Abstract

The invention discloses a compound acidifier for feed, and a preparation method and application of the acidifier. The preparation method of the compound acidifier comprises the following steps of: mixing and stirring phosphoric acid with weight percentage of 40%-50% with citric acid or fumaric acid with weight percentage of 30%-40% at 40 DEG C to 60 DEG C, thus obtaining a uniform compound acid solution; and adding sodium diacetate with weight percentage of 10%-30% to the compound acid solution, thus obtaining the compound acidifier for the feed after sufficiently dissolving and uniformly mixing the sodium diacetate. The compound acidifier for the feed provided by the invention has the simple preparation method and stable quality, is convenient to popularize and apply, can be applied to livestock and in particular early-weaning piglets, and can make up the shortage of gastric acid secretion and improve the digestive absorption capacity of animals to promote the growth of the animals and improve the production performance of the animals.

Description

A kind of feeding compound acidulant and its production and use
Technical field
The present invention relates to a kind of feeding compound acidulant and its production and use.
Background technology
For the yearly productive capacity that improves to greatest extent sow and the delivery room facility that takes full advantage of costliness, generally adopt the early weaning mode in the Pig Industry production, namely piglet is carried out wean when 3~5 age in week.And the situations such as appetite is poor, indigestion, growth is slow, efficiency of feed utilization is low, premunition descends, mental status is not good usually appear behind the weaned piglet, these are referred to as early weaning syndrome.In feed, add acidulant and can reduce intestines and stomach pH value, promote digesting and assimilating of nutriment, suppress the breeding of harmful intestinal tract microorganism, promote the growth of animal, improve metabolic rate, and can improve immunity function, reduce stress, thereby have important practical value in production.
At present, the acidulant product belongs to single acid supplement (first generation acidulant product) mostly both at home and abroad, the Compound-acid formulation products of minority (second generation product) formula Design is seldom considered animal physiological characteristics and feeding environment, result of use is unstable, the acid of adding usually by the neutralization of the alkaline matter in the feed, loses acidizing effect.The compound acidulant piglet successful of feeding is better than single acidulant, can improve the resistance against diseases of piglet, can not develop immunity to drugs again.Therefore can replace the part antibiotic.
Compound acidulant is that several single acidulants are composited according to a certain percentage, and main compound acidulant is complete sour compound acidulant on the market.Complete sour compound acidulant refers to take a certain acid as main active ingredient, cooperates other one or more acid to reach synergistic compound acidulant again.
Summary of the invention
The objective of the invention is provides a kind of feeding compound acidulant and its production and use in order to overcome the deficiencies in the prior art.
Feeding compound acidulant comprises following raw material by mass percentage:
Sodium Diacetate 10~30%,
Citric acid or fumaric acid 30~40%,
Phosphatase 24 0~50%.
Described feeding compound acidulant comprises following raw material by mass percentage:
Sodium Diacetate 20%,
Citric acid or fumaric acid 35%,
Phosphatase 24 5%.
The preparation method of described feeding compound acidulant, step is as follows:
A, phosphoric acid and citric acid or fumaric acid are mixed in proportion, temperature is controlled at 40~60 ℃, stirs, and obtains organic acid soln;
B, sodium Diacetate is joined in the described organic acid soln, temperature is controlled at 40~60 ℃, namely obtains described feeding compound acidulant after sodium Diacetate fully dissolves.
The purposes of described feeding compound acidulant is as the feeding compound acidulant of livestock and poultry.
Beneficial effect of the present invention:
The inventive method is simple, constant product quality, easy to utilize.Do not use any organic solvent and the surfactant harmful to animal, can directly add in the feed as a kind of acidulant, this feeding compound acidulant has higher buffer capacity, avoids animal intestines and stomach acidity to cross great fluctuation process.By the mutual conversion of organic acid and acylate, can keep for a long time stable digestive environments in the stomach and intestine that are.The feeding compound acidulant of the present invention adopts the compound mode of hydrochlorate, overcome the shortcoming of the compound acidulant of full acid, action effect is more remarkable, in animal and fowl fodder or drinking-water, add this product, can remedy the deficiency of gastric acid secretion, thereby the abilities of digestive and absorption that improves animal promotes the growth of animal to improve production performance.Feeding compound acidulant of the present invention is applicable to pig, fowl, and early-weaned piglets especially makes an addition to by a certain percentage in feed or the drinking-water according to the needs of different animals and to get final product.
The specific embodiment
The present invention is further illustrated below in conjunction with embodiment, but embodiments of the present invention are not limited to following several embodiment.
Feeding compound acidulant comprises following raw material by mass percentage:
