Embodiment 1

[0042] 1. Fermentation liquid

[0043] (1) Cordyceps gunis strain: Acremonium terricola MKL18 (can be purchased from Hefei Miikeluo Biological Engineering Co., Ltd.);

[0044] (2) Seed cultivation:

[0045] The medium for seed culture is: 600g white granulated sugar, 300g silkworm chrysalis powder, 150g peptone, 200g soybean powder, 100g yeast powder, 10g MgSO 4 , 10g KH 2 PO 4 , dissolved in 20L water, natural pH; sterilized by high pressure steam at 121°C for 30min.

[0046] The conditions of seed fermentation are as follows: temperature is 25°C, ventilation rate is 1.00L / (L·min), inoculum size is 5% (mass fraction), liquid volume in 30L airlift fermentation tank is 67%, and fermentation time is 24h.

[0047] (3) Expansion of training:

[0048] The culture medium for expanded cultivation is: 6000g white granulated sugar, 3000g silkworm chrysalis powder, 1500g peptone, 2000g soybean powder, 1000g yeast powder, 100g MgSO 4 , 100g KH 2 PO 4 , dissolved in 200L water, na...

Embodiment 2

[0062] In this embodiment, Acremonium terricola (Acremonium terricola) MKL18 is used as the fermentation object for fermentation to obtain fermentation broth, fermentation powder and solid culture; except that the medium used for liquid fermentation is different from that of Example 1, the remaining contents are the same as those in Example 1. Example 1 is the same.

[0063] The medium for seed culture is: 600g white granulated sugar, 550g yeast powder, 200g soybean powder, 10g MgSO 4 , 10gKH 2 PO 4 , dissolved in 20L water, natural pH; sterilized by high pressure steam at 121°C for 30min.

[0064] The culture medium for expansion is: 6000g white granulated sugar, 5500g yeast powder, 2000g soybean powder, 100g MgSO 4 , 100g KH 2 PO 4 , dissolved in 200L water, natural pH; sterilized by high pressure steam at 121℃ for 30min.

[0065] The components in the fermentation broth, fermentation powder and solid culture prepared in this example were determined, and the results ar...

Embodiment 3

[0069] In this embodiment, Acremonium terricola (Acremonium terricola) MKL18 is used as the fermentation object for fermentation to obtain fermentation broth, fermentation powder and solid culture; except that the medium used for liquid fermentation is different from that of Example 1, the remaining contents are the same as those in Example 1. Example 1 is the same.

[0070] The medium for seed culture is: 600g white granulated sugar, 400g yeast powder, 200g soybean powder, 150g peptone, 10gMgSO 4 , 10g KH 2 PO 4 , dissolved in 20L water, natural pH; sterilized by high pressure steam at 121°C for 30min.

[0071] The culture medium for expansion is: 6000g white granulated sugar, 4000g yeast powder, 2000g soybean powder, 1500g peptone, 100g MgSO 4 , 100g KH 2 PO 4 , dissolved in 200L water, natural pH; sterilized by high pressure steam at 121℃ for 30min.

[0072] The components in the fermentation broth, fermentation powder and solid culture prepared in this example were d...

Abstract

The invention discloses application of cordyceps strain ferments as a feed additive in improvement of the reproductive performance of boars. When the boars are fed with the cordyceps strain ferments,the semen volume, sperm motility, sperm density and libido status of the boars can be significantly increased, the sperm deformity rate is reduced, and the levels of follicle-stimulating hormone, luteinizing hormone and testosterone hormone are increased, so that the reproductive performance of the boars is improved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding, in particular to the application of a fermented product of Cordyceps fungi as a feed additive in improving the reproductive performance of boars. Background technique [0002] In large-scale and intensive modern pig production, artificial insemination technology has been rapidly promoted and applied in order to reduce the amount of boars raised, reduce the spread of reproductive diseases during the mating process, and improve the production efficiency of boars. Although the proportion of breeding boars in the herd is getting smaller and smaller, their role in the pig farm is becoming more and more important. The pig farming industry adopts the method of artificial insemination, and maximizes the selection of breeding pigs with good genes and high fecundity for breeding and breeding, thereby optimizing the quality of the pig herd, improving the production performance of the ...
