Problems solved by technology

A single benzoic acid will have the following problems during the addition process: the addition of benzoic acid is small, and the bactericidal effect is poor. Increasing the addition amount will affect the palatability of the entire feed. Therefore, in order to improve the bactericidal effect of the entire product, the market Many acidifiers use benzoic acid and formic acid as the main components. However, although formic acid has a strong antibacterial and bactericidal effect, it is very volatile. If it is directly added to the feed, it will not only cause a lot of loss, but also increase the cost. It is also very irritating. Greatly affects animal feeding
[0005] In order to solve the above problems, the Chinese invention patent application whose application publication number is CN104719630A discloses an acidifier for poultry feed, which solves the volatility of formic acid by formate (calcium formate and potassium formate), but forms Adding acid salts to feed will affect the release of formic acid, greatly reducing the bactericidal effect of the entire acidifier
In addition, the addition of the whole acidifying agent is large and the cost is high

Embodiment 1

[0026] This embodiment provides a broad-spectrum sustained-release acidifier for feed, which includes the following ingredients in parts by weight: 22.5 parts of ammonium formate, 22.5 parts of formic acid, 15 parts of benzoic acid and 40 parts of carrier. The carrier used in this embodiment can be one or more mixtures of silica, sodium sulfate, zeolite powder, montmorillonite, sepiolite, bentonite and medical stone. The preferred carrier of this embodiment is dioxide silicon.

[0027] This embodiment also discloses the preparation method of the broad-spectrum sustained-release acidifier for feed, which specifically includes the following steps:

[0028] S1. Put 39 parts of formic acid into the reaction kettle, start stirring, and slowly feed liquid ammonia into the reaction kettle (while adding, detect the molar ratio of formic acid and ammonium formate in the reaction kettle to prevent excessive liquid ammonia). While adding liquid ammonia, turn on the cooling water to cool...

Embodiment 2

[0039]Example 2 Group 1-Example 2 Group 4

[0040] The difference between Example 2 Group 1-Example 2 Group 4 and Example 1 is that the parts by weight of the ingredients are different, the parts by weight of the ingredients in Example 2 Group 1-Example 2 Group 4, and the obtained broad-spectrum sustained-release acidification Please refer to the following table for the specific usage of the agent:

[0041]

[0042] A total of 240 three-way weaned piglets aged 25 days, with basically the same body weight and good health were selected and randomly divided into 6 treatments, each treatment had 4 replicates, and each replicate had 10 pigs. The control group is a blank treatment, fed with a basal ration, and the basal ration is corn+soybean meal type feed; the antibiotic group adds aureomycin and oxytetracycline calcium on the basal ration of the control group; Example 2 Group 1-Example Group 2 and Group 4 added 3000g / t acidulant to the basal diet of the control group, and the...

Abstract

The invention belongs to the technical field of feed additives, and particularly discloses a broad-spectrum slow-release acidifier used for feed. The broad-spectrum slow-release acidifier used for thefeed comprises the following components in parts by weight: 10-30 parts of formic acid, 10-30 parts of ammonium formate, 15-30 parts of benzoic acid and 10-65 parts of a carrier. A production methodof the broad-spectrum slow-release acidifier used for the feed is further disclosed. The provided broad-spectrum slow-release acidifier has an excellent sterilization effect, can effectively increasea utilization rate of the feed, reduces an incidence rate of diarrhea of animals, promotes digestion of the feed in the gastrointestinal tracts, inhibits and kills pathogenic microorganisms at the same time, increases the production efficiency of a farm, and can be added into the feed according to a ratio for even mixing during use, an additive amount is low, the raw materials are wide in source and low in price, the cost is low, and industrial production is easy, so that the broad-spectrum slow-release acidifier used for the feed has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a broad-spectrum slow-release acidifier for feed and a preparation method thereof. Background technique [0002] With the introduction of growth-promoting antibiotics in feed, the health level of animals will decline, such as diarrhea and increased mortality (especially in young animals), so there is a need for antibiotics that can act like antibiotics but reduce diarrhea, Antibody replacement products that reduce mortality. [0003] There are many antibiotic replacement products on the market, such as plant extracts, enzyme preparations, acidifiers, microecological preparations, antimicrobial peptides, etc. According to the experience feedback from the industry and the EU, the current antibiotic replacement products are mainly acidifiers , to inhibit and kill harmful bacteria in the gastrointestinal tract, promote the growth and reproduction of beneficial bacteria, reduc...
