USE OF BACILLUS COAGULANS STRAIN IN INCREASING EGG
PRODUCTION IN LAYING HEN
FIELD OF THE INVENTION
[0001] The present invention relates to the field of microbial technology, in particular to a use of a Bacillus coagulans strain in increasing egg production at a later laying period in a laying hen.
BACKGROUND
[0002] With the improvement of living standards, people are becoming increasingly concerned with food safety and healthy life problems caused by antibiotics and chemical residues, and there is an increasing demand for green poultry products without drug residues. The microbial ecological agent plays a regulating role by promoting the growth and proliferation of normal microbial floras and inhibiting the growth and proliferation of pathogenic bacteria. Due to its prominent prevention and health care effects, the microbial ecological agent can replace antibiotics and chemicals in livestock breeding and achieve true “green and pollution-free”.
[0003] Eggs have already become a necessity in people’s daily life. The use of the microbial ecological agent in laying hen breeding can improve health status of laying hens and egg production. CN 103518980B reports a microbial ecological agent obtained by mixing Lactobacillus plantarum and Bacillus subtilis, and body health level can be improved after use. CN 101715879B reports a feed additive prepared from an enzyme preparation and Enterococcus faecium, which can improve health status of chickens and egg production level. CN 103202400B reports a microbial ecological agent mixed by Lactobacillus casei, Lactobacillus plantarum and Bacillus licheniformis, which can improve the egg laying performance of broiler chickens and egg breed chickens. These reports prove that the microbial ecological agent has bright prospects in green cultivation.
[0004] Generally speaking, low-yield individuals in a chicken flock are eliminated after 300 days from egg laying, egg production after 500 days from egg laying reduces significantly, and the chicken flock is regenerated if necessary. However, there are few researches on how to improve the egg laying performance of laying hens at a later laying period and utilize feed to the maximum extent.
SUMMARY
[0005] In view of the above problems in the prior art, the applicant provides a use of a Bacillus coagulans strain in increasing egg production in a laying hen. By adopting the present invention in laying hen breeding, the egg laying performance of laying hens at a later laying period can be improved significantly, that is, the egg production and the egg laying rate are improved while the feed-egg ratio is reduced.
[0006] Technical solutions of the present invention are as follows: [0007] A use of a Bacillus coagulans strain in increasing egg production in a laying hen, the Bacillus coagulans is combined with a Bacillus subtilis (CCTCC No. M 2011443) and a Bacillus licheniformis (CCTCC No. M 2012458) to prepare a microbial ecological combined agent capable of increasing egg production in a laying hen; and the usage amounts of the above three bacterial species are respectively as follows: [0008] viable count of bacterial species per bacterial species gram of the microbial ecological combined agent
Bacillus coagulans 0.4x 108-2.0X 1010 cfu

The genus of the bacterial species is effectively and accurately determined through such means for the strain as morphological observation, physiological & biochemical experiments, and 16S rDNA analysis.
[0014] Finally, a strain with a serial number of ZS-007 is obtained, and identified as a Bacillus coagulans.
