-containing and/or fat-containing substances without impairing successful conservation or preservation. In fact, a fatted basic feed is obtained, which constitutes a complete feed for animals, so that it is no longer necessary to add concentrated feed mixtures.
The fatted, novel feed is readily accepted by animals, i.e. no acceptance problems were observed. The novel feed can be used for different animal types. Although initially intended mainly for horses or cattle, a further use for other animals essentially fed on the basis of silaged green fodder is conceivable and possible.
