Description

  The present invention is for ruminant feeding that protects vitamin C, which can improve the productivity of ruminant animals and increase the quality of meat by increasing the productivity of ruminants and the profits of farmers and processing businesses by enabling safe supply of ruminant vitamin C to ruminants. The present invention relates to a feed additive, a production method and use thereof.

  The amount of vitamin C required for beef cattle has not yet been clarified and is known as an essential ingredient in studies on some livestock. However, since most vitamin C is decomposed in the ruminant ruminant, the development of technology to protect it from being broken down in the rumen so that it can be absorbed through the small intestine and used in the small intestine. is necessary.

  In particular, when vitamin C deficiency is a typical symptom, it responds sensitively to reduced resistance to disease and stress from the external environment. Such supplementation of vitamin C affects the promotion of intramuscular adipocyte differentiation, immunity enhancement by antioxidant action, high temperature and overcoming labor stress, but vitamin C supplemented to the diet is mostly in the rumen. Reported to be degraded.

  The meat color of beef cattle is determined by the presence of myoglobin, and the content of these three types of myoglobin is determined by metabolic action, pH, contact time with air, and the like. In particular, the phenomenon of meat color decline is promoted by the oxidative effect in the air, but this is achieved by supplying vitamin C, which is a physiologically active substance that acts as an antioxidant by reducing stress due to the nutritional status of beef cattle before slaughter. Such phenomenon can be reduced.

  For this reason, the inventor has invented a coated vitamin C which is stable against rumen degradation and can be supplied to ruminants. Vitamin C is an essential nutrient component in livestock, but in the case of ruminants, technology has been devised to prevent vitamin C from being decomposed in the rumen for a long time because it is decomposed in the rumen and cannot obtain its efficacy. .

  For example, Patent W002 / 0567704A1 clearly shows that vitamin C is supplied to increase the marbling effect of beef cattle. In particular, when vitamin C coated with hardened soybean oil so as to be stable in the rumen is fed, it is clearly shown that there is an excellent effect on meat color and meat quality as compared with the non-vitamin C non-feeding control group. However, there is a disadvantage in that the safety of the coating substance is lowered during the distribution process when the amount of hydrogenated soybean oil used as the coating lipid is small and the rumen bypass rate is reduced.

  Further, US Pat. No. 4,808,412 discloses a technique for protecting a physiologically active substance using a polymer substance for rumen protection. Because there are so many, there is a disadvantage that the unit price becomes high at the time of commercialization.

  Korean Patent No. 10-491164 discloses a method for feeding vitamins C and B mixed with minerals for the purpose of preventing beef color reduction in beef cattle. The disadvantage is the lack of rumen protection technology that allows it to pass stably without being broken down in the stomach.

  In addition to the above patents, there are patents for preventing the bioactive substances from being decomposed in the rumen, but most of them have some disadvantages or practical effects when actually commercialized.

However, in practice, there is Roche Vitamin C for ruminants. This product is a product in which vitamin C is phosphated and coated with cellulose, but because it is a derivative rather than vitamin C itself, the absorption rate will drop and the rumen bypass rate will also drop, so that in order to obtain an excellent effect when actually paid There is a disadvantage that you have to use too much. In addition, the price of the product is high, and there is a problem that it cannot be used widely due to the burden on the farmers.
U.S. Pat. No. 4,808,412 Korean Registered Patent No. 10-491164

  Here, the present inventors digested the lower part of the ruminant so that vitamin C, which was not easily decomposed in the ruminant of the ruminant and could not see the effect of supplying vitamin C, was stabilized in the rumen without being decomposed by microorganisms, pH and moisture. As a result of diversified research on the production of rumen-protecting vitamin C so that it can be absorbed and absorbed into organs, vitamins in the rumen are used when performing a two-step encapsulation process using specific preparation. It was confirmed that C was protected and there was an effect of increasing the productivity of ruminants, and the invention was completed.

  It is an object of the present invention to provide a feed additive for ruminant feeding that has an excellent rumen bypass rate and protects vitamin C, and a method for producing the same. Another object of the present invention is to provide a method for improving the meat quality by feeding a ruminant with a feed additive for ruminant feeding in which the vitamin C is protected.

In order to achieve the above object, the present invention provides vitamin C , a primary capsule layer in which the vitamin C is primary-encapsulated with a binding coating agent , and an oil / fat whose surface of the primary capsule layer is extremely hardened ( iodine value is 1.0). Hereinafter, a feed additive for ruminant feeding that protects vitamin C including a secondary capsule layer that is secondarily encapsulated at a melting point of 57 ° C. or higher) is characterized.

The present invention also provides
a) a primary encapsulation step in which a primary capsule layer is formed by coating the vitamin C with a binding coating agent; and b) an oil and fat ( iodine number is 1) obtained by extremely curing the primary encapsulated substance. 0.0 or less, melting point of 57 ° C. or more), characterized by a method for producing a feed additive for ruminant feeding, in which vitamin C is protected, including a step of performing secondary encapsulation to form a secondary capsule layer .

  In addition, the present invention is characterized by improving the meat quantity and meat quality of ruminants by adding the feed additive for ruminant feeding that protects the vitamin C to the ruminant feed and supplying it to the ruminants. .

  When the product of the present invention is fed to ruminants, vitamin C is protected in the ruminant stomach and can be used by efficiently adding vitamin C to the feed, contributing to increased productivity and the effect of vitamin C. Can produce high quality livestock products.

The present invention will be described in detail below. The feed additive for ruminant feeding according to the present invention in which ruminant C is protected includes a primary capsule layer in which vitamin C is primary-encapsulated with a binding coating agent, and an oil and fat ( iodine) whose surface is extremely hardened. And a secondary capsule layer that is secondary encapsulated with a value of 1.0 or less and a melting point of 57 ° C. or more.

  The feed additive eliminates the problem of decomposition by microorganisms, pH and moisture in ruminant ruminants when vitamin C is supplied to ruminants by encapsulating the surface of vitamin C in two layers. C can safely move to the lower digestive tract and be absorbed.

As vitamin C, ascorbic acid and its derivatives are possible, and these are used alone or in combination. The primary capsule layer is injection coated with a mixture of binder and coating, and the product thus coated forms a capsule layer that stabilizes vitamin C from heat and pressure .

  Such bond coatings include biswax, a polymer selected from the group consisting of PG, PEG, and combinations thereof, surfactants, calcium stearate, zinc stearate, magnesium stearate, and the like. One kind selected from the group consisting of divalent soap selected from the group consisting of combinations, hardened oil, extremely hardened oil, liquid fructose, cellulose, silica and combinations thereof is possible.

The secondary capsules layers makes us allow bypassed to the lower gastrointestinal organs to be stable absorption and digestion with the role that will enhance the safety of the primary encapsulated product on rumen. As the secondary capsule layer, an extremely hardened oil and fat having an iodine value of 1.0 or less and a melting point of 57 ° C. or more can be used . Typically, in the extremely hardened oil and fat, hardened vegetable oil, hardened corn oil, hardened cottonseed oil, hardened peanut oil, hardened palm kernel oil , hardened palm oil , hardened palm stearin oil , hardened sunflower oil, hardened rapeseed oil, and combinations thereof One type selected from the group consisting of the above can be used .

The feed additive for ruminant feeding that protects such vitamin C is:
a) a primary encapsulation step in which a primary capsule layer is formed by coating the vitamin C with a binding coating agent; and b) an oil and fat ( iodine number is 1) obtained by extremely curing the primary encapsulated substance. 0.0 or less, melting point is 57 ° C. or more) and is subjected to secondary encapsulation to form a secondary capsule layer.

First, in step a), vitamin C is mixed with a binding coating agent and then primary encapsulated. In the first encapsulation, specifically, a binder is added to a blender at a constant content per 1 part by weight of vitamin C , and the mixture is uniformly mixed. It consists of the process of injection molding with a perforated plate.

As the mixer, a normal mixer, for example, a ribbon mixer, a general stirrer, a homomixer, or a V-shaped mixer is used. At this time, it is desirable that the binder coating agent is mixed in 0.1 to 2 weight units per 1 weight unit of vitamin C. If the amount is less than 0.1 weight unit, the bonding strength is reduced and it is difficult to mold with an extruding machine. If the amount is more than 2 units, the final vitamin C content is reduced. At this time, the meaning of the “weight unit” is the concept of weight. For example, 0.1 weight unit of vitamin C and 0.1 weight unit of the binding coating agent use 0.1 g of the binding coating agent when using 1 g of vitamin C. Means.

  At this time, if necessary, an appropriate amount of water is added to the mixer. The mixture obtained through the mixer is extruded at a temperature of 10 to 60 ° C. using an extruder, and then the primary capsule material in the form of granules or immersion is produced through an injection molding machine.

  At this time, as the extruding machine, an extruding machine (Extruder) or a pull loader (Plodder) which are generally used can be used. Moreover, the said injection molding machine uses the apparatus whose size of a perforated plate is 0.5 mm-2.5 mm in order to encapsulate.

Next, in step b), a secondary capsule layer is formed by coating the primary encapsulated substance with an extremely hardened oil ( iodine number is 1.0 or less, melting point is 57 ° C. or more) to form a secondary capsule layer. Carry out

5 to 80% by weight of primary capsule material 20 to 95% by weight and extremely hardened oil and fat ( iodine value is 1.0 or less, melting point is 57 ° C. or more) to form a secondary capsule layer Mix at%. If the content of the secondary capsule material is less than the above range, the secondary capsule layer is so thin that the feed additive is dissolved in the rumen and vitamin C is decomposed. On the other hand, if the content exceeds the above range, the secondary capsule layer is so thick that it is difficult to absorb vitamin C in the lower digestive tract.

  The mixed mixture is subjected to secondary encapsulation using an encapsulating apparatus such as a high speed mixer, a ribbon mixer, or a fluidized bed process machine. At this time, a specific method is not limited in the present invention, and a known capsule process is followed.

The feed additive according to the present invention manufactured through the above steps has a structure in which vitamin C is double coated, and can be manufactured by appropriately changing the size depending on the ruminant to be applied. Yes, desirably 0.5 mm or less, more desirably 0.05 to 0.3 mm.

  The manufactured rumen-preserving vitamin C has the advantage that the form is uniform and uniform, and the vitamin C is distributed on the surface because it undergoes a secondary coating process in addition to the primary coating product containing vitamin C. There is an advantage that most of the vitamin C input without possibility can maintain safety. By supplying such feed additives to ruminants, the meat quantity and quality of ruminants are improved.

  In the past, when vitamin C was supplied to ruminants, it was not easily seen in the rumen, but the supply effect of vitamin C produced by the present invention was supplied. In this case, vitamin C is absorbed and transferred to the lower digestive tract so that it is stable in the rumen without being degraded by microorganisms and pH and moisture.

  This increases the efficiency of ruminant use of nutrients to increase productivity, and increases the transfer within the livestock product to enable the production of functional livestock products. The ruminant is not particularly limited in the present invention, and can be any known ruminant, and preferably includes dairy cows, Korean cattle, deer, sheep and the like useful for the livestock industry.

  According to desirable experimental example 3 of the present invention, when a feed additive containing rumen-protecting vitamin C was supplied to Korean beef, the effect of greatly improving the meat amount and quality compared to the control group was confirmed.
