Insemination equipment for Hu sheep estrus synchronization artificial insemination

Abstract

The invention discloses insemination equipment for Hu sheep estrus synchronization artificial insemination, which comprises an inner cylinder, an outer cylinder sleeved outside the inner cylinder, a first piston arranged in the inner cylinder, a second piston arranged in the outer cylinder, and a piston rod for connecting the first piston and the second piston, the outer cylinder is provided with a scale device matched with the second piston and a supporting frame for supporting the outer cylinder, the scale device comprises at least one groove and at least one protruding block arranged in the groove, and the second piston makes contact with the protruding block. Through the mutual cooperation of the second piston and the protruding block, when the second piston passes through the first protruding block, the second piston collides with the protruding block to generate a certain blockage, and a blockage operator can feel the blockage, so that the operator is reminded of the input quantity, repeated checking is not needed, and the operation is more convenient and faster.

Description

technical field [0001] The invention belongs to the technical field of insemination of Hu sheep, and in particular relates to an insemination device for artificial insemination of Hu sheep with simultaneous estrus. Background technique [0002] Hu sheep is an important local breed. It is also a first-class protected local animal breed in my country. Hu sheep breeding also has important significance and economic benefits. Breeding is a particularly important task in the breeding process. In order to ensure timely mating of Hu sheep, We must insist on using trial sheep to test the ewes sooner or later. When the ewes are found to be in estrus, they are bred immediately, and the ewes are bred once at an interval of 8-10 hours. [0003] At present, in the existing insemination of Hu sheep, the insemination volume of each sample is guaranteed to be 0.5-1 ml, and the effective number of spermatozoa in one insemination is guaranteed to be more than 20 million. There are certain requ...

Problems solved by technology

[0003] At present, in the existing insemination of Hu sheep, the insemination volume of each sample is guaranteed to be 0.5-1 ml, and the effective number of spermatozoa in one insemination is guaranteed to be more than 20 million. There are certain requirements for the amount of sperm input. It is usually used to mark the scale on the semen cylinder to observe the input of semen, which makes the data not accurate enough, and the operator needs to look at the scale repeatedly, and the operation process is complicated
