Problems solved by technology

With the extension of storage time, the motility of semen decreases, the integrity of the plasma membrane of sperm is destroyed, and the survival time of sperm in the reproductive tract of ewes is also shortened, which leads to the increase of embryo mortality and the decrease of conception rate

Abstract

The invention discloses a preservation method of animal fresh semen and fresh semen preserving diluent specially used by the preservation method. The preservation method of the animal fresh semen, which is provided by the invention, comprises the following step of preserving the animal fresh semen by adopting the fresh semen preserving diluent; the fresh semen preserving diluent is prepared from 38 to 47mg / mL Tris, 510 to 640 units / mL penicillin, 580 to 710 units / mL streptomycin, 26 to 38mg / mL citric acid, 9 to 11mg / mL glucose, 0.35 to 0.42mg / mL vitamin B12 and 0.09 to 0.11mL / mL glycerinum. Experiments prove that by the method provided by the invention, the fresh semen of a breeding ram can be preserved for 24 to 96h, then insemination is performed on ewes, the conception rate of the ewes is between 83.5% and 86.2%, and the conception rate is not significantly different from the natural mating conception rate of the ewes. Therefore, by adopting the method provided the invention, the animal fresh semen can be preserved, and the preservation method has important application value.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for preserving animal fresh essence and a special fresh essence preservation diluent thereof. Background technique [0002] Artificial insemination is a powerful means for efficient multiplication of fine sheep populations, and the quality of semen determines the success or failure of artificial insemination techniques. At present, most sheep farms in China use low-temperature storage to store fresh sheep essence for a short period of time, and the effective storage time of fresh essence is only 1-2 days. With the prolongation of storage time, the motility of semen decreases, the integrity of sperm plasma membrane is destroyed, and the survival time of sperm in the reproductive tract of ewes is also shortened, which leads to the increase of embryo mortality and the decrease of conception rate. Therefore, how to effectively preserve sheep's fresh essence plays an important r...
