Embodiment 1

[0025] Preparation of enzymatic hydrolysis mixture of astragalus, Zanthoxylum bungeanum and honeysuckle with cellulase.

[0026] Mix 40 parts of raw materials astragalus, 25 parts of Zanthoxylum bungeanum, 25 parts of honeysuckle and 10 parts of cellulase, add 60% of the total weight of the mixture for enzymolysis, enzymolysis temperature is 50°C, pH is about 6.0, and fluidization is used after enzymolysis Bed-dried, dried and crushed through a 40-mesh sieve.

Embodiment 2

[0028] Preparation of protease and amylase.

[0029] The protease and amylase derived from Bacillus subtilis FM537 were prepared by the following method: Streak Bacillus subtilis FM537 on LB agar plate, culture overnight at 37°C, pick a single colony and inoculate in 10mL LB medium, 150rpm, overnight at 37°C Cultivate as the primary seed liquid, inoculate the primary seed liquid with 1% inoculum amount into 1000mL improved nutrient broth medium, cultivate overnight at 150rpm, 37°C to obtain the secondary seed liquid, and inoculate the secondary seed liquid with 10% inoculum amount Ferment in 100L of improved nutrient broth medium, 150rpm, 37°C for 30h to obtain fermentation broth, transfer the fermentation broth to a recovery tank, and obtain protease and amylase compound enzymes through plate and frame filtration, ultrafiltration, fine filtration and spray drying, which can be directly As the raw material of the feed additive of the present invention.

Embodiment 3

[0032] A feed additive for preventing and treating chicken glandular gastritis and muscular gastritis, the composition of raw materials in parts by weight is as follows: 15 parts of cellulase enzymolysis mixture of astragalus, Chinese prickly ash and honeysuckle, 18 parts of protease and amylase derived from Bacillus subtilis FM537, Vitamin B 1 14 parts, 60 parts of montmorillonite.

[0033] Animal experiment: 144 1-day-old healthy AA broilers were randomly divided into 2 treatments, each treatment had 6 replicates, and each replicate had 12 chickens. Treatment group 1 is a blank group, fed with basal diet; treatment group 2 is a test group, with 1 kg / T of the additive product of the present invention added to the basal diet. The test period is 42 days. During the test period, the feed amount and remaining feed amount were recorded for each repetition group, and the average daily gain, daily feed intake and feed-to-weight ratio were calculated from this. For the test chick...

Abstract

The invention provides a feed additive for preventing and treating chicken proventriculitis and ventriculitis. The feed additive is prepared from the following raw materials in parts by weight: 10 to 15 parts of cellulose enzymolysis mixture of radix astragali seu hedysari, pepper and honeysuckle flowers, 9 to 18 parts of prolease and amylase, 8 to 14 parts of vitamin B1 and 60 to 75 parts of montmorillonite. The cellulose enzymolysis mixture of radix astragali seu hedysari, pepper and honeysuckle flowers is dried and crushed and is then mixed with the prolease, the amylase, the vitamin B1 and the montmorillonite to be made into the feed additive product of the invention. Through being verified by feeding experiments, the feed additive provided by the invention has the advantages that the production performance of broiler chickens can be obviously improved; the immunologic function of the broiler chickens can be obviously enhanced; the occurrence rate of the chicken proventriculitis and ventriculitis is reduced; a good cure effect is achieved on the chickens with the proventriculitis and ventriculitis; the chicken death rate is reduced.

Description

technical field [0001] The invention relates to a feed additive for preventing and treating chicken glandular gastritis and muscle gastritis, and belongs to the technical field of poultry feed and feed additives. Background technique [0002] In recent years, with the development of broiler breeding industry, glandular gastritis and gizzard erosion have developed into common diseases that endanger the poultry breeding industry, bringing greater economic losses to farmers. The clinical symptoms and pathological changes of the disease are not the same, and the etiology of the disease is different. Since the initial report in the Netherlands in 1978, there have been such reports from various countries in the world, and each has different clinical symptoms and pathological changes. In recent years, the incidence of the disease has been on the rise, and the incidence range is wide. It is popular in a large area in my country, and it is popular throughout the year, and it is more...
