Embodiment approach 1

[0027] Implementation mode one: if Figure 1-5 As shown, the insemination gun for donkeys includes a sleeve 1 and a push rod 2. A sleeve head 11 is sleeved on the front end of the sleeve 1. The inner end surface of the sleeve head 11 is arc-shaped, and the apex is provided with a sperm discharger. Hole 12, the rear end of sleeve 1 is socketed with a flange 13; the front part of the push rod 2 is inserted into the sleeve 1, the rear end of the push rod 2 is provided with a push handle 21, and the front end of the push rod 2 is provided with a push pin 3 , the push pin 3 can be inserted into the donkey semen thin tube 4, one end of the donkey semen thin tube 4 is a closed end, and the other end is plugged with a tampon end of a tampon, it is characterized in that: there are N total of the push pins 3, and the push rod 2. The front end is an enlarged part 22, and the push pin 3 is arranged on the enlarged part 22, N is an integer, and 3≤N≤8. Figure 1-5 where N is 5.

Embodiment approach 2

[0038] Implementation mode two: if Figure 6-8As shown, it also includes a porous sleeve 6, the main body of the porous sleeve 6 is cylindrical, the outer diameter of the porous sleeve 6 is smaller than the inner diameter of the sleeve 1, and a plurality of annularly distributed stepped through holes 61 are opened in it. The hole 61 is sleeved on the donkey semen capillary 4, and the above-mentioned stepped through hole 61 is in one-to-one correspondence with the pins 3 on the push rod 2 (that is, the number is the same, and the positions are corresponding). Each stepped through hole 61 is made up of a blind hole 610 and a small through hole 611. The small through hole 611 is opened in the center of the blind hole 610, and a stepped platform 612 is formed at the bottom of the blind hole 610. The small through holes of all the stepped through holes 61 The holes 611 are located at the front of the porous sleeve head 6, and the outer edge of the front end of the porous sleeve hea...

Abstract

The invention relates to a semen deposition gun for a donkey and an application method thereof. An existing fine type semen deposition gun can be used for injecting a donkey semen deposition fine pipe, so as to improve the cost and work amount. Therefore, the donkey semen deposition gun comprises a sleeve and a push rod, wherein the front end of the sleeve is connected with a sleeve head, the inner end plane of the sleeve is in an arc shape, and a semen outlet hole is formed in the top of the sleeve head, and a flange sleeves the rear end of the sleeve; the front part of the push rod is inserted into the sleeve, the rear end of the push rod is provided with a push handle, the front end of the push rod is provided with a push needle, and the push needle can be inserted into the donkey semen deposition fine pipe; one end of the donkey semen deposition fine pipe is a closed end, and the other end of the donkey semen deposition fine pipe is a cotton plug end plugged with a cotton plug. The semen deposition gun is characterized in that the number of push needles is N, the front end of the push rod is an expansion part, and the push needle is arranged on the expansion part, N is an integer and is not less than 3 and not more than 8. The semen deposition gun provided by the invention has the characteristics of high pregnancy rate, controllable semen volume, convenience in operation and sanitation and hygiene, thereby being very applicable to the artificial insemination of the donkey.

Description

technical field [0001] The invention relates to a breeding instrument for artificial insemination of a female donkey in estrus, in particular to a donkey semen thin-tube insemination gun and a use method thereof. Background technique [0002] Artificial insemination technology has been widely used in modern aquaculture, and has the advantages of high breeding efficiency and easy breeding of fine varieties. [0003] The existing insemination guns for donkeys are all push rods with push pins at the front end, which push and inject the donkey semen stored in the polypropylene straw into the body of the female donkey. The polypropylene straw for storing donkey semen is called a donkey semen straw, which has a limited capacity and can only inject a small amount of donkey semen into the female donkey at a time, resulting in a low pregnancy rate. A female donkey often needs multiple inseminations to conceive. The operation is cumbersome, which increases the risk of artificial ins...
