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...

Abstract

The invention discloses an application of Cordyceps bacterial strain fermentation products to a feed additive for improving breeding performance of cocks. The Cordyceps bacterial strain fermentation products are used for feeding cocks in order to substantially improve seminal fluid amount, sperm vitality and sperm density of cocks, reduce abnormal rate of sperms, promote cocks to secrete follitropin, lutropin, testosterone and other hormones, so that cock breeding performance 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 roosters. Background technique [0002] With the continuous improvement of people's living standards, people's demand for livestock and poultry products is also increasing. The intensification of poultry breeding and large-scale high-efficiency breeding are also developing rapidly, and artificial insemination technology has been widely used in animal husbandry production. Therefore, the requirements for the reproductive performance of male livestock and poultry are also getting higher and higher. [0003] In large-scale breeding chicken production, the quality of the semen of the rooster directly affects the reproductive performance of the hen. At present, the reduction in the reproductive performance of roosters in my country has resul...
