Embodiment 1

[0077] Embodiment 1, the preparation of composite bacterial agent for broilers

[0078] This example relates to two kinds of composite bacterial agents for broilers, which are composite bacterial agents A for broilers and composite bacterial agents B for broilers.

[0079] Composite microbial agent A for broilers is to dilute the liquid strains of Bacillus subtilis RJGP16, Saccharomyces cerevisiae CICC1562 and Lactobacillus plantarum CICC22696 to 10 8 After cfu / ml, the mixture was mixed according to the colony-forming unit number ratio of 1:3:1.

[0080] The compound bacterial agent B for broilers is to dilute the liquid strains of Bacillus subtilis RJGP16, Saccharomyces cerevisiae CICC1562 and Lactobacillus plantarum CICC22696 to 10% respectively with sterile water. 8 After cfu / m1, the mixture was mixed according to the colony-forming unit number ratio of 1:1:1.

[0081] Wherein, the liquid strain of Bacillus subtilis RJGP16 is a culture obtained by culturing with fermentat...

Embodiment 2

[0085] Embodiment 2, the preparation of broiler probiotics

[0086]This example provides two kinds of probiotics for broiler chickens, respectively called probiotics A for broilers and probiotics B for broilers.

[0087] The probiotics A for broilers is a culture obtained by using the fermentation medium A of Example 1 to cultivate the composite microbial agent A for broilers of Example 1. The specific preparation method is as follows: the broiler composite bacterial agent A of embodiment 1 is inserted into the 200L embodiment according to the inoculum amount (the volume of the composite bacterial agent inserted and the volume ratio of the fermentation medium) of 6% (volume ratio). In a 500L fermenter of fermentation medium A of 1, cultivate for 42 hours at 34°C, with an aeration rate of 600L / h and a stirring speed of 150rpm, collect all the cultured substances (fermentation liquid) in the fermenter, and add The rice husk powder was dried at 50° C. to obtain the probiotic pre...

Embodiment 3

[0089] Embodiment 3, improve broiler body weight with the broiler chicken probiotic A of embodiment 2

[0090] 1.1 Test animals

[0091] Select 12,000 1-day-old healthy chicks of Arboriga—Quick large white-feathered broiler chicken with a body weight of 50±5 grams, and divide them into 4 treatment groups at random, namely, the control group, the 0.015% probiotics group, and the 0.025% probiotics group. Ecological preparation group and 0.05% probiotic preparation group. There were 3 replicates per treatment group with 1000 chickens per replicate.

[0092] 1.2 Diet

[0093] Broiler brooding period diets were divided into broiler brooding period common rations, 0.015% broiler probiotics A brooding rations, 0.025% broiler probiotics A brooding rations, 0.05% broiler probiotics A brooding rations. Among them, the common diet for broiler brooding period is shown in Table 1; 0.015% broiler chicken probiotics A brooding period diet is added to the common diet for broiler chicken br...

Abstract

The invention discloses a complex microbial inoculant for broiler chickens and an application thereof to improvement of broiler chicken productivity and immunity. Active ingredients of the complex microbial inoculant for the broiler chickens include bacillus subtilis, saccharomyces cerevisiae and lactobacillus plantarum. By means of feeding the broiler chickens with broiler chicken ration prepared from probiotics containing the complex microbial inoculant, contents of valine, methionine, phenylalanine, cystine, tyrosine, proline and crude protein of chicken can be increased remarkably, breast muscle tenderness, breast muscle tonicity and chicken leg muscle chewiness of the chicken can be improved remarkably, and holesterol content, fat content, drip loss and the like of the chicken are lowered; productivity such as slaughtering rate, meet-to-feed ratio, apparent digestibility of protein, calcium and phosphorus, and weight of the broiler chickens can be increased significantly; thymus index, spleen index, bursal index, red blood cell-C3b receptor rosette rate, red blood cell immune complex rosette rate, protein content in serum, alpha-amylase content and cholinesterase content of the broiler chickens can be increased significantly.

Description

technical field [0001] The invention relates to a composite microbial agent for broiler chickens and its application in improving the production performance and immune performance of broiler chickens. Background technique [0002] During the long-term evolution of broilers, the microorganisms in the digestive tract and the host have formed a stable symbiotic relationship, which can maintain the micro-ecological balance in broilers, and has the functions of promoting the development of digestive organs, resisting the invasion of pathogenic microorganisms, and buffering the sudden impact of unfavorable factors. It is beneficial to maintain good health level and production performance of broilers. In recent years, the scale of broiler farming has gradually expanded. Although the scale of industrialized farming has brought greater economic benefits to farmers, the adverse factors such as the deterioration of the breeding environment, the abuse of antibiotics and other preventive...
