Problems solved by technology

For pig sperm, weak acid and slightly higher osmotic pressure are more conducive to its low-temperature storage at 4 °C. Artificially collected semen is prone to microbial contamination, and penicillin and streptomycin are widely used as antibacterial agents in diluents at room temperature. Inhibit the growth and reproduction of microorganisms in preservation diluents, but the two are less effective against Gram-negative bacteria such as Escherichia coli

Embodiment 1

[0020] (1) First of all, beer yeast mud is used as the source of yeast, washed with water for 3 to 5 times, and then centrifuged to obtain a yeast liquid containing yeast cells, and the effective number of viable cells of beer yeast is not less than 1.0×10 6 cfu / ml.

[0021] (2) Broken the yeast cells by the action of microwave radiation. Under the electromagnetic environment with a microwave power of 700W for 4 minutes, grind the grape seeds through a 100-mesh sieve into a fine powder. Organic solvent ethanol, control ethanol concentration 55%, adjust the power of microwave radiation to 300W, act for 45min, belong to the extraction process.

[0022] (3) Add a certain amount of biological flocculant sodium carboxymethyl cellulose to the extract described in (2), control the concentration of the diluent to 15~20g / L, keep it in a constant temperature water bath for 20min, and then perform centrifugation, and take For the supernatant, ethanol is recovered by distillation under r...

Abstract

A method for preparing an antioxidant diluent for low-temperature storage of pig seminal fluid is disclosed. The method includes preparing a yeast cell liquid, crushing yeast cells, adding an organic solvent, performing extraction to obtain a supernatant liquid, concentrating the supernatant liquid, and finally adding an auxiliary material into the concentrate. Yeast is extracted from waste beer's yeast mud and crushed, a yeast extract liquid is adopted as a base solution, and other active components are added to prepare the diluent. The power of microwaves and the concentration of added ethanol are controlled. A certain amount of yeast trehalose is extracted, a certain amount of procyanidin is successfully extracted from added grape powder, and the yeast trehalose and the procyanidin are proved to be good antioxidant compounds in the frozen-semen diluent, and can effectively improve pig seminal fluid storage effects of the diluent.

Description

technical field [0001] The invention belongs to the technical field of breeding industry, and in particular relates to a method for preparing an antioxidant diluent for low-temperature preservation of pig semen. Background technique [0002] Semen preservation is the key to pig artificial insemination technology. It can not only prolong the storage time of sperm, but also facilitate long-distance transportation. Compared with cryopreservation, pig semen cryopreservation technology is convenient and economical in terms of transportation and operation, and the storage time is longer than normal temperature storage, and the cost is lower. At present, research on cryopreservation is still in the stage of screening of diluents. [0003] Cryoprotection is an important factor affecting the quality of pig frozen semen. Since people discovered the cryoprotective properties of glycerol, it has rapidly promoted the development of livestock frozen semen. However, glycerol, as a permeab...
