Description
Technical field
The present invention relates to animal cultivation technical field, particularly relate to a kind of Anhui White Goats kind sheep fast-propagation technology.
Background technology
Anhui White Goats belongs to meat and fur sheep, and in warm temperate zone half, gentle weather conditions are formed through long-term breeding
Local varieties, are distributed between Anhui Province's North-Anhui district and Yangze river and Huai river the north, and this kind is with sexual precosity, reproductive capacity height, slab quality
Well famous, but its individuality is little, the speed of growth slow, pretends and produces into meat sheep.Anhui White Goats body constitution is solid, and structure is well-balanced, meat
Matter is delicious, hide quality is good, breeding potential is high, is excellent local herding kind.Under traditional cultivation, due to management technique not
Putting in place and feeding process lacks reasonability, cause Anhui White Goats fertility not strong, farrowing is few, farrows weak, the culture-cycle
The problems such as length, have had a strong impact on the economic benefit of sheep cultivation, hinder the further development of sheep aquaculture.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of Anhui White Goats kind sheep fast-propagation technology.
The present invention is achieved by the following technical solutions:
A kind of Anhui White Goats kind sheep fast-propagation technology, including the following aspects:
(1) seed selection of male and female sheep is planted
A, stud ram should select production performance good, and ripe early reproductive capacity is high, and heritability is strong, healthy, solid, profile, body constitution
Zero defect, genital organ growth is normal, has obvious varietal characteristic, and the ram that semen quality is good makees kind of a sheep；The choosing that ram is individual
Select and should follow following four aspect: 1. according to individual Phenotypic Selection, 2. select according to the pedigree of ancestors, 3. survey according to half sib
Test achievement to select, 4. select according to offspring's quality；
B, planting ewe and should select energetic, growth promoter is good, hair color light, moist, healthy and strong, do not have disease, skin
Soft high resilience, enlarged abdomen and the most sagging, rear quarters width is deep, the high-quality ewe that production performance is good；
(2) plant at the beginning of male and female sheep and join age and service life
Joining age and service life at the beginning of a, stud ram: the first mating age of stud ram is the 10-12 monthly age, the stud ram that grows up is adopted every day
Essence 2-3 time, rest 1-2 days weekly, first seed collecting ram can be cut down according to the circumstance；Stud ram service life is 4-6 under normal circumstances, has following
One of situation need eliminate: due to illness, due to wound can not user, semen quality failure, the joined low person of ewe conception rate；
Age and service life is joined: the outer kind of standby ewe just joined selected at the 9-10 monthly age, second or third time at the beginning of b, kind ewe
After oestrusing or body weight reaches the ewe of more than double centner, if the just timing of the hybrid ewe containing local goats blood relationship then can carry
Front January；The service life of ewe is 4 years under normal circumstances, has one of situations below to need to eliminate: major injuries, due to illness can not
Being used as to plant, continuous 2-3 tire reproductive capacity is low, has the out-of-the-way person of serious evil；
(3) preparation before breeding
A, ram instruction: the standby ram 7-8 monthly age can start instruction, has the ram of breeding experience also can carry out semen collection instruction, side
Method is that the seminal fluid of adult ram, foreskin secretions or ewe urine of oestrusing are coated in false platform sheep rear portion, and ram causes false platform
Sheep trains its mounting, can look after and guide every day 1 time, but the time of every time looking after and guiding was preferably no more than 15 minutes；
B, ram examination feelings: examination feelings ram to select healthy and strong, be highly sexed, there is no the preferable stud ram of disease production performance,
Examination feelings ram task be find and find out oestrus ewe with facilitate in the future breeding be used, examination feelings time examination feelings ram with clone
Examination feelings cloth, respectively puts into the ram with examination feelings cloth and carry out in ewe group trying feelings every day, and the time is about one hour, right
The ewe that oestruses tried out should breed in time according to matching principle and perform registration；
C, ewe symptom of estrus are observed: morning every day, evening carry out a symptom of estrus respectively and observe ewe, and the project of observation is main
Have the following aspects: 1. behavior: ewe oestrus beginning time show as uneasiness, appetite declines, to oestrus the Sheng phase time, like mounting
Other ewes or accept other ewe mountings, automatically close to ram, are ready to accept mounting and copulation during by ram examination feelings；2. outside
Cloudy: ewe proestrus group pudendum starts redness, and color from light to dark, and flows out a small amount of hyalomucoid, Sheng of oestrusing phase pudendum flows out
The white thread mucus of thick band；3. back reflection is pressed: firmly pressing ewe waist plants oneself, and lifts tail prick ear, shows copulation appearance
Gesture is i.e. " quiet vertical reflection "；
(4) breeding breeding
A, optimize breeding scheme: planting sheep apolegamy one is according to individual grade apolegamy, principle be with excellent join excellent, with in excellent joining, with in
In joining, with in join difference, ram grade should be higher than that ewe, never allows the ram copulation that the high ewe of grade is low with grade；Two are
Matching according to the age, male young sheep and adult ewe copulation, grow up ram and young ewe copulation, grow up ram and adult ewe
Copulation, grow up ram and aged ewe copulation, do not allow young and young, old and old copulation；
B, reasonable breeding time: ewe breeding time was for after beginning of oestrusing 24-36 hour, and specific features is when observing ewe
Vaginal orifice by congested red and swollen to disappear purplish red dimness, swelling and occur wrinkle, mucus by thin to thick and with thread, go out
Breeding can be started time existing " quiet vertical reflection "；
C, breeding wony and number of times: in the case of stud ram lacks or implements selection-breeding plan, the breeding wony of goat should use
Technology of artificial insemination, generally has only to this and hands over；Just joining ewe and use this copulation kind 3 times, multiparity ewe uses people
Work insemination semen deposition 2 times, first service (semen deposition) is spaced afterwards 8-12 hour and carries out 2,3 breedings (semen deposition) again；
(5) cyesiognosis
A, employing external observation method: after ewe gestation, normally behave as periodically oestrusing stopping, and disposition is docile, quiet, and behavior is careful
Careful, meanwhile, Thyroid Activity gradually strengthens, honey stomach, and feed intake increases, and nutriture improves, and hair color is bright, moist, arrives
Gestation latter half (after 3-4 month) abdominal circumference increases, and on the right side of stomach wall, (pregnant side) is the most sagging more prominent than left side, rib abdominal retraction, breast
Room increases；The disadvantage of external observation method be can not in early days (before and after rear first feelings phase of breeding) make a definite diagnosis whether gestation, and
There is no during a certain or certain several performance just certainly can not there is no gestation, some observation item that can make a definite diagnosis typically all is existed
Gestation middle and late stage could be it is evident that this be it is possible to affect the rutting again of ewe；When carrying out external observation, it should be noted that
Be breeding after oestrus again, such as minority sheep (about 30%) has false heat to show after gestation, makes nonpregnant conclusion according to this not
Correctly, but there is no gestation after breeding, and due to genitals or other diseases and feeding and management is improper and non-estrus person, accordingly
The conclusion making gestation is also wrong；
B, use stomach wall Palpation: ewe should stop to raise at palpation previous evening, clamps the cervical region of sheep or front body Baoding with both legs, double
Stomach wall under hand-tight patch, touches with or without lump with the abdominal part slide anteroposterior on left hand stomach wall or two pairs of breast tops under right side, permissible
Palpation, to fetus, can touch cotyledon sometimes, when fetus thoracic wall is close to ewe stomach wall auscultation, can hear fetal heart sound, root
May determine that ewe is the most pregnant according to these；The most accurate method is that palpation combines examination per rectum, and its concrete grammar is: allow
Stop raising the ewe to be checked at a night to lie on the back Baoding, with soapsuds enema, to discharge the place excrement in rectum, then will scribble lubricant
The smooth wooden stick of (such as suds, edible oil etc.) or sticking plaster (diameter 1.5 centimetres, long 50 centimetres, front short thinner and blunt) insert
Anus, presses close to spinal column, slowly inserts 30 cm to internal rectum, and then, the other end of pressure palpation rod, makes internal rectum down
One end is provoked slightly, and another hands stomach wall on the right side of ewe touches simultaneously, if touching block entity then for gestation；This method checks
Breed 60 days later ewes, and accuracy rate about 95%, within 85 days, later accuracy rate is up to 100%；When it should be noted that inspection
Action is light and slow, and to prevent damage rectal, the 115 days later ewes that breed should not use this method to check；
C, use examination per vagina method: the color and luster of pregnancy ewes vaginal mucosa, mucus character and cervical orifice shape all have some and
The rule change that gestation is consistent, the method utilizes vagina prolapsus appliance (speculum) to open vagina, according to intravaginal mucosa exactly
Color and mucus situation judge that ewe is the most pregnant；1., after ewe pregnancy, vaginal mucosa is by rose pink complexion changed time nonpregnant
For pale asphyxia, but after opening vagina with prolapsus appliance, i.e. being become again pink in several seconds by pale asphyxia, nonpregnant ewe mucosa is all the time
For pink；The transparent shape of vaginal mucus of the most pregnant sheep, and measure seldom, the most dense thick, line can be led between finger；Phase
Instead, if mucus amount is many, thin, mobility is strong, can not lead into line between referring to, color is greyish white, ewe in pus shape is unpregnancy；
The most pregnant sheep cervix uteri closes, and color and luster is pale, and has starchy grume to be blocked in cervical orifice, and people are referred to as " uterus bolt ",
It should be noted that the arm etc. at the provagina prolapsus appliance and inspection personnel that do examination per vagina conscientiously to be sterilized；
(6) breeding management system
A, breeding room often keep clean and tidy, and all apparatuses should carry out strict cleaning and sterilizing the most afterwards, place fixing place；Room
Interior absolutely no smoking, forbids to place poisonous, harmful, inflammable articles and any article unrelated with breeding；
B, mating technology personnel should grasp oestrus rule and the Pregnancy of flock of sheep in detail, and application seminal fluid quantity etc. to have perfect
Record, and make analysis at any time, sum up, set up monthly magazine system；
C, the rutting implementation poultry raiser to ewe, person on duty, breeding person three combine, and conscientiously observe, find in time, join in good time
Kind；In strict accordance with apolegamy plan, it is ensured that do not leak and join, disorderly join and mispairing；Ewe should breed in 2 months and become pregnant puerperal, each feelings
Phase semen deposition or natural mating 1-2 time, unpregnancy of more than all 3 feelings phases breeding does not has, and should do special handling, use corresponding measure；
D, set up breeding archives, improve breeding record, conscientiously carry out the oestrusing of individual sheep, semen deposition and Pregnancy record, and make
The fixed dry breast governing plan such as time and expected date of confinement.
Beneficial effects of the present invention:
The present invention, according to the distinctive physiology of Anhui White Goats and growth characteristics science selection-breeding, can be greatly improved the numerous of Anhui White Goats
Growing ability, improve farrowing rate, increase nest litter size, increase lamb birth weight and lamb survival rate, the inventive method is reasonable, management
Proper, the scientific raising of peasant household can be instructed, it is ensured that scale sheep raising is developed in a healthy way, improve the section content of sheep raising, promote that scale is supported

Technology of artificial insemination, generally has only to this and hands over；Just joining ewe and use this copulation kind 3 times, multiparity ewe uses people
Work insemination semen deposition 2 times, first service (semen deposition) is spaced afterwards 8-12 hour and carries out 2,3 breedings (semen deposition) again；
(5) cyesiognosis
A, employing external observation method: after ewe gestation, normally behave as periodically oestrusing stopping, and disposition is docile, quiet, and behavior is careful
Careful, meanwhile, Thyroid Activity gradually strengthens, honey stomach, and feed intake increases, and nutriture improves, and hair color is bright, moist, arrives
Gestation latter half (after 3-4 month) abdominal circumference increases, and on the right side of stomach wall, (pregnant side) is the most sagging more prominent than left side, rib abdominal retraction, breast
Room increases；The disadvantage of external observation method be can not in early days (before and after rear first feelings phase of breeding) make a definite diagnosis whether gestation, and
There is no during a certain or certain several performance just certainly can not there is no gestation, some observation item that can make a definite diagnosis typically all is existed
Gestation middle and late stage could be it is evident that this be it is possible to affect the rutting again of ewe；When carrying out external observation, it should be noted that
Be breeding after oestrus again, such as minority sheep (about 30%) has false heat to show after gestation, makes nonpregnant conclusion according to this not
Correctly, but there is no gestation after breeding, and due to genitals or other diseases and feeding and management is improper and non-estrus person, accordingly
The conclusion making gestation is also wrong；
B, use stomach wall Palpation: ewe should stop to raise at palpation previous evening, clamps the cervical region of sheep or front body Baoding with both legs, double
Stomach wall under hand-tight patch, touches with or without lump with the abdominal part slide anteroposterior on left hand stomach wall or two pairs of breast tops under right side, permissible
Palpation, to fetus, can touch cotyledon sometimes, when fetus thoracic wall is close to ewe stomach wall auscultation, can hear fetal heart sound, root
May determine that ewe is the most pregnant according to these；The most accurate method is that palpation combines examination per rectum, and its concrete grammar is: allow
Stop raising the ewe to be checked at a night to lie on the back Baoding, with soapsuds enema, to discharge the place excrement in rectum, then will scribble lubricant
The smooth wooden stick of (such as suds, edible oil etc.) or sticking plaster (diameter 1.5 centimetres, long 50 centimetres, front short thinner and blunt) insert
Anus, presses close to spinal column, slowly inserts 30 cm to internal rectum, and then, the other end of pressure palpation rod, makes internal rectum down
One end is provoked slightly, and another hands stomach wall on the right side of ewe touches simultaneously, if touching block entity then for gestation；This method checks
Breed 60 days later ewes, and accuracy rate about 95%, within 85 days, later accuracy rate is up to 100%；When it should be noted that inspection
Action is light and slow, and to prevent damage rectal, the 115 days later ewes that breed should not use this method to check；
C, use examination per vagina method: the color and luster of pregnancy ewes vaginal mucosa, mucus character and cervical orifice shape all have some and
The rule change that gestation is consistent, the method utilizes vagina prolapsus appliance (speculum) to open vagina, according to intravaginal mucosa exactly
Color and mucus situation judge that ewe is the most pregnant；1., after ewe pregnancy, vaginal mucosa is by rose pink complexion changed time nonpregnant
For pale asphyxia, but after opening vagina with prolapsus appliance, i.e. being become again pink in several seconds by pale asphyxia, nonpregnant ewe mucosa is all the time
For pink；The transparent shape of vaginal mucus of the most pregnant sheep, and measure seldom, the most dense thick, line can be led between finger；Phase
Instead, if mucus amount is many, thin, mobility is strong, can not lead into line between referring to, color is greyish white, ewe in pus shape is unpregnancy；
The most pregnant sheep cervix uteri closes, and color and luster is pale, and has starchy grume to be blocked in cervical orifice, and people are referred to as " uterus bolt ",
It should be noted that the arm etc. at the provagina prolapsus appliance and inspection personnel that do examination per vagina conscientiously to be sterilized；
(6) breeding management system
A, breeding room often keep clean and tidy, and all apparatuses should carry out strict cleaning and sterilizing the most afterwards, place fixing place；Room
Interior absolutely no smoking, forbids to place poisonous, harmful, inflammable articles and any article unrelated with breeding；
B, mating technology personnel should grasp oestrus rule and the Pregnancy of flock of sheep in detail, and application seminal fluid quantity etc. to have perfect
Record, and make analysis at any time, sum up, set up monthly magazine system；
C, the rutting implementation poultry raiser to ewe, person on duty, breeding person three combine, and conscientiously observe, find in time, join in good time
Kind；In strict accordance with apolegamy plan, it is ensured that do not leak and join, disorderly join and mispairing；Ewe should breed in 2 months and become pregnant puerperal, each feelings
Phase semen deposition or natural mating 1-2 time, unpregnancy of more than all 3 feelings phases breeding does not has, and should do special handling, use corresponding measure；
D, set up breeding archives, improve breeding record, conscientiously carry out the oestrusing of individual sheep, semen deposition and Pregnancy record, and make
The fixed dry breast governing plan such as time and expected date of confinement.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
