Novel bovine embryo transplantation gun capable of bending and stretching forwards along with uterine horn

Abstract

The invention discloses a novel bovine embryo transplantation gun capable of bending and extending forward along with the uterine horn, and relates to the field of embryo transplantation guns, the novel bovine embryo transplantation gun comprises a gun barrel, a gun core and a culture solution thin tube, the culture solution thin tube is installed in a barrel hole in the inner end of the gun barrel in a matched mode, a piston is arranged in the culture solution thin tube, and the gun core is arranged in the gun barrel. According to the invention, an embryo in the slim tube is pushed into the extension catheter through the piston, and then the piston is punctured through the hollow steel needle to be communicated with the inner cavity of the slim tube; an operator pushes a piston handle of the injector to enable gas in the injector to enter the extension catheter through the hollow steel needle, and an embryo in the extension catheter is driven into the uterine horn of a cattle by the gas, so that the problem that the embryo cannot be driven into the uterus by a gun core after a slim tube is connected with the extension catheter is solved, and the operator does not need to grab the front end of the uterine horn; the operation difficulty is greatly reduced, the use of operators is facilitated, and the conception rate is indirectly improved.

Description

technical field [0001] The invention belongs to the field of embryo transfer guns, and in particular relates to a novel embryo transfer gun for cattle that can bend and protrude along with uterine horns. Background technique [0002] Due to the high economic value of cattle, which are single-born animals, the number of litters is small, the breeding cycle is long, and there is no seasonality in breeding, the whole process of embryo transfer can be performed non-surgically, and the donor cattle can be used repeatedly. Therefore, the embryo transfer technology of cattle Relatively fast development. This technology can greatly increase the number of offspring of fine-bred cows, and has broad application prospects in the current situation of shortage of high-yield dairy cows and pure-bred beef cattle in my country. [0003] At present, when carrying out embryo transfer to cattle, the operator usually uses a linear rigid embryo transfer gun. When performing embryo transfer, the ...

AI Technical Summary

Problems solved by technology

[0006] In view of the inconvenience, time-consuming and labor-intensive operation of the current operators when using the insemination gun, it is easy to cause damage to the cattle and affect the fertility rate of cattle and the survival rate of calves Problem, the present invention provides a new type of embryo transfer gun for cattle that can bend forward with the uterine horn
