Benefits of technology

[0024]The problem proposed by the present invention is to design a technique for preparing food additives or feed rations for animals which makes it possible to substantially increase the concentration of capsaicinoids in the food additive and / or the feed ration, while at the same time limiting the irritant effect of the active molecule.

Problems solved by technology

At the current time, in intensive farming, it is difficult to maintain conditions suitable for optimal growth.
Many parameters interact between the animal and its environment, causing, in certain cases, problems which result in a decrease in the expected performance levels in the livestock, and retarded growth.
However, the repercussions of this practice on consumer health are currently being debated.
In these countries, the climatic conditions are not always favorable for many livestock farms.
Capsaicin cannot be used directly by animal feed manufacturers.
It is a highly toxic product which requires extremely strict handling conditions, and which must therefore be isolated.
The capsicum oleoresin is easier to use, although it is still a highly irritant product, which limits its direct use as an additive for animal feed.
Since it is liquid, the oleoresin is difficult to disperse homogeneously in a feed at the concentrations conventionally used for additives (from a few ppm to a few hundred ppm).
However, the economic and legislative constraints imposed on the animal feed industry greatly limit the techniques and the excipients that can be used for such a development.
Hot atomization, which is the technique most commonly used for microencapsulating plant extracts, cannot be used to meet the various objectives set.
This is because the microspheres produced are generally too pulverizing and therefore harmful, which means that the concentrations of capsicum oleoresin that can be microencapsulated must be greatly limited.
Furthermore, it is very difficult to obtain a formulation that can have a delayed effect by using this hot atomization technique.
In addition to the presence of organic solvent, which is not desirable, this method is not suitable in the case of high concentrations of irritant capsaicinoids, in particular in the case of a capsicum oleoresin, the irritant nature of which can be accentuated in the presence of water.

Embodiment Construction

[0057]The technology of cold-state atomizing in a gaseous atmosphere, illustrated by the atomizing device of FIG. 4, is first of all considered.

[0058]The cold-state atomizing device comprises an atomizing tower 4 of cylindroconical shape, a spraying means 3, such as a spray nozzle or a turbine, in the upper part of the atomizing tower 4, an air / powder separating system in the lower part of the atomizing tower 4, and a collector 6 for recovering the powder. The air / powder separation can be carried out by means of a cyclone system, in which the powder drops into a collector located at the base of the cyclone, whereas the air is expelled via the top by means of a fan. A container 1 comprises heating means 13 such as electrical resistance elements controlled by a sensor 14, so as to make liquid a mixture 2 introduced into the container 1. A pipe 17, with fluid-controlling means such as a valve 17a and a pump 17b, forces the liquid 2 towards the spraying means 3. A ventilation system 8, ...

Abstract

A food additive or feed ration for an animal contains an active agent including at least one capsaicinoid. The additive or ration is prepared by a method which includes the step of cold-state atomizing of granulating a liquid mixture containing an encapsulation fat, the active agent including at least one capsaicinoid. Solid particles of the mixture are thus produced. The cold-state atomization or the granulation act on the nature of the encapsulating fat, on the particle size, and on the temperature of the atomization step in order to control the capsaicinoid release kinetics in the digestive tract of animals.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates, in general, to compositions for animal feed, food additives for animals, and methods for increasing the zootechnic performance levels of animals.[0002]In livestock farming, the performance levels of the animal feed are generally characterized by the Average Daily Gain (ADG) and / or the food conversion ratio (FCR). The reproductive efficiency of the animals can also be considered.[0003]At the current time, in intensive farming, it is difficult to maintain conditions suitable for optimal growth. Many parameters interact between the animal and its environment, causing, in certain cases, problems which result in a decrease in the expected performance levels in the livestock, and retarded growth.[0004]Digestive disturbances constitute one of the principal causes of animal growth dysfunction.[0005]Antibiotics are commonly used in animal feed, by way of prevention, against such disturbances. This use consequently defines t...
