Sow artificial insemination aid

Abstract

The invention discloses a sow artificial insemination aid, which is of a structure characterized in that an upper small ring and a lower part opened large ring are integrally formed by a flexible rod element; the upper small ring and the lower large ring form a crossed pivoting point, i.e., a left arm of the small ring is connected with a right arm of the large ring; a right arm of the small ring is connected with a left arm of the large ring; an opening of the large ring is formed in the bottom, so that the large ring forms an opening clamp; the opening clamp corresponds to the arc shape of the back of a sow and is provided with two end feet; and a driving device for driving the small ring to generate discontinuous deformation is arranged in the small ring. The driving device is started to push the left arm or / and the right arm of the small ring to repeatedly act; further, the two end feet of the large ring are driven to inwards and outwards swing so that the mating action of a boar and the sow is simulated; the estrus of the sow is further induced; and the functions of promoting ovulation and improving the pregnancy rate are achieved.

Description

technical field [0001] The invention relates to an artificial insemination technology for sows, in particular to an artificial insemination assistant for sows. Background technique [0002] Artificial insemination of sows is an important technology developed in recent years. It involves the technical links of modern large-scale pig raising. It directly determines and improves the economic benefits and development of pig raising enterprises. In the case of small breeding difficulties, it can reduce the spread of diseases, and can also greatly improve the reproductive efficiency of pigs, achieve resource sharing, and play an important role in the purification of pig farm diseases. [0003] At present, artificial insemination of sows is carried out when sows are in estrus, but due to the passive nature of artificial implementation, the pregnancy rate of sows cannot achieve the desired effect; how to make sows use their own reactions is the key to improving their pregnancy rat...
