Problems solved by technology

[0003] At present, most acidifier products at home and abroad are single acid preparations (the first generation acidifier products), and a small number of compound acid preparation products (the second generation products) rarely consider the physiological characteristics of animals and the breeding environment, and the use effect is unstable. , the added acid is often neutralized by the alkaline substances in the feed, losing the acidifying effect

preparation example Construction

[0029] The preparation method of described feed compound acidifier, the steps are as follows:

[0030] A. Mix phosphoric acid and citric acid or fumaric acid in proportion, control the temperature at 40-60°C, and stir evenly to obtain an organic acid solution;

[0031] B. Add sodium diacetate into the organic acid solution, control the temperature at 40-60° C., and obtain the compound acidifier for feed after the sodium diacetate is fully dissolved.

[0032] The use of the compound acidifier for feed is used as a compound acidifier for livestock and poultry.

[0033] The livestock and poultry are early weaned piglets or chickens, and the following are mainly early weaned piglets as an example.

Embodiment 1

[0035] At 40°C, fully mix 40kg of phosphoric acid and 35kg of citric acid, stir evenly, add 25kg of sodium diacetate into the compound acid solution, stir, control the temperature at 50°C, and dissolve fully.

Embodiment 2

[0037] At 40°C, fully mix 40kg of phosphoric acid and 35kg of fumaric acid, stir evenly, add 25kg of sodium diacetate into the compound acid solution, stir, control the temperature at 50°C, and dissolve fully.

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

technical field [0001] The invention relates to a compound acidifier for feed and its preparation method and application. Background technique [0002] In order to maximize the annual production capacity of sows and make full use of expensive farrowing room facilities, early weaning has been widely used in modern pig production, that is, piglets are weaned at 3 to 5 weeks of age. After weaning, piglets often have poor appetite, indigestion, slow growth, low feed utilization, decreased disease resistance, and poor mental status. These are collectively referred to as early weaning syndrome. Adding acidifiers in the feed can reduce the pH value of the gastrointestinal tract, promote the digestion and absorption of nutrients, inhibit the reproduction of harmful microorganisms in the intestinal tract, promote the growth of animals, increase the metabolic rate, improve immune function, and reduce stress. It has important practical value in production. [0003] At present, most a...
