Description
Technical field
The invention belongs to the feeding management fields in pig farm delivery room, and in particular to a method of improve piglet survival ratio.
Background technique
Piglet death by suffocation in birth canal is the main reason for causing the boar of high health to produce stillborn foetus.Farrowing without
Power, birth canal be narrow and the factors such as abnormal fetal position can lead to piglet and be unable to normal labor, and such as midwifery not in time will make originally living
Piglet be choked to death.The delivery interval of every piglet is about 16 minutes, with the extension of delivery interval, the ratio of stillborn foetus
It can gradually rise.In the childbirth later period, it is easy to appear the powerless phenomenon of childbirth since sow consumes a large amount of physical strength, is easy to
Generate stillborn foetus.Therefore young quantity living can be increased by carrying out midwifery in time, avoid unnecessary loss.
Maximum colostrum intake is most important to the survival of piglet in birth 24 hours, the piglet internal antibody being just born
It is horizontal very low, and have high-caliber antibody in the colostrum after giving a birth in 24 hours, blood directly can be absorbed by piglet
Liquid makes its adaptive immune power, improves the survival rate of piglet.The ability that piglet absorbs antibody in breast milk after 24 hours substantially reduces,
And the breast milk after 24 hours is also not colostrum, if newborn piglet does not obtain enough colostrums, it will lead to pig immunity
Lowly, easy infection disease and it may cause death.
Milk can be sucked after normal piglets birth, great piglet of generally coming into being occupies several pairs of creams by sow head
Head, and the small piglet of birth weight occupies several pairs of nipples by sow tail portion.When piglet number is more than sow teat number, piglet
Between can be there is a phenomenon where fighting for nipple, often the small piglet of birth weight is robbed less than nipple, is such as taken no action to, quickly will be because
It is hungry or eat less than enough colostrums and hungry to death or die of illness.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for improving piglet survival ratio, can be substantially reduced the dead of birth piglet
Tire number improves the number of live birth, while carrying out colostrum management in nursing period and entrusting one's child to the care of sb. work, and surviving for suckling pig can be improved
Rate and the uniformity improve number pigs weaned and weaning weight.
To achieve the above object, the present invention adopts the following technical scheme:
A method of improving piglet survival ratio: the time interval being born according to piglet, point for whether producing stillborn foetus and sow
Childbirth behavior is implemented rationally to deliver a child to sow；When the quantity for the piglet that is born is more than the teat number of sow, used in the colostrum phase
The method of lactation in batches is rationally entrusted one's child to the care of sb. after birth 24 hours using the method for entrusting one's child to the care of sb. that terrace work is combined with equal point-score.
It after sow starts childbirth, checks within every 20 minutes once, if producing son living, delivers a child and record upper registration practicing midwifery；Such as
Fruit produces stillborn foetus, after practicing midwifery and recording upper registration, carries out midwifery at once；Sow starts tired out after 8-10 piglet of childbirth, appropriate to increase
Add the frequency and number of midwifery；0.5 ml oxytocin is injected after childbirth, helps that afterbirth is discharged and generates colostrum.
When the piglet that is born is more than sow teat number, with delivering a child, frame is fed in batches, by brood piglet according to body
It is great it is small be divided into two parts, big being partially disposed in is delivered a child in frame, small is partially left at lactation on obstetric table, replaces per hour
1 time, repetitive operation 24 hours.

The weight for entrusting one's child to the care of sb. rear every nest piglet is close；When nest young number living is greater than sow average effective number of nipples, individual sows is allowed to feed
The piglet number educated is more than its teat number and implements to feed in batches, the piglet number and its teat number phase of the nurture of other sows
Together, and entrust one's child to the care of sb. rear every nest piglet weight it is close.All sows with delivery room terminate to repeat above-mentioned post daily before giving a birth
The process of supporting.
The sow in same delivery room all after childbirth, if nest is living young less than or equal to sow average effective number of nipples, is posted
Way before the method for supporting terminates with childbirth is identical；If nest son living is greater than sow average effective number of nipples, method is entrusted one's child to the care of sb. using the stage,
By a brood of weaned piglet in another delivery room in nursing period the 21st day, sow A is vacated, nursing period the 14th day brood will be in
Piglet, which is entrusted one's child to the care of sb., gives sow A, vacates sow B, gives sow B for entrusting one's child to the care of sb. in nursing period the 7th day a brood of piglet, vacates sow C,
The maximum a brood of piglet of age in days, which is entrusted one's child to the care of sb., in the rigid delivery room for terminating childbirth gives sow C, has just terminated remaining piglet in the delivery room of childbirth
Further according to size, the sow that is equally distributed in the delivery room.According to principle similar in brood pig weight, carry out weekly primary
Adjustment, improves the uniformity of piglet.
Frame of delivering a child selects fire proofing production, long 0.80m, wide 0.40m, high 0.30m, while accommodating 8 newborn piglets.
Remarkable advantage of the invention is: this method is according to the behavioral characteristic of sow and piglet, physilogical characteristics and growth hair
Feature is educated, complete monitoring childbirth is truly realized, guarantees that every piglet has enough colostrums, fixes each 1 piglet of nipple,
Young number and piglet survival ratio living are fundamentally improved, and further improves wean number and weaning weight.
