In the production work, the cultivation measures are roughly divided into three stages according to the characteristics of the piglets. (A) after birth to 7 days of age, this stage focuses on the survival of piglets, fixed nipples, early drinking colostrum. Newborn piglets have the instinct to find the sow's nipple and are selective to the nipple and can establish a very stable conditioned reflex. Since the milk yield of each nipple is different, the piglets should be artificially trained to fix the nipples within 2-3 days after birth. Generally, the strengths and weaknesses should be fixed to take care of the middle. Most piglets only take up one nipple, but also suck two adjacent nipples. Colostrum is an essential nutrient for piglets and is rich in dry matter, protein, minerals and vitamins. Colostrum contains magnesium salt, which promotes digestive tract wriggling in piglets and facilitates the discharge of fetal stools. It also contains immunoglobulins that enhance the disease resistance of piglets. If a piglet does not eat colostrum, it will grow poorly or become a dead pig or die. Therefore, piglets should drink colostrum as soon as possible after birth. 2, to prevent death, to ensure survival. During the first few days, the piglets had weakness in their limbs and sluggish movements. Especially in the cold season, they often nestled in the abdomen of the sow or slept on each other to get warm. They slept deeper and were often overwhelmed by the poorly-bred sow. Pressure prevention measures can be taken with various kinds of equipment, such as the use of pressure-proof racks, branching grilles, etc. The effective methods in current production are based on the difference between the quality of sow motherhood, and the general principle is to strengthen day and night nursing within the birthing season. . On the other hand, for individual mothers with poor quality, all litter piglets are placed in boxes or baskets within 3-4 days postpartum, and the milk is released once every 0.5-1 hour before being caught in the box. 3, cold and warm. The optimum ambient temperature for newborn piglets is 30-35°C, and the temperature is too low, especially in the early spring. Piglets often suffer from colds and pneumonia due to wind and cold. Cold and warm measures: It is required to maintain a constant temperature in the pig house. The measure is to use warm boxes and other equipment. You can put a piece of wood on the corner of the sow pen and spread the short grass to let the mother sleep. Pay attention to changing mats. 4. Prevent anemia and supplement minerals. Piglets are prone to lack of minerals, especially iron and copper. Within 3 to 4 days after birth, it can still rely on its own storage and supply, but lack of iron in milk will hinder the formation of hemoglobin. Insufficient hemoglobin affects the transport of oxygen and intracellular metabolism and is characterized by rough hair, pale epithelium, loss of appetite, and growth arrest. The method of preventing anemia is currently used in 3-5 days after birth of piglets, 2.5 grams of ferrous sulfate, 1 gram of copper sulfate, dissolved in 1000 milliliters of water and used to drop the sow on the nipples of suckling pigs to inhale them with a dropper; or 7 days after birth, each injection of iron and cobalt injection 2-3 ml; or put a platter, put salt, bone meal, charcoal, red clay in the dish, so that piglets free arched. 5, ground water, ground water. The fast growth of piglets, coupled with the high energy of sucked milk, requires a lot of water. If you do not meet the required amount of water, on the one hand affect the increase in weight, on the other hand piglets have to drink dirty urine, resulting in diarrhea. If there is no water dispenser, the piglets should start drinking water in shallow pans for 3 days after birth. (B) The key to the cultivation of 7-30 days old is to focus on milk larvae as the center, training piglets to eat early feed 1, early feed, and enhance gastrointestinal function. Early training of piglets to eat is one of the key measures to enhance digestive function, enhance physical fitness, resist disease, and increase weaning weight, and we must do everything possible to break through the feeding gap. Generally, 7 days after the piglet's birth, piglets start to grow their teeth, itching of the gums, and the characteristics of the magpie hard objects. Spread some fried barley, corn seeds, etc., in the columns; or sprinkle some chopped green material and fresh seeds. Sweet and tender feeds such as potato chips and squash make the piglets happy to try it; or use the piglet's imitating habits and set up a common feeding trough so that they can learn to eat piglets that are accustomed to eating. 2, fine rations to meet the nutritional needs of piglets. Piglets should eat high protein, vitamin content, good palatability, easy to digest and absorb feed, to meet the nutritional needs of muscle, bone and tissue and organ growth and development. For this purpose, the ingredients should be combined with specific conditions after consulting the feeding standard table. 3, grazing exercise, enhance physical fitness. From the 7th day after birth, if the weather is fine, it is advisable to go out with her sows for grazing, graze on earth, and sunbathe 1-2 times a day. The starting time should not be too long. Even after 1 month of age, it is not recommended to exercise too much. For a long time, to avoid excessive fatigue, affecting growth. 4. Do everything possible to prevent and control white diarrhea. 14-28 days after birth, the physiological function of the piglet stomach is not yet perfect, plus the piglets love the dirt, drinking water, and changes in environmental conditions, such as drastic changes in sunny and cool, often prone to cause white phlegm, the incidence rate of up to 60% -80 %, even if the duration of the disease is short, it will affect growth, and severe cases will result in stiff pigs and even death. Prevention and control measures are mainly to do a good job in pig house hygiene and cold warm work, training piglets to eat early, pay attention to the quality of sow milk, and timely symptomatic treatment after discovery. (3) 30-60 days of ageing At this stage, the piglets are accustomed to eating and the daily weight gain can reach 500 grams. At this time, the central task is to try every possible way to encourage the piglets to have a big meal and catch the balanced development of the whole litter. Weaning heavy, heavy nest request. 1, grab food, promote growth. The piglet is about 1 month old and has an increased viability, improved digestive function, and a special love of eating. Feeding less frequently and increasing meal times are the basic conditions for maintaining a prosperous food. In order to utilize the habits of piglets that like to eat fresh ingredients and reduce feed wastage, they are generally fed 4 times before the age of 30 days and 5 times on 30-40 days, 40- 60 days old, including 1 midnight. Diet formulas should be relatively stable so that piglets do not choose to eat. At the same time, there should be no quantitative food order, so that it is not wasted to eat. 2, timely castration. Piglets that are not used for breeding should be castrated in a timely manner. Generally, piglets are already accustomed to eating and have strong resistance. They should be suitable around 1 month of age. 3, immunization. 20 days after birth injection of swine edema, paratyphoid fever double vaccine, 30-40 days of injection of swine fever, swine erysipelas, swine flu vaccine triple vaccine to prevent the harm of these several infectious diseases.
