Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of artificial semen collection devices for sheep, and particularly relates to a sheep bionic semen collection device. BACKGROUND

[0002] Artificial insemination technology has very obvious effects on improving the utilization rate of male animals, accelerating breed improvement, reducing feeding and management costs, preventing disease transmission, improving conception rate, and performing long-distance exchange and transportation, and is an important technical means for realizing the scale and intensive production of livestock and poultry. Semen collection is one of the key procedures of artificial insemination, and needs to be guaranteed in terms of full amount, original quality, no damage, and simple operation.

[0003] At present, the traditional semen collection method for sheep mainly adopts a false vagina method. The main principle is to induce the erection of a male sheep, insert the penis of the male sheep into a semen collection device, and perform semen collection operation. The method is simple and fast, but the traditional semen collection device is composed of a shell, an inner tire, and a semen collection cup. When in use, water needs to be injected into the inner tire, and then the inner tire is blown up or inflated by mouth. The process is complicated, heat loss is easy to occur, and the semen collection temperature is difficult to control. Especially in winter, the temperature of semen collection decreases with time, the penis of the male sheep contracts due to cold stimulation, and semen cannot be collected. Even if semen is collected, the male sheep will be adversely stimulated. Moreover, the pressure generated by each inflation is different, and the male sheep feels differently about the pressure, which is difficult to meet the needs of the male sheep for ejaculation. Temperature and pressure can also cause the male sheep to repeatedly mount or incompletely ejaculate, affecting the semen collection speed and quality. Moreover, the inner tire and the semen collection cup are repeatedly used in use, and need to be strictly cleaned and disinfected before each use. If disinfection is not thorough, human and animal pathogenic microorganisms will be infected. SUMMARY
