Description
Technical field
The present invention relates to technical field of animal reproduction, and in particular to a kind of method that flock of sheep are carried out with continuous semen deposition.
Background technology
China's tradition sheep husbandry is all based on peasant casual household, is improved recently as social development and environmental requirement, is supported
Sheep industry develops to scale and intensive direction, sheep raising field using the modes such as artificial insemination come reduce labor intensity, save into
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 is very ripe and general
Time species it is not quite alike, the artificial insemination success rate of sheep is very low, and its reason is primarily due to the reproductive organs of ewe first
Construction is more special, can numerous ewe vagina it is longer, mostly more than 10-14cm, 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 ratio of closing error is tighter, even in heat
When, also simply somewhat open 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, Ran Houyong as operator under lighting
1ml disposable syringes connect sheep insemination needle or glass inseminating syringe carries out semen deposition.It is real but existing sheep insemination needle is more elongated
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 soft, it is not easy to puts forth effort, what can be puted forth effort is glass inseminating syringe, but existing glass semen deposition
Device, or vas deferens is too short, cervical orifice is reached in operation, or front end is all straight pipe type, ransacing the free of softness
In the ewe cervix and cervical orifice of vagina end, it is not easy to operate successfully, because most of ewe cervixs have necessarily
Flexibility, it is accurate that insemination site is not easy to hold.
In addition, current livestock reproduction inseminating syringe, either by freezing, fine tube determines semen deposition dosage or armrest promotes note
Emitter determines, be all with feel and inseminating syringe on scale determine, and in practical operation, ewe struggle ratio during due to artificial insemination
More severe, armrest is dynamic to be difficult to hold accurate semen deposition dosage.The artificial insemination of sheep, because success rate itself is just than relatively low, and
Outstanding ram quantity is seldom, to ensure quality of inseminating, is typically chosen after the fresh essence now penetrated using ram is diluted at once to mother
Sheep inseminates, and is hundreds of even thousands of in the general ewe quantity of scale raising, ewe quantity is more, and outstanding ram quantity
With regard to limited, and ejaculation amount is just to dilute also only about 4ml in 0.5ml -2ml, generally 1ml, 4 times of row to ram every time, and in ewe
Reach tens of when concentrating heat, every ewe can only defeated 0.1-0.2ml it is even less, if moved without the pure armrest of control measure
Control, it is easy to just the standby seminal fluid store in smart device is pushed away quickly and is over, so, for improve the utilization rate of outstanding stud ram and
Artificial insemination conception rate, it is artificial to carry out sheep using a kind of easy to operate, semen deposition dosage and the accurate semen deposition apparatus in insemination site
Semen deposition operation of inseminating is necessary.

Body front end needle portion is bending segment, length 1.5-2.0cm, is made progress than straight tube inseminating syringe, but is existed during actual use
Problems with:The larger sheep vagina of build first is also long, and also needs to ransack cervix, and the inseminating syringe needle body length is not
It is enough, and vas deferens with syringe piston in line, piston armrest promotes, thus when operating hand with vas deferens in a straight line
On, just obstructed the view when ransacing cervical orifice, when operating big build sheep, because the inadequate needle body part of length may
To enter vagina, hand is easy to touch vagina, is also easier to shelter from sight, and great inconvenience is brought to operation；Secondly
Pain ewe is easily touched when the bent angle of syringe needle bending segment touches ewe vaginal wall and uterine wall in operation, causes ewe bigger
Stress reaction；The dynamic scale with sensation and needle tubing of other inseminating syringe or armrest determines semen deposition dosage, in practical operation
Extremely difficult accurate control insemination dose；And the inseminating syringe does not have lighting installation, two people are still needed using the inseminating syringe, one
Individual's illumination, people's operation.
Ewe estrus duration is shorter, therefore typically can all have several when concentrating heat in scale sheep raising field, ewe
Ten sheep heats simultaneously, if the operating time is long during every sheep artificial insemination, can lead to miss the oestrus of a part of sheep, or
Person was just inseminated in the heat later stage, and conception rate is low, caused these ewes before next oestrus nonpregnant can only raise,
Feeding cost is wasted, therefore, it is to reduce nonpregnant ewe that artificial insemination efficiency is improved in ewe oestrus, improves sheep raising field
One approach of benefit.
