Embodiment 1

[0011] The preparation of embodiment one Polygonum caperica extract

[0012] Materials and Methods

[0013] 1. The source and pretreatment of Polygonum sp.

[0014] Spicy Polygonum is collected from Guanghan City, Sichuan Province, China, and the whole plant is dried in the shade. Before extraction, place the shade-dried Polygonum punctatus in an oven at 60-70°C to dry for later use.

[0015] 2. Preparation of Polygonum capsicum extract

[0016] 2.1 Lab preparation of Polygonum extract. Cut the dried whole herb of Polygonum officinale into a length of about 0.2-0.5cm, then weigh 100g, add 0.5L of distilled water, soak for 30 minutes, boil in an open container, and decoct with low heat for 15 minutes. Use 4 layers of gauze to filter the medicinal solution; add 0.3L of water to the remaining medicinal residues, boil and simmer for 15 minutes, filter the medicinal solution with 4 layers of gauze; then add 0.2L of water to the remaining medicinal residues, boil and simmer for ...

Embodiment 2

[0019] The bacteriostatic test of embodiment two peppery Polygonum extracts to typical pathogenic bacteria of chicken intestinal tract in vitro

[0020] Polygonum is usually used as a medicine for treating intestinal diseases in the folk pharmacopoeia, indicating that the active ingredients in it may inhibit or kill the growth of intestinal microorganisms. Therefore, this experiment selected three typical enteric pathogenic bacteria as representatives, and investigated whether the extract of Polygonum punctatus had any effect on these bacteria in vitro.

[0021] 1. Materials and methods

[0022] 1 strain

[0023] Staphylococcus aureus; Escherichia coli ATCC25922; Salmonella pullorum. The above strains were provided by the Department of Poultry Diseases, Sichuan Agricultural University.

[0024] 2 media

[0025] Ordinary nutrient broth, nutrient agar medium, configured according to conventional methods [Li Yinglin. Culture medium manual. Jilin: Jilin Science and Technology ...

Embodiment 3

[0039] EXAMPLES Effects of Polygonum saponica Extract on Typical Microorganisms in Broiler Gut and Mortality of Broiler Chickens

[0040] 1 Experimental design

[0041] A single factor experimental design was adopted, with 3 treatments and 4 repetitions for each treatment. Each treatment is as follows:

[0042] Treatment 1: Control group (feeding basal diet without antibiotics)

[0043] Treatment 2: Low-dose Polygonum Polygonum Addition Group (Basic Diet + 0.2wt% Polygonum Polygonum Extract)

[0044] Treatment 3: High-dose Polygonum Polygonum Addition Group (Basic Diet + 0.4wt% Polygonum Polygonum Extract)

[0045] 2 Experimental animals and grouping

[0046] In the experiment, 110 Aviin broilers were selected. They were not divided into groups at the age of 0-21 days, and they were all fed the same brooding feed, in order to establish a relatively stable intestinal microbial flora in the broilers in the same environment. After weighing at the age of 21 days, a total of 9...

Abstract

The invention discloses a broiler feed additive and a preparation method thereof. The method comprises the following steps of: taking whole red-knees herb, cutting into 0.2-0.5cm long, adding water according to the ratio of 1:5(g/ml), immersing for 30min, boiling, decocting for 15min by soft fire, and filtering liquid medicine by four layers of gauze; adding water into remaining slag according to the ratio of 1: (2-3) (g/ml), boiling, decocting for 15min by soft fire, and filtering; adding water into filter residue according to the ratio of 1: (2-3) (g/ml), boiling, decocting for 15min by soft fire, and filtering; and combining the liquid medicine of the three times, concentrating to be paste by soft fire, and drying the paste by a freezer drier, thereby obtaining the extract. Through broiler raising tests, two adding levels are set according to the minimal inhibitory concentration obtained by an in-vitro method. The results show that the adding level is 0.2wt% to 0.4wt%. By adoption of the preparation method, the death rate of the broiler can be reduced, the amount of beneficial bacteria (represented as lactic acid bacteria and bifidobacterium) in ileum and caecum is improved, and meanwhile, the amount of harmful bacteria (represented as escherichia coli) is reduced.

Description

technical field [0001] The invention relates to the technical field of poultry feeding, in particular to a broiler feed additive and a preparation method thereof. Background technique [0002] In modern farming, in order to improve the survival rate, production performance and disease resistance of broilers, antibiotics are often added to the feed, but this also brings about bacterial resistance and food safety problems. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a broiler feed additive and a preparation method thereof. [0004] Technical scheme of the present invention is as follows: [0005] A preparation method of feed additive for broiler chickens, which comprises the following steps: taking the whole herb of Polygonum capsicum (both hay and fresh grass can be used), cutting it into 0.2-0.5 cm in length, adding water according to the ratio of 1:5 (g / ml), soaking for 30 minutes, and boiling Simmer for 15 minu...
