Description
Technical field
The present invention relates to a kind of donkey and concentrate method of becoming pregnant.
Background technology
Stable breeding jenny ass is single due to feed mode, lacks the reason often hormone in vivo secretions such as motion unbalance, thus causes
Discharge even if folliculus ovarii grows peace and quiet, and do not oestrus performance in outside.According to incompletely statistics, the scale that cultivates at present is at 10-20
The casual household jenny ass performance rate of oestrusing of head jenny ass is general 40%-60%；And the plant jenny ass of scale oestruses, performance rate is only capable of
Reach about 20%-40%.
(1) performance rate of oestrusing is low is the main cause that donkey conception rate is low
In genesiology, the jenny ass estrus cycle is 21-24 days, and the oestrus of low altitude area, temperate zone jenny ass is generally annual 3
The middle of the month to mid-September, jenny ass can normally breed 6-7 time in the case of not becoming pregnant, and the higher Inner Mongol of elevation and latitude, new
The area such as boundary, Liaoning is only annual April to July oestrus due to the reason such as temperature is relatively low, illumination is not enough, sends out normal
Also only having 3-4 breeding chance in the case of feelings, if it occur that recessiveness is oestrused, not gestation jenny ass is only capable of breeding about 2 times every year
(casual household cultivate only jenny ass occur oestrusing sign time just contact improvement person breed), jenny ass trimester of pregnancy is longer in addition, and the foaling time is relatively
For delayed jenny ass just can not participate in breeding, so only improve oestrus conception rate can not solve these area jenny asses be subject to the end of the year
The problem that tire rate is low.
(2) synchronization of Estrus effectively reduces breeding workload
Jenny ass follicle is only needed 3-5 days by occurring to ovulate, if the jenny ass not having follicle for sounding out the people in a given scope one by one in order to break a criminal case first is long-time
Not sounding out the people in a given scope one by one in order to break a criminal case, jenny ass oestruses dispersion in addition, it is easy to cause the leakage of jenny ass to join.Scale donkey field with adaptive jenny ass 2500
As a example by, if the workload needed that is tracked every jenny ass sounding out the people in a given scope one by one in order to break a criminal case is: sounding out the people in a given scope one by one in order to break a criminal case of at least 600 jenny asses every day, work of sounding out the people in a given scope one by one in order to break a criminal case
Make the heaviest.
(3) estrus synchronization is the Research foundation of donkey embryo transfer
In recent years the embryo transfer of horse donkey, in the whole nation, a lot of units all possess some special knowledge, and embryo transfer is subject to for jenny ass and mare
Body ovulation period has higher requirement, but the synchronization of Estrus about horse and donkey relatively lags behind, domestic almost without research.
Summary of the invention
The technical problem to be solved in the present invention is the drawbacks described above how overcoming prior art, it is provided that a kind of donkey is concentrated and is subject to
Pregnant method.
For solving above-mentioned technical problem, donkey of the present invention concentrates method of becoming pregnant to comprise the steps:
One). jenny ass is concentrated and oestruses
(1). within the 1st day, choose the some heads of nonpregnant jenny ass, every jenny ass injection Cloprostenol 2-8mg；
(2). within the 2nd day, rise, RU-2267 is mixed in the middle of jenny ass daily ration by every jenny ass 8-30mg every day and feeds 7-continuously
18 days；Note: the feedstuff that jenny ass daily ration i.e. jenny ass daytime is edible.
(3). feed the last day of RU-2267, every jenny ass injection Cloprostenol 2-8mg, stop feeding four simultaneously
Alkene estrone；
Two). jenny ass concentrates artificial insemination
Stop feeding the 4-8 days of RU-2267, each jenny ass is carried out artificial insemination, and it is mono-to inject Hcg1000-6000
Position, the next day jenny ass carried out again an artificial insemination.
Hcg i.e. human chorionic gonadotropin, is a kind of glycoprotein secreted by the trophoblastic cell of Placenta Hominis, and it is by α
Glycoprotein dimeric with β forms.Human chorionic gonadotropin (HCG) α β, is synthesized by syneytiotrophoblast.Molecular weight is
The glycoprotein hormones of 36700, α subunit (promotees first shape with the FSH (follicule-stimulating hormone (FSH)) of pituitary, LH (lutropin) and TSH
Glandular hormone) etc. basic simlarity, therefore cross reaction can occur each other, and each dissmilarity of structure of β subunit.β-HCG ties in β-LH
Structure is close, but last 24 amino acid extension do not exist in β-LH.
Note: after stopping feeding RU-2267, the RU-2267 content in jenny ass body is gradually reduced, when being reduced to a certain degree
Time (about stop feed after 2-5 days in), progestogen relatively low in jenny ass body then work in coordination with estrogen Co stituation jenny ass enter
Oestrus.
Donkey and horse are all equus, and they reproductive hormone secretions are more consistent, but have bigger difference with cattle and sheep.Due to
The hormone regulating and controlling mechanism that equus is special, the hormone such as GnRH, PMSG that the animal such as cattle and sheep is usual is all the most obvious for horse donkey
Effect.Although PG2 α has preferable solute effect for the corpus luteum of donkey and horse, but medication time is the harshest, to ovulation and life
Becoming corpus luteum time shorter jenny ass not have, invalid (concrete effective time individual variation is relatively big, and general ovulation period is less than within 8 days, having
Bigger may cause injection after corpus luteum can not dissolve).
It has been investigated that injection Hcg can make jenny ass discharge the follicle (ovulation rate is more than 80%) more than 33mm in 48 hours.
Using the inventive method that the jenny ass of more than 80% can be made to concentrate in 3 days to oestrus, the jenny ass of 67% was concentrated within 5 days
Ovulation.
(1) economic benefit
Breeding jenny ass pregnancy rate improves 15%-20%
Breeding jenny ass cultivation annual return improves 450 600 yuan
3000 breeding jenny ass donkey fields increase income 500-600 ten thousand yuan
Donkey industry production value improves 56 hundred million yuan
(2) management benefit:
1. during the present invention can reduce breeding work, 80% sounds out the people in a given scope one by one in order to break a criminal case workload, solves scale donkey field because of reproduction technique personnel
The less operational difficulties brought, uses the jenny ass that expection can in a planned way be ovulated by the present invention, semen deposition two next day of being timed
Secondary, greatly reduce breeding workload, be particularly suitable for lacking the large-scale breeding donkey field of technical staff
2. synchronization of Estrus can more adapt to large-scale cultivation according to the planned production arranging donkey coltfoal of the market demand
The demand of field.
Donkey of the present invention concentrate method of becoming pregnant have easy and simple to handle, that effect is obvious, pregnancy rate is high, labor intensity is little is excellent
Point, greatly reduces and even omits jenny ass ovulation and sound out the people in a given scope one by one in order to break a criminal case work, be greatly enhanced scale and support the benefit of donkey, be suitable for extensive supporting
Donkey.
