Problems solved by technology

However, the extensive use of antibiotics in feed has very serious drawbacks, such as endogenous infections and superinfections caused by antibiotics, the generation of drug-resistant strains, the decline of livestock and poultry immunity, and residues in livestock products and the environment, etc., so many Countries and regions have banned the use of growth-promoting antibiotics at the feeding end

Embodiment 1

[0025] Embodiment 1: The microecological preparation of the present invention is used as a feed additive to treat swine dysentery test

[0026] The test is a single factor test. The test selects 40 diseased piglets within 7 days of age that are naturally infected, typical symptoms, and meet the test requirements in a pig farm. The test pigs were randomly divided into two treatment groups, 20 in each group (half male and half female). Group 1 is the test group: add the microecological preparation of the present invention in the basic ration (concentration of live bacteria is 10 10 CFU / ml) was added at 2 mL / bird; treatment group 2 was the aureomycin control group: 0.1% aureomycin was added to the basic ration. Feed once a day in the morning and once in the evening, and the administration period is 7 days. Piglets had free access to food and water.

Embodiment 2

[0031] Embodiment 2: Probiotics of the present invention are tested on pig breeding after feed fermentation

[0032] The experiment was a single-factor experiment; 120 Duroc×Landrace×Dark York three-way crossbreed pigs with similar body weight were randomly divided into 2 treatment groups, 120 pigs in each group (there was no significant difference in initial body weight among the repeated groups (p >0.05), respectively Breeding in 15 pens, 8 pigs in each pen), treatment group 2 is the control group, the original formula diet in the farm, treatment group 1 is the test group: bacitracin zinc (medium pig feed) and bacitracin were removed from the original formula (Large pig feed), add 4‰ of the prepared bacterial agent dilution to the diet, anaerobically ferment at 25°C for 2 days, and then feed (Table 2). Each group was reared in the same environment, with free access to food and water.

Abstract

The invention belongs to the technical field of composite micro-ecological preparations, and particularly relates to a composite micro-ecological preparation and an application method thereof in livepig breeding. The composite micro-ecological preparation is comprised of the following components in percentage by mass: 20-30% of composite microbial bacterium powder, 1.0-5.0% of isomaltooligosaccharide, 65-80% of rapeseed cake powder and 0.1-0.2% of edible essence. The composite microbial bacterium powder comprises the following five microorganisms: Lactobacillus acidophilus (CICC 6074), Lactobacillus delbrueckii (CICC 6256), Bacillus subtilis (CICC 20872), Candida utilis (CICC 31188), and Saccharomyces cerevisiae (CICC 1854 and CICC 1480). The micro-ecological preparation is used as a feedadditive for piglet breeding. The composite micro-ecological preparation and the using method thereof have the effects of preventing diarrhea and improving the growth performance of piglets.

Description

technical field [0001] The invention belongs to the technical field of compound microecological preparations, and in particular relates to a compound microecological preparation and its application method in pig breeding. Background technique [0002] my country is a large animal husbandry country. According to the data analysis of the Food and Agriculture Organization of the United Nations, half of the world's meat and eggs came from China in the past 20 years. In the process of intensive farming, it is mainly through the method of adding antibiotics to the feed to control and reduce the various stresses of animals due to changes in environmental conditions, such as weaning, sudden changes in weather, etc. This stress response is particularly sensitive and prominent in piglets, and its specific manifestation is piglet yellow and white scour, which is mainly a common enteric infectious disease in piglets during lactation induced by Escherichia coli. Piglet yellow scour ofte...
