Embodiment 1

[0037] The preparation method of the microbial feed additive for improving the reproductive performance of boars adopts strains obtained through screening and optimization, and adopts a process of combining pure breed fermentation and compound fermentation at the same time, which includes the following steps:

[0038] Step 1: Transfer the strains into the broth medium respectively, and after culturing at 35°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 be preserved;

[0039] The second step: Lactobacillus lactis is inoculated in the liquid medium, and the liquid medium is composed of: soybean meal 3%, glucose 1%, yeast extract 1%, magnesium sulfate heptahydrate 0.05%, potassium dihydrogen phosphate 0.03%, water 94.92%, the pH is adjusted to 5.0, the culture temperature is 30°C, and the time is 20h, to obtain the culture of Lactobacillus lactis;

Embodiment 2

[0045] Step 1: Transfer the strains into the broth medium respectively, and after culturing at 35°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 be preserved;

[0046] The second step: Lactobacillus lactis is inoculated in the liquid medium, and the liquid medium is composed of: soybean meal 4%, corn steep liquor 2%, glucose 1.2%, yeast extract 1.2%, magnesium sulfate heptahydrate 0.03%, dihydrogen phosphate Potassium 0.06%, water 91.5%, pH adjusted to 5.0, culture temperature 35°C, time 24 hours, to obtain Lactobacillus lactis culture;

[0047] The third step: Bacillus subtilis is inoculated in the solid medium, and the solid medium is composed of: bran 74%, rice husk 12%, corn flour 6%, soybean meal 7.94%, magnesium sulfate 0.05%, manganese sulfate 0.01%, The pH is adjusted to 6.4, the culture temperature is 39° C., and the time is 38 hours to obtain a ...

Abstract

The invention involves a microbial feed additive and its prepare methods which improveboar fecundity, it is characterized by:lactic acid lactobacillus and bacillus subtilis which are optimized make the products rich in beneficial microbios and variety of active metabolite through the means of combining pedigree breed fermentation and composite fermentation. The advantages of the invention are maintaining boar body health,repairing tissue injury, improving the fecundity and the body immune function, thus making the boar maintain strong sexuality and produce high grade semen, extending boar life, and nontoxic, nonpersistent and the use is convenience.

Description

technical field [0001] The invention relates to a microbial feed additive for improving the reproductive performance of boars and a preparation method thereof, belonging to the technical field of feed additives. Background technique [0002] The quality of boars produced, especially the quality of semen directly affects the reproductive performance of sows. At present, there are factors such as overuse, irrational nutrition, disease problems, and environmental pollution in breeding, which directly affect the quality of boar semen, resulting in breeding The conception rate is low, and the economic benefits are not significantly improved. Due to the long-term breeding of boars in pens, the lack of playgrounds outside the pens, and the high frequency of use, a considerable part of boars have premature aging, weakness in climbing, slow sexual reflexes during mating, decline in semen quality and quantity, and decline in breeding conception rate, etc. Seriously affected the produ...
