Problems solved by technology

[0004] At present, antibiotics are widely used in livestock and poultry farming to prevent diarrhea and promote growth, but antibiotics not only inhibit pathogenic microorganisms, but also destroy the micro-ecological balance of the digestive tract; some antibiotics remain in livestock products, posing a great threat to human health

Embodiment

[0036] 1 Materials and methods

[0037] 1.1 Test material

[0038] Fecal liquid preparation:

[0039] (1) Stirring: take about 2kg of animal feces and place them in a stirrer, add 10L sterile saline for preliminary processing;

[0040] (2) Filtration: filter the feces slurry through a 2.0mm stainless steel filter to remove large particles, and then filter through a 0.25mm stainless steel filter for 2-3 times to obtain a filtered sample;

[0041] (3) Centrifugation and suspension: centrifuge the filtered sample at a rate of 6000r / min for 15min, and resuspend the precipitate in normal saline to obtain a colorless and odorless fresh fecal liquid;

[0042] (4) Storage: The obtained fresh fecal bacteria liquid can be stored at 80° C. as a frozen fecal bacterial liquid for 1-8 weeks.

[0043] 1.2 Experimental animals and design

[0044] Fecal bacteria donor animals: 1 healthy sow and 1 weaned piglet were selected, without any known infectious diseases, and no antibacterial drugs...

Abstract

The invention belongs to the technical field of animal medicine, and particularly relates to a method for improving growth performance of weaned pigs and reducing the diarrhea rate through coprophilous fungus transplantation. The method for improving growth performance of the weaned pigs and reducing the diarrhea rate through coprophilous fungus transplantation is characterized by including the following steps that firstly, coprophilous fungus liquid is prepared; secondly, the weaned pigs are treated through the coprophilous fungus transplantation method. The method has the advantages that the average daily gain and the average daily feed intake of the weaned pigs are increased, and the diarrhea rate of the weaned pigs can be greatly reduced. The coprophilous fungus liquid of healthy animals is adopted to replace antibiotics, and reference is provided for application of coprophilous fungus transplantation in animal production.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine, in particular to a method for improving the growth performance of weaned piglets and reducing the diarrhea rate by using fecal bacteria transplantation. Background technique [0002] The growth performance of weaned piglets is the most direct index reflecting the nutritional status of weaned piglets. The gastrointestinal tract of weaned piglets is short and small, the development of digestive organs is low, the digestive function is not perfect, and the intestinal microecology is easily unbalanced. In addition, the application of antibiotics has certain damage to the intestinal barrier function of weaned piglets, which affects the healthy growth of pigs. Probiotics can colonize the intestines of animals, regulate the intestinal micro-ecological flora, and maintain the health of the digestive tract. The organic acids and digestive enzymes produced by their metabolic activities can pro...
