Feeding technology for suckling piglets
Good heat preservation and anti-pressure work. Newborn pigs need a temperature of 35°C to 29°C at 0-day to 3rd day of age, 29°C to 25°C at 4 days to 7 days, and 25°C at 8 days to 14 days of age. 22°C, 15 to 21 days old, 22°C to 20°C. Early spring is cold, windy, and volatile, which is not conducive to the growth and development of piglets, and insulation is very important. 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. Can also be installed in the piglet insulation box or pig feed bar far infrared heat preservation lamp (preferably imported from Italy, Philips pig warm infrared light bulbs), generally with 100 watts ~ 175 watt bulbs. Hang the bulb in the piglet's lying area and control the temperature by adjusting the height from the ground. If you do not have the above conditions, you can also use woven bags on the benzene board (PS board) on the incubator on the ground, and then pad thick grass, the general thickness should be more than 10 cm, but the practice of training piglets cultivated regularly scheduled point excretion habit Keep the mat grass dry. Preventing sows from pressing on piglets After sow birth, 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 within one week after birth. The main reason is that the sows are frail or obese, they are unresponsive, the piglets are weak and weak, and the birth circle is narrow. In particular, piglets from 1 day to 5 days are easily pressed to death. Specific approach: First, care for newborn piglets, within one week after birth, should use nursery box, separate the mother piglet, every 2 hours to 3 hours sow the sow 1; the second is to set the nursery bar, in Place the nursery bar 25 cm away from the wall and the ground with a round wood or iron pipe to prevent the sow from squeezing the piglet while lying down on the wall. The third is to set up a nursery room. The sow house is built with planks or bricks to build a closed room with a small door (for the piglet to enter), and the piglets are fed regularly so that the opportunity for the piglets to be pressed is greatly reduced. In the production, one of the above may be selected. Iron deficiency, replenishment and supplementation are commonly used in newly born piglets for iron deficiency anemia. Iron is an essential element for hematopoiesis and prevention of nutritional anemia. It is also a component of cytochrome enzymes and various oxidases. Iron stores in piglets are only sufficient for 6 days to 7 days. If iron is not added, about 10 days of age, the loss of appetite due to iron deficiency, rough hair, pale skin, and stagnant growth will occur. Therefore, piglets must be iron supplemented 2 to 3 days after birth. It is usually injected intramuscularly with 1 ml to 2 ml intramuscularly. It is also possible to intramuscularly inject 1 ml to 2 ml of iron dextran or dextran iron. Selenium and vitamin e have similar antioxidant effects, which are 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. Normally, 0.5 ml of 0.1% sodium selenite or vitamine injection is intramuscularly injected 3 days 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. Available "Prinner" high-energy suckling pig full-priced feed or Beijing Resources 9410 suckling pig feed. The above feed is wetted with a small amount of water. The breeder wipes the piglet by hand and wipes it 3 times to 4 times a day. At the same time, piglets are added to the feed to induce prophylactic drugs (florfenicol, electrolysis, etc.) for 5 days. Can prevent 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. Scientific immunization programs and drug prevention have a large temperature difference between day and night in early spring, and the weather is fickle. Coupled with the weak disease resistance of piglets, piglets are most vulnerable to diseases. In addition to strengthening feeding management, they must also develop scientific immunization procedures. After the piglets were born, two immunization doses (preemptive immunization) of swine fever vaccine were injected. After 2 hours, breast-feeding was performed; 16-day-old cervical injectable porcine edema disease inactivated vaccine 1 ml; 20-day-old intramuscular injection of 2 ml of blue ear vaccine; A 25-day-old cervical intramuscular injection of 3 ml of trivalent diarrhea vaccine for piglets; 0.5 ml of porcine atrophic rhinitis vaccine at 28 days of age; and 0.5 ml of a pseudorabies vaccine for 30 days of age. 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. After the piglets were born without breastfeeding, 0.1 g of “suckling swine opener†was given to each pig. Use 3 days. Add "Piglet Prevention Drugs" to the feed and mix in the feed for 7 days. 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. It can enhance the disease resistance of piglets and reduce the mortality rate. If combined with antibiotic treatment can significantly shorten the course of treatment to prevent piglet respiratory diseases can be used by Pfizer's "Demeter first." Long-acting oxytetracycline was injected at 0.5, 3, 7, and 21 days after birth. Sows were fed 1 and 8 weeks before and after the sow, adding 80% tiamulin 125 g/day + 15% chlortetracycline 300 g/day + amoxicillin 150 g/day to the diet. "Addition can also be added to the feed." "Sow perinatal prophylaxis medicine", plus 10 grams per 100 kilograms of feed, for 7 days, can effectively control the occurrence of respiratory disease in piglets. Do a good job in sanitation and disinfection work to keep the house clean and dry, excrement, garbage should be cleaned in a timely manner, advance grass should be replaced frequently. Let sows develop regular scheduled excrement and urine excretion, do not wash the pigpen with water, remove the feces in the house in time, make the house dry, and there is no odor in the insulation. Conscientiously do a good job of disinfection, housing, food trough, etc. to be regularly disinfected, usually winter and spring every 2 days to 3 days disinfection 1 times. Can use 2% to 3% of caustic soda, kill poison, peracetic acid, Wei Kang and other disinfectants alternately use, can effectively kill all kinds of 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 spring suckling pigs.
