purpose
Standardize the operation of unified employees, further implement detailed management, and improve production performance in the delivery room.
work goals
1. Ensure that sows have good lactation performance;
2. The survival rate of weaned pigs was more than 96%, the qualified rate of weaning piglets was more than 95%, and the sow weaning rate was more than 90% on 7 days.
3. The average weaning age was 23-25 ​​days. The average weaning weight was more than 6.5 kg.
Empty bar disinfection
After the piglet is transferred out, wet the pig manure on the fence with clean water and spray it with 2% caustic soda. Then spray it with 2% caustic soda and soak for one hour. Rinse the empty bar with clean water until the bar is dry. Disinfection and deworming with disinfectant (hundred poison, etc.), then fumigation. Units with severe dermatitis or diarrhea in piglets should be flame sterilized before entering the pigs. You must finish the column at the specified time. The time for the flush is set at 1.5 days (the time of the flush time includes the day of the transfer).
Prenatal preparation
Before entering the pigs in the delivery room, first install insulation boards and light lines to prepare ready-made items such as burlap and medicine. The pigs are bathed on the day of the pigs in the delivery room, and the body can be sterilized 1-2 times before the sows are delivered. When the delivery room enters the pig, one or two pigs are placed in a ventilated area. In the summer, the insulation baffles are picked up to increase ventilation in the delivery room.
Feeding management of nursing sows
1. Feeding of sows: (Write in the sow trough for the date of production) The sows should be restricted before delivery with the maximum amount of material not higher than 3.8KG/day/head; 3 to 5 days after delivery 4—4.5kg; during the peak period of lactation (10 days after childbirth), the amount of material should reach 6.5-7KG or more, the amount of material during the peak period of breastfeeding must be maintained for 10 days, and 3 days before weaning, appropriate control should be taken. Every time the sow raises the amount of feed, it must have a 2-3 day transition, and it cannot be fed too high at a time, so as not to affect the feed intake during the peak period of the sow; sows should be free to feed during breastfeeding but should avoid Excessive leftovers cause waste (more than 90% of empty troughs after every feed), feeding 3-4 times a day, and cleaning troughs 1-2 times;
2. Sow health care: prenatal postpartum sows can add Houttuynia powder (10-20 grams), rhubarb soda powder (5-10 grams) or 1.2% baking soda to increase feed intake and prevent constipation. ;
3, during lactation on the fat or lean sows feed to be treated differently, the sows that are severely shed during lactation should be properly weaned early; try to catch sows to other units with as little as possible to catch one, two Fetal pig belt.
4. Before the weaning room, we must distinguish the sow of high gestational age from the mark of a single fetal pig so that it can be reared separately after the breeding house is vacated.
Judging childbirth
1, according to the sow due date: If the vulva inflamed, frequent urination, 1-2 days delivery;
2, shiny breasts, both sides of the breast up, all the breasts have more milk discharge, 4-12 hours delivery.
3, there is amniotic fluid broke out, can be delivered within 2 hours, the situation may be a special case of individual sows.
Note: Immediately after the symptoms of childbirth, use sterile water to disinfect the pens and sows. Requirement: One stall should correspond to one barrel (17 liter barrel) of disinfectant, and one sow should correspond to one barrel of 0.1% potassium permanganate water. The disinfectant should be ready for use. Do not put too long and Cannot be used for the next sow or the next column. Pay attention to the health corner (such as where the sow is lying and under the piglet's feed trough).
Production operation
1. Confidence management should be attended by special persons. Each time the departure time is no more than half an hour, the white shift staff must fill in the shift shift record when they leave work, and try to reduce the oral transition; the night shift staff should fill out the “Daily shift staff duty record table†by the daytime. The team leader supervises and inspects.
2. The sows should be sterilized with one-thousandth (0.1%) potassium permanganate water before delivery to sterilize the vulva, hindquarters, breasts and leg hips.
3, piglets immediately after birth with a towel or sacks to clean the mucus and nose and mouth, the pig body dry, and then cut off the umbilical cord, umbilical cord root 3-4cm off the umbilical (broken off if the umbilical to be ligation), the umbilical cord head To 5% iodine immersion in disinfection, but also to sterilize the umbilical, put the incubator 10-15 minutes to keep warm, keep the temperature inside the box 30-35 degrees, to prevent the intrusion of thieves (you can use feed bags or sacks in the incubator to engage in a Small curtain). Before the piglet feeds on the nursery bar, guess what?
4, found that the dying piglet timely rescue, first mouth mucus or amniotic fluid or amniotic fluid back out or wipe dry, you can snore brain needle 1ml, or can be artificial respiration, artificial respiration to have patience or grab the piglet's hind foot, the piglet upside down Swip the back of the hand or make the belly of the piglet face up, and use the left and right hands to flex and stretch the front and rear feet to promote the breathing of the piglets.
5, postpartum check whether the full discharge of the placenta or placental, can see whether the sow of the sow or postpartum body temperature rise (even after childbirth still fetal mole, fetal water discharge), can play oxytocin or appropriate treatment.
6, piglets before the release of colostrum, joint adhesive tape (with adhesive tape attached to the piglet joints 2/3; and tied on both sides of the production barrels so that the piglets do not damage the joints when feeding) and each The nipples squeezed out a few drops of milk. The young ones were placed on the front nipples and the big ones were placed behind. The piglets were given colostrum as soon as possible. (About 10 minutes).
Judgment and treatment of dystocia
(1) Judging dystocia: There is amniotic fluid discharge, and it is strongly held that no piglets or litter size intervals exceed 1 hour after half an hour. This is regarded as dystocia and artificial midwifery is required.
(b) The following conditions should be handled:
1, the uterine contraction weakness or birth interval is too long, can take the following methods to assist delivery:
A. Squeeze the abdomen by hand from front to back to drive the sow lying down;
B. It is helpful to give birth to a child who has a long period of calving time or a sow who has consumed too much sow;
C, injection of oxytocin 2-4ml, should pay attention to when the cervix mouth open only.
(3) If the above methods are invalid or due to oversized fetuses, improper fetal position, pelvic stenosis, etc., resulting in difficult labor, artificial midwives should be taken immediately.
1, artificial midwifery: usually flatten nails, with one-thousandth (0.1%) potassium permanganate water hand, arm, and then use paraffin oil lubrication hand, arm, and then slowly rise with the uterus contraction rhythm In the vagina, when the uterus expands, grab the piglet's lower jaw or hind legs slowly and pull it out. After the birth, the uterus should be washed and administered, and antibiotics should be injected intramuscularly for 3 days to prevent the occurrence of uterine inflammation and vaginitis. (During artificial labor, try to avoid damaging the birth canal, especially when using midwifery tools.)
2. Sows with severe damage to the birth canal should be eliminated in time. The cause of dystocia should be indicated on the card for sows with dystocia so that appropriate measures can be taken to avoid it during the next delivery.
Piglet rearing and nursing
1. Newborn piglets should be treated with 2ml of iron dextran to prevent anemia within 24 hours, and VE 0.5ml (2ml after diluted with 1.5ml saline) to prevent white muscle disease, enhance resistance, and cut teeth and tails.
2. Tooth-cutting operation: Tooth-cutting forceps should be disinfected, teeth should be cut off 2/3 (without shearing of the roots, and the fracture should be leveled), and oral amoxicillin 0.2g/head.
3, tail-clamping operation: use electric heating pliers to cut (preheat should be sufficient), leaving 1.8-2cm from the tail, the length should be consistent, and the incision should be neat, with 2-5% iodine disinfection, bleeding with severe use of permanganate Potassium powder to stop bleeding or tying with a rope (without bleeding, release the rope).
4. Fostering operation: The fostering principle of “giving the big to the small and the late to the late†is put into practice. After the piglets eat colostrum for 36 to 48 hours, they are fostered (when they are fostered, they are put on the sow’s nose or on the foster piglets. Iodine or alcohol, so that the sow can not distinguish the foster piglets, reduce the situation of the piglet being bitten by the sow or squeezing the piglets), the maximum number of sows per sow is not more than 12, and should be adjusted weekly. 3 times, to ensure piglet balance and reasonable utilization of sow's nipple, select good milk or early-born sows with weak piglet (weak young piglets usually have to strengthen nutrition nursing, such as milk powder, etc.);
5, castration operation: 3-5 days old boar castration, the incision should not be too large, do not force too much pull the testicles (or easy to cause scrotal fistula), postoperative steroids and 5% iodine sterilized, surgical blade also To disinfect, in the castration of piglets, the umbilical and injured joints of the entire pen piglet must be sterilized (2-5% iodine), the proportion of umbilical hernias should be reduced, and the piglets with joint damage should be disinfected (for joints). .
6, feeding operation: 5-7 days old piglet feed, put the material on the insulation board and chute, feed to keep fresh and clean, less feed Tim Tim, to be replaced 4 times a day. Sprinkling powder operation: grind the sucker material into powder. When the sow puts milk and the piglets are sucking, sprinkle powder on the sow's nipple, 3~4 times/day, 7 days old, continuous 7— For 10 days, the piglets have a great effect on improving feed intake after weaning.
7. Average piglet weaning at 21 to 23 days, 24 to 26 days, anti-stress VC powder 3 days before and after weaning, and 1 to 2 days after weaning, piglets should be properly restricted, and small, thin piglets can be Mix milk powder to increase feed intake or feed water.
Piglet health and immunity
(A) Piglet health:
1. Oral water-soluble amoxicillin powder 0.2g/head when cutting piglets;
2. The piglets should be given prophylactic medication 3 days before the transfer, and the dosage should be increased twice in a day. Avoid overfeeding the piglets (1 bottle/day for 3 consecutive days);
3. Add 1 to 2 needles of long-acting antibacterial agents to the piglets with severe diarrhea. The dosage is 1-2ml/head.
(b) Current immunization procedures for piglets:
1, piglet was born on the (0) day of pseudorabies nasal drops 0.5 head / head;
2, 7-day-old mycoplasma seedlings 2ml / head + blue-ear inactivated vaccine 1ml / head;
3, 14-day-old blue ear attenuated vaccine 0.3 head/head;
4, 21-day-old mycoplasma seedlings 2ml / head + blue-ear inactivated vaccine 2ml / head.
Environmental control
(a) Environmental control mainly includes:
Temperature, humidity, ammonia, dust, environmental health, etc., humidity control in the 65-75% better; ammonia taste: the human body feels uncomfortable, the pig is not comfortable, the body feels comfortable, the pig is also comfortable;
(II) Operational content of environmental control:
1. Disinfection of the pens, breasts, and vulva during the delivery of sows, and pay attention to the health situation, with special emphasis on hygiene in the middle of production, one week after birth, during the peak period of breastfeeding and several stages of weaning;
2, do a good job every day indoor and outdoor health, push one day at the end of the production column, wipe the insulation board 2 times / week, the sewer flusher to open 3 times / week, open the flusher when the record work;
3. Disinfection twice a week in the room (disinfection of glacial acetic acid for one time with body disinfection, sterilization after wet weather can be pushed forward), disinfection of the door disinfection basin and wash basin twice a week, and to ensure the effective concentration of disinfectant The pigs should be cleared away in time and the indoor garbage should be cleared once a week. The workbench should be used once a day.
4. Do not form "convection" windows (drafts) in the case of heat preservation, use fans and some thermal insulation equipment reasonably, so that large environments can be ventilated in small environments.
