Embodiment 1

[0043] Embodiment 1, the extraction of versicolor polysaccharide

[0044] Take the dried versicolor versicolor and add 50 times the weight of water to mix, extract at 80°C for 4 hours, take the supernatant and concentrate in vacuo, precipitate with 95% ethanol with 5 times the volume of the concentrated solution, dissolve the precipitate in an appropriate amount of water, and use Deproteinize by Sevag method, precipitate with appropriate amount of 95% ethanol, and dry in vacuum to obtain polysaccharides from Yunzhi.

Embodiment 2

[0045] Embodiment 2, the preparation of feed additive

[0046]Get 50 parts by weight of bone meal and 5 parts by weight of lysozyme, and mix them to make feed additive A1.

[0047] Take 50 parts by weight of bone meal and 5 parts by weight of polysaccharide polysaccharide prepared in Example 1, and mix them to make feed additive A2.

[0048] Take 50 parts by weight of bone meal, 4 parts by weight of lysozyme, and 1 part by weight of polysaccharide polysaccharide prepared in Example 1, and mix them to prepare feed additive A3 with a weight ratio of lysozyme and polysaccharide polysaccharide of 4:1.

[0049] Take 50 parts by weight of bone meal, 2.5 parts by weight of lysozyme, and 2.5 parts by weight of polysaccharide polysaccharide prepared in Example 1, and mix them to prepare feed additive A4 with a weight ratio of 1:1 between lysozyme and polysaccharide polysaccharide.

[0050] Take 50 parts by weight of bone powder, 1.25 parts by weight of lysozyme, and 3.75 parts by weig...

Embodiment 3

[0053] Example 3, the application of the feed additive comprising lysozyme and Yunzhi polysaccharide in the prevention and treatment of swine diarrhea

[0054] In order to verify the application effect of the present invention, the feed additive of the present invention is tested in healthy piglets with similar body weights. The pigs were divided into experimental groups (A1-A6) and control groups, with 50 pigs in each group. Among them, the diet of the experimental group was added with the above-mentioned feed additive according to 1% of the total weight of the feed, the diet of the control group was pig feed of the same weight without adding the above-mentioned feed additive, and the pigs in each group were fed 3 times a day. Feed ad libitum and provide sufficient drinking water at the same time. Other daily management measures are carried out according to the routine management of the farm, and immunization and deworming are carried out regularly. Pig diarrhea rate in each...

Abstract

The invention relates to a feed additive for preventing and curing porcine diarrhea. The feed additive is mainly prepared from, by weight, 50-100 parts of bone meal, 1-10 parts of lysozyme and 1-10 parts of coriolus versicohr polysaccharide. Compared with an ordinary feed additive, according to the feed additive for preventing and curing the porcine diarrhea, a preparation method of the livestock biological feed additive is simple, compatibility is reasonable, the curative effect is significant, the diarrhea rate of livestock can be obviously decreased, and it is proved through experiments that the feed additive has the special effect on preventing and curing the porcine diarrhea; due to the fact that the additive does not contain western medicine components, the feed additive does not have toxic and side effect, the drug resistance does not exist, and pollution does not exist.

Description

technical field [0001] The invention relates to the field of feed, in particular to a livestock feed additive and its application. Background technique [0002] Animal feed additives refer to small or trace substances added during the production, processing and use of animal feed. They are used in small amounts in animal feed but have significant effects. Animal feed additives are inevitable raw materials used in the modern animal feed industry. They have obvious effects on strengthening the nutritional value of basic animal feed, improving animal production performance, ensuring animal health, saving animal feed costs, and improving animal product quality. [0003] Porcine diarrheal disease is caused by a virus in pigs and can affect pigs of all ages. Suckling pigs, shelf pigs or fattening pigs have a high incidence rate, especially suckling pigs suffer the most, and the incidence rate of sows varies greatly, about 15-90%. Sick pigs are the main source of infection. The ...
