Abstract

The invention discloses an application of a polysaccharide substance in preparation of a dilution solution for freeze preservation of goat sperms and a preparation method of the dilution solution. Thepolysaccharide substance comprises one or more selected from the group consisting of tremella polysaccharide, lentinan, auricularia polysaccharide and cordyceps polysaccharide. The invention also provides the dilution solution for freeze preservation of the goat sperms. The dilution solution comprises the polysaccharide substance, a nutrient substance, a buffer substance and the like. The dilution solution for freeze preservation of the goat sperms provided by the invention has the effects of improving a sperm motility rate, an acrosome and plasma membrane integrity rate after freeze preservation, and significantly improving goat reproductive performance and economic benefits.

Description

technical field [0001] The invention belongs to the field of animal biotechnology and relates to animal reproduction technology, in particular to the application and preparation method of polysaccharides used to prepare diluents for goat semen preservation. Background technique [0002] Animal semen cryopreservation is the special treatment of semen, stored at ultra-low temperature, in order to achieve the purpose of long-term preservation. However, in the process of cooling and cryopreservation, sperm are prone to various damages, including physical, chemical and biological damage. Compared with fresh semen, the sperm survival rate, sperm viability rate, acrosome integrity rate, mitochondrial activity and conception rate of the frozen-thawed semen were significantly reduced, especially for goat semen, which is of great importance to production practice and It is an extremely unfavorable factor for scientific research. Although the cryopreservation technology of goat semen...
