Description

[Detailed description of the invention]

a. Industrial Application Field The present invention relates to a pelleted mixed mineral feed for cattle. b. Prior Art Mineral-containing feed containing various ingredients is used for ruminant animals such as cows. The rumen of ruminants is an important organ responsible for energy production. In other words, the rumen can be simulated as a continuous fermentation tank in which the microorganisms living there ferment and decompose ingested nutrients to produce volatile fatty acids (VFA) as an energy source. The fermentation that takes place there is influenced by various factors, but the pH value in the rumen is an especially important factor. In other words, its PH value is
At around 6.5, the pH value of the ruminal fluid is most functional, and a decrease in the PH value of the ruminal juice changes the fermentation pattern in the rumen, which has been thought to be associated with various metabolic disorders. c Problems to be solved by the invention However, in recent years, especially regarding milking cows,
As milk production increases, there is a tendency to feed large amounts of concentrated feed with high energy value in order to supplement that energy. In other words, by feeding feed that is easily fermented and decomposed, the fermentation pattern is different from that of roughage-based feed, and the rumen juice is increased.
The PH value is the pH at which the rumen is said to function best.
It showed a lower value than the normal value, which in turn was linked to various disorders such as acidosis and ketosis. Therefore, in order to prevent this drop in PH value, sodium compounds such as sodium bicarbonate (NaHCO ₃ ), which have a buffering effect on the pH in the stomach, have been fed for a long time. However, sodium compounds such as sodium hydrogen carbonate have extremely poor palatability to livestock such as cattle, and problems remain in how to feed them. In addition, various attempts have been made to pelletize mixed feed for livestock for the purpose of improving palatability, and in all cases, molasses, starch, or carboxymethyl cellulose are used as binders. However, these methods have various drawbacks such as difficulty in adjusting the pellet shape and insufficient granulation yield. In particular, sodium compounds such as sodium bicarbonate are unstable to heat and water compared to calcium compounds, which are the main components of conventional pelleted mixed mineral feeds, and are easily worn out during the granulation process. has been considered extremely difficult. The present invention has been made in view of the above-mentioned circumstances, and in order to solve the above-mentioned problems, it is necessary to use an inexpensive food fermentation sub-acid which has not yet been used as a binder in the field of conventional feed manufacturing technology. The present invention aims to provide a pelleted mineral mixed feed that is highly palatable and has a good granulation yield. d Means for Solving the Problems In order to solve the above problems, the present invention aims to solve the above problems by
40-90% sodium compound to maintain the value, and 5-5% of Nara pickle lees, sake lees, or shochu lees as a binder.
Pellet mineral mixed feed for cattle with 15% additive. The present invention will be explained in detail below. First, in the pelletized mineral mixed feed according to the present invention, in order to pelletize the mineral mixed feed, after adjusting the moisture content of the mixed raw materials according to the present invention, which will be described later, and then kneading (kneading) the predetermined amount. The pellets may be granulated using an extrusion pressure granulator, such as a ring-type or disk-type pelletizer, and then dried to form a product. In the present invention, as the main component of the raw material in the pellet granulation, a sodium compound of 40 to
90%, and further 1 to 25% of specific food fermentation by-products depending on the content of the sodium compound,
Preferably 5-15% is added. The sodium compounds include sodium hydrogen carbonate, sodium hydrogen phosphate (Na ₂ HPO ₄ ),
Sodium dihydrogen phosphate (NaH ₂ PO ₄ ) or the like is used. If this sodium compound is below 40%, the PH
This is not preferable because the buffering effect that prevents the value from decreasing decreases.
Moreover, in cases of 90% or more, palatability cannot be improved. The food fermentation by-products are residues of pickles, pickled lees, etc., such as Narazuke (Moriguchi-zuke) lees, sake lees, and shochu lees. If this food fermentation by-product is less than 1%, its effects as a binder and for increasing palatability will be low, and the recovery rate of granulated pellets will be low. Furthermore, if the food fermentation by-product accounts for 25% or more, a binder will be added unnecessarily and the addition of other necessary ingredients will be restricted by that amount, which is not preferable. Food fermentation by-products range from 5 to 15.
The most favorable effect is reliably achieved within the range of %. Those with a content of 5 to 15% have a high strength pellet shape.
Moreover, a product with high palatability can be obtained. Therefore, by using this food fermentation by-product as a binder, it is possible to obtain a pelleted mineral mixed feed containing sodium compounds as a main component, which is highly palatable and has a good granulation yield. e Example (1) 650Kg of sodium hydrogen carbonate, 100Kg of sodium dihydrogen phosphate, 50Kg of magnesium carbonate, 50Kg of alpha-alphamil, and 120Kg of dry powder of Narazuke lees (moisture 15%) as a food fermentation by-product.
After blending 30 kg of water, mixing well and kneading, it was granulated using a disk-type extrusion molding pelleter and fluidized to dry, resulting in 958 kg of pellets with a strength of 5.8 kgw/cm ² , a diameter of 6 mm, and a length of 10 to 12 mm. . On the other hand, as a comparative example, 120 kg of cornstarch was used instead of 120 kg of food fermentation byproducts in the above formulation.
When pelletized in the same manner as ^the one containing
Obtained 782Kg. Next, after feeding these two types of pellets,
For each of the 15 milked cows that have been milked for 1 hour,
A portion of 100g was given to the animals, and the amount of food eaten and leftover food was examined. As a result, 12 out of 15 animals collected the pellet containing the food fermentation byproduct first. After one hour, the amount of leftover food is approximately
However, in the comparative example, 6 animals did not eat the pellets at all, and the amount of leftover food after 1 hour was about 1100 g in total. (2) Next, approximately 5 kg of each of the mixed feeds of Samples A, B, and C shown in Table 1 were pelletized using a disk-type extrusion-type pelletizer testing machine.

[Table] Table 2 shows the results of investigating the recovery rate, sodium bicarbonate content, and pellet strength after standing for 1 hour for each sample.

[Table] As is clear from Table 2, Sample A using food fermentation by-products is superior to Samples B and C using cornstarch and molasses in terms of recovery rate, sodium bicarbonate content, and pellet strength. It can be seen that (3) 650Kg of sodium hydrogen carbonate, 100Kg of sodium dihydrogen phosphate, 50Kg of magnesium carbonate, 130Kg of crushed sake lees, 50Kg of alpha alpha amil, water
After blending 20Kg, mixing well and kneading, it was granulated with a disc pellet mill, fluidized and cooled, resulting in a pellet strength of 5.7Kgw/cm ² , a diameter of 6mm,
945 kg of pellets with a length of 10-15 mm were obtained. Next, 100 g of each of these pellets was administered to 10 milking cows one hour after feeding, and as a result of checking whether the pellets were eaten or uneaten, 6 of the 10 cows ate the entire amount within 15 minutes after administration. 2 dogs after administration
I ate the whole thing in 30 minutes. The remaining two animals only partially ate the food, and the total amount of food left over from the two animals 1 hour after administration was 140 g. Therefore, it was confirmed that the taste was good. (4) 650Kg of sodium hydrogen carbonate, 100Kg of sodium dihydrogen phosphate, 50Kg of magnesium carbonate, 120Kg of crushed shochu lees, 50Kg of Alpha Alf Amil,
After blending 30 kg of water, mixing well and kneading, the pellets were granulated using a disc type pellet mill, fluidized and cooled, resulting in a pellet strength of 5.7 Kgw/cm ² and a diameter of 6 mm.
955 kg of pellets with a length of 10-15 mm were obtained. Next, feed these pellets in the same manner as feed 1.
When the drug was administered to 10 milking cows after an hour, 5 of the 10 ingested the entire amount within 15 minutes, and 2 ingested the entire amount within 30 minutes. Of the remaining three animals, one did not eat at all, and two only partially ate, leaving 3 ounces of food left over one hour after administration.
The total weight of the head was 260g. Therefore, it was confirmed that the taste was good. (5) As shown in Table 3 below, each of the mixed feeds of Samples D and E using the sake lees and shochu lees were pelletized in the same manner to about 5 kg each.

[Table] Table 4 shows the results of investigating the recovery rate, sodium bicarbonate content, and pellet strength after 1 hour of granulation for each sample.

[Table] Samples D and E have almost the same data as Sample A shown in Table 2 in terms of recovery rate, sodium bicarbonate content, and pellet strength, and have been conventionally used as binders for pellets. It was confirmed that this method was superior to those using molasses or cornstarch. f. Effect of the invention As described above, the pelleted mineral mixed feed according to the present invention has a lower preference for feeds containing sodium compounds such as sodium bicarbonate that buffer the intragastric PH used as mixed feeds for cattle. It is possible to improve the properties of the pellets, the strength of the pellets, and the granulation yield.
