Problems solved by technology

[0003] Existing diets for weaned piglets have certain disadvantages when used, and cannot improve the growth performance of piglets very well. They are prone to weaning diarrhea, intestinal morphology, blood routine and serum biochemical indicators, which is not conducive to people's use. It has brought certain adverse effects to people's use process. Therefore, we propose a probiotic preparation that promotes the growth of piglets and improves their intestinal tract and its preparation method

preparation example Construction

[0025] The preparation method of the probiotic preparation for promoting the growth of piglets and improving their intestinal tract is characterized in that it comprises the following steps:

[0026] S1: Select a certain number of strains, the strains adopt different types, and the strains mainly exist in various foods such as fermented meat products and dairy products, among which fermented meat products are one of the important sources of bacteriocin-producing strains;

[0027] S2: Select different culture media, the culture media mainly include Enterococcus faecium YS01 culture medium and Clostridium butyricum YS08 culture medium, and different strains are inoculated in the corresponding culture medium;

[0028] S3: Cultivate the bacterial strain under suitable conditions, cultivate the bacterial strain to about 1011 CFU / ml, then expand the cultivation with a fermenter, perform centrifugation on the bacterial strain at room temperature, and collect the bacterial cells;

Embodiment

[0035]Select 48 28-day-old triple hybrid pigs (Du×Long×Da) with similar farrowing period and litter size, same parity, and similar body weight, and randomly divide them into three groups, with 4 repeated pens in each group, and 4 Head (2 males and females each), fed the same diet after weaning, with different additives, and the experimental period was 21 days in total, and the disease and treatment were recorded;

[0036] The weaned piglets were divided into two groups: the control group and the probiotic compound preparation; the basal diet was corn-soybean meal basal ration, the control group added 1g whey powder / kg basal ration, and the experimental group was EBS and EC probiotic compound The preparation is to mix different probiotic compound preparation groups into the diet with whey powder as the carrier, and the added amount is 1g probiotic compound preparation / kg basic diet;

[0037] Determine the body weight (BW) and ration remaining of the weaned piglets every day, ca...

Abstract

The invention discloses a probiotic preparation for promoting growth and improving intestinal tracts of piglets and a preparation method thereof, the probiotic preparation comprises the following raw materials: a commercial complex probiotic product EBS and an autonomous complex probiotic EC, the commercial complex probiotic product EBS comprises enterococcus faecalis S1, bacillus subtilis 45 and Saccharomyces cerevisiae 1, the autonomous complex probiotics EC comprise Enterococcus faecalis YS01 and Clostridium butyricum YS08. According to the probiotic preparation for promoting growth and improving intestinal tracts of piglets and the preparation method thereof, the complex probiotic preparation containing enterococcus faecium for producing bacteriocin and clostridium butyricum is added into daily ration of weaned piglets, and the influence of the complex probiotic preparation on improvement of growth performance, weaning diarrhea, intestinal morphology, blood routine and serum biochemical indexes of the piglets is measured; and compared with commercial strains, the probiotic preparation can be used as a substitute of antibiotic to be added into daily ration to improve the production performance of piglets and relieve the problems of weaning diarrhea, intestinal injury and the like, and brings a better use prospect.

Description

technical field [0001] The invention relates to the field of animal breeding, in particular to a probiotic preparation for promoting the growth of piglets and improving their intestines and a preparation method thereof. Background technique [0002] Probiotic preparations, especially compound preparations, are safe and harmless for animal production as additives. At present, many of them have been used as substitutes for antibiotics in commercial farming. Intestinal microbiota and bacterial metabolites can improve the composition of microbiota: prevention and Treatment of intestinal flora imbalance inhibits the invasion and adhesion of pathogenic bacteria to the intestinal tract, maintains or enhances the intestinal barrier function, maintains and restores intestinal health, and promotes intestinal immunity, etc. Many studies have shown that supplementing the diet with Enterococcus faecium can reduce the pH of the intestinal contents of weaned piglets, and can inhibit the nu...
