Embodiment 1

[0039]The microbial feed additive for improving the reproductive performance of sows and its production method, the strains used are all obtained through screening and optimization, and a two-stage fermentation process is adopted at the same time, which includes the following steps:

[0040] 1. First stage fermentation

[0041] The first step. the method that screened Bacillus licheniformis, Lactobacillus plantarum, Lactobacillus casei, Saccharomyces cerevisiae is cultivated in the same expansion medium is optimized;

[0042] Step 2. Transfer the strains into the broth medium respectively, and after culturing at 37°C for 24 hours, select the colonies with obvious colony characteristics, strong vigor and fast growth and reproduction under the microscope to separate them by streaking to save;

[0043] Step 3. Transfer the bacterial strain into an eggplant bottle equipped with nutrient agar as a medium, cultivate it at a temperature of 37°C for 48 hours, and then put it into a r...

Embodiment 2

[0054] 1. In the first stage of fermentation

[0055] Step 4. Inoculate Bacillus licheniformis, Lactobacillus plantarum, Lactobacillus casei, and Saccharomyces cerevisiae in the steam-sterilized medium according to the ratio of 40%, 15%, 10%, and 35%, respectively, and the stirring speed is 220r / min, the culture temperature is 35°C, the ventilation rate is 1:0.6, and the fermentation time is 24 hours, the compound bacterial agent expansion culture solution is obtained;

[0056] Step 5. Inoculate the compound bacterial agent expansion culture solution in the culture medium, the ratio is: strain expansion culture solution 14%, culture medium 12%, sterile water 74%, stir and mix evenly, stirring speed 220r / min, cultivate The temperature is 35 degrees, the ventilation rate is 1:0.6, and the fermentation time is 32 hours;

[0057] Take the fermentation medium according to the following weight ratio:

[0058] Bean cake powder 3%, corn flour 5%, corn steep liquor 0.5%, yeast powde...
