Management of parturient sows

Effective delivery house management is the key to the success of pig farms. Because the biggest loss of pigs in a pig farm is likely to be in the delivery house or nursery, the quality of the piglets raised in the nursery depends to a large extent on the quality of the weaned piglets provided by the delivery house. The delivery house is of the highest grade of equipment and the best personnel. The efficiency of the delivery house depends on the situation of the sow and the joint efforts of the administrator and the breeder. The purpose of this stage is to improve the survival rate, weaning litter number and litter weight of piglets, maintain the physical condition of sows and improve the service life of sows. First, prenatal work 1, thoroughly rinse the pigsty, thoroughly disinfect and dry. 2. Check the condition of each facility and repair the damage in time. 3. Wash away the dirt of the pig, especially where the hindquarters, breasts, hooves and legs come into contact. After washing, disinfect with diluted iodine tincture or other disinfectants. 4. The washed sows will be rushed to the birth bed 5 days ahead of time to adapt to the new environment. Drive pigs patiently, not rudely, and beware of sow injuries and miscarriages. 5. Sows are observed to pick up the sows during each feeding, and to observe their feeding conditions. Any abnormal situation may indicate that they are about to give birth or stress. ① examines sow faeces to avoid constipation, as constipation can lead to birth difficulties and affect lactation. If constipation occurs, sodium sulfate laxative can be added to the material. ② installed heat preservation lamp to keep the birth column clean, and immediately clear the production column when there is feces. 2. Delivery operation 1. After the parturient sows arrive at the delivery bed, they should pay attention to observation every day. 24 hours before delivery, the sows are generally restless, frequent urination, defecation, reduced food or do not eat often turn over, nipples can squeeze out milk, when the last pair of nipples can squeeze out milk, about 6 hours delivery, and at this time breathing accelerated to 90 times per minute, when reduced to 70 times to begin delivery. Fluid from the vulva-breaking water in labor. 2. Prepare tooth scissors, ear pliers, thread, injection syringe, necessary medicine (oxytocin, iodine tincture, etc.), thermal lamp, clean towels, sacks and other items for delivery. 3. After the delivery of the piglets, the mouth, nose, fetal water and membrane should be wiped clean with a towel. Cut off the umbilical cord, apply iodine tincture, cut off 8 deciduous teeth (pay attention to flat scissors, cut teeth, in case uneven teeth hurt sows' breasts), put them in an incubator covered with sacks, and take them to the nipples of sows to help them suck when they regain their strength. If a fake dead pig is found (there is a slight beat at the base of the umbilical cord), it should be rescued immediately. 4. after eating colostrum, inject iron, cut off the tail, cut the ear number, and apply iodine tincture to the wound. 5. If the next piglet is not excreted after a long interval, oxytocin should be injected intramuscularly. After the note, if the responsibility is frequent, but can not be lined up for a long time, artificial midwifery will be considered. Before midwifery, you should cut your nails, wash and disinfect your arms. Fingers together, slowly reached in and pulled out the pig. Note: 1. Piglets should squeeze out a few drops of milk from sows' nipples before eating. 2. The blood polypeptide is injected into the medial side of the neck and the needle is inserted into the muscle for injection. Tighten the skin when entering the needle, and loosen it after injection to prevent the backflow of iron. 3. You can take a few shots of the fake dead pig, squeeze the umbilical cord blood to the abdomen regularly, and do artificial respiration. The most important thing in the rescue work is persistence, and it should not be stopped unless it is confirmed that it is dead. 4. The umbilical cord should leave 3-4cm to tie the applied thread that still bleeds after severing. 5. Don't hurt your gums when cutting your teeth. 6. In order to prevent the occurrence of tail biting accident, the cm should be cut from the root of the tail. The boar is the upper margin of the scrotum and the sow is the broken tail of the superior margin of the vagina. 7. At birth, the temperature under the incubator lamp should be controlled between 33 and 35 degrees. In this way, the piglets can be dried quickly and regain their strength. 8. Sows were injected with penicillin and streptomycin within 8 hours after delivery. If there is inflammation, add three days and add dexamethasone. If not, the uterine cavity should be irrigated. 9. Sows should be kept quiet as far as possible so as not to interrupt the delivery of sows. Nursing care of suckling pigs 1. Newborn suckling pigs are very sensitive to external temperature changes, their own thermoregulation function is not complete, less subcutaneous fat, and more heat dissipation, so it is most important to maintain a certain environmental temperature. The lowest temperature of the incubator should be 33 ℃ at birth, and then it can be reduced by 1-2 ℃ per week. 2. Although suckling pigs can obtain a large number of antibodies from colostrum secreted by sows, their resistance to pathogenic microorganisms is still very weak, so it is important to keep the birth bed clean. 3. Suckling pigs get the nutrition of their own development from breast milk, so it is necessary to ensure the full supply of quality and quantity of breast milk. 4. The action and anti-stress ability of suckling pigs within one week of birth is very weak, so we should pay attention to the following questions: whether ① is trampled by sows or pressed when sows lie down. Whether ② sows can get breast milk in time, those who are out of group should be put back to the side of breast milk. ③ fixed the nipple so that the little suckling pig ate the front nipple. ④ carried back to the incubator for suckling pigs that could not find the incubator. 5. Foster care, such as too much or too little litter in the sow, no milk, less milk, poor milk quality or postpartum disease in the sow, and when the piglets are too small to keep up with the weight of the same litter. The parturition period of ① piglets within 48 hours of birth is similar, preferably no more than 2 Mel 3 days. The weight of ② is about the same. Send the small ones first and the big ones later. ③ forbids the foster care of infected suckling pigs to a healthy litter of suckling pigs to prevent the spread of infectious diseases. ④ smear the adoptive mother's milk, iodine tincture and other methods so that the adoptive mother can not distinguish the smell of the foster pig, in order to prevent the suckling pig from being bitten by the foster mother. 6. Start feeding at the age of 5-7 days to ensure the cleanliness of the feeding trough. Add fresh feed at least 3 times a day. Suckling pigs to eat a certain trough feed can improve the growth rate and weaning weight of suckling pigs; second, it can reduce maternal consumption; third, lay a good foundation for weaning. 7. Castration young boars are castrated within one week of age. Apply iodine tincture after castration to prevent wound infection. 8. All instruments must be cleaned and sterilized for the next sow to give birth. 9. Suckling pigs that have reached the weaning age should be weaned. Immunity should be done before weaning. Nursing care of sows 1. Before parturition 5Mel washed the sows 7 days before delivery and rushed to the birth bed to adapt to the environment and keep them dry and clean. 2. The sows were forced to stand up and eat food after delivery to restore their physical condition. 3. Pay attention to protecting the breasts and nipples of sows, especially the first fetus. Make the most of every nipple. 4, early weaning sows with poor motherhood, less litter, poor body condition and poor lactation will combine the piglets with the piglets. 5. Add feed according to the regulations. Clean the trough after each meal to prevent moldy feed from being eaten by sows. Take notes. The ideal fat condition of sows after weaning should be 3 portions of fat, and those with good body condition before weaning should be gradually reduced to prevent the occurrence of mastitis; 2 portions of fat before and after weaning should not be reduced before and after weaning, and feed freely; 3 portions of fat should enter normal feeding, which can prevent mastitis and resume breeding as soon as possible. 1, 2 split fat should be raised to 3 split fat before breeding. 6. Clean up the feces in time, and one dung shovel had better be fixed in each column. 7. The inflammation of reproductive tract caused by birth should be treated in time. 8. The temperature of sow house should be controlled between 20-27 ℃. Heat stress can decrease feed intake, decrease lactation power and increase constipation. 9. Spray disinfection in the delivery room once a week.

The above are averages. In fact, feed should be added or reduced according to the weight of each pig to make it at the standard weight. 2. Sows eat little or no feed on the day of parturition. Increase the feed 1.5KG every day from the first day after parturition until it reaches the maximum. Such a slow increase in feed can prevent the milk from getting thicker and worse. 3. Reduce 2kg every day 2 days before weaning, and no more feed on the same day of weaning, in order to prevent poor absorption of milk after weaning and lead to mastitis. 4. Suckling pigs should be fed 550 kilograms from the 7th day of birth, and fresh feed should be added at least 3 times a day. The uneaten feed should be disposed of and the trough should be kept clean. Judgement of dystocia and midwifery 1. Symptoms of dystocia (1) prolonged pregnancy (more than 116 days of gestation, partial or total death of the fetus, which generally has little effect on the maintenance of pregnancy. However, fetal death will prolong the start time of normal delivery), vaginal discharge of blood-like secretions and meconium, no responsibility or slight failure to give birth. (2) after the sows gave birth to 1-2 piglets, the body surface of the piglets was dry and lively, but the sows did not give birth to pigs 1 hour later. (3) sows work hard for a long time, but can not give birth. 2. Several conditions and treatment of dystocia (1) weakness of uterine contraction is mainly manifested as sows with poor physique and more litters. 20 units of oxytocin. The opening of the cervix and no blockage of the birth canal should be checked before injection. (2) Fetal blockage is common in fat sows. It's caused by fetal enlargement and fetal malformation. Treatment is midwifery. (3) vaginal blockage, soft tissue injury of the birth canal, bladder swelling (which can be driven out of the birth bed for 10 minutes), constipation (can be enema with soapy water), tough vaginal valve (which can be broken by hand). 3. Midwifery, such as the lack of placenta or insufficient quantity, and the sow is still lying down, seems to have a slight responsibility; in addition, the sow does not produce pigs. (1) before midwifery, clean the posterior area of the sow. (2) cut the nails, clean the arms, disinfect and apply soap. (3) the hand is tapered into the vulva and moves forward between uterine contractions. (4) pull the piglet out with the sow. (5) penicillin treatment, in case of infection, the goal of the weaning procedure is to minimize stress on sows and staff through a correct schedule. The following is a typical weaning procedure:-first remove the weaned piglet, then remove the sow-quietly drive the sow to the breeding interval or elimination area-the enclosure of the breeding house should be able to see, smell and hear boars, preferably nose-to-nose contact. -when feeding the fence with leaky joints or solid cement floor, the temperature should be kept at 20 ℃, and the temperature with bedding grass can be reduced to 15 ℃. The following points apply to the group breeding system:-each sow needs a minimum of 2 square meters of enclosure, reducing stress and comfortable enclosure can help shorten the interval between weaning and mating. -the sows were divided into groups according to their body type and condition during weaning. -A boar and a weaned sow are fed in the same column for 1-2 days to help the herd. When mixing with the group, the enclosure should have a place of refuge. The purpose of feeding sows after weaning is to make sows produce as many healthy eggs as possible, and high-level feeding can produce more healthy eggs, so weaned sows should eat freely, and wet mixing will help to increase feed intake. Free feeding of weaned sows can also restore poor sows (especially parturient sows) and help to stimulate estrus. In order to interrupt breastfeeding, it is not necessary to restrict feeding after weaning. When weaning sows enter the breeding room, they should be injected with multivitamin (A, D, E). Pig farms with problems in the interval between weaning and mating can provide 200g glucose per day from 7days before weaning to mating. Some of the principles in part 2 of stimulating estrus and mating and the manual of artificial insemination also apply to weaned sows. Contact with boars contributes to a static reflex in weaned sows. Captive sows are easy to estrus, and sow herds can reduce the interval from weaning to mating and increase the pregnancy rate. However, feeding in inappropriate enclosure content can easily cause damage. Captive sows should be able to see boars and check every day after weaning. From the 4th day after weaning to mating, the sows should be regularly driven into the boar pen and come into contact with the boars. Each herd of sows uses an adult boar to check the symptoms of oestrus. Exchanging the pen of sows and boars can improve the effect of boars on sows so that each herd of sows has access to two boars. Habit is not a problem for weaned sows. If the sow is in estrus within 4 days after weaning, it is necessary to drive the sow into the boar pen every day from weaning to come into contact with the boar.

Haha-- thanks to the landlord-- if the sow is in estrus within 4 days after weaning Is it necessary to drive the sow into the boar pen every day from weaning to come into estrus within 4 days of contact with the boar? Why drive sows into the boar pen every day from weaning to come into contact with boars? -- good resources, useful, and learning.
