[0002] Cattle breeding refers to the purposeful selection and improvement of cattle herds through genetic principles, biotechnology and scientific feeding and management methods, in order to improve the genetic quality, production performance and adaptability of the breeding cattle population and meet the demand for high-quality breeding cattle resources in animal husbandry production.

[0003] The existing bovine exoembryo freezing device can quickly refrigerate the bovine exoembryo in the container by placing the container containing the bovine exoembryo into the interior of the freezing device and then using the cooperation of the induced draft fan and the condenser to allow cold air to be evenly blown toward the container containing the bovine exoembryo. However, in actual use, the blowing angle of the cold air is mostly fixed, so that different bovine exoembryo containers are exposed to different amounts of cold air, and thus the bovine exoembryo containers in use cannot be quickly cooled at the same time, resulting in a poor cooling effect.
