The term "multiple piglet" refers to a high yielding sow producing more than one fetus (12 pigs), that is, a suckling piglet. In swine production, especially in rural areas, although the mother's high yield and Aberdeen's two pigs are strong, the problem of inability to grow young children is not well resolved, and the survival rate of suckling piglets is low, growth and development are slow, and economic efficiency is poor. We believe that the high yield of sows and the robust group are, of course, the basis for raising the piglet production level and increasing the quantity and quality of the benefits; only in this basic soil, give full play to human technical skills and adopt a series of technological measures for superior education. In order to give full play to the long-term potential of suckling piglets, to maximize the 50-day weaning weight and achieve the best economic benefits. To this end, on the issue of multiple births and suckling piglets, we should discuss some personal experiences for reference. First, put the temperature of the first-born piglet off, and strive to fully live in our north, sow breeding sows in the cold winter, put the first newborn piglet temperature should be placed on the first pass to pay attention. When sows are farrowing, the cold stimulation directly threatens the life safety of newborn piglets. If no measures are taken to increase the temperature and temperature, the first phenomenon is that the piglet does not open mouth to feed milk because it is frozen; long-term cold stimulation cannot be alleviated, and hunger and freezing death is an important reason. This requires the sow breeder, starting from the actual situation, without losing the opportunity to do the pre-natal, mid-production and post-natal heat preservation and temperature increase measures of the Wazhen sow. (1) Prenatal insulation measures Breeding sow breeders must accurately predict the date of production of the winter sows; a series of insulation measures must be made before the expected date of production. 1. Open the production house to buckle the plastic shed; 2. Block all vents; 3. Screw the plastic film around the front and rear windows; 4. Produce thick and soft grass mats within 3 days before delivery; 5. Hang the cotton curtain in the doorway . (B) The post-natal warming measures during the production period are not enough for the sow to adopt insulation measures before delivery, and the measures for increasing the temperature during the post-production period must also be made. 1. The method of increasing the temperature of the infrared light is to set up the infrared lamp safely and reliably in the production house before the sow is brought into production. When the sow is littering, the light bulb is regulated at a height of 40-50 cm above the ground. The general requirement is to both reach the piglet and the sow's abdomen, and turn on the switch to warm it up. Infrared lamps are available on the market, and the cost is not high. The effect of warming is very good. It can not only ensure the piglet can eat colostrum in time, but also promote the blood circulation of sow breast tissue, which is conducive to lactation and increase milk yield. Therefore, the environment is warm, the house is dry, and at the same time it can reduce the incidence of yellow or white disease. However, attention should be paid to adjusting the distance between the lamp and the piglets so as to prevent the piglets from being burned so as to prevent the electric shock of the sow. 2. The modern warming measures are conditional and the households can use the modern temperature-increasing equipment such as the piglet electric pad and the incubator and the effect is better. 3. The internal coal stoves in the homes do not have a good temperature increase condition. It is also a good idea to produce coal stoves in the production houses. However, we must pay attention to the elimination of excess smoke and avoid gas poisoning. 4, on-site firewood heating to increase the temperature in the absence of the special circumstances of the warming, when the sow on the ground to take dry firewood, fire heating products as long as the attention to the exclusion of indoor smoke, but also a good warming effect. In short, if a sow can think about it during the winter, she can think and do what she can and can't sit idly by. She must not be careless. Second, the good newborn pigs eat enough colostrum, improve the body resistance to disease Colostrum is sows within 2 to 3 days after the secretion of milk for the colostrum, after 3 days of secretion of milk is often milk, colostrum is a newborn piglet Life's milk, other nutrients can not be replaced, it plays a key role in the quality of life of postpartum piglets. Because colostrum contains money and salt, it has a laxative effect. After eating piglets, it is beneficial to the elimination of meconium. In particular, containing immunoglobulins, piglets can obtain antibodies after eating, improve the body's immune system, enhance physical fitness, so after the birth of piglets do everything possible to do their best to allow their piglets to eat enough to eat colostrum in time is a major event, must be. Practice has proved that newborn piglets cannot eat enough colostrum to eat, and it is difficult to raise children. Third, a good fixed nipple off, to ensure that the growth and development of neat piglets fixed nipples are artificial to make their own post-natal piglets to eat each fixed nipple. The meaning of fixing the nipple is that the mother and the child are peaceful, the sow can normally put the milk completely, the piglet can normally eat the milk evenly, and avoid the fierce fighting of the weak food, and the growth and development are even and tidy, so that the small dead pig does not appear. (A) Fixing the nipple principle The small and weak piglet is fixed on the nipple in front of breast milk and the big, etched piglet is fixed on the nipple on the back of breast milk. Once fixed, it will remain unchanged for a few days. If it is not fixed, it will not be rested. After practice verification, the first few pairs of milk in the front of the postpartum sow have more milk than the latter, and fixing the small and weak piglets on the nipple in front of the breast milk can make up for the shortcomings of the weak piglets, which is the uniform growth of the piglets. The truth. (b) the method of fixing the nipple 1, solid small is not solid, the production staff side fixed edge, the weak and small piglets directly on the nipple in front of breast milk, a little care. 2. Balanced method: After the pigs in the whole nest are finished, the consignee will balance the size of the whole litter, divide the size of the litter, and fix the small and weak piglets on the nipple in front of the breast in sequence. To eat milk, big and strong piglets are fixed on the nipples behind the breast milk. Care is taken to avoid misplacement. 3, board fixing method: For example, to implement the full balance method, in order to facilitate the success of a fixed, can use a rectangular board, when the sow put milk from the size of the interval, the rear of the piglet is not easy to cross the board, naturally behind the milk It is easy and easy to succeed. 4. Mandatory fixation method: Focus on the large and strong piglets that nurse behind and take care of the contenders. It is not necessary to consider whether or not to eat milk, and it takes a long time to eat milk at the back. 5. Penalty fixing method: There are indeed very few piglets competing for nipples and hardships. Such piglets can be fixed by punitive measures. The method is to prepare a box-shaped wooden box in advance, preferably on the side of the cage inside the cage. When the sow puts milk, quickly catch the hard-to-replaced piglets in the cage, let it be in the side view Mod other piglets eat milk and put it back when the sow is released. This way, the milking opportunities are so many times that when the sow re-feeds milk in an extremely hungry state, the cage door is opened and the piglets are punished quickly. Run to see the nipples behind the nipples and hold the milk. After a little care, you can fix it. Fourth, early enticement to a good feed off the piglet to eat fast, long, early and long-term lure is the early training pigs expected to eat, eat the night feed to lay a good foundation, to promote the piglets to eat more quickly, so as to obtain the largest 50 days Weaning nest weight. 1. Early lure-feeding Early lure-feeding is a key technology for the early admission of piglets. The earlier the lure-feeding time, the faster the arrival time of entering Wangshi. 1 Induced feed composition: Take half of corn and soybeans, and fry them and process them into powder for later use; 2 The time for attracting food is early, starting from the morning of the 5th day after birth; 8 The method of attracting food: Take appropriate amount of food ingredients in the dish Add sugar to the dough and stir into a dough. Grab the piglets on one side of the chest with one hand, and use one elbow to hold the buttocks of the piglets. The two fingers work together to open the mouth of the piglet, fix it with one hand, and squeeze one mass of material in one hand, quickly wipe the back of the mouth and put it in place. Open piglets, so wiped all over the whole litter of piglets, wiping material 5 to 6 times a day, in order to lay a good foundation for the next night, you can arrange to wipe the material at night, so seriously adhere to wipe 3 to 5 days, piglets can be Complete the process from the expected feed to the feed and enter the feed phase. 2. After the feeding pigs have eaten materials, they can place them in a shallow, large dish, or they can fly on a clean floor and allow their piglets to eat. In order to facilitate the formation of feed reflections for piglets, a long bamboo rod is used from the beginning of the food intake, and a certain number of signals are attached. After feeding, the piglet is used to stir the piglets and go to eat. After the feed is reflected, the piglets will listen. When you reach the bamboo pole, you can quickly get up and eat. 3, grab food and night food to maximize the promotion of piglets eat fast piglets eat soon after entering the Wang Shi food, in addition to the normal feed, in this phase, feed at night around 11:00 , with practical significance. With our experience, plus night food and no night food compared, plus piglets 50 days weaning average weight of a weaning 2 to 3 kg, which adds a lot of nightly benefits. 4, on the issue of piglets after the feeding of feed materials, feed should be the best, but the piglet feed, in different regions have different difficulties. First, the purchase of raw materials is incomplete; second, the quality is not easy to be reliable; and third, it is not economical. It is better to buy quality compound feeds or concentrates in the market, and use them directly to feed piglets, which is convenient and economical. V. Prompt treatment to ensure that everything in the cultivation process is smooth In the process of cultivating piglets, we sometimes encounter unexpected problems, and we must promptly eliminate them and deal with them in time. 1. The sow tube is blocked. The sow's breasts are well developed. There is no milk discharge from one or more nipples. This is why the nipple duct is blocked by dirt. At this point, a 12-needle needle should be cut off with a sharpened edge, a sharpened bald edge, placed on a syringe, and the blocked nipple should be fixed by one hand. The syringe should be directed at the outer orifice of the nipple and slowly enter the nipple tube. The piston should be plucked and there should be a suction tube inside the breast. , Withdraw the syringe, finger squeeze the nipple, there is milk spray, that is, pass milk. 2. Lack of lactation Insufficient causes of lactation in sows Many reasons, such as lack of milk in the farrowing period, and even no milk, are major problems. It is necessary to take prompt prolactination and milk increase measures. The emergency measure is to first inject oxytocin into the sows. Oxytocin has both oxytocin and prolactin effects. Then, the sows are fed with brown sugar soybean milk soup, and then tablets or powders with proper prolactin-enriched milk are added to the sow. Otherwise, accidents in which the piglets do not eat enough milk will inevitably occur. 3. The more productive the sows are, the higher the number of sham-dead piglets that can be activated in the dying piglets, and that the sham pigs are all medium-sized individuals. Although there is not much chance of activation, we should adopt a positive attitude and adopt a proven method. Activation can activate. 1 Identification of suspended dead piglets: After the birth of the piglet, the body becomes soft and there is no breathing, but the base of the umbilical cord fluctuates, and the heart beats. Such a piglet, that is, a false-dead piglet, should immediately take active measures for emergency treatment. 2 Activated method of suspended animation piglets A. Artificial respiration: First, massage the piglets on both sides; Second, lift the piglets on two hind legs, continuously pat the chest and back, and promote the smooth flow of the respiratory tract. B. warm water bath: the piglets will be suspended immediately with their hands to support the pig's head and buttocks placed in warm water 38 °C ~ 39 °C, so that the head exposed water, abdomen upward, to make a flexion, if breathing occurs , Dry the skin, give warmth, and feed as early as possible. C. Iodine stimulation: Use fresh iodine tampon and wipe on the nostrils on both sides of the dying piglet. Use the smell of iodine to stimulate life. D. Smoke smoke: The use of tobacco cigarettes, preferably smoky tobacco smoke, is a good way to suck smoke into the nostrils of the dying piglet. Smoke irritations can also sometimes produce good results. 4. Execution of excess piglets: The so-called extra piglets are surplus piglets that have more litters than the number of teats. In the event that the excess piglets do not find foster care, the weak piglets can be killed, the crude bones can be smashed and chopped, and the pots can be boiled. Even the meat can be fed to the sows in batches to relieve the troubles of the excess piglets. Increase sow's milk production. Sixth, the health care of suckling piglets, anti-anemia piglets most likely to suffer from iron deficiency anemia after birth, should be preventive. The simpler control method is on the third day after the piglet is born. After 2 weeks of age, it is injected once again with the same dose to prevent anemia and stimulate the growth of piglets. 2. The second disease prevention is the yellow and white disease of piglets. The second disease is a common disease in sow breeding farms, with many diseases. It is usually the law of the white disease after the yellow disease exists, improper control, often lead to batch deaths, immortal often form a small stiff pigs, resulting in economic losses. Wong Nao occurs in piglets aged 1 to 7 days, and white disease often occurs after 2 weeks. There are three causes of the pathogenesis of WKD. One is cold, the second is indigestion, and the third is E. coli. Prevention and control should be based on these three reasons, take the most effective measures to prevent, the most effective drug treatment, to minimize the losses caused by yellow and white disease. 3. Prevention of epidemic diseases by epidemics refers specifically to immunization. Keepers should be responsible for their own, but also a sense of high responsibility for the user, the society, in strict accordance with the epidemic prevention procedures, timely and accurate immunization issues to stay or sell.
In fact, this is a botanical product that can replace cigarettes. As everyone knows, traditional cigarettes can cause a lot of harm to people's health, such as lung cancer, high blood pressure, cardiovascular and cerebrovascular diseases. With the development of the times, people's understanding of health has become more and more profound, and more and more attention is paid to their own health. Therefore, traditional cigarettes have been abandoned by more people, replaced by electronic cigarettes, and technologies that do not burn. Healcier was born like this. Compared with ordinary electronic cigarettes, it is more friendly to human health, so more people are turning to this revolutionary product.
