The use of cryotechnology is by no means limited to human medicine. In veterinary medicine, cryopreservation has an equally long and important tradition. The controlled freezing and storage of animal sperm, embryos and tissue samples is a cornerstone of modern animal breeding, species conservation programs and veterinary research.
The requirements for cryostorage in veterinary medicine differ to some extent from those in human medicine - particularly in terms of volumes and logistics. In this article, we highlight the most important fields of application and show how Consarctic® also provides support in this area with customized solutions.
The cryopreservation of semen is the oldest and most widespread application of cryotechnology in veterinary medicine. It was established for cattle back in the 1950s and has revolutionized advanced animal breeding.
Artificial insemination (AI) with cryopreserved semen is the global standard in cattle breeding. A single ejaculate from a breeding bull can be divided into hundreds of straws (sperm portions) and stored for decades. This enables targeted genetic selection and the international exchange of genetics without having to transport the animals.
Sperm cryopreservation is also becoming increasingly important in horse breeding, although horse sperm is more sensitive to the freezing process than bovine sperm. Optimized freezing protocols and high-quality freezers are continuously improving the success rate.
Cryosperm is also used in pig breeding, and specialized preservation protocols also exist for poultry breeding. The challenge here lies in the species-specific requirements for the CPA composition and the cooling rate.
In addition to sperm, animal embryos are also cryopreserved. Embryo transfer involves transferring a genetically valuable embryo into a recipient mare or cow. Cryopreservation allows the timing of the transfer to be flexible and embryos to be sent internationally.
Dry shippers such as the Consarctic® ASR+ series are used for the international shipment of cryopreserved embryos and sperm. They ensure that the cold chain is maintained during transportation and meet air freight requirements.
One particularly forward-looking area is the use of cryopreservation for the protection of endangered species. Gene banks - sometimes referred to as frozen zoos - store sperm, eggs, embryos and tissue samples from endangered species as a genetic reserve.
The best-known example is the Frozen Zoo® collection of the San Diego Zoo Wildlife Alliance, which comprises cryopreserved cell material from over 10,000 individuals and almost 1,200 species. Similar initiatives exist worldwide, including at the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin.
The storage of these irreplaceable samples requires cryogenic containers of the highest reliability. A failure of the storage system could mean the irretrievable loss of genetic resources that could be crucial for future species conservation programs.
In veterinary research, tissue samples, cell cultures and biological materials are cryopreserved in order to keep them available for later analysis. The requirements are similar to those of human medical research: validated freezing processes, complete documentation and secure long-term storage.
Consarctic® offers veterinary institutions, breeding organizations and conservation programs a comprehensive portfolio of cryoproducts:
Whether for efficient animal breeding, the protection of endangered species or advances in veterinary research - cryopreservation is an indispensable tool. And the quality of the technology used determines how effective this tool can be.
