Problems solved by technology

On the one hand, because of the relatively single addition of bacterial agents in previous studies, the improvement of pig production performance is relatively limited, and its clinical application is relatively limited
On the other hand, because the function of microbial agents is a complex system of multi-bacteria cooperation, the detailed mechanism of action has yet to be revealed, which further limits the application of microbial agents in animal husbandry production

Embodiment 1

[0022] 1 Materials and methods

[0023] 1.1 Test material

[0024] 1.1.1 Test animals

[0025] A total of 300 fattening pigs were purchased from a breeding company in Shanghang, Longyan, Fujian, weighing 25±1.6kg.

[0026] 1.1.2 Compound microbial bacteria

[0027] The strains in this example were purchased from Quanzhou Huahui Biotechnology Co., Ltd., a technology company. Cultivated according to existing conventional methods, the composite microbial bacterial agent is a liquid bacterial agent made by fermenting and cultivating the following bacteria, which includes 1.25×10 8 Bacillus subtilis (Bacillus subtilis), Actinomyces israe-lii, Lactobacillus bulgaricus, Saccharomycescerevisiae, Enterococcus faecalis, purple Sulfur bacteria, and add 10g barley to 1L bacterial solution.

[0028] 1.2 Test method

[0029] 1.2.1 Test processing settings

Abstract

The invention belongs to the field of pig feed additives and particularly relates to a complex microbial agent and application thereof. The complex microbial agent is prepared from liquid spawns of the following strains: spore bacteria, actinomycetes, lactic acid bacteria, saccharomycetes, enterococcus and photosynthetic bacteria. The complex microbial fermented agent is used for preparing pig feed additives. The complex microbial agent can increase the lengths of stomachs, colons and ceca of fattening pigs, improve the richness of lactic acid bacteria of stomachs and colons, reduce productionof harmful clostridia major based on clostridium difficile, maintain intestinal structure functions, ensure flora balance and promote production performance, and can be applied to production as a feed additive.

Description

technical field [0001] The invention belongs to the field of pig feed additives, in particular to a compound microbial bacterial agent and its application. Background technique [0002] The abuse of antibiotics in animal husbandry production and the emergence of super drug-resistant bacteria have brought great harm to animal husbandry production and my country's food safety. In order to promote the development of animal husbandry production and ensure food safety, it has become a trend in animal husbandry production to develop safe and efficient compound microbial agents by applying the functional effects of microorganisms. The microbial agent developed according to the microbial function of the pig's gastrointestinal tract is widely used in pig breeding. Many studies have also confirmed that adding microbial agents to feed can significantly reduce diarrhea in suckling piglets, piglets and fattening pigs, while increasing daily weight gain and reducing the ratio of feed to ...
