Embodiment 1

[0020] Inoculate Lactobacillus plantarum, Lactobacillus bulgaricus, Bacillus subtilis, Bacillus licheniformis, Bifidobacterium, Enterococcus faecalis and yeast into their respective appropriate medium, culture at 37.5°C for 36 hours, take 150mL of seed culture and inoculate The fermenter continued to expand and cultivate until the concentration of viable bacteria reached 3×10 8 When CFU / mL, stop the culture. The fermentation broth was centrifuged at 4500rpm for 20min at 8°C, and the cells in the lower layer were collected and mixed by equal weight. Take 150 parts of the cell mixture, 100 parts of sodium alginate, 50 parts of attapulgite and 50 parts of dextrin, and stir at 100 rpm for 10 minutes at 8°C to fully absorb the cells. Spray 250 parts of 7% skim milk into the mixture, stir at 100 rpm at 8°C for 10 minutes, and then dry at low temperature for 3 hours at 8°C, then pulverize to 100 mesh. Take 600 parts of mixed probiotic preparations, 200 parts of manno-oligosaccharid...

Embodiment 2

[0022] Inoculate Lactobacillus salivarius, Lactobacillus bulgaricus, Bacillus subtilis, Bacillus laniciformis, Bifidobacterium, Enterococcus faecalis and yeast into their respective appropriate medium, culture at 37.5°C for 36h, take 150mL of seed culture to inoculate into the fermenter to continue to expand the culture until the concentration of viable bacteria reached 3 × 10 8 When CFU / mL, stop the culture. The fermentation broth was centrifuged at 4500rpm for 20min at 8°C, and the cells in the lower layer were collected and mixed by equal weight. Take 150 parts of the cell mixture, 100 parts of sodium alginate, 50 parts of zeolite powder and 50 parts of dextrin, and stir at 100 rpm for 10 minutes at 8°C to fully absorb the cells. Spray 250 parts of 7% skim milk into the mixture, stir at 100 rpm at 8°C for 10 minutes, and then dry at low temperature for 3 hours at 8°C, then pulverize to 100 mesh. Take 600 parts of mixed probiotic preparations, 200 parts of lactose oligosac...

Embodiment 3

[0024] Inoculate Lactobacillus plantarum, Lactobacillus bulgaricus, Bacillus subtilis, Bacillus laniciformis, Bacillus licheniformis, Bifidobacterium, Enterococcus faecalis and yeast into their respective appropriate medium, culture at 37.5°C for 36 hours, and take the seeds 150mL of the culture was inserted into the fermenter to continue to expand the culture until the concentration of viable bacteria reached 3×10 8 When CFU / mL, stop the culture. The fermentation broth was centrifuged at 4500rpm for 20min at 8°C, and the cells in the lower layer were collected and mixed by equal weight.

Abstract

The present invention discloses a synbiotic oral spray preparation for hatched young meat chickens. The synbiotic oral spray preparation comprises the following components in mass ratios: the ratios of probiotics: an adsorption carrier: a protective agent: prebiotics are (1-3):(1-3):(2-3):(3-5). The synbiotics (probiotics + prebiotics) given by the oral artificial spraying overcome problems that the hatched young meat chickens are based on yolk sac nutrition in an early period and little in feed intake, and cannot provide and meet healthy development of intestinal tracts by means of feed addition. The synbiotic oral spray preparation is simple in preparation method, and safe and effective to use, fully exerts the early period growth potential of the newborn young meat chickens, is beneficial to the healthy intestinal development of the young meat chickens in the early period, improves digestibility of nutrients, enhances immune functions, ensures a good performance in the whole growthperiod, and is also conducive to improving a later production performance.

Description

technical field [0001] The invention relates to a synbiotic oral spray preparation for hatching broilers and a preparation method thereof, belonging to the technical field of poultry additives. Background technique [0002] At present, in the process of large-scale broiler farming in China, environmental pollution is serious, disease infection and prevention and control are under great pressure, and the problem of indiscriminate use and abuse of antibiotics is extremely prominent. Therefore, the problem of drug residues in broilers has increasingly attracted the attention of consumers, and the country has also begun to pay attention to the problem of food safety with antibiotics, and vigorously promote the new model of broiler chicken replacement and antibiotic-free breeding. Among them, the abuse of antibiotics destroys the physical barrier and immunity of intestinal broilers, and at the same time causes the increase of intestinal microbial resistance and the imbalance of p...
