Sheep industry develops to scale and intensive direction, sheep raising field reduced using modes such as artificial insemination labor intensity, saving at
Originally, productivity effect is improved with regard to particularly important.But the technology of artificial insemination such as this species of sheep and pig, ox are very mature and general
Time species it is not quite alike, the artificial insemination success rate of sheep is very low, and reason is primarily due to the reproductive organs of ewe first
It is more special to construct, can numerous ewe vagina it is longer, mostly 10-14cm or more, and cervix is free on intravaginal, the uterus of sheep
Neck is very thin, and diameter is generally 1.2-1.7cm, and cervical orifice is different, and cervical orifice closure is tighter, even if in heat
When, it also only slightly opens a bit, collar extension is extremely shallow.And sheep artificial insemination mainly struts ewe vagina with prolapsus appliance at present, one
People is shone with illuminations, and another people finds the cervix for being free in intravaginal under lighting, then use as operator
1ml disposable syringe connects sheep insemination needle or glass inseminating syringe carries out semen deposition.But existing sheep insemination needle is more elongated, it is real
It is not easy to put forth effort in the operation of border, because cervical orifice can just be seen by sometimes needing to dig cervix to have some, and it is elongated
Insemination needle end is softer, it is not easy to put forth effort, what can be puted forth effort is glass inseminating syringe, but existing glass semen deposition
Device or vas deferens are too short, and cervical orifice is reached in operation or front end is all straight pipe type, are ransacing soft dissociate
