Description

Technical Field

[0001] The utility model relates to the field of artificial insemination of ewes, in particular to a restraining frame used for artificial insemination of ewes. Background Art

[0002] With the development of modern farming and animal husbandry technology, in order to increase the reproductive capacity of livestock, people use artificial insemination technology to breed sheep. At present, sheep artificial insemination is basically done by people holding down the sheep for artificial insemination. This operation is not easy to control the sheep's body, and it is difficult to keep the sheep's body still during artificial insemination. The operation is more difficult and the success rate of artificial insemination is low. Because it is inconvenient for people to hold the sheep, sometimes people get injured.

[0003] After searching the Chinese patent, a restraining frame for artificial insemination of ewes (Announcement No. CN202497264U) was found, which includes a sheep bed, an outer frame, a fixed vertical rod, a fixed horizontal rod and a movable neck yoke. The movable neck yoke includes a neck yoke horizontal rod and a neck yoke vertical rod. The neck yoke horizontal rod and the neck yoke vertical rod, as well as the neck yoke vertical rod and the fixed sheep bed are all movably connected; the sheep bed includes a fixed sheep bed and a movable sheep bed. The fixed sheep bed is provided with a restraining fence, and the fixed sheep bed and the movable sheep bed are movably connected; the tail of the movable sheep bed is provided with a pulling component for lifting the movable sheep bed. The utility model is convenient for fixing and clamping sheep, and can fix the sheep's head and conveniently fix the sheep in the restraining frame. The sheep can remain fixed during artificial insemination, which is convenient for insemination operation; at the same time, the rear end of the movable sheep bed can be lifted to raise the sheep's buttocks to prevent semen from flowing back, which is beneficial to the success rate of insemination. Multiple neck yoke vertical rods and fixed vertical rods can be set to inseminate multiple sheep at the same time, which is very useful for artificial insemination of ewes in large-scale sheep breeding farms. It is easy to use, low in cost, strong in practicality, and easy to promote and apply.

[0004] The above patent can raise the buttocks of the sheep to prevent semen from flowing back, which is beneficial to the success rate of insemination; however, manual adjustment is required to fix the ewe, which is not simple enough. In addition, the hind half of the ewe is suspended, which results in the hind half of the ewe not being effectively cushioned, causing discomfort to the ewe.

[0005] Therefore, it is necessary to invent a restraining frame for artificial insemination of ewes to solve the above problems. Utility Model Content
