Embodiment 1

[0012] (1) Activation of various strains, composition of shake flask culture medium and shake flask culture conditions

[0013] Rhodopseudomonas palustris activation and shake flask medium composition: NH 4 Cl1.0g, CH 3 COONa3.5g, MgCl 2 0.1g, CaCl 2 0.1g, KH 2 PO 4 0.6g, K 2 HPO 4 0.4g, yeast extract 0.1g, water 1000ml, pH7.5. Shake flask culture conditions: temperature 30°C, 72 hours; light 3000lx;

[0014] Bacillus subtilis activation and shake flask medium composition: 5 grams of beef extract, 5 grams of peptone, 5 grams of NaCl, 1 gram of yeast powder, 0.2 grams of calcium carbonate, MgSO 4 0.5 grams, 1000ml of tap water, PH=7.0-7.5; shake flask culture conditions: temperature 35°C, 220 rpm, 24 hours;

[0015] Lactobacillus acidophilus activation and shake flask medium composition: MRS modified medium (peptone 10g, yeast extract 5g, beef extract 10g, glucose 20g, sodium acetate 5g, sodium citrate 2.15g, soil temperature 801ml, MgSO 4 ·7H 2 O 0.58 g, MnSO 4 4H ...

Embodiment 2

[0026] The medium and culture conditions of each strain are the same as above. After activation, shake flask culture, primary expansion, and secondary expansion culture of each bacterial strain, the ratio of the number of bacteria is as follows: Rhodopseudomonas palustris: Bacillus subtilis: acidophilus Lactobacillus: Candida genus: Bacillus natto = 4: 12: 10: 4: 2 for mixing, then add adsorbent to the mixed fermentation broth for adsorption and drying to obtain the product. The composition and weight ratio of the adsorbent are rice bran:wheat bran:soybean meal=1:1:1.

[0027] The beneficial effects of the compound probiotics for broiler chickens of the present invention will be further described in conjunction with the efficacy experiment on broiler chickens.

Abstract

The invention discloses a composite microecological preparation for broiler chickens. The composite microecological preparation is composed of a composite strain fermentation liquid and an adsorbent. 12-20L of the composite strain fermentation liquid is added into every 100kg of the adsorbent. The adsorbent comprises rice bran, wheat bran and soybean meal in a weight ratio of 1:1:1. The composite microecological preparation for broiler chickens has a beneficial viable count of greater than or equal to 1billion / g. The composite strain fermentation liquid comprises Rhodopseudomonas palustris, Bacillus subtilis, Lactobacillus acidophilus, Candida utilis and Bacillus Natto in a number ratio of 3-5:10-15:8-12:3-5:1-3. The microecological preparation prepared from a variety of beneficial bacteria provided by the invention has the efficacy of keeping the balance of intestinal flora, improving feed conversion and utilization rate, and enhancing the digestive absorption ability of animals, thereby reducing the cost and improving economic benefits.

Description

technical field [0001] The invention relates to a compound microecological preparation for broilers, which belongs to the technical field of feed. Background technique [0002] With the development of large-scale, intensified and factory production methods of animal husbandry, and the gradual exposure of the shortcomings of antibiotics (leading to the imbalance of bacterial flora in the body, the development of drug resistance and poor palatability of livestock products), people have gradually realized that: maintaining intestinal bacteria Herd balance and stability are necessary for good health and normal performance of livestock. [0003] At present, due to the influence of feeding methods and feeding environment, broiler chickens encounter the following situations, such as: poor ventilation in the chicken house, leaking drinking fountains, damp litter, contaminated feed, and encountering emergency or antibacterial treatment, which will lead to an imbalance of flora. An u...
