Abstract

A sterile insertion method of a seminiferous duct for artificial insemination of pigs comprises four steps as follows: material selection, material assembly, preparation before insertion of the seminiferous duct and insertion of the seminiferous duct. According to the scheme, the inlet end, where a rubber head is arranged, of the seminiferous duct is wrapped with an aseptic bag, so that the seminiferous duct is prevented from being contacted with the outside when the seminiferous duct is inserted into the front end of the vagina of a sow, and the womb of the sow is prevented from being infected by bacteria carried by the seminiferous duct. The rubber head at the inlet end of the seminiferous duct is wrapped in the aseptic bag by a flexible rubber band, the aseptic bag is folded to sleeve the seminiferous duct, after the seminiferous duct is inserted into the vagina of the sow, the aseptic bag is pulled manually to keep static, and the seminiferous duct is continuously pushed until the seminiferous duct enters the cervix of the womb or the womb of the sow without carrying bacteria. According to the technical scheme, the sterile insertion method has the advantages of convenience in operation, simplicity in material selection, low requirement for washing of the vulva of the sow and good anti-infection effect.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry artificial insemination, and relates to a vas deferens insertion method, in particular to an aseptic insertion method of a pig vas deferens for artificial insemination. Background technique [0002] At present, the application of artificial insemination technology has played an important role in the improvement and cultivation of pig breeds in my country, and it is an indispensable key technology in pig breeding. Under good feeding and management conditions, the pregnancy rate of pigs in estrus can reach more than 50%, and the total annual conception rate can reach 85% to 90%, or even more than 95%. However, artificial insemination has very strict requirements on operating conditions. If improperly operated, it will cause low conception rate of pigs and even cause reproductive diseases. In the pig artificial insemination technology, in order to avoid contamination of the insemination gun...
