Animal Husbandry



      Liquid nitrogen tanks have been widely used in the animal husbandry market, mainly reflected in the storage of animal semen, the preservation of embryonic cells in the bioengineering industry, and the use of liquid nitrogen to treat the closure of the external orifice of the bovine nipple and the bovine skin tumors.
Artificial insemination technology is an important and practical fast technology for cattle breed improvement. It can not only give full play to the utilization rate of excellent breeding bulls, but also save a lot of investment in purchasing breeding bulls. Dairy cows bred through AI will produce calves with good genetic quality according to the preferences and choices of producers. In addition, artificially inseminated cows calve more prematurely, resulting in an increase in calving interval and weaning weight of cows. Therefore, they are popular with many farmers. The main links are the breeding of bulls, semen collection, semen freezing, packaging and storage of frozen semen, and the use and breeding of frozen semen. In this application, the essential equipment is the liquid nitrogen tank for storing the semen of breeding cattle.

      Bovine semen must be stored at - 196 ° C to ensure the vitality of sperm during transportation and storage. Liquid nitrogen tanks are responsible for long-term preservation and storage, which has promoted the use of artificial insemination in many livestock farms around the world.

The liquid nitrogen used to store bovine semen freezes the semen for storage and can be taken out at any time when necessary. In order to prevent the influence of temperature change on semen quality, it is necessary to act quickly when placing and extracting. When extracting frozen semen from the storage container, the semen should not cover the bottom of the liquid nitrogen container to prevent the semen from melting due to temperature rise. The frozen semen of cattle has a history of more than 40 years. The experiment proved that frozen semen still has the ability of fertilization. However, it is generally believed that with the prolongation of survival time, the sperm viability and fertilization ability of bovine frozen semen gradually decrease.

      How should people in the livestock industry choose suitable liquid nitrogen tanks?

      Liquid nitrogen tanks need to be stored in a elevated surface, well-lit and well-ventilated area, such as wooden pallets. Direct contact with concrete or floor will corrode the aluminum shell of liquid nitrogen tank. Therefore, the size of the tank can be determined by determining the storage location of the tank. In addition, a key factor to consider is the diameter of the neck opening of the can. The larger the diameter of the liquid nitrogen tank, the easier it is to pull out the frozen fine tube, but the larger the diameter of the liquid nitrogen tank needs to be filled with liquid nitrogen more frequently, because each time the tank is opened, more liquid nitrogen will be lost. By contrast, the small-caliber liquid nitrogen tank is very suitable for those with rich experience in semen treatment, and increases the time between refilling.

      Our company recommends the following models for your reference:
YDS-10-50/80, YDS-15-50/80/125, YDS-20-50/80/125, YDS-30-50/80, YDS-35-50/80/125, YDS50-50/80/125 and other models above 50L.

      ZPX liquid nitrogen tank can provide longer hold times for extended-term storage at cryogenic temperatures to ensure that the biological samples in the tank are not damaged, and even improved sample viability and increased productivity.
