Problems solved by technology

[0004] The existing delivery methods include no-operation delivery delivery, traditional delivery delivery and common birth powder delivery delivery. The common feature of the three delivery delivery methods is that piglets are easily attacked by pathogenic bacteria after birth, making it difficult for the micro-ecosystem of pigs to balance, resulting in increased neonatal piglet mortality

preparation example Construction

[0059] The present invention also provides the preparation method of the compound bacterial preparation described in the above technical scheme, comprising the following steps:

[0060] first mixing probiotics, prebiotics and yucca extract to obtain a first mixture;

[0061] The first mixture, the montmorillonite and the flavoring agent are mixed for a second time to obtain the composite bacterial preparation.

[0062] Before performing the first mixing, the present invention preferably further comprises separately pulverizing probiotics, prebiotics and yucca extracts to obtain probiotics powder, prebiotics powder and yucca extract powder, respectively. The particle size of the probiotic powder, prebiotic powder and yucca extract powder of the present invention is preferably 200 meshes. In the present invention, an ultrafine pulverizer is preferably used for the pulverization, and the source and model of the ultrafine pulverizer are not particularly limited in the present inv...

Embodiment 1

[0082] Screening conditions for Bacillus subtilis, Bacillus licheniformis, Bacillus natto, and Bacillus pumilus (Bacillus subtilis, Bacillus licheniformis, Bacillus natto, and Bacillus pumilus are all screened according to this method, and will not be repeated):

[0083] Weigh 5g of fresh pig manure and environmental samples, mix the pig manure and environmental samples into a 100mL triangular flask containing sterile saline, shake them evenly, and place them in a constant temperature water bath at 80°C for 15 minutes. minutes, a certain amount of the sample supernatant was added to 100 mL of LB broth medium, and incubated at 37° C., 200 r / min on a shaker for 24 hours.

[0084] Take 1mL of the above shaker culture medium and dilute it to 10 times with sterile normal saline. -1 , 10 -3 , 10 -5 100 μL of each diluted bacterial solution was taken and spread on LB solid medium respectively, and placed in an incubator at 37° C. for 24-36 hours. A single colony on the LB solid me...

Embodiment 2

[0105] A compound bacterial preparation for sow delivery is made up of the following components, and the following components are the bacterial powder of the corresponding bacterial species prepared in Example 1:

[0106] 1 part of Bacillus subtilis powder, 0.5 part of Bacillus natto powder, 0.5 part of Bifidobacterium animalis powder, 0.5 part of soybean oligosaccharide, 0.25 part of isomalto-oligosaccharide, 0.25 part of xylo-oligosaccharide, Yucca extract 0.1 part of material, 800 parts of sodium montmorillonite and 1 part of fragrance.

[0107] Specifically, Bacillus subtilis powder 125g, Bacillus natto powder 62.5g, Bifidobacterium animalis powder 62.5g, soybean oligosaccharide 62.5g, isomalt oligosaccharide 31.25g, xylo-oligosaccharide 31.25g, yucca Extract 12.5g, sodium montmorillonite 100kg and fragrance 125g.

[0108] The components in the same weight unit ratio are used in the following examples, and will not be repeated.

[0109] Preparation method: in an environm...

Abstract

The invention belongs to the technical field of probiotic preparations, and particularly relates to a compound bacterium preparation for sow midwifery and a preparation method and application thereof. The compound bacterium preparation comprises probiotics, prebiotics, montmorillonite, a yucca extract and a flavoring agent, has the effects of improving the intestinal tract and body surface micro-ecological environment of the newborn piglets, drying the body surfaces of the newborn piglets to promote the vitality recovery of the piglets, improving the micro-ecological state of the contact environment of a delivery room and the piglets and preventing and treating related diseases of pigs, and improves the survival rate of the piglets. Meanwhile, the compound bacterium preparation is sprayed into a piglet contact environment, beneficial bacteria can be efficiently inoculated in the environment, an environment in which the beneficial bacteria are dominated is formed, then the micro-ecological delivery effect is consolidated, and the intestinal tract and the body surface of the newborn piglet are promoted to form a more stable micro-ecological state in which the beneficial bacteria are dominated.

Description

technical field [0001] The invention belongs to the technical field of probiotics preparations, and in particular relates to a compound bacterial preparation for sow delivery and a preparation method and application thereof. Background technique [0002] The survival rate of suckling piglets is one of the important determinants of the annual productivity PSY index of sows, and it is also one of the important indicators to measure the level of feeding and management of pig farms. According to reports, at present, the mortality rate of suckling piglets can reach about 40% in the poor free-range households in my country, and the mortality rate of piglets in small and medium-sized pig farms can reach 20% to 25%. Among them, the death caused by pathogenic diarrhea of ​​newborn piglets is an important reason, and the loss to the breeding industry has reached more than one billion yuan, which has become an important factor restricting the development of breeding efficiency.
