Abstract

The invention relates to a preparation method of a frozen pig semen diluent. The frozen semen diluent comprises four diluent components: a diluent A comprises glucose, sodium citrate, sodium chloride and penicillin; a diluent B comprises lactose, glucose, penicillin, streptomycin and fresh yolk; a diluent C comprises glucose, sodium citrate, sodium chloride, penicillin, glycerol, coconut oil monoethanol amide, lauryl sodium sulfate, triethanolamine, hydrochloric acid and distilled water; a diluent D comprises anhydrous citric acid, caffeine g, trihydroxymethyl amino methane, sodium bicarbonate, ethylenediamine tetraacetic acid disodium salt, sodium pyruvate and glucose; the preparation steps are as follows: respectively dissolving raw materials in 100ml of double distilled water to prepare four diluents, regulating the pH values to be 6.5-7.5, and refrigerating in a refrigerator. The product disclosed by the invention is used for the freezing storage of the pig semen diluent.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a preparation method of pig frozen semen dilution. Background technique [0002] Today, with the rapid development of biotechnology, the semen of some excellent male animals is processed into frozen semen through related technologies, and the use of artificial insemination technology is vigorously promoted. Among them, the combination of pig frozen semen and artificial insemination technology has a very broad market prospect in the modern breeding industry, and it is not limited by the death of the boar, semen collection interval, and reproductive sterility; it is not limited by time and geographical differences. And it can greatly reduce the number of male animals, reduce the cost of feeding, maximize the genetic probability of high-quality genes, and bring huge economic benefits to the breeding industry. From a health point of view, frozen semen provides enough time for disease de...
