Abstract

The invention discloses a compound probiotic agent for improving immunity of dogs and reducing incidence of diarrhea as well as a preparation method and application thereof, and belongs to the field of the compound probiotic agent. The compound probiotic agent is prepared by mixing and compounding a lactobacillus plantarum KT-Lp9 microbial agent, a lactobacillus casei zhang microbial agent, a lactobacillus plantarum P-8 microbial agent, a bifidobacterium animalis subsp. lactis V9 microbial agent and a dilution carrier, wherein the quantity of viable bacteria of the four kinds of microbial agents is more than or equal to 2*10<11>CFU / g. The compound probiotic agent with different contents of viable bacteria only can be applied to 96 dogs at different ages for 60 days, so that the immunity of the test dogs can be improved, and the incidence of diarrhea and the sickness degree are reduced. Main representations are that the feed intake and growth rate of the dogs are increased, leukocyte counts, lymphocytes counts and neutrophil counts in blood are controlled, and the contents of four immunologic factors including immune globulin G, interleukin 6, interferon alpha and tumor necrosis factor alpha in the blood can be increased; and meanwhile, the content of secretory immunoglobulin A (SigA) in excrement is increased.

Description

technical field [0001] The invention belongs to the field of compound probiotic agents, and in particular relates to a compound probiotic agent for improving the immunity of pet dogs and its preparation and application. Background technique [0002] Diarrhea in dogs is a common clinical disease in dogs. It has many and complicated causes and is difficult to diagnose and treat. Poor, lack of energy, weak constitution. At present, the prevention and treatment of canine diarrhea mainly rely on antibiotics and chemical drugs. Such methods are low-cost and quick-acting in clinical practice, but long-term use will inevitably bring serious threats to public safety, including the increasing number and types of drug-resistant strains , or even bacterial mutation or horizontal transfer of drug-resistant genes, destroying the intestinal micro-ecological system of the body, making the body more sensitive to new pathogens, thus making the treatment of diarrheal diseases more difficult a...
