The Key Techniques of Raising Piglets in Early Autumn


1. Effectively keep piglets warm. In the early autumn, the climate change is not constant, and the temperature difference between day and night is large, which is not conducive to the growth and development of piglets. The insulation work must be done well, especially at night. The suitable temperature for newborn piglets is 29-35°C for 0-3 days, 25-29°C for 4-7 days, 22-25° for 8-14 days, and 20-22° for 15-21 days.
For conditional pig farms (households), energy-saving electric heating plates can be placed in the house, and the temperature of the electric plates can be adjusted according to the requirements of the piglets on the temperature, and the heat preservation effect is good. It is also possible to install a far-infrared heat-retaining lamp in the piglet insulation box or the piglet feed-bar, generally using 100 to 175 watt bulbs. Hang the bulb in the piglet's lying position) and control the temperature by adjusting the height from the ground. If you do not have the above conditions, you can also use a woven bag wrapped with soft weeds, laying in the piglets lying in place, as a mat grass, the general thickness should be more than 10 cm. However, the habit of regular piglet rearing should be trained to keep the mat grass dry.
2. Prevent sows from pressing on piglets. After the birth of piglets, there are many occurrences of sows dying and squeezing piglets, which generally account for 10% to 30% of the total number of deaths, and even as high as 50%, mostly occurring within one week after birth. The main reason is that sows are weak or obese, and they are unresponsive. Piglets, especially frail and productive for 1 to 5 days, are narrow and easy to be pressed to death. Specific approach: First, care for newborn piglets, within one week after birth, nursery boxes should be used to separate the mother piglet, sow every 2 to 3 hours to suckling once. The second is to set a nursery bar in the place where the sow house is against the wall; use a round wood or iron pipe to set a nursery bar 25 cm away from the wall and the ground to prevent the piglets from squeezing when the sow is lying down on the wall. The third is to set up a nursery room, use a board or brick in the sow house to build a nursery room closed around the door, leaving a small door (for piglets out), regularly release the piglet sucker, which greatly reduces the piglets being pressed opportunity. In the production, one of the above may be selected.
3. Iron, selenium supplement and feed. Iron deficiency anemia prevails in newborn piglets. Iron is an essential element for hematopoiesis and prevention of nutritional anemia. It is also a component of cytochrome enzymes and various oxidases. The pig's iron reserves are only sufficient for 6 to 7 days. If iron is not added, appetite loss, rough coat, pale skin and stagnation due to iron deficiency usually occur around the age of 10 days. Therefore, piglets must be iron supplemented 2 to 3 days after birth. It is usually injected intramuscularly with 1 to 2 ml of muscle or intramuscularly with 1 to 2 ml of iron dextran or dextran iron.
Selenium and vitamin E have similar antioxidant effects, and it is related to the absorption and utilization of vitamin E. In selenium-deficient piglets, diarrhea, white muscle disease, etc. often occur in piglets. Most of the diseased piglets are upper-middle-nutrition or fast-growing piglets, with normal or low body temperature, hoarseness, and swaying, and then hind limb paralysis. Generally, 0.5 ml of 0.1% sodium selenite or vitamin E injection is intramuscularly injected 3 to 5 days after the birth of the piglet, and 1 ml is injected before weaning. In piglet feed, 0.1 mg of sodium selenite is added per kilogram of feed.
Training piglets from breastfeeding to eating feed is the top priority in feeding piglets. It can train the digestive tract of piglets, improve digestive ability, prepare for a large number of feed intake, and reduce the incidence of blight. The sooner the piglets eat, the better. Generally, they can be bred from the age of 5 days. The above feed was wetted with a small amount of water, and the breeder hand wiped it into the mouth of the piglet and wiped it 3 to 4 times a day. At the same time, the piglet was added with a prophylactic food for the piglets (florfenicol, electrolysis multidimensional, etc.) for 5 days. Prevents diarrhea. Afterwards, feed can be placed in the piglet feed tank to allow it to feed freely. At the same time, to ensure adequate clean drinking water, piglets grow rapidly, metabolism is strong, and the amount of water required is greater. Water supply should be guaranteed. If the drinking water is insufficient, the piglets will grow slowly, or the piglets will drink dirty water, urine, etc. and cause diarrhea.
4. Scientific immunization procedures and drug prevention. After the birth of the piglets, two doses of immunization (preemptive immunization) were given to the swine fever vaccine. After 2 hours, the piglets were suckled. A 16-day-old neck was intramuscularly injected with 1 ml of inactivated swine edema disease. 20 ml of intramuscularly injected blue ear vaccine 2 ml. A 25-day-old cervical muscle was injected with 2 ml of trivalent diarrhea in piglets. 28-day-old pigs were injected 0.5 ml of atrophic rhinitis. 30-day-old pig pseudotyroid vaccine was injected 0.5 ml.
The diarrhea is one of the most common diseases of suckling piglets, and it is more common in yellow and white diarrhea. There are many causes of morbidity, mostly caused by cold, indigestion, and bacterial infections, and comprehensive preventive measures must be taken. Disinfect the delivery room thoroughly before farrowing. Keep the delivery room dry, warm, and fresh air throughout the lactation period. Pay special attention to the piglet's insulation. In addition to vaccination, medications should also be used for prevention. Once onset, oxytetracycline (10 mg/kg body weight) may be given intramuscularly and florfenicol (20 mg/kg body weight) may be given twice a day for 3 days. For severely dehydrated piglets, oral rehydration salts can be used. Its formula: 3 grams of sodium chloride, 2.5 grams of sodium bicarbonate, 1.5 grams of potassium chloride, 20 grams of glucose, add water to 1000 milliliters, can enhance the disease resistance of piglets, reduce Mortality, if combined with antibiotic treatment can significantly shorten the course of treatment. Prevention of respiratory diseases in piglets can be done with "demimeter first" (Pfizer, USA) long-acting oxytetracycline. After 3, 7 and 21 days of age, piglets are injected with 0.5 ml each. Before and after the sow giving birth, one week each, 80% tiamulin 125 g/day plus 15% chlortetracycline 300 g/day plus amoxicillin 150 g/day was added to the feed.
5. Do a good job of sanitation and disinfection. To keep the pens clean and dry, excrement and rubbish should be cleaned in time, and the mat lining should be changed frequently. Let the sow develop regular scheduled excrement and urine, do not wash the pigpen with water, timely removal of house waste, so that the house is dry, no odor. Conscientiously do a good job of disinfection, pens, troughs and other regular disinfection, generally winter and spring every 2 to 3 days disinfection 1, take 2% to 3% of sodium hydroxide, 100 poisoning, peracetic acid, Wei Kang The use of other disinfectants alternately can effectively kill various viruses, bacteria, mycoplasma, fungi and spores.
In addition, let the newborn piglet eat colostrum as soon as possible and fix the nipple. The feed to be fed should be properly matched. It is best to feed high-quality commercial pig feed and not feed poorly and moldy feeds to prevent piglets from becoming ill. Take the above comprehensive measures to maintain good early autumn suckling pigs.
