The method comprises the following steps that S1, a sperm conveying worker treads on the nape of the female muscovy duck to pacify the female muscovy duck; S2, the sperm conveying worker presses tail feather of the female muscovy duck with a left hand to expose the anus of the female muscovy duck; S3, the sperm conveying worker holds a sperm-containing sperm conveyor with the right hand and pushes 3 to 5cm along the bottom left of the opening of the anus; S4, the sperm conveying worker presses the sperm conveyor with right hand to finish sperm conveying. According to the technical scheme, the method has the advantages that the action characteristics of the female muscovy duck under natural matching condition are imitated on the basis of the structures of reproductive system and digestive system and the physiological characteristics of the female muscovy duck, and therefore, the complex, difficultly-learnt and difficultly-operated processes of overturning the anus or probing into the vagina with finger can be saved.
Description
Technical field
The present invention relates to cultural technique field, be specifically related to one and lay eggs a kind duck artificial insemination method.
Background technology
Muscovy duck is subject to the favor of consumer deeply with the fragrance of its uniqueness, low fat.Due to the improvement of breeding technique, the body weight of planting drake is increasing, causes the difference between male and female duck body weight to increase, and pure natural mating mounting difficulty is large, and the production cost of raising a large amount of drake is high, therefore still takes the method for manually turning over anus semen deposition to breed in large production.
What use for many years manually turns over anus semen deposition method, requires that operator right-hand man firmly coordinates simultaneously, fully opens the duck vaginal orifice at cloaca back.The major defect existed has: 1, technical requirement is high.It is comparatively large that anus operation easier is turned in new hand's study, usually needs study, puts into practice several months to half a year and turn over anus action; 2, labor efficiency is low.Common artificial insemination personnel, every day transmission & distribution 600-700, even be familiar with the master worker of operation, working every day is also systemic pain, general 800 of day semen deposition duck, maximum 1000; 3, turning over anus stress be large.When turning over anus, intrarectal duck excrement is forced and is gushed out, vaginal mucosa because of outside being exposed to, easy bacteria infection and inflammation.Turn over anus semen deposition when do not produce finished in the morning, the lighter racks intratubal hard shelled egg, and cause kind of duck behind peak of laying eggs because salpingitis tubal causes hatching egg to enter to incubate rate obviously and continuous decrease, be also difficult to recover until eliminate, severe one causes duck dead because of peritonitis; 4, rate of fertilization continues to drop.Because not turning over the not defeated essence of laying ducks of anus, have existence when causing leaking defeated phenomenon, some unskilled personnel's semen deposition operations are rough in addition, the inflammation of tunica mucosa tubae uterinae can hardly be avoided, sperm moves ahead and is obstructed, and causes duck with the prolongation of laying eggs age in week, produce fertility rate of hatching egg and constantly decline; 5, adopt the semen deposition of glass looper, there is the artificial property of semen deposition dosage comparatively strong, input every oviducal semen dosage of duck inconsistent, affect rate of fertilization, and spermatic gun head is not changed, and easily fractures, increase cost and occur cross infection; 6, to turn over after anus vagina and vaginal orifice down, the seminal fluid of input easily flow backwards a small amount of out, affect fertility rate of hatching egg.
Finger probes into vaginal-insemination technique, and not only semen deposition efficiency is low, and patient's finger stretches into intravaginal repeatedly, points the cross infection vagina that easily carries disease germs, and increases infection risk, therefore seldom uses in producing greatly.
Summary of the invention
The present invention is intended to solve the problem to a certain extent, at least provides a kind of coml to apply.
For this reason, the object of the invention is to the defect overcoming prior art, a kind of safety, efficient kind of duck artificial insemination method are provided.
For achieving the above object, the present invention is by the following technical solutions: an a kind of kind duck artificial insemination's method of laying eggs, comprises the following steps:
S1. semen deposition personnel tramp with one's feet the nape portion of kind duck, and kind duck is stabilized;
S2. semen deposition personnel are with left hand pressing kind duck tail feathers, make a kind duck expose anus;
S3. semen deposition personnel advance 3-5 centimetre with the semen deposition utensil that the right hand is held containing seminal fluid along anal orifice lower left;
S4. semen deposition personnel are with right hand pressing semen deposition utensil, complete semen deposition.
The technical program is according to kind kind duck reproduction, digestive system structure and physiological characteristics, imitate the acting characteristic under kind of Muscovy duck natural mating situation, save numerous and diversely to find it difficult to learn, difficult operation turn over anus or finger probes into vagina process, operator's left hand presses duck tail feathers gently, expose anus, the right hand holds the semen deposition utensil containing seminal fluid, and spermatic gun head per anum doorway lower left is entered fallopian tube portio vaginalis, very safe and efficient.
Further, in described step S4, insemination dose is that 0.1ml dilutes seminal fluid, or the former seminal fluid of 0.05ml, can ensure enough effective sperm quantities.
Further, the time of described artificial insemination is 9:00-16:00 every day, and the comparatively hard shelled egg existed in fallopian tube back segment can be avoided to hinder sperm to move ahead.
Further, at interval of 4 days artificial inseminations once.Test proves, twice the interval between insemination is shorter than 4 days, both wastes seminal fluid, and increases labor cost again; Be longer than 4 days, intratubal effective sperm count is fewer and feweri, and rate of fertilization declines.
The invention has the beneficial effects as follows,
Patent of the present invention need not turn over anus or finger probes into, and just can learn semen deposition personnel half a day and be familiar with kind of a Muscovy duck artificial insemination to operate, and learns than turning over the shortening of anus semen deposition method and is not familiar with 3 months time-half a year not etc.; Can direct semen deposition because anus need not be turned over, duck stress be less, and employee need not again with turning over anus energetically, and operation is very easily efficient, and semen deposition speed is obviously accelerated, duck by enclose squeeze stack be subject to together stress time obviously shorten.Everyone can reach 3000 by semen deposition every day duck, improves effect about 2 times.
Accompanying drawing explanation
Fig. 1 is the gonotyl composition of kind duck.
Detailed description of the invention
The present invention is described in detail below in conjunction with accompanying drawing.
A kind duck artificial insemination's method of laying eggs of the present invention, according to kind kind duck reproduction, digestive system structure and physiological characteristics, imitate the acting characteristic under kind of Muscovy duck natural mating situation, carry out semen deposition to kind duck, concrete steps are as follows:
S1. semen deposition personnel tramp with one's feet the nape portion of kind duck, and kind duck is stabilized;
S2. semen deposition personnel are with left hand pressing kind duck tail feathers, make a kind duck expose anus;
S3. semen deposition personnel advance 3-5 centimetre with the semen deposition utensil that the right hand is held containing seminal fluid along anal orifice lower left;
S4. semen deposition personnel are with right hand pressing semen deposition utensil, complete semen deposition.
With reference to shown in Fig. 1, in figure, 1 is anus, and 2 is vaginal orifice, and 3 is rectum, and 4 is fallopian tube, and 5 is semen deposition utensil.During concrete operations, operator tramps with one's feet the nape portion of kind duck, and kind duck is stabilized; Left hand presses a kind duck tail feathers gently, expose anus, the right hand holds the semen deposition utensil containing seminal fluid, spermatic gun head per anum doorway lower left is entered fallopian tube portio vaginalis, insert 3--5cm along vagina tube chamber, push the seminal fluid after 0.1ml dilution, or the former seminal fluid of 0.05ml, exit semen deposition utensil, namely complete the semen deposition work of a duck.Also can use liquid-transfering gun+spermatic gun head semen deposition, every duck changes a spermatic gun head.Draw the seminal fluid after 100 μ l dilutions or the intravaginal of 0.05ml former seminal fluid input duck, after exiting liquid-transfering gun, pressing liquid-transfering gun handle, remove the spermatic gun head used gently, change a new spermatic gun head, can accomplish that each duck uses a clean spermatic gun head, reduce the cross-contamination that semen deposition utensil brings to greatest extent, and can accomplish that every defeated semen dosage of duck institute is accurately consistent.Owing to only having two internal orifices in cloaca, be namely positioned at the rectum mouth of dorsal part and be positioned at the vaginal orifice of lower left side, these two interior bicker differences about 90 degree, easily distinguish; As long as 2, during semen deposition toward the vaginal orifice direction in the lower left corner, can easily find duck vagina.
Inseminated time: every morning 9 to afternoon 4 point, now few hard shelled egg in duck fallopian tube, hinders the up material of sperm to reduce.
Interval natural law: each cycle semen deposition is spaced apart 4 days.
Patent of the present invention, because turning over anus or finger probes into, just can learn and be familiar with a kind duck artificial insemination operating process, learn than turning over the shortening of anus semen deposition method and be familiar with 3 months time half a day--and half a year is not etc.; Can direct semen deposition because anus need not be turned over, duck stress be less, and employee need not again with turning over anus energetically, and operation is very easily efficient, and semen deposition speed is obviously accelerated, duck by enclose squeeze stack be subject to together stress time obviously shorten.Everyone can reach 3000 by semen deposition every day duck, raises the efficiency about 2 times; Also can normally semen deposition because not turning over the not defeated smart laying ducks of anus in the past, fertility rate of hatching egg on average improves 2.15 percentage points (referring to contrast test tables of data):
Product first week test fertility rate of egg detection table is opened in 321407 groups, field, large level ground
