preparation example Construction

[0022] The present invention provides the preparation method of the feed acidifier described in the above scheme, comprising:

[0023] The formic acid, ammonium formate, acetic acid and ammonium acetate are mixed to obtain the acidulant for feed.

[0024] The method of mixing the formic acid, ammonium formate, acetic acid and ammonium acetate is not specially regulated in the present invention, and the mixing method well known to those skilled in the art can be used to mix the raw materials evenly.

[0025] The present invention also provides the application of the feed acidifier described in the above scheme in pig feed.

[0026] In the present invention, there is no special regulation on the application method of the feed acidifier in the pig feed, and the acidifier can be added to the pig feed according to the addition method well known to those skilled in the art.

[0027] In the present invention, the addition amount of the feed acidifier in pig feed is preferably 1-6 kg...

Embodiment 1

[0031] Acidifier raw materials: 6 parts of formic acid, 5 parts of ammonium formate, 1 part of acetic acid and 1 part of ammonium acetate.

[0032] Preparation method: mix the above-mentioned formic acid, ammonium formate, acetic acid and acetic acid in parts by weight, and stir evenly to obtain the acidulant.

[0033] Verify the buffering capacity of the above acidifiers:

[0034] Put the acidulant prepared in Example 1 into a beaker, add water according to the volume ratio of 1:100, and stir to obtain a mixed solution, stand still for 5min, and measure the pH value of the mixed solution at this time with a pH meter, and obtain the mixed solution at this time The solution is recorded as 1%;

[0035] Put the 1% diluted solution obtained in the above steps into a beaker, add water at a ratio of 1:2, that is, dilute 2 times, and stir evenly to obtain a mixed solution, stand still for 5 minutes, and measure the mixed solution at this time with a pH meter pH value, the solution ...

Embodiment 2

[0043] The general basal diet for weaned piglets was used, and the experimental diets with different acidifiers were prepared according to the experimental design. Prepare test rations according to requirements: control group: basal ration (blank control group); market group: basal ration+market mainstream product group, add by 4kg / t; embodiment 1 group: basal ration+embodiment 1 product , added at 4kg / t.

[0044]60 healthy weaned piglets were selected and randomly divided into 3 treatments according to the principle of similar body weight (the initial weight difference was not significant P<0.05) and half male and half female piglets. The pigs were allowed to eat and drink freely, and other feeding and management were carried out as usual. During the experiment, the defecation, urination, feeding regularity and mental state of the piglets were observed. The piglets in each group were weighed at the beginning and end of the experiment, and the feed consumption was counted. At...

Abstract

The invention relates to the technical field of animal husbandry feed additives, and provides an acidifier for a feed, which comprises the following components in parts by weight: 5.8-6.2 parts of formic acid, 4.9-5.1 parts of ammonium formate, 0.9-1.1 parts of acetic acid and 0.9-1.1 parts of ammonium acetate. A principle that organic acid and ammonium salt thereof form a conjugate pair and interact to maintain balance is utilized, so that weak acid in the acidifier is prevented from being excessively decomposed before entering the gastrointestinal tract of an animal. After the acidifier enters the gastrointestinal tract of the animal, the formic acid and the acetic acid can kill pathogenic microorganisms in the gastrointestinal tract, regulate the species of the intestinal microorganisms and promote the growth and reproduction of beneficial bacteria, so that the diarrhea occurrence rate of piglets is reduced; in addition, the acidifier in the formula is good in palatability; and the single-day food intake of the piglets can be increased. Therefore, the acidifier provided by the invention has the dual advantages of good control effect on diarrhea of the piglets and high weight gain efficiency of the piglets.

Description

technical field [0001] The invention relates to the technical field of livestock feed additives, in particular to an acidifier for feed and its preparation method and application. Background technique [0002] The physiological and biochemical functions of the piglets are not fully developed, and the ingested feed cannot be effectively decomposed and utilized, which may easily cause the occurrence of various physiological obstacles at this stage and affect the production of the aquaculture industry. During the weaning stage of piglets, the ability of the stomach to secrete gastric acid is very limited. Before the age of 60 days, it is difficult for piglets to rely on the gastric acid secreted by their own stomach to control the pH value of the stomach in an appropriate range. On the one hand, it will cause incomplete digestion of feed, resulting in waste of feed; on the other hand, undigested protein reaches the intestinal tract, which will cause diarrhea in piglets and caus...
