Description

Method for producing pelletized mineral feed

The present invention relates to a method for preparing an inorganic feed which can be molded into pellets without the need for a drying process and which is resistant to bacteria and is also easy to digest.

In order to increase the nutritional value of livestock feed, mineral feed consisting of powders of calcium and magnesium is used. However, these mineral feeds alone do not taste like livestock, and in the form of powder, the powder is attached around the mouth, so it is difficult to eat, so it is not necessarily good. For this reason, pelletizing said mineral feed is performed in order to make it easy to eat. Conventionally, in order to pelletize inorganic powders, an adhesive is added to the powders and molded using an extrusion press granulator such as a circular molding machine and a desk molding machine. However, in such a case, if the moisture content is small, there is a problem such as clogging the hole of the molding machine stand. Therefore, wet molding with a high water content (20 to 40% by weight) has been performed. By the way, in the case of wet molding, there is a problem that a drying step after molding is required, and the manufacturing process is complicated and the cost of the product is increased. In order to solve such a problem, the molding method which does not need the drying process which mixes plant leaf powder with mineral feed and reduces moisture content is also implemented. However, even in such a method, a new problem arises that mold generation cannot be avoided under a high temperature and high humidity environment. It is known to add a drug such as propionic acid in order to prevent the occurrence of mold, but such a drug is limited in the amount of addition, and may also be insufficient in the antibacterial effect.

The present invention provides a method for producing an inorganic feed which can be molded into pellets without the need for a drying step after molding, and which is antibacterial and easy to digest. A mixture of 60 parts by weight and 10 to 40 parts by weight of foliage or leaves is added to a mixture of 2 to 5% by weight of moisture and NaHCO ₃ 2 to 5% by weight to form a pellet.

As said minerals, calcium phosphate and calcium carbonate are main components, and magnesium carbonate, zinc carbonate, cobalt sulfate, copper sulfate, iodine calcium, etc. are used. Moreover, you may mix iron powders, such as iron sulfate and iron citrate, seaweed, etc. as needed. The type and compounding ratio of the minerals to be blended can be appropriately changed depending on the type of livestock, growth stage, growth environment, and the like.

Subsequently, as the foliage, legumes such as Alfalfa and Tymothy are used. As the leaves, legumes and deciduous trees, such as horse acacia and Ipilpil, are used. Since the foliage or the leaves contain fibers and fats and oils, when the pellets are formed, they act as a lubricant to prevent the powder from being firmly bound and to improve slipping. It is also a plant ingredient, which adds the animal's favorite taste to the feed.

The mixing ratio of the minerals is preferably 90 to 60 parts by weight, and the mixing ratio of the foliage or the leaves is 10 to 40 parts by weight. Mixing at least 40 parts by weight of the foliage or the foliage results in less inorganic content, and the price of the product is also higher, which is not preferable. On the other hand, when the mixed amount of the foliage or the leaves is 10 parts by weight or less, the function as a lubricant at the time of molding becomes insufficient.

In addition, the mixing amount of water with respect to the mixture of the above-mentioned inorganic substances and leaves or leaves is preferably 2 to 10% by weight. When it becomes 10 weight% or more, a drying process is needed after shaping | molding. At 2 weight% or less, the lubrication state at the time of shaping | molding worsens.

In the present invention, NaHCO ₃ (sodium bicarbonate) is mixed with 2 to 5% by weight based on the mixture. When NaHCO ₃ is mixed in a predetermined amount, mold development is prevented by its sterilization action, and digestion of feed is promoted by an antacid and digestive action, thereby promoting growth. If the mixed amount of NaHCO ₃ is 5% by weight or more, the effect of preventing mold development will not be improved accordingly, and the amount of minerals to be contained will be small. In addition, when NaHCO ₃ is 2% by weight or less, the effect of preventing sterilization and mold development is reduced, and the action as an antacid and a digestion accelerator is also reduced.

NaHCO ₃ may be used together with saline or ammonium chloride (NH ₄ Cl). When salt is added to the feed, the animal's favorite taste can be improved, thus improving the palatability of the mineral feed. On the other hand, NH ₄ Cl not only increases the nutritional value, but also has a preventive effect against urolithiasis in livestock, and when combined with NaHCO ₃ can exert their effects. The addition amount of the salt and NH ₄ Cl is preferably 1 to 5% by weight. If it is 1 weight% or less, there is no addition effect, and even if it adds 5 weight% or more, an effect will not improve and the amount of other mixed components will become small.

Moreover, you may add an adhesive to the mineral feed of this invention mentioned above. Molasses, methyl cellulose, starch and the like can be used as the pressure-sensitive adhesive. As for the addition amount of an adhesive, 1-10 weight% is preferable. When added at 10% by weight or more, the content of minerals, leaves and leaves is reduced, and when it is 1% by weight or less, the effect of addition is insufficient. By adding the pressure-sensitive adhesive, the strength of the pellets can be improved and the shape can be prevented from being collapsed during molding.

In the present invention, the relationship between the amount of NaHCO ₃ added and the antifungal effect is shown in the following table.

In the above table, − indicates no mold occurrence, + indicates mold occurrence, and ++ indicates significant mold occurrence. As apparent from the above table, the mixing of NaHCO ₃ 2 to 5% by weight does not confirm the occurrence of mold at any of 20 ° C., 80% rh, and 30 ° C., 80% rh. Suitability is proved.

According to the production method of the present invention described above, feed for dispensing minerals important as nutrients for livestock can be easily pelletized without the need for a drying step, and the obtained feed prevents the occurrence of mold. It is antibacterial and easy to digest.

As a result of leaving the mineral feed at a constant temperature of 30 ° C. and a relative humidity of 80%, no mold was observed even after 21 days.

Example 2

After mixing the raw materials shown in the following table, by using an extrusion molding machine to produce a pellet-type feed having a diameter of 3 × 5 to 8 mm. The pelletization rate is 98%, and the strength after pellet molding is 1.8 kg / cm 2.

As a result of leaving the inorganic feed at a temperature of 30 ° C. and a relative humidity of 80%, mold development was not confirmed even after 21 days.
