Embodiment 1

[0030] Embodiment 1: the preparation of piglet feed additive

[0031]A. Activated slant strains: use LB medium with a pH of 7-7.5 and sterilized at 120°C for 30 minutes to culture Bacillus subtilis CCTCC No.M207086, Lactobacillus acidophilus CGMCC No.10188 and Saccharomyces cerevisiae CCTCC NO: M207178 , cultured at 34°C for 16 hours;

[0032] B. Primary liquid expansion culture: Carry out primary liquid expansion culture for Bacillus subtilis CCTCC No.M207086, Lactobacillus acidophilus CGMCC NO.10188 and Saccharomyces cerevisiae CCTCC NO:M207178 respectively, with an inoculum size of 15%;

[0033] C. Secondary liquid expansion culture: carry out secondary liquid expansion culture on Bacillus subtilis CCTCC No.M207086, Lactobacillus acidophilus CGMCC NO.10188 and Saccharomyces cerevisiae CCTCC NO:M207178 after the first-level liquid expansion culture, the inoculation amount is 15% ;

[0034] D. Preparation of compound micro-ecological preparations: Dried the fermentation bro...

Embodiment 2

[0036] Embodiment 2: Rat safety and disease treatment and disease prevention effect test

[0037] The safety of compound probiotics of the present invention and the effect of treating and preventing diseases are explained below in conjunction with test: compound probiotics of the present invention passes rat acute toxicity test in laboratory of Qingdao Agricultural University, and experimental group is 50 rats, and conventional feed is free Diet, feed the feed additive prepared in Example 1 at the same time, and feed it at 0.6g / 10g body weight for 21 days; the blank control group was 50 rats, which were fed free diet according to the routine, and no feed additive was given.

[0038] The results showed that all the rats in the experimental group survived, moved freely, had smooth hair, normal diet, no secretions in the respiratory tract, eyes and mouth, no symptoms of poisoning, and weight gain. Compared with the blank control group, the body weight of the rats in the experimen...

Embodiment 3

[0039] Example 3: Effect test of feed additives on piglet growth performance, morbidity and diarrhea rate

[0040] 200 sows in labor were randomly divided into experimental group and control group according to the expected farrowing date and parity, with 100 pigs in each group. Add 0.5kg piglet feed additive (prepared in embodiment 1) in the per 1000kg diet of the piglets of the test group, evenly mix in the feed and feed; the sows of the control group and the piglets they produce are fed routinely, and the sows are fed on their own. The experiment started after entering the farrowing room and ended at weaning. The experiment was carried out in the same disease-free pig house. During the experiment, feeding management, immunization and disinfection were carried out according to the conventional methods of the pig farm.

Abstract

The invention provides a novel composite microecological preparation specially for piglets and a preparation method thereof. The preparation is composed of bacterial powder, traditional Chinese medicines and a carrier. The bacterial powder comprises Bacillus subtilis, Lactobacillus acidophilus and Saccharomyces cerevisiae according to a weight ratio of (3-6): (2-3): 1. A large number of experimental results show that the microecological preparation can dynamically regulate the effect of the gastrointestinal flora of the animal. Through bacterial compounding, a feed conversion rate is improved,the growth and development of the animals are promoted, the immunity of the piglets is improved, the antibacterial and anti-viral capability is improved, antibiotics for preventing and treating diseases are replaced and veterinary drug residues are reduced.

Description

technical field [0001] The invention belongs to the field of microecological preparations, and in particular relates to a novel composite microecological preparation for pigs, in particular to a composite microecological preparation for piglets in which composite bacteria are the main ingredient and traditional Chinese medicine is added and the application thereof. Background technique [0002] At the end of the 1940s, when scholars first discovered that antibiotics can promote the growth of livestock and poultry, they began to use subtherapeutic doses of antibiotics as feed additives to promote animal growth or prevent pathogenic bacterial infections and diseases, thus creating a new era. An era of antibiotics as feed additives, which led to a dramatic increase in livestock production. In the process of modern breeding, due to the immature physiological development of suckling piglets, piglet diarrhea is one of the main problems that plague large-scale pig production. Ther...
