Liquid nitrogen tank to help the development of animal husbandry

What exactly is the role of liquid nitrogen tanks in the development of animal husbandry? Liquid nitrogen tanks in the livestock industry is mainly used in frozen embryos, cryo preservation of fine varieties, mainly for pigs, cattle, sheep and other male sperm preservation and transportation. Currently frozen semen, artificial insemination technology has been commonly used in livestock production. The temperature of liquid nitrogen is -196℃, which is the most ideal cryogenic agent for preserving frozen semen, and the liquid nitrogen tanks used for storing frozen semen have also become essential containers in breeding production. In addition, liquid nitrogen tanks can also be used to preserve strains, vaccines and other biological samples, which protects the high-quality development of the animal husbandry industry.
                               
Providing containers for cattle and sheep frozen semen storage

This is one of the more widely used liquid nitrogen tanks in animal husbandry, and it is also the mainstream way of frozen semen storage for cattle and sheep. Liquid nitrogen tanks store liquid nitrogen at -196℃, which will quick-freeze the semen of cattle and sheep to achieve the purpose of frozen semen storage without harming the biological activity.

Frozen semen of cattle and sheep is stored with liquid nitrogen as the cold source and can be taken out at any time when needed. In order to prevent the influence of temperature change on semen quality, the action of taking and putting should be rapid and minimize the time staying in the air. When the frozen semen is extracted from the storage container, the semen should not exceed the base of the neck of the liquid nitrogen container, so as to avoid the decline of semen thawing viability due to the rise in temperature. The frozen semen of cattle and sheep has a history of more than 40 years. Tests have proved that the frozen semen preserved to date still has the ability to inseminate. However, it is generally believed that with the prolongation of the preservation time of the frozen semen of cattle and sheep, the viability and insemination ability of spermatozoa gradually decrease. The exact time limit for long-term preservation of bovine frozen semen needs to be studied and observed.

                                   
Preservation of animal vaccines

Some animal vaccines that require low-temperature storage can be put into liquid nitrogen tanks for long-term preservation. For example, the chicken Marek's liquid nitrogen vaccine can only be stored in liquid nitrogen at -196 degrees Celsius, and it must be placed in the liquid nitrogen tank when it leaves the factory. When you use it, thaw it quickly with warm water at 38 degrees. To ensure the viability of the cells. Use with matching vaccine diluent.
