Abstract
The invention belongs to the field of biotechnology and relates to preparation of animal sperm low-temperature and freeze preservation diluents, in particular to a horse sperm low-temperature and freeze preservation liquid. The sperm low-temperature and freeze preservation diluent is prepared by combining sodium bicarbonate, hydroxyethylpiperazine ethane sulfonic acid, trisodium citrate dihydrate, potassium citrate monohydrate, sodium hydroxide, lactose, glucose, inositol, gentamicin, neomycin, apramycin, colistin, amphotericin, sodium pyrophosphate, sodium caseinate, whey protein, an antioxidant and deionized water. The horse sperm low-temperature and freeze preservation diluent can effectively increase the survival rate of sperms obtained after unfreezing of low-temperature and freezing of horse seminal fluid and the hybridization conception rate. Compared with a conventional method, the method is easy and stable to implement and especially remarkable in technical effect.
Description
technical field [0001] The invention belongs to the field of biotechnology and relates to the production of animal semen low temperature and cryopreservation liquid, in particular to a low temperature and cryopreservation diluent for horse sperm. Background technique [0002] my country is a big country in the horse industry, and the number of horses ranks second in the world. As a major large animal, horses used to be closely related to human production and life. After the rise of the machinery industry, the service value of horses weakened and gradually faded out of people's lives. In recent years, with the improvement of people's living standards in our country, the modern horse industry, which mainly focuses on products and cultural leisure, has quietly emerged in my country. The development of the modern horse industry urgently requires the use of artificial insemination to improve horses. Low temperature and cryopreservation) are the core technologies in the process of...
