Abstract
The invention discloses a method for increasing a survival rate of piglets, wherein rational delivery is implemented to female pigs according to time intervals of birth of the piglets, whether stillbirth takes place and delivery behaviors of the female pigs; when the quantity of the born piglets exceeds an effective quantity of nipples of the female pig, in-batch lactation is carried out during a colostrum period, and rational fostering is carried out through a fostering method combining a stage method and an equalization method 24 hours later since the birth. According to the method, the stillbirth quantity of the born piglets can be obviously reduced and the number of live births can be increased. Meanwhile, management in the colostrum period and the fostering work are carried out during a lactation period, so that the survival rate and a uniformity degree during lactation of the piglets can be increased, and the quantity of the weaned piglets and weaning weights can be increased.
Description
Technical field
The invention belongs to the feeding and management field in delivery room, pig farm, be specifically related to a kind of method improving piglet survival ratio.
Background technology
Piglet death by suffocation in birth canal is the main cause causing the boar of high health to produce stillborn foetus.Farrowing is unable, birth canal is narrow and the factor such as abnormal fetal position all can cause piglet can not normal labor, as practise midwifery not in time, is choked to death making the piglet originally lived.The parturition interval of every piglet is about 16 minutes, and along with the prolongation of parturition interval, the ratio of stillborn foetus also can raise gradually.In the childbirth later stage, easily there is unable phenomenon of giving a birth because sow consumes a large amount of muscle power, as easy as rolling off a log generation stillborn foetus.Therefore carry out practise midwifery in time and can increase young quantity of living, avoid unnecessary loss.
The survival of colostrum intake to piglet maximum in 24 hours of being born is most important, the piglet internal antibody level of firm birth is very low, and the first Ruzhong in point 24 hours puerperiums possesses high-caliber antibody, directly can be absorbed by piglet and enter blood, make its adaptive immune power, improve the survival rate of piglet.After 24 hours, piglet absorbs the ability of antibody in breast milk and greatly reduces, and breast milk after 24 hours neither colostrum, if newborn piglet does not obtain enough colostrums, will cause pig hypoimmunity, easy infection disease also may cause death.
Namely can suck milk after normal piglets birth, it is several to nipple that general nascent great piglet occupies by sow head, and that the little piglet of birth weight occupies by sow afterbody is several to nipple.When piglet number exceedes sow teat number, can fight for the phenomenon of nipple between piglet, the piglet that often birth weight is little is robbed less than nipple, if do not taken measures, very fast just can because of hungry or eat and to die of hunger less than enough colostrums or die of illness.
Summary of the invention
The object of the present invention is to provide a kind of method improving piglet survival ratio, obviously can reduce the stillborn foetus number of birth piglet, improve the number of live birth, carry out colostrum management in lactation simultaneously and entrust one's child to the care of sb. work, survival rate and the uniformity of suckling pig can be improved, improve number pigs weaned and weaning weight.
For achieving the above object, the present invention adopts following technical scheme:
A kind of method improving piglet survival ratio: implement rationally to deliver a child to sow according to the time interval of piglet birth, the Parturition behavior that whether produces stillborn foetus and sow; When the quantity of the piglet that is born exceedes the teat number of sow, adopt the method for lactation in batches in the colostrum phase, the method for entrusting one's child to the care of sb. adopting terrace work to combine with equal point-score after 24 hours of being born rationally is entrusted one's child to the care of sb..
Sow starts a point puerperium, within every 20 minutes, checks once, lives young, to deliver a child and in registration on record of practicing midwifery if produced; If product stillborn foetus, practicing midwifery on record after registration, carry out practise midwifery at once; Sow after 8-10 piglet of giving a birth starts tired out, suitably increases frequency and the number of times of practise midwifery; Childbirth terminates rear injection 0.5ml oxytocin, contributes to discharging afterbirth and producing colostrum.
When the piglet that is born is more than sow teat number, with delivering a child, frame is fed in batches, and brood piglet is divided into two parts according to body weight size, large part being placed in delivers a child in frame, little part stays lactation on obstetric table, alternately 1 time per hour, repeats 24 hours.
Before the sow in same delivery room is all given a birth and terminates, piglet more than 1 age in days in same delivery room is entrusted one's child to the care of sb., when nest young number all alive is less than or equal to sow average effective number of nipples, from the nest of brood piglet number more than sow teat number, send some piglets be less than in the nest of sow teat number to brood piglet number, make the piglet number of every sow band roughly equal and to entrust one's child to the care of sb. the body weight of rear every nest piglet close; When nest young number all alive is greater than sow average effective number of nipples, the piglet number allowing indivedual sow to feed exceedes its teat number and implements to feed in batches, the piglet number of other sows nurture is identical with its teat number, and the body weight of entrusting one's child to the care of sb. rear every nest piglet is close.All sows with delivery room are terminated to give a birth and repeat front every day above-mentioned to entrust one's child to the care of sb. process.
After the sow in same delivery room is all given a birth and terminates, if nest is all lived, son is less than or equal to sow average effective number of nipples, and the way before method of entrusting one's child to the care of sb. terminates with childbirth is identical; If nest is all lived, son is greater than sow average effective number of nipples, the employing stage entrusts one's child to the care of sb. method, the a brood of weaned piglet in another delivery room of the 21st day lactation will be in, vacate sow A, the a brood of piglet being in the 14th day lactation is entrusted one's child to the care of sb. to sow A, vacate sow B, the a brood of piglet being in the 7th day lactation is entrusted one's child to the care of sb. to sow B, vacate sow C, a brood of piglet maximum for age in days in the delivery room just terminating to give a birth is entrusted one's child to the care of sb. to sow C, just terminate piglet remaining in the delivery room of giving a birth again according to size, distribute to the sow in this delivery room equably.The principle close according to brood pig weight, once adjusts weekly, improves the uniformity of piglet.
Frame of delivering a child selects fire proofing to make, and long 0.80m, wide 0.40m, high 0.30m hold 8 newborn piglets simultaneously.
Remarkable advantage of the present invention is: the method is according to the behavioral characteristic of sow and piglet, physilogical characteristics and growth and development characteristics, really accomplish that complete monitoring is given a birth, ensure that every piglet has abundant colostrum, fixing each nipple 1 piglet, fundamentally improve live young number and piglet survival ratio, and further increase wean number and weaning weight.
