Management of piglets at birth
The management of suckling piglets on a large-scale pig farm is not simply a matter of survival rate, but also weaning uniformity. Excessive physical differences will cause inconvenience to subsequent abortion and fattening, affecting the normal turnover and balanced production of the pigs. For this reason, providing piglets with individual uniformity, heavy weaning mass, and strong vitality is the main target for feeding piglets during lactation.
(l) Dentures and tail-cracking Newborn pigs should be weighed, beaten, cut, and broken in 24 hours. Cut off the umbilicus to leave 75px is appropriate, broken end 5% iodine disinfection; it is necessary to play the ear number, try to avoid the blood vessels, the gap to be 5% iodine disinfection; cutting forceps 5% iodine disinfection after the tooth root Cut off the upper and lower canine teeth at the upper and lower sides, weak teeth do not cut teeth; when the tail is broken, the tail roots are cut at 75px, and 5% iodine is disinfected. Its purpose is to prevent "biting tail" evil caused by infection. Cut off 1/3 to 1/2 when the tail is broken. The operation should be quick to reduce bleeding.
(2) Early consumption of colostrum colostrum The secretion of milk from the first 3 days after the birth of the sow, which contains a large amount of immunoglobulin, can improve the disease immunity of newborn piglets. Therefore, within 24 hours after the birth of the piglet, the piglet should have sufficient colostrum. For artificially nursed piglets, at least the sows should be fed 2 to 3 days of colostrum. The role of colostrum is mainly:
1 promote the excretion of meconium;
2 rich in immune globulin, enhance piglets' resistance to the outside world;
3 The content of vitamin A is 10 to 100 times more than normal milk, and the content of vitamin B, BZ is also extremely high;
4 Feed antibodies to piglets through colostrum. After birth, the piglets have limited reserves of energy in their bodies. If they cannot replenish in the short term, they will experience hypoglycemia. At the same time, colostrum contains immune globulin, which can resist the invasion of various pathogens. Therefore, it is recommended that the piglets eat colostrum as soon as possible after birth, and do not need to give up milk before they are finished. In order to prevent indelible marking of piglets that have eaten colostrum with a marker, it is better to remember which of the teats they eat.
(3) Many people agree that fixed teats, but they can't do it, mainly because they are too cumbersome, they have a lot of work and they have a long time. The following methods can be taken: usually the piglet is caught in the incubator, breast-feeding at a regular time; the strong and weak piglets are separated by a baffle; the weak piglet is breast-feeding first, and the weak piglet is finally caught when all the milk is finished, making it more A lot of feeding time; notes with every piglet's feeding position, although this work is tedious, but every litter can be fixed in 2 days.
(4) Oral antibiotics 1 streptomycin plus 2 kanamycin before colostrum is eaten, and each litter of piglets is protected against the diarrhea caused by early-onset E. coli.
(5) Insulation of piglets The subcutaneous fat after birth is thin, the cold resistance is weak, and the ability to regulate body temperature is poor. It is necessary to provide suitable ambient temperature. The temperature in the incubator of piglets can be gradually reduced from 32 to 35°C at the time of first birth to the time of weaning. 23-25°C. According to the status of the piglets when lying down, determine whether the temperature is appropriate; if the piglets are suitable, they will lie evenly in the incubator and sleep comfortably; if the temperature is too high, the piglets will be separated and the head will be blown in with a gap. The edge or mouth of fresh air; if the temperature is low, it will crowd and pressure. When the temperature is too high, some pigs will hide outside the box and for a long time they will suffer from cold diarrhea. The suitable ambient temperature for piglets is 1 to 3 days of age 30-32°C; 4 to 7 days of age 28 to 30°C; 8 to 30 days of age 22 to 26°C. For suckling piglets, use warm lamps or bed warming. Good insulation measures have the following advantages:
1 increase the weaning survival rate of piglets;
2 increase the average weaning weight of piglets;
3 improve the uniformity;
4 helps the formation of antibodies.
(6) Suitable Humidity The optimum humidity for pigs is 50% to 80%, which is relatively wide and therefore easily overlooked. Especially when the relative humidity of piglets reaches 80% or more, piglets are prone to diarrhoea. On the other hand, when it is dry for a long time, coupled with poor ventilation, pigs are also susceptible to respiratory diseases. Therefore, efforts should be made to maintain proper humidity.
(7) After giving birth to the sow, the piglet can not lactate due to puerperal fever or other diseases, or because the number of litters exceeds the number of effective sows in the sow, the additional piglets can be given to other sows that have been delivered at roughly the same time for nurturing. After the piglets had eaten colostrum, they had to adjust for proper feeding and fostering, trying to make the number of piglets equal to the number of effective sows in the sow, and prevent the unused nipples from shrinking, thereby affecting the lactation performance of the next fetus. The foster piglets are carried out as soon as possible after birth, and the birth date of the mother and the foster mother is as close as possible. The difference in the age of the piglets does not exceed 3 days. The big piglets are sent out and when the piglets are fostered, they must be wiped with the urine or milk of the nursing mother. The whole body is wiped out so that the adoptive son has the same smell as the foster mother and is put into the foster mother's piglet at night. When the foster piglets are breastfeeding for the first time, they must be carefully observed to prevent the foster mother from harming the foster piglets.
(8) Iron supplementation to prevent anemia Normal piglets have 15 mg of iron at birth and 1 mg per day through colostrum, and pigs require 10 mg of iron per day. Within two days after birth, piglets are injected with iron, such as iron blood or rich blood, blood serum, etc., and iron is injected in about 21 days to prevent anemia.
(9) Castration 3 - 7-day-old boar castration, castration must be thorough, the incision should not be too large, postoperative 5% iodine disinfection. After the piglet is completely fixed, wash the surgical site and its surroundings with soap first, wipe with alcohol and wipe with iodine, and press the scrotum tightly with the thumb and index finger of the left hand, and place the testicle on the right hand to open a long mouth. Cut 175px and use the same method to remove the other testicle. After the operation, wipe the wound and surrounding area with sterile cotton or gauze, then apply some dilute iodine. The wound part does not have to be sutured.
(10) Piglets' training and watering piglet development is rapid. After 1 week of birth, the body weight is twice that at birth. After 3 weeks of lactation, the milk yield and nutrition will gradually decline, and the growing piglets There are more and more nutrients needed, so artificial supplements are needed to supplement the insufficient amount of pig's milk. Feeding materials are started 5-7 days after birth, keeping the feed trough clean and the feed fresh. Tim Tim added less, night to add a material. The number of feeds per day is 4 to 5 times. Supplements should also pay attention to nutrition, easy to digest, pay attention to the quality of protein, while providing clean drinking water. Trough feeding has the following advantages:
1 stimulate the secretion of digestive enzymes;
2 Make up for the lack of sow lactation;
3 improve the uniformity of piglets and the breeding rate;
4 Weaning milk early to increase breeder breeding.
(11) Weaned piglets were weaned at an average age of 21-25 days, weaned at one time, kept unchanged, and did not change feed. Before and after weaning, feed 3 days to eat salt to prevent stress. One week after weaning, the feed was gradually changed, and the weaning head was paid attention to the restriction for 2 days to prevent the indigestion from causing diarrhea. Sows that are overweight and emaciated during lactation should be properly weaned in advance and must be properly contaminated 3 days before weaning. When weaning, pigs that have reached the age but whose weight is too small are exchanged with pigs that are later but normal growth, which ensures the uniformity of the transferred piglets and prevents the disadvantages of the weak pigs becoming difficult to survive when they are transferred to the pens.
2. Prevention of suckling piglets
(l) Sows should be given injections of transmissible gastroenteritis, epidemic diarrhea, rotavirus vaccine and Astragalus membranaceus, B. catarrhalis K88, K99 30 days before birth.
(2) Self-vaccine: Fresh sows from suckling pigs and sows in the first 2 days after the start of the first three weeks of gestation were fed with the feed and fed for 2 days.
(3) The sow room should be cleaned and disinfected one week before the sow is placed in the delivery room. The sow should also be cleaned and disinfected when entering the farrowing room.
(4) Injecting beneficial sml within 8 hours after sow giving birth.
(5) After oral administration of piglets, piglets were given oral medications before colostrum: 1 litter of piglets was given either streptomycin 1 or kanamycin. Severe farms with yellow peony and white lice can be used for 3 to 5 days. Or take oral oil (8501) to take 50ml/kg body weight. It can also be used to benefit and oral Po Hong Su.
(6) Piglets should be wiped with 0.1% potassium permanganate before eating colostrum, and pigs should be fed with a few drops of milk.
(7) Intramuscular injection of 200 mg of dextrose, iron, etc. is injected intramuscularly at 3 days of age, and sodium selenite should be injected into selenium-deficient areas.
(8) Give the sow a clean drinking water, teach it to the piglet at the age of 5 to 7 days, or directly use the puffed pig feed.
(9) Strictly follow the standard feeding ingredients and feeds of the nursing sow to prevent the piglets from being over-concentrated during the first week, causing the piglets to squat, and not to feed the moldy feed of the sow so as not to cause the piglets to squat.
(10) Clean, dry, ventilated and suitable temperature, avoid water flushing. After the fecal matter has been cleaned of feces, it should be wiped clean with a mop that wrings out the disinfectant.
(11) In the event of a diarrhea, killing the virus and removing it should be carried out at the same time. The ground can be used to sprinkle lime powder on top of the yellow and white lice, and immediately remove it. The tiller pen is wiped clean with a mop twisted on the disinfectant.
