This additive is aimed at the immature characteristics of piglet digestive organs, and provides an additive suitable for piglet feed. This biological feed additive strain is actually a Chinese herbal medicine additive, which cannot provide digestive enzymes and anti-immune substances needed for piglet development. Its application low value
[0003] The development of piglets is a key to the lifelong development of piglets. Piglets have the characteristics of incomplete body temperature regulation, poor resistance to cold stress, incomplete digestive organs, incomplete digestive gland function, lack of innate immunity, and easy to get sick. , The survival rate of piglets is not high under general feeding conditions, and diseases such as dysentery, yellow dysentery, pullorum, and indigestion are more common, which reduces the survival rate of piglets

Embodiment 1
[0036] The first step is to cultivate the strains, use the compound mutagenesis breeding technology to optimize each strain, and carry out the fermentation production performance test:
[0037] (1) Use a UV lamp with a power of 15W to add 3ml of each of the bacterial suspensions of Streptococcus lactis, Saccharomyces cerevisiae, Bacillus subtilis, Bifidobacterium, and Lactobacillus casei to 30cm, respectively, and add starch-free medium. In the bacterial plate, irradiate for 1-3 minutes to culture and count, observe the transparent circle on the starch medium, and select the colony whose diameter of the transparent circle and the colony diameter ratio (HC) > 1.5 are transplanted to the inclined surface of the test tube for cultivation;
[0038] Starch medium: peptone 10g, sodium chloride 5g, beef extract 5g, soluble starch 2g, distilled water 1000ml, agar 15-20g.
[0039] (2) Place 0.5 g of nitrosoguanidine crystals on a 6 mm starch medium plate with bacterial strains, place t...
Embodiment 2
[0054] The first step, with embodiment 1
[0055] Second step, with embodiment 1
[0056] The third step, liquid high-speed culture of bacteria
[0057] (1), each bacterial classification is taken in the following proportions: Streptococcus lactis 20%, Saccharomyces cerevisiae 23%, Bacillus subtilis 16%, Bifidobacterium 26%, Lactobacillus casei 15%;
[0058] (2), strain liquid high-speed culture, with embodiment 1
[0059] Step 4: Solid Synchronous Culture of Compound Bacteria
[0060] Mix the compound microbial agent with carbon source, nitrogen source, inorganic salt and inducer evenly, put it into a closed tank for fermentation, and ferment at 32°C for 8 days, and ferment simultaneously;
[0061] Composition and proportion of solid synchronous medium: green bran 40%, soybean meal 7%, corn flour 10%, molasses 18%, yeast powder 0.8%, magnesium phosphate 0.3%, enzyme inducer 0.1%, sterile water 23.8%; Said enzyme inducer is made up of xylose and sophorose, and its mass rat...

Abstract
The invention relates to a microorganism multienzyme additive for promoting the growth and development of baby pigs, which is characterized in that the additive is formed by composite synchronizing solid fermentation of a composite strain stock solution, carbon source, nitrogen source, inorganic salt and enzyme revulsant. A manufacturing method is that all the strains adopt a composite inducing technology to carry through filtering; a method of synchronizing liquid culture and solid composite culture is adopted to lead all the strains to be cultivated in the same culture medium; the total number of live bacterium reaches 3 billion / g and simultaneously a fermented product is kept completely. The product comprises massive physiological metabolism substances like active enzyme, small peptide, oxidation resistance substances, FAA, vitamins, etc. A specific type for feed preparing particles carries through a double-layer microcapsule peridium treatment on the strains that can not resist heat. The invention has the advantages of promoting the digestive absorption on the feed by the baby pigs, promoting the compound of organism protein and full utilization, increasing the disease resistance and immunological competence of the baby pigs, improving the feed switching rate and the production capacity of cultivated animals, reducing the pollution to the environment caused by animal dejecta. The invention is a green and safe agrotechnical product.
Description
technical field [0001] The invention relates to a microbial multi-enzyme additive for promoting the growth and development of piglets, in particular to a technical product that utilizes a variety of microbial fermentation to produce multi-enzymes, which can promote piglets' ability to digest and absorb, improve immunity, cold stress resistance and survival rate A microbial additive belongs to the technical field of agricultural products. Background technique [0002] At present, the published Chinese patent, the publication number is CN98109067.2, entitled feed additive for piglets, is characterized in that: it contains purslane, wild hawthorn, the content is respectively 15-25% and 10-20%, and also contains 30% - 50% feedable single acid or a mixture of multiple acids, with various flavoring agents, supplemented with adsorbents and glidants, pretreated with various ingredients, mixed and stirred evenly to obtain the finished product. This additive is aimed at the immature ...
