Description
Technical field
The present invention relates to animal-breeding technical field, more particularly to a kind of promote optimized varieties and improve the kind sheep of reproductive capacity
Breeding and reproduction technique.
Background technology
Anhui White Goats belong to meat and fur sheep, and in warm temperate zone half, gentle weather conditions are formed by long-term breeding
Local varieties, are distributed between Anhui Province's North-Anhui district and Yangze river and Huai river northern, and the kind is so that sex premature, reproductive capacity is high, slab quality
It is good and famous, but its individuality is small, the speed of growth is slow, and it is mutton sheep production to pretend.Anhui White Goats 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 administrative skill not
In place and feeding process lacks reasonability, cause Anhui White Goats fertility not strong, farrowing is few, farrows weak, the culture-cycle
Long the problems such as, the economic benefit of sheep cultivation is had a strong impact on, hindered the further development of sheep aquaculture.
The content of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of kind sheep for promoting optimized varieties and improving reproductive capacity
Breeding and reproduction technique.
The present invention is achieved by the following technical solutions：
It is a kind of to promote optimized varieties and improve the breeding of kind sheep and the reproduction technique of reproductive capacity, including the following aspects：
（1）Bred when selecting：Anhui White Goats reach sexal maturity for general 5-8 after birth month, and sexually matured ram performance is tail
With and mounting ewe, ewe then show as anorexia, it is excited uneasy, whinny, other sheep of mounting or receive other sheep mountings and
It is quiet vertical motionless, again and again urination and flow out transparent liquid, contacted with ewe with examination feelings ram, ewe performance docility, and by rear quarters
Turn to ram；Typically 10 more than the monthly age, ram carries out just matching somebody with somebody ewe in or so August age, and ewe estrus duration is generally
40 hours, breeding in 12-24 hours was most appropriate after heat；If ewe heat is not obvious, accurate estrus time is not observed,
Feelings can be tried with ram, ewe does not refuse ram can be considered suitable to breeding；September, October are the golden seasons of sheep breeding, now female
Sheep heat is generally vigorous, ram hypersexuality, and along with weather is nice and cool, benign climate, forage grass resource enriches, can be in next year after breeding
2 months, March lambing, now weather turn warm, plant recovery is extremely advantageous to growing for lamb；
（2）Reinforcing is raised：To strengthen kind of a feeding and management for male and female sheep within 1-2 month before the breeding busy season arrives, stud ram exists daily
Receipts mend 400-600 grams of mixed concentrate of feeding after herding, Concentrate formula composition is as follows：Corn protein powder 240-280, fermented bean dregs 250-
270th, expanded wheat bran 30-50, tomato puree 50-60, Silkworm pupa protein 40-50, Chinese cabbage leaf powder 35-45, lavender powder 5-6, chicken bone
Oily 5-6, pearl white 4-5, salt 1-2；When semen collection is frequent, feeding amount and feeding number of times should be increased, and ensure that stud ram has weekly
The time of having a rest of 1-2 days, so as not to because consume excessively nutrient and muscle power and caused by body condition be decreased obviously；Plant ewe daily after receipts are herded
200-300 grams of supplementary feeding mixed concentrate, mixed concentrate formula is as follows：Fermented bean dregs 230-250, corn plumule powder 140-160, molasses
10-15, roasted sesame 14-15, lily root flour 8-10, carrot juice 40-50, beet tops powder 30-40, Ligusticum wallichii 0.5-1, barrenwort 1-2,
Radix scrophulariae 1-2, salt 1-2, egg 2-3, soybean lecithin 2-3；
（3）Strengthen motion：Keep kind of sheep has the motion of abundance daily, to promote its metabolism, keeps physique healthy and strong, stud ram
Off-breeding season daily amount of exercise is not less than 4h, and mating season can suitably reduce, and ewe should also be as strengthening motion before breeding, with
Ensure that body condition is good, sheep hurdle will keep connecting with sports ground, be easy to sheep freely to come in and go out the activity of carrying out；
（4）Carry out expelling parasite：It is the end of summer, just turning into autumn is the season occurred frequently of parasitic disease, before breeding, uses tetramisole, tetramisole, rosickyite
The anthelmintic drugs such as imidazoles, AVM carry out expelling parasite to kind of goat, improve the resistance of sheep itself, ready to breed, and one
As pointedly select anthelmintic drug, cross-reference 2-3 kinds anthelmintic or reuse 2 and inferior can all obtain preferable expelling parasite effect
Really；
（5）Artificial insemination：Artificial insemination is that method manually produces the seminal fluid of ram, again to the ewe of heat after treatment
Semen deposition, makes it be impregnated, and artificial insemination can expand the value of excellent ram, improves the conception rate of ewe, effectively reduces disease
The infection of disease；Semen collection, insemination operating room requirement Land leveling, bright and clear, spacious, cleaning, room temperature maintain 18 DEG C -25 DEG C,
Daily sterilization carries out spray disinfectant with 1% liquor potassic permanganate, daily in being carried out before semen collection and respectively 1 time after semen collection；Artificial insemination institute
With apparatus, need to by fully scrubbing, strict sterilization, in case infecting；The age of stud ram first time semen collection should be left in 1.5 one full year of life
The right side, the growth of livestock is medium, the first ram for participating in semen collection, should first carry out semen collection training, and method is to allow it " to view and emulate " other rams to breed,
Or excited sexual desires with heat ewe, after semen collection instruction is trained successfully, can just carry out formal semen collection；The adult daily semen collection of stud ram
2-3 times, rest 1-2 days weekly, just adopting sheep can cut down according to the circumstance；The seminal fluid for collecting will in time be sent to process chamber, carry out semen quality inspection
Look into, qualified ram seminal fluid is creamy white, naked eyes it can be seen that milky cloud, tasteless or slightly fishy smell, and sperm motility exists
More than 60%, more than medium, abnormal sperm rate is no more than 20% to density；It is all with putrefactive odor through visual examination, occur red
Color, brown, the seminal fluid of green are judged to seminal fluid inferior, should discard without generally no longer doing microexamination；Ram is each
Ejaculation amount is 0.5-2ml, can dilute 2-3 times, and every ewe semen deposition 0.1-0.2ml a, semen collection can match somebody with somebody ewe 30, and one is matched somebody with somebody
Ewe 800 can be matched somebody with somebody in kind of phase, than this friendships can more than 10 times of polygamy, greatly save ram and raise required production cost；1
To ewe semen deposition 2 times, semen deposition 1 time at the beginning of heat is spaced semen deposition 1 time again, every ewe after 8-10 hour to individual oestrus planted agent
Insemination dose is for original seminal fluid 0.05-0.10ml or dilutes seminal fluid 0.1-0.2ml；During to heat ewe semen deposition, reply external genital enters
Row cleaning, it is to be dried after wiped with physiological saline cotton balls again, spermatic gun should be slowly inserted into essence in cervix at 0.5-1.0cm
Liquid slowly injects, and after semen deposition is finished, allows sheep to keep former posture for a moment, decontrols ewe, is released again after original place standing 5-10min；
