Abstract
The invention discloses application of an organic compound. The technical characteristic is as follows: the application objects of triglyceryl lactate as a feed acidifier include monogastric animals such as pigs, poultry and the like, ruminants such as cows, sheep and the like, herbivores such as horses, rabbits and the like or fishes, shrimps and crabs. The application method comprises the following steps of: directly adding 0.05-1.0% of the triglyceryl lactate into the feed based on the total weight of the feed; or mixing the triglyceryl lactate with an adsorbent to obtain a premix; or mixing the triglyceryl lactate with other feed additives or feed raw materials to obtain a premix or a concentrate to feed monogastric animals such as pigs, poultry and the like, ruminants such as cows, sheep and the like, herbivores such as horses, rabbits and the like and aquatic animals such as fishes, shrimps, crabs and the like. Through the invention, the triglyceryl lactate is slowly decomposed in the alimentary canals of animals while releasing the characteristics of lactic acid, the pH value of the gastrointestinal tract is reduced, the growth of harmful bacteria in the gastrointestinal tract is suppressed, the reproduction of beneficial bacteria is promoted, and an effect of improving gastrointestinal microecology of animals is realized so as to promote the animal health and improve the production performance.
Description
Technical field
The present invention relates to the purposes of three glyceride lactates, relate in particular to the purposes in animal feed acidulant field.
Background technology
Add acidulant in feed and can reduce animal gastrointestinal tract pH value, promote digesting and assimilating of nutriment, suppress the breeding of harmful intestinal tract microorganism, improve the animal body immunocompetence, minimizing stress, the promotion growth of animal.Existing fodder acidulant mainly is made of inorganic acid and organic acid, so this class acidulant exists easily at the animal stomach and is absorbed and can not effectively arrives the shortcoming of hindgut.In order to make acidulant effectively arrive hindgut, the coating techniques that adopt solve more at present, and the cost of this technology is higher, coating rate is unstable, thereby has hindered the marketing of this series products.Therefore, the fodder acidulant that need to seek to be more suitable for is used for reducing animal gastrointestinal tract pH value, promotes the micro ecology of gastrointestinal tract balance, and prevention animal intestinal bacteriosis improves cultivation efficient.
Under field conditions (factors), lactic acid in alimentary canal is mainly produced through the anaerobic bacteria glycolysis in the animal hindgut by carbohydrate such as the lactose in feed, SNSPs, it not only provides energy for rat gut mucosa, can also suppress the pernicious bacterias such as the interior Escherichia coli of enteron aisle, salmonella, promote the growth of the beneficial bacteriums such as lactic acid bacteria.
Lactic acid often directly is used as fodder acidulant and uses, and lactic acid is the feed addictive that country allows use, and main application is exactly acidifying.But lactic acid is after entering alimentary canal, mainly in the anterior absorption of alimentary canal, especially in stomach, therefore be difficult to play a role at alimentary canal rear portion (small intestine back segment, colon or caecum etc.), therefore, lactic acid can not effectively reduce alimentary canal back segment pH, reaches to regulate rear intestinal segment effects of microflora.
Lactic acid and glycerine esterification generate three glyceride lactates, molecular formula, C
12H
20O
9, molecular weight: 308.28, structural formula is:
Existing file shows, three glyceride lactates do not retrieve mainly as grease and NMF the technical scheme that three glyceride lactates are used as the animal feed acidulant.
Summary of the invention
The purpose of this invention is to provide a kind of fodder acidulant.
Technical problem to be solved by this invention is to provide the new purposes of three glyceride lactates, namely as the new application of fodder acidulant.
The technical solution adopted for the present invention to solve the technical problems.Three glyceride lactates meet molecular formula as the application of fodder acidulant, C
12H
20O
9, molecular weight: 308.28, structural formula is:
After three glyceride lactates enter alimentary canal, do not absorb at alimentary canal anterior (in stomach), enter the alimentary canal back segment and resolved into glycerine and lactic acid by the secreted lipase of pancreas.Therefore, three glyceride lactates are slowly decomposed in alimentary canal, and lactic acid is slowly released.Three glyceride lactates have following characteristics, and the first, can not produce in animal body the bad property accumulated and specific reaction; Second, for lactic acid or lactate, the decomposable process of three glyceride lactates is processes of biological slow-released lactic acid, and therefore this lactic acid can arrive rear intestinal segment, performance reduces the rear intestinal pH such as small intestine back segment, colon or caecum, and then promotes the micro ecology of gastrointestinal tract balance.
Three glyceride lactates of the present invention are realized by the following method as the using method of fodder acidulant:
Three glyceride lactates, addition are 0.05%～1.0% of feed gross weight, directly it are added in feed; Or add to again in feed after itself and adsorbent are mixed and made into pre-mixing agent; Also can be mixed and made into the forms such as premix, concentrate feed with other feed addictive or feedstuff adds in feed again.
Three glyceride lactates of the present invention are as the application of fodder acidulant, and application is the aquatic livestocks such as the plant-eating animals such as ruminant, horse rabbit such as the nonruminants such as pig fowl, cattle and sheep of artificial feeding and fish shrimp crab.
The advantage that the present invention has is:
1. three glyceride lactates, under the effect of animal tallow enzyme, catabolite is lactic acid and glycerine in vivo, both is normal metabolite in animal body, and is without any side effects to human and animal's body.
2. three glyceride lactates are as fodder acidulant, and decomposition slowly releases lactic acid in animal alimentary canal, can effectively reduce the pH of alimentary canal back segment, effectively reduce growing of pernicious bacteria, promote the breeding of profitable strain, the regulating intestinal canal microecological balance, thus promote growth of animal.
3. before not being decomposed, it is neutral that three glyceride lactates are, and do not produce excitant and corrosivity effect, and have certain aromatic odor, improves the palatability of feed.
4, before not being decomposed, three glyceride lactates can be avoided feed, and especially in premix, the nutriments such as vitamin, mineral matter must destroy, and avoid the acid corrosion of feed-processing equipment is damaged.
So, three glyceride lactates are fodder acidulants desirable in the animal-breeding process, use three glyceride lactates and slowly decomposed the feature that discharges lactic acid in animal alimentary canal, reduce intestines and stomach pH value, suppress the growth of harmful intestinal tract bacteria, the breeding of promotion beneficial bacterium, reach the effect of improving the little ecology of animal intestinal, and then promote animal health and improve production performance.
