Description
Technical field
The invention belongs to poultry cultivating technology, particularly a kind of boar cultivation mating system.
Background technology
Along with the raising of people's living standard, the requirement of people to quality of the life is also more and more higher, especially diet aspect.Present large scale of pig farm has been a kind of trend, arises at the historic moment in piggery of all sizes, and therefore the demand of piglet is increasing, and this just proposes new requirement to boar industry.But boar industry faces the problem of two aspects at present:
1, due to the driving of market economy, the large-scale pig farm of China gets more and more, and scale is increasing, and the demand of piglet is also increasing, but neither one boar breeding at present is scientific and normal, and each boar enterprise cultivates according to the experience of oneself;
2, its habits and customs of different boars and physiological period variant, if biological control, management difficulty is larger.
Summary of the invention
The object of this invention is to provide a kind of scientific and normal, be applicable to boar and cultivate the new method of breeding.
A kind of boar cultivation mating system, the method is transformed into dispersion, random, traditional raising method concentrated, continuous, balanced continuous productive process and produces by the ecological physiology feature of pig, carries out all in all out technique, by the reproductive rhythm balanced production whole year; Described all in all out system refers to the continuous-flow type production process proceeding to a collection of swinery simultaneously, produce simultaneously, produces by reproductive rhythm, annually produces regardless of seasonal balancing.
Described all in all out, by reproductive rhythm produce key technology be estrus synchronization.The concrete grammar realizing estrus synchronization is:
(1) wean the same period method, for the childbirth nursing sow of 21 ~ 35 days, generally all can oestrus in 4 ~ 7 days after wean, implements the wean same period for the nursing sow that delivery time is close, can reach wean oestrus of sow synchronization.
(2) if sow has exceeded puberty or pregnant, pen-breeding can be carried out 2 weeks to the sow that oestruses, after 2 weeks, Cloprostenol 200 ~ 300 microgram be injected to full group, after injection hormone, pregnant sow can be miscarried simultaneously, and sow all can oestrus because of luteolysis simultaneously.
(3) sow pig not entering puberty is carried out group support by every 6 ~ 8 for a group, rule of thumb predict the time that sow pig is oestrused for the first time, before sow pig is oestrused for the first time 20 ~ 40 days, every sow shot P.G.600, oestrus and do not breed, 18th day injection Cloprostenol 200 ~ 300 microgram, after 3 days, sow just shows and oestruses, and estrus time reaches unanimity; If sow now body weight has reached breeding body weight, breeding can be arranged.
The present invention boar mating system is by for many years to the experience that the cultivation of boar draws, this method both can make the regular breeding of boar, is convenient to again produce and management, enables that work is orderly, planned to be carried out.
Embodiment
The present invention is according to experience of raising pigs for many years, and drawn cultivation and the mating system of a set of boar, the method is:
By the ecological physiology feature of pig, dispersion, random, traditional raising method are transformed into concentrated, continuous, balanced continuous productive process and produce, carry out all in all out technique, by the reproductive rhythm balanced production whole year.So-called all in all out system refers to the continuous-flow type production process proceeding to a collection of swinery simultaneously, produce simultaneously, produces by reproductive rhythm, annually produces regardless of seasonal balancing.
The raising technology index of boar is:
1, in 2.34 tires/year, 10/tire, 7 obstetric tables in the sky in advance, wean, turn group, sterilization, empty hurdle 7 days for 21 days.
2, child care to 70 age in days, seed selection to 160 age in days (22 weeks), breeding parturition rate 85%, lactation survival rate 96%, child care survival rate 98%, boar mortality 35%, artificial insemination ratio 1:80, this double ratio example 1:25.
Below with 7 days production cycles, annual 52 weeks, 2500 boars were example:
Year farrowing nest number: 2500 × 2.34=5850 nest
Farrowing nest number 5850/52=112 nest weekly
Breeding head number 112/85%=132 head weekly
Deliver weekly number pigs weaned 112*10*96%=1075 head for sale
Boar pig house is completely different from the pig house of common pork pig, and the hog house design of boar is:
Sow shifts to an earlier date 7 obstetric tables in the sky, and within 21 days, wean, turn group, sterilization, empty hurdle 7 days, need 5 weeks altogether, weekly 2 unit, every unit 56 obstetric tables, need 10 unit altogether, 560 obstetric tables.
Ensure that the boar key technology that can normally run of breeding is estrus synchronization in the present invention, can ensure that the work on pig farm is carried out in order like this, its concrete grammar is:
1, Suprapubic arch sling estrus synchronization is made
Adopt to wean method the same period: Suprapubic arch sling estrus synchronization, the most simply, the most frequently used method is the wean same period, for the childbirth nursing sow of 21 ~ 35 days, generally all can oestrus in 4 ~ 7 days after wean.The wean same period is implemented for the nursing sow that delivery time is close, wean oestrus of sow synchronization object can be reached.
2, after puberty or pregnant sow estrus synchronization
If sow has exceeded puberty, pen-breeding can be carried out 2 weeks to the sow that oestruses, after 2 weeks, Cloprostenol 200 ~ 300 microgram injected to full group.Like this after injection hormone, pregnant sow can be miscarried simultaneously, and sow all can oestrus because of luteolysis simultaneously;
3, the estrus synchronization of the sow pig of puberty is not entered
Every 6 ~ 8 sow pigs are that a group carries out group support, rule of thumb predict sow pig time of oestrusing for the first time, before sow pig is oestrused for the first time 20 ~ 40 days, every sow shot P.G.600.Oestrus and do not breed, the 18th day injection Cloprostenol 200 ~ 300 microgram, after 3 days, sow just shows and oestruses, and estrus time reaches unanimity.If sow now body weight has reached breeding body weight, breeding just can be arranged.
In the present invention, the key technology of boar estrus synchronization is: the time grasping sow puberty, if injection too early, sow does not reach the just feelings age for a long time yet after oestrusing, then no longer performance is oestrused; If injection too late, sow pig has entered oestrous cycle (namely after puberty), then sow can not oestrus because of injection gonadotropin, and estrus time would not be tending towards the same period.
The advantage of boar mating system of the present invention is:
One, can reduce the head number of sow to be joined and replacement gilt, because be 21 days the oestrus of pig, be the multiple of 7;
Two, the technical work of breeding and work task can be arranged in one week 5 days and complete, avoid Saturday or Sunday, because most of sow oestruses afterwards in wean (wean on Thursday) for 4th ~ 6 days, breeding work can be arranged in three days and complete, as arranged breeding from Monday to Thursday, the number of deficiency can be supplemented by replacement gilt by regulation requirement, can make the breeding of production like this and turn group to work and all completed before Thursday.
Three, be conducive to by week, monthly and per year work out work plan, set up orderly work and holiday system, reduce confusion and the blindness of work.
