Problems solved by technology

[0005] In recent years, the role of bacillus such as Bacillus subtilis, lactic acid bacteria and yeast in animal health care and maintenance of intestinal flora has been paid more and more attention, and it has been found in practice that some bacillus have natural anti-pathogenic effect, but natural spores The anti-pathogenic function of Bacillus is very limited, so it is necessary to provide a Bacillus for broiler digestive system diseases

Embodiment 1

[0069] In a broiler farm in Beijing, spit water frequently occurs in broilers, usually in broilers 20 days old or older, with the highest incidence in 30-day-old broilers. The feathers of sick broilers are scattered and dull, and the crops are enlarged. The autopsy found that there is serious water accumulation, most of the crops are liquid, basically no food, and the glandular stomach is enlarged. A large amount of undigested food accumulates in the glandular stomach. The entire digestive tract muscle And the mucous membrane is loose, inelastic, and easily damaged, and the death rate is also correspondingly increased. Due to water spit, the immune system of broiler chickens is in a sub-healthy state, and the resistance to other pathogenic bacteria and viruses is reduced, resulting in lower resistance to infectious diseases such as Newcastle disease in broiler chickens. In addition, the sick broiler will spit water into the feed trough, causing feed contamination, and then inf...

Embodiment 2

[0073] Infectious diarrhea occurred in a broiler farm in Hebei. The main symptoms of the sick broiler chickens were: the feces of the sick broilers were white or black-green liquid or semi-liquid loose stools, shortness of breath, increased body temperature, loss of appetite, Mental depression, rapid weight loss, and strong infectivity, once a broiler chicken becomes ill, it will spread rapidly in the broiler house, and antibiotic treatment is not obvious, and the epidemic situation cannot be effectively controlled. After analysis, it is recommended to stop using all antibiotics and use GF107 Bacillus subtilis instead. Add 200-300g of feed per ton and use it continuously. After three days, the large area of ​​diarrhea began to alleviate, and the health of broiler flocks improved significantly. Excretion The feces gradually changed from malodorous loose stools to solid normal stools, and the taste was significantly reduced.

[0074] The microorganisms in the feces were extracte...

Embodiment 3

[0076] Example 3: Effect of GF107 Bacillus subtilis instead of antibiotics on broiler weight gain, reduction of feed-to-meat ratio, increase of survival rate and improvement of European index

[0077] A broiler chicken farm in Beijing used GF107 Bacillus subtilis instead of antibiotics. From the start of breeding to the slaughter, the cycle was 40 days. The GF107 Bacillus subtilis was added at a rate of 200g per ton, and continued to be used until the broiler chickens were slaughtered. Among them, broiler chickens The feed contains the following components by weight: corn flour 500-520, wheat bran 30-40, shrimp shell powder 10-15, silkworm chrysalis powder 20-30, bone meal 10-15, wheat flour 30-40, pumpkin powder 30- 40. Celery powder 30-40, hawthorn powder 15-20, fresh Chinese toon 8-10, bamboo shoot 10-15, konjac 20-30, sweet potato 30-40, Niu Dali 2-4, apple seed 10-15 and iodized salt 3 -5.

[0078] Compared with the control group with antibiotics added, the sum of body w...

Abstract

The invention discloses a Bacillus subtilis and its application in bacterial agents and broiler feed, wherein, the preservation number of the Bacillus subtilis in the General Microorganism Center of China Microbiological Culture Collection Management Committee is: CGMCC NO.15940; The date is: June 12, 2018; the classification is named: Bacillus subtilis; the Bacillus subtilis has a stronger function of resisting pathogenic bacteria. The invention also discloses the application of the bacillus subtilis in the preparation of the bacterial agent for treating water vomiting in broilers, and the broiler eating the bacterial agent for treating water vomiting in broilers can well relieve and prevent the water vomiting in broilers. The invention also discloses the application of the bacillus subtilis in preparing the bacterial agent for treating broiler diarrhea, and the broiler eating the bacterial agent for treating broiler diarrhea can well alleviate and prevent broiler diarrhea. The invention also discloses a feed for broilers, which can accelerate the weight gain of broilers, reduce the feed-to-meat ratio to a certain extent, and save production costs.

Description

technical field [0001] The invention relates to the technical field of microbes, in particular to a bacillus subtilis and its application in bacterial agents and broiler feed. Background technique [0002] The aquaculture industry is an important agricultural pillar industry that is related to the national economy and the people's livelihood. However, various infectious diseases have become a huge hazard to the modern aquaculture industry, and antibiotics enable the farm to limit the animal's breeding space and activities while keeping the animals in optimal health. As a result, the modern farming system has gradually fallen into the predicament of dependence and abuse of antibiotics, and animal husbandry once consumed half of the world's antibiotic consumption. [0003] Among them, the broiler industry is an important part of the animal husbandry industry, providing a large amount of eggs and meat for the people. In broiler and layer broiler farming, digestive system disea...
