Problems solved by technology

[0003] However, due to the constraints of complicated work procedures and various insemination tools, this technology cannot be effectively promoted in the vast number of rural scattered farmers. 》Solved many problems such as difficulty in keeping fresh semen, inconvenient carrying, infusion of semen and multiple locks, and low conception rate for the majority of scattered sheep farmers

Embodiment Construction

[0008] The present invention will be further described below with specific examples.

[0009] Take a disposable polyethylene tube with a diameter of 4.5MM and a length of 25CM, seal one end with a sealing machine, then use a 1ml syringe to inject 0.4ml of ram semen into the middle of the tube, seal the other end of the tube, and finally put it in 17°C Store in a constant temperature water tank.

[0010] After the ewes in the estrous adaptation period are subjected to necessary disinfection treatment, 10 units of oxytocin is injected into the ewe's vagina 15 minutes before the insemination of the ewe, and the back of the sheep is close to the chest of the assistant, and the two sides are lifted. The method of securing the hind legs, dragging the tail to the left rear of the sheep at the same time, the inseminator holds the ram semen strip and cuts one end for ventilation, and faces the vulva opening of the ewe, opens the labia with the left hand, and inserts the sheep semen str...

Abstract

The invention relates to a self-manufactured disposable semen strip used for sheep and a simple insemination method. The method for manufacturing the disposable semen strip includes the steps that one end of a disposable polyethylene tube is sealed by a sealing machine, wherein the diameter of the polyethylene tube is 4.5 mm, the length of the polyethylene tube is 25 cm, a 1-ml injector is used for taking 0.4 ml of ram semen and injecting the ram semen into the middle of the tube, then the other end of the tube is sealed, and the tube is placed into a water tank at the constant temperature of 17 DEG C to be saved. The simple insemination method of the self-manufactured disposable semen strip includes the steps that a insemination worker holds the ram semen strip with the hand, cuts one end of the ram semen strip open for ventilation, inserts the ram semen strip by about 15 mm, slightly draws the ram semen strip back and forth five times, and finally cuts the other end of the ram semen strip open, and at the moment, semen will be automatically sucked into the cervical orifice. The self-manufactured disposable semen strip is low in cost and easy to operate, the insemination conception rate of ewes is over 85%, productivity is greatly improved, and the self-manufactured disposable semen strip is suitable for vast scattering raising households in the rural areas and convenient to popularize in a large-area mode.

Description

technical field [0001] The invention relates to sheep artificial insemination and the production of ram semen strips, belonging to the technical field of sheep reproduction. Background technique [0002] Artificial insemination of sheep emerged in the late 1920s, and by 1940 it had spread all over the world. Due to the economy, rapidity and high efficiency of this technology, it has been vigorously developed in livestock breeding and widely used in production. It has outstanding advantages in many aspects such as disease prevention and control, cost saving, and breed improvement. With the improvement of people's living standards, the demand for sheep products is also increasing, and the status of sheep in livestock products is also rising. Breed improvement and artificial insemination are also more and more valued by the people of the country. [0003] However, due to the constraints of complicated work procedures and various insemination tools, this technology cannot be ef...
