Problems solved by technology

This form of butyrate will be rapidly decomposed and absorbed in the front part of the intestine, making it difficult for an effective amount of butyrate to reach the back part of the intestine, which greatly reduces the protective effect of the intestine
In order to solve the problem that it is decomposed and absorbed in the front part of the intestine and cannot reach the back part of the intestine, at present, the coating technology is mainly used to control the release of sodium butyrate, but this method is complicated in process and high in cost

Embodiment 1

[0026] A certain amount of zeolite (the content of clinoptilolite in the zeolite is 86%) was weighed and activated in a 350° C. Maof furnace for 3 hours, and then placed in a thermostat for use.

[0027] Prepare 4mol / L butyric acid solution, mix zeolite and butyric acid according to the ratio of 1:14 (the percentage of 4mol / L butyric acid solution is 93.3%, the percentage of zeolite is 6.67%) and place in a magnetic stirrer to heat and stir (The temperature is controlled at about 60°C), the rotating speed is 120 rpm, and the heating and stirring time is 4 hours. After the reaction, let it stand, wash off the unloaded acid ions with distilled water, and filter the solution until the filtrate is neutral. The separated solid material is dried at 90-105° C., and the dried solid material is input into a pulverizer for pulverization, and the particle fineness after pulverization is ≤0.074 mm to obtain zeolite butyric acid powder. ZRY-2P comprehensive thermal analysis instrument was...

Embodiment 2

[0028] The animal test of embodiment 2 zeolite butyric acid powder

[0029]In order to verify the application effect of sustained-release butyric acid in broiler chicken production, the zeolite butyric acid powder prepared according to the method in Example 2 was subjected to a broiler chicken feeding test. 288 AA broilers of the same breed were randomly divided into 6 groups, with 6 repetitions in each group and 8 chickens in each repetition: the first group was the control group, fed the basal diet; the second group added 0.05 % sodium butyrate, the third group added 1% clinoptilolite on the basis of the basic diet, and the fourth to sixth groups added 0.5%, 1%, and 2% zeolite butyric acid powder on the basis of the basic diet , the test period is 21d. The chicken coop was thoroughly cleaned and disinfected before the experiment. Feeds were fed regularly, twice a day. During the test, the mental state of the flock was observed, and the daily feed intake of the test chicke...

Abstract

The invention discloses a zeolite butyric acid powder, its preparation method and application. A zeolite butyric acid powder, the zeolite powder is composed of 96-99wt% zeolite and 1-4wt% butyric acid; it can be prepared by the following method: 89wt%-94wt% of 1-7mol / L butyric acid solution and After mixing 6wt% to 11wt% of activated zeolite, heat and stir in a magnetic stirrer for 2 to 5 hours, let stand, wash, filter, dry the separated solid material, and crush the dried material to fine particles Degree ≤ 0.1 mm, that is, the prepared zeolite butyric acid powder. The powder solves the volatility of butyric acid and the rancid smell of cheese, and prevents it from being decomposed and absorbed in the front part of the intestinal tract of animals. Adding 0.5% to 2% zeolite butyric acid powder to the feed can improve the production performance of broilers and promote intestinal tract It can improve the growth and development of the intestinal tract, improve the antioxidant function, regulate the microecology of the gastrointestinal tract and protect the intestinal morphology.

Description

technical field [0001] The invention belongs to the field of feed source active substances, and in particular relates to a zeolite butyric acid powder and a preparation method and application thereof. Background technique [0002] The intestinal tract is the largest digestive organ and immune organ in animals. The health and integrity of the intestinal tract is particularly important for the development of animal performance potential and health. However, the intestinal tract is easily damaged by ingested organic and toxic substances, which will damage the protective barrier of the body and affect the normal digestion and absorption of feed by animals. In severe cases, it will lead to bacterial translocation and intestinal dysfunction. For a long time, the control of feed and environmental pollution in production has mainly relied on the use of antibiotics. As a drug with significant antibacterial and antibacterial effects, antibiotics have been widely used in livestock and...
