Problems solved by technology

So far, the sperm motility, acrosome integrity rate, and plasma membrane integrity rate of pig sperm after freezing are not ideal, resulting in the conception rate and litter rate of sows artificially inseminated with frozen semen in commercial pig production. It is relatively low and cannot be widely used, which seriously reduces the utilization rate of high-quality boars, the cost of feeding cannot be reduced, and the pollution of the ecological environment has not been alleviated.

Abstract

The invention relates to a preparation method of pig frozen semen dilution. Including 4 diluent components and the preparation steps are as follows: Liquid A: glucose, sodium citrate, sodium chloride, penicillin; Liquid B: lactose, glucose, penicillin, streptomycin, fresh egg yolk; Liquid C: glucose, citric acid Sodium, Sodium Chloride, Penicillin, Glycerin, Coco Monoethanolamide, Sodium Lauryl Sulfate, Triethanolamine, Hydrochloric Acid, Distilled Water; Liquid D: Anhydrous Citric Acid, Caffeine g, Tris, Carbonic Acid Sodium hydrogen, disodium ethylenediaminetetraacetic acid, sodium pyruvate, glucose; each raw material was dissolved in 100ml of double-distilled water to make four kinds of dilutions, the pH value was adjusted to 6.5-7.5, and refrigerated in the refrigerator. The product of the invention is used for cryopreservation of porcine semen dilution.

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...
