Preparation method and application of composite probiotics fermentation Chinese medicinal herb composite feed additive

Abstract

The invention discloses a probiotics fermentation Chinese medicinal herb composite feed additive used for preventing and treating diarrhea of delivery room suckling piglets and weaning conservation piglets. According to laboratory repeated fermentation experiments and actual using effect of products at a plurality of scaled pig farms, a screened and determined formula is as follows: bacillus cereus inoculum size 2-4%, bacillus subtilis inoculum size 2-4%, Chinese medicinal herb inventory 8-20% (main ingredients of which are the root of Chinese pulsatilla, myrobalan, liquorice and schisandra chinensis), and performing liquid state fermentation and then drying. The probiotics fermentation Chinese medicinal herb composite feed additive used for preventing and treating diarrhea of delivery room suckling piglets and weaning conservation piglets can effectively resolve the problem of piglet diarrhea during scaled pig farming process, effectively improve organism immunity and disease resistance capability of piglets, adjust animal enteric micro-ecology balance and repair intestine mucosa damage, and has the effects of improving weaning piglet daily gain by 6%-12% and feed use ratio by 10%-15% and lowering diarrhea rate by 25%-35%. The probiotics fermentation Chinese medicinal herb composite feed additive used for preventing and treating diarrhea of delivery room suckling piglets and weaning conservation piglets is an ideal green environment-friendly safe and novel feed addictive for replacing antibiotic medicines in diarrhea controlling.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation of Chinese herbal medicines, in particular to a compound feed additive produced by a Chinese herbal medicine prescription through a probiotic fermentation method, which has a good control effect on livestock and poultry, especially suckling piglet diarrhea. Background technique [0002] At present, the pig industry has become an important industry related to the national economy and the people's livelihood, and piglet breeding is the key in pig production. Factors such as nutrition, physiology, environment, and pathogenic microorganisms can cause the imbalance of intestinal microbial flora in piglets, leading to dysfunction, indigestion, diarrhea, growth inhibition, and death. According to statistics, the average mortality rate of piglets caused by diarrhea is 12%. Every year, more than 20 million piglets die due to diarrhea, causing direct economic losses of more than 10 billion y...

Problems solved by technology

[0003] At present, for large-scale pig farms, no matter whether the piglets are weaned at 21 days or 28 days, the weaning process will bring a series of stress to piglets (environmental stress, digestive physiological stress, feed stress), and the piglets’ adoption The food intake drops sharply, the intestinal structure changes sharply, the ability to digest and absorb feed decreases, the overall immune level and disease resistance of the body are low, and large-scale diarrhea is prone to occur, which seriously affects the daily weight gain within one week after weaning

At present, the main conventional means of anti-diarrhea and growth-promoting diets at this stage are high copper + high zinc + high antibiotics, especially high zinc is an indispensable anti-diarrhea control method. This kind of weaning diet preparation mode not only causes environmental pollution Great pollution, and prone to growth retardation and pale complexion, long hair and curly hair in the later stage
