In recent years, the livestock industry in China has been greatly developed, but with the development of the livestock breeding industry and the improvement of the intensification degree of the livestock breeding industry, various problems are caused by the overuse of antibiotics, the breeding environment is worsened, the variation rate of pathogens is improved, symptoms are atypical, old diseases are new, new diseases are frequent, and the control is more and more difficult.
Common diseases of poultry comprise escherichia coli, enteritis, salpingitis and the like, but the current common solution is to use antibiotics, the phenomenon of unreasonable use of antibiotics also occurs frequently, the antibiotics play a role and play a role in screening drug-resistant bacteria, according to the data detected by a bacterial drug-resistant detection network in China, staphylococcus has over 50 percent of drug resistance to various common antibiotics such as methicillin, macrolides, quinolones and the like in over 100 domestic bacteria, and the drug resistance of escherichia coli to antibiotic drugs is over 50 percent.
At present, the nation has strict rules on the use of antibiotics, and aims to prevent feed from resisting, limit cultivation and prevent food from resisting. In 2018, the work scheme of animal antibacterial use reduction action trial point issued by rural agricultural departments (2018-2021) defines the time schedule of feed-end resistance reduction and resistance limitation, and the feed resistance is imminent.
Importance of the intestinal microecological balance of poultry: the intestinal tract is not only the main site for the digestion and absorption of nutrients in the body, but also the congenital barrier for the body to resist external pathogenic microorganisms and their harmful metabolites. The intestinal barrier consists of a microbial barrier, a chemical barrier, a physical barrier and an immune barrier in sequence from the basal side of the intestinal lumen, and different barriers have different biological functions and molecular regulation mechanisms.
The intestinal tract of healthy animals has a large amount of bacteria to form a microecosystem of the intestinal tract of the animals, the normal intestinal tract function is the guarantee of the health of animal organisms and is the key for improving the growth performance of poultry, and the intestinal barrier of the poultry is damaged, so that the health of the animals is influenced by different degrees. The probiotics can inhibit the growth and adhesion of pathogenic bacteria in the intestinal tract by means of colonizing and resisting, dominating population action, generating bacteriostatic metabolites, promoting body immunity and the like, and establish the dominant position of the probiotics, thereby maintaining the microecological balance in the intestinal tract. The survival rate of viable count in animal bodies of the existing microecological preparation is poor, so that the effect of regulating intestinal tracts is poor.

As can be seen from the data of the SD-3301 probiotics on the antibody level of the broiler chicken in the table 6, after the microecological product is used, the antibody levels of ND and H9 are obviously improved compared with the control group, which indicates that the SD-3301 probiotics can stimulate the mucosal immunity function and improve the nonspecific immunity, and in addition, the SD-3301 probiotics generate a large amount of acidic substances such as lactic acid and acetic acid in the digestive tract, so that the pH value at the rear end of the digestive tract is effectively reduced, the growth and the propagation of pathogenic bacteria such as escherichia coli and salmonella are inhibited, the vertical transmission of salmonella is prevented, and the occurrence of enteritis is reduced.
TABLE 7 influence of SD-3301 on the level of immunity
Figure BDA0002802088360000091
As can be seen from Table 7, the antibodies in the experimental group are all higher than those in the control group, the differences are all obvious (p is less than 0.05), the use before and after immunization can obviously improve the immune response, improve the vaccine titer, and accelerate the generation and maintenance of the antibodies, and the probiotic bacteria components act on immune organs in the form of immune adjuvants to promote the immune response of the organism, and the organism is in a high-level immune response state after young birds feed SD-3301 probiotics.
5. Experiment for improving feces
The diarrhea incidence of the experimental group is reduced by 94% compared with the control group, the diarrhea and overfeeding conditions are obviously reduced, the feed utilization rate is improved, and the digestion and absorption are promoted, as shown in figures 9-10.
6. Average weight gain
From FIG. 11, the weight of the experimental group was 5.57 jin, and the weight of the control group was 5.25 jin. The SD-3301 product can improve the weight gain of chicken and improve the production performance.
7. Meat ratio of materials
From FIG. 12, it can be seen that the average feed-meat ratio of the SD-3301 experimental group is reduced by 0.02 compared with the control group; the SD-3301 product is shown to be capable of regulating intestinal tracts of broiler chickens, promoting nutrient absorption and improving the utilization rate of feed.
8. Increase survival rate
As can be seen from FIG. 13, the survival rate of the broiler chickens in the SD-3301 experimental group is 1.96% higher than that of the broiler chickens in the control group, which indicates that the product can significantly improve the physique of the broiler chickens, improve the health conditions of the broiler chickens and reduce the morbidity of the broiler chickens.
9. Weight of chicken
TABLE 8 hairy Chicken weight
Experiment grouping Hairy chicken weight (kilogram)
Control group 87363
Experimental group 90658
As shown in Table 8, the total weight of the experimental group was 3295kg higher than that of the control group. The SD-3301 product is shown to be capable of increasing the weight of chickens, the weight of the chickens reflects the growth performance of chicken flocks, and the larger the weight is, the better the growth performance of the chickens is, and the higher the income is.
10. Input-output ratio
TABLE 9 use of the difference in input-output ratio between the SD-3301 experimental group and the control group
Figure BDA0002802088360000092
Figure BDA0002802088360000101
The data in the table 9 show that the income of the SD-3301 product is increased by 7.8% with the control group under the same investment cost, which shows that the SD-3301 product can significantly increase the slaughter weight of the broiler chickens, reduce the feed-meat ratio, increase the survival rate of the broiler chickens and bring higher economic benefit for farmers.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
