Description

  The present invention relates to a herb-containing formula feed for young piglets that has the same growth performance as the added formula feed without adding an antibacterial feed additive.

In recent years, from the viewpoint of the emergence of drug-resistant bacteria in humans, regulations on the items of drugs and antibacterial agents used in livestock feed have been advanced. In Europe, the addition of antibacterial agents for the purpose of promoting the growth of livestock in January 2006 There is a background that has been banned more completely.
In Japan, safety of livestock products is maintained by confirming the amount of livestock products used without any residue and regulating the amount of addition in accordance with laws and regulations. There is also a consumption trend that demands livestock products that are produced without the use of any sex agents, and pork produced without the use of antibacterial feed additives is also distributed to the market in order to thoroughly manage the hygiene of the farm. Yes.
The antibacterial feed additive here refers to morantel citrate, destomycin A, zinc bacitracin, aviramycin, and the like.

However, in the case of pig farming, the biggest problem at the site where this antibacterial agent-free feed is used is the production site of young piglets immediately after weaning, and even in farms that maintain a high hygienic environment, There are many cases where it is not possible to avoid problems such as growth stagnation and the occurrence of diarrhea due to breeding without the addition of.
In the first place, infant piglets from just after birth to around 70 days of age are not as resistant to disease as other infant animals.
In addition, since the antibacterial feed additive also has an effect of promoting growth, when it is not added, there is a problem that the growth performance of the piglet particularly at this young age stage becomes lower than that of the normal additive feed.
Furthermore, when a synthetic antibacterial agent or antibiotic drug is used continuously, drug-resistant bacteria appear, and there is a problem that the infectious disease suppressing effect is remarkably reduced.

  As a means for solving these problems, a mixed feed for young livestock is required that has the same level of growth performance and does not contain an antibacterial feed additive and has a low incidence of diarrhea.

As a mixed feed for livestock that does not contain an antibacterial feed additive, a method (patent document 1) is proposed in which an extract component of Kumazasa, which is a natural component, is blended with a livestock feed instead of an antibacterial feed additive. .
This invention utilizes the effect of suppressing the growth of fungi and viruses of the extract of Kumazasa, and is characterized by adding 30% by weight or less of an additive containing Kumazasa to a feed for pets or livestock. It is.

However, Kumazasa has a unique flavor even though it is a natural product, and especially piglets are highly sensitive to palatability, so they do not eat well and do not increase their intake according to growth, etc. There is a problem.

  The object of the present invention is to provide a feed for young piglets that does not use any antibacterial substances added to the feed, and improves the growth performance of the piglets at the early childhood stage by blending the feed.

As a result of research on an antibacterial agent-free feed that substitutes for this antibacterial substance, the present inventors have found that the performance differs depending on the nutritional level.
As mentioned above, in the case of formula feeds for young piglets without the addition of antibacterial agents, the biggest problem is the occurrence of diarrhea, i.e. when the feed to be fed after weaning is free of the addition of antibacterial agents. There are often cases of stagnant growth with diarrhea. To solve this problem, a combination study of the lactose content and the crude protein content in the feed revealed that there was little occurrence of diarrhea and growth stagnation when fed a dietary feed with nutritional level and no antibacterial agent added. Although there are few, it has been found that the growth of the fed piglet is improved when a specific herb is added to such feed, and the remarkable growth improvement can be seen by adding the organic acid together with the herb, resulting in the present invention. Is.

In the present invention, by adjusting the contents of lactose and crude protein in the feed, and further adding a specific herb or the herb and an organic acid at the same time, the growth performance of the piglet at the early childhood stage is improved. Feed can be obtained.
That is, the present invention contains lactose in feed in an amount of 20% by weight or more, suppresses the content of crude protein to 20% by weight or less, further adds a specific herb or the herb and an organic acid at the same time, and The present invention relates to a formula feed for lactating piglets characterized by a nutritional design containing an amino acid in an amount necessary for pig growth, and includes the following aspects.
(1) For infant piglets containing at least 20% by weight of lactose, having a crude protein content of not more than 20% by weight, and further blending at least one of Maria Thistle, Anise, Garlic and Koroha Formula feed.
(2) The mixed feed for young piglets according to (1), further containing an organic acid.
(3) The mixed feed for young piglets according to (1) or (2), further comprising amino acids necessary for the growth of piglets.

  In order to contain 20% by weight or more of lactose in the feed, lactose may be added to the feed or the amount of feed raw material containing lactose may be increased. Examples of feed materials containing lactose include lactose, skim milk powder, whey powder, concentrated whey protein, and the like.

  On the other hand, in order to make the content of the crude protein in the feed 20% by weight or less, it is necessary to reduce the blending ratio of the feed raw material containing the crude protein such as soybean protein as much as possible. Examples of feed materials containing crude protein include fish meal, skim milk powder, and soy protein. When these ingredients are used in combination, the total amount of each crude protein is 20% by weight or less based on the total amount of feed. It is necessary to adjust the blending amount so that

As herbs to be blended in the feed, it has been found that Maria thistle, anise, garlic, and Koroha have an effect on improving the growth of piglets. Mixing any one or more of these improves the growth of the piglet, but it is more desirable to use a mixture of the four.
These herbs can use any of their leaves, stems, seeds, flowers, and roots, but it is convenient to use commercially available dry powder products.
The herb content is preferably about 0.001 to 1.000% by weight based on the total amount of feed in terms of air-dried matter.

  Examples of the organic acid blended with the herb in the feed include formic acid, citric acid, and lactic acid, and formic acid is particularly preferable. Moreover, the blending amount of the organic acid is desirably about 0.001 to 1.000% by weight with respect to the total amount of the feed.

  Furthermore, it is necessary to secure the amount of amino acids necessary for the growth of the young livestock in order not to reduce the growth performance of the livestock at the early childhood stage. Examples of amino acids blended in the feed include lysine, methionine, and threonine. The amino acid level is desirably 1.000 to 1.800% by weight as the content of lysine in the feed.

Demonstration example

Prepare 8 weaned piglets per ward, feed with antibacterial agent (control zone I), feed without antibacterial agent and 20% crude protein (test zone I), antibacterial No additives, 20% by weight of crude protein, feed containing 4 kinds of herbs (Test Zone II), no antibacterial agent added, 20% by weight of crude protein, no organic acids Prepare 5 types of feed, containing feed (Test Zone III), no antibacterial agent added, 20% by weight of crude protein, and feed containing 4 kinds of herbs and organic acids (Test Zone IV) I paid for two weeks.
Table 1 shows the ratio of each feed.

  Such a test was repeated 5 times to investigate changes in body weight before and after the test, incidence of diarrhea during the test, and the like. The results are shown in Table 2.

  As shown in Table 2, although the incidence of diarrhea and loose stool was slightly higher in the test group I piglets compared to the control group, the weight gain and feed demand rate were almost the same as in the control group by reducing the content of crude protein. It became equivalent. In Test Zone II, the addition of herbs was able to reduce the incidence of diarrhea and loose stool, increased body weight gain, and improved feed demand. In Test Zone III, by adding an organic acid instead of herbs, the incidence of diarrhea and loose stool could be further reduced, and the weight gain was further improved. In test group IV, when herbs and organic acids were added in combination, the incidence of diarrhea and loose stool was significantly reduced, and the amount of gain was increased by 10% or more compared to the control group.

  According to the mixed feed of the present invention, since synthetic antibacterial agents and antibiotics are not blended, it is possible to provide safe meat to consumers, and further, the incidence of piglet diarrhea can be suppressed, and the amount of feed intake Therefore, livestock can be raised efficiently.
