Description
Technical field
The invention belongs to animal husbandry animal reproduction new technique application, specifically is a kind of platform for collecting sperm of alpaca with temperature controlled imitated structure of cervices.
Background technology
Alpaca originates in South America, and its main economic worth is for producing hair, every alpaca year wool production be 3-5kg, high yield alpaca year wool production can reach 10kg, the alpaca fibre quality better, and fineness, intensity and elasticity all are better than Pilus Caprae seu Ovis, human body is not had irritated the stimulation, be described as " soft gold ".Since the eighties in last century, many countries introduce alpaca, and have set up population separately in succession.In May, 2002, the Ministry of Agriculture's 948 projects " introducing a fine variety and breeding of South America alpaca " seminar of country introduces alpaca from Australia first, nearly 5 years raising is bred practice and is shown, alpaca has excellent adaptability in China central and west regions, greatly develop the alpaca aquaculture and will transfer product to China's agricultural, increasing farmers' income plays a significant role.Therefore, rapid expanding propagation, setting up China alpaca population is the important topic that development alpaca aquaculture faces.
At present, alpaca is bred in the practice both at home and abroad, mainly adopts natural mating and artificial assisting natural copulation method.The semen collection of alpaca is the key link of advanced raising technologies such as the artificial insemination of research alpaca, embryo transfer.In in the past more than 20 year, external many scholars are devoted to alpaca semen collection Study on Technology and perfect.Various semen collection methods such as condom method, electrostimulation, artificial vagina method are tested, and right semen collection difference on effect is remarkable.The semen collection of tradition domestic animal generally is made up of shell, the inner tube of a tyre and collection spermaduct with artificial vagina.The water that injects specified temp during semen collection in the inner tube of a tyre constitutes moderate pressure in certain artificial vagina.Alpaca has unique reproductive physiology character, and the one, alpaca is horizontal copulation; The 2nd, the copulation longer duration, average 20-25min, the 3rd, the alpaca penis passes cervix uteri during copulation, ejaculate at cornua uteri (Bravo PW.Reproductive endocrinology ofllamas and alpacas[M] .Veterinary Clinics of North America Food AnimalPractice WB Saunders, Philadelphia, 1994; 10:265-279.).In addition, Lichtenwalner experiments such as (1996) shows, being accompanied by the health that alternately takes place in the alpaca mating process shrinks and the urethra pulse, whenever, take turns that health shrinks and the urethra pulse is the process of once ejaculating, the about 6 times/min of pulse frequency, each copulation pulse number is 121.9 ± 61.0 (Lichtenwalner AB, Woods GL, Weber JA.Ejaculatory pattern of llamas during copulation[J] .Theriogenology1996,46:285-291.); The unique reproductive physiology character of these of alpaca is to cause the main cause of alpaca semen collection difficulty.
Summary of the invention
The present invention is in order to solve alpaca semen collection difficulty in the prior art, and the problem of existing semen collection method semen collection weak effect provides a kind of platform for collecting sperm of alpaca with temperature controlled imitated structure of cervices.
The present invention adopts following technical scheme to realize: platform for collecting sperm of alpaca with temperature controlled imitated structure of cervices, comprise the alpaca dummy teaser, and the alpaca dummy teaser is provided with the artificial vagina placing trough, and artificial vagina is installed in the artificial vagina placing trough.Described artificial vagina comprises shell, establishes in the shell and heats and temperature regulating device, establishes the water filling pressurizing valve on the shell, and the waterpower pulse device is installed on the water filling pressurizing valve valve body.The inner tube of a tyre is installed in the described shell, imitative cervix uteri structure is set in the inner tube of a tyre, imitative cervix uteri structure inlet connects the collection spermaduct.
Alpaca temperature control of the present invention is intended the associated components of uterus structure dummy by following conceptual design.
1, the design of alpaca dummy teaser.
Measure body length, neck length, the back of the body height of Different Individual ewe camel when droping to the ground, abdomen is wide, buttocks is high and the vaginal orifice height, calculating each several part meansigma methods is made the alpaca dummy teaser with wood materials, covers softish sponge and animal fur outward.
2, the design of artificial vagina.
Artificial vagina mould firmly shell built-in around heating resistance wire, inject a certain amount of water between the inner tube of a tyre and shell, place a thermocouple in the water environment, thermocouple and heating resistance wire head are wired on the digital display temperature controller, set the temperature controller temperature, energized, when inner tube of a tyre temperature is lower than design temperature, form path, heating resistance wire work is when inner tube of a tyre temperature is higher than design temperature, formation is opened circuit, heating resistance wire is not worked, and like this, reaches artificial vagina inner tube of a tyre temperature and is in temperature constant state for a long time.
Vagina shell water filling pressurizing valve place connects a waterpower pulse device, the waterpower pulse device comprises a metal shell, be equipped with piston in the housing, piston is connected to one by connecting rod and provides power by tiny engine, drive on the vibration source that the unbalanced shaft rolling disc is formed in, cause the piston motion, reach artificial vagina inner tube of a tyre pressure pulse variation effect by the waters motion.
Anatomical structure to female alpaca reproductive system discovers that there is three roads wrinkle wall at alpaca cervix uteri place, and cervix uteri the first transaction of a day's business degree is tighter than pig, but pine far away is in the cervix uteri of cattle and sheep.Discover that in conjunction with this design special " an imitative cervix uteri structure " on the artificial vagina inner tube of a tyre, " imitative cervix uteri structure " is a sunk structure, the depressed part two ends form " V " font, and recess annular placement one sponge bracket layer is with the ejaculation of simulation alpaca cornua uteri.
3, the installation and debugging of artificial vagina
Vagina shell, the inner tube of a tyre are cleaned with disinfectant solution, and the collection spermaduct is standby behind autoclaving; Connect the collection spermaduct to the inner tube of a tyre, the artificial vagina inner tube of a tyre is placed in the vagina shell, translate into shell outside the two ends; To collect spermaduct with collection spermaduct ring for fixing fixes; Inject certain water gaging to the inner tube of a tyre from the water filling pressurizing valve and cave in " Y " font; Connect thermocouple, heating resistance wire to the digital display temperature controller, set the temperature controller temperature.Opening power checks that after several minutes debugging artificial vagina inner tube of a tyre temperature, pressure are for suitable.At this moment, the artificial vagina assembly and adjustment is finished, and the artificial vagina that assembles is fixed to alpaca dummy teaser artificial vagina placing trough place.
Platform for collecting sperm of alpaca with temperature controlled imitated structure of cervices of the present invention, be exactly on the basis of domestic animal tradition artificial vagina method semen collection technology, in conjunction with alpaca reproductive physiology characteristic, horizontal posture when making up the true copulation of alpaca, make up and continue constant temperature and the intrinsic pressure environment of pulse in the artificial vagina, make up alpaca artificial vagina inner tube of a tyre cornua uteri ejaculation environment, can really simulate alpaca natural mating environment, to collect the high alpaca seminal fluid of quality.
Platform for collecting sperm of alpaca with temperature controlled imitated structure of cervices provided by the invention through the test of many times check, can be simulated alpaca natural mating true environment fully, and the collected disposable ejaculate volume of alpaca seminal fluid is many, the semen quality height.
