Definitions

  • the present invention relates to a feed for improving feed efficiency of livestock.
  • nucleic acid synthesis using ife iJOTO as a substrate is immature, and it can be inferred that the effectiveness of nucleic acid administration will be further enhanced in animals at such a time. In animals, no reports have shown similar effects in livestock, and no reports have previously shown that promoting villus recovery can improve feed efficiency. Disclosure of the invention
  • the present inventors have found that administration of nucleic acid to livestock improves feed efficiency and promotes growth of livestock, and has completed the present invention. That is, the present invention relates to a method for improving feed efficiency of livestock by administering the nucleic acid to the livestock.
  • the timing of administration is preferably the weaning period.
  • a method of administering the nucleic acid a method of adding the nucleic acid to livestock feed and administering it is preferable.
  • animal feed milk substitute, prestar feed or starter feed is preferred.
  • Livestock refers to industrial animals for dairy, meat, or leather, such as cows, pigs, chickens, turkeys, sheep, and goats.
  • the nucleic acid used in the present invention corresponds to a nucleic acid that exists as a simple substance, or a bacterial cell such as a yeast or a cell that highly contains the nucleic acid. Further, as this nucleic acid, any of deoxyribonucleic acid and liponucleic acid can be used, and not only as a so-called high-molecular-weight nucleic acid, but also as a result of dephosphorylation of its constituent units, nucleotides and nucleotides.
  • nucleosides or any of the minimum units of purine or pyrimidine base.
  • nucleotides are adenosine monophosphate, guanosine monophosphate, cytidine monophosphate, peridine monophosphate, thymidine monophosphate, inosine monophosphate, and as nucleosides, these nucleotides are dephosphorylated.
  • Purine bases include adenine and guanine
  • pyrimidine bases include cytosine, peracyl, and thymine.
  • nucleic acids There are two ways to administer nucleic acids: adding them to livestock feed, or dissolving them in water and ingesting them when drinking water.
  • the nucleic acid can be given separately from the diet alone or as a mixture with sugar or the like which livestock prefers to take. It can also be tableted and administered forcibly. Of these administration methods, the method of adding to animal feed is most preferred.
  • the dose of the nucleic acid is preferably 0.05 to 5.0 g / day, more preferably 0.1 to 2.0 g day, per kg of livestock body weight.
  • the feed efficiency can be significantly improved even after the feeding of the nucleic acid-containing feed is stopped, so that the effect is further improved. It is a target.
  • Livestock feed to which nucleic acid is added is usually corn, barley, wheat, rye, sorghum, cereals such as soybean, yellow powder, soybean oil cake, soybean protein, oil and fat, skim milk, fish meal, meat-and-bone meal, blood meal, plasma Protein, whey, rice bran, bran, sugar, glucose, minerals, vitamins, salt and the like may be used alone or in combination.
  • cereals such as soybean, yellow powder, soybean oil cake, soybean protein, oil and fat, skim milk, fish meal, meat-and-bone meal, blood meal, plasma Protein, whey, rice bran, bran, sugar, glucose, minerals, vitamins, salt and the like may be used alone or in combination.
  • ruminants such as cattle, sheep, and goats, various pastures are fed as roughage in addition to the above feed.
  • the amount of the nucleic acid to be added to the feed is preferably 0.01 to 5.0%, more preferably 0.5 to 2.0%, based on the amount of a commonly used feed.
  • Nucleic acids can be added to feed and mixed to feed livestock. For example, when raising pigs, only breast milk is fed immediately after birth, but from one to two weeks later, an initial feed (prestarter feed) is fed in addition to breast milk. At weaning, the feed is switched to the initial feed (starter feed), and then it is fattened using fattening feed. In ruminants such as cattle, sheep, and goats, breast milk or milk replacer and solid feed are fed in parallel until rumen (ruminal) is formed. Switch. Addition and administration of nucleic acid to any of these feeds can improve feed efficiency.
  • the method for improving feed efficiency using the nucleic acid of the present invention is useful for application to livestock from the time immediately after birth to immediately after the feed is switched to the fattening period after weaning, and particularly to pigs.
  • 30 weaned male piglets and 30 weaned female piglets were used and divided into two groups: 30 control groups and 30 nucleic acid-administered groups.
  • Piglets were weaned at the age of 14 days, and for 14 days after weaning, the control group was treated with a commercial starter feed having the composition shown in Table 11, and the nucleic acid-administered group was treated with the commercial starter feed shown in Table 11 Test house with 0.8% ribonucleic acid extracted from brewer's yeast Was paid. After 14 days from weaning, the same nucleic acid-free feed (late-stage commercial feed) was supplied to both plots.

Abstract

L'invention concerne un procédé visant à améliorer l'efficacité de l'alimentation des animaux d'élevage, lequel procédé consiste à administrer des acides nucléiques aux animaux d'élevage. Il est d'ailleurs préférable, dans le cadre de ce procédé d'administration, d'ajouter les acides nucléiques aux produits alimentaires des animaux d'élevage. Lorsque l'animal d'élevage se nourrit, il est préférable d'ajouter des succédanés de lait, ainsi que des aliments de pré-début et des aliments de début.
