First, do a good job of production. When the sow is in litter, the breeder must be present. After birth, the piglet should be wiped with a towel to remove mucus from the nasal mucous membrane and its front tires in order to allow it to breathe normally. Then wipe the entire body, and then place it at a distance of 5 cm to 7 cm from the piglet's umbilicus. Centimeter (can not be too short or easy to bleed) at the Department of the umbilical cord cut off by hand, apply iodine tincture, cut off the four piglets teeth, and in the tail from the tail three centimeters after the end of the incubator. For dying piglets, the piglet can be turned head down, holding the pig's two forelimb ribs with both hands, and squeezing it one by one until the piglet makes a sound. Another way is to keep the pig's limbs up, one hand on the shoulder of the piglet, the other hand on the piglet's buttocks, and the two hands repeatedly flex the body of the piglet until the piglets make a sound. You can also take the first aid by rubbing the nose with alcohol or other stimulatory piglets or acupuncture.
Second, eat enough colostrum. Colostrum is crucial for disease resistance, disease prevention and survival of piglets. After birth, piglets should be allowed to eat colostrum as soon as possible, preferably within 2 hours. Colostrum is the milk within 3 days of the piglet's birth. Colostrum contains a lot of immunoglobulins and disease-resistant factors, which can improve the immunity and disease resistance of piglets. It is an indispensable food for newborn piglets. Piglets that do not eat colostrum are very Hard to survive. Artificial supplements should be given to weak piglets to increase physical strength, restore body temperature, and replenish moisture.
Third, fixed teats. When piglets start to feed after they are born, they often compete with each other for nipples, which may result in weaker piglets not eating milk. Therefore, the nipples should be fixed after birth. Fixed nipples should adhere to the principle of “mainly self-selected, appropriate adjustment, and controlling strong and weakâ€. The method is: let the piglets choose their own nipples first, and then adjust them according to the size of the body and the physical strength. Generally, the weak piglets are fixed on the sows. The middle front nipple sucks the milk, and it is firmly fixed in the back so that the litter of the litter can grow neatly without stiff pigs, and the piglets can avoid nipping the nipple in order to compete for nipples.
Fourth, pay attention to insulation, cold. The function of the newborn piglet to regulate body temperature is not perfect, its ability to regulate the ambient temperature is very low, especially its ability to withstand cold stress is poor. The temperature of the delivery room is maintained at 20°C or higher. The optimum temperature for newborn piglets is: 1 day to 3 days old 30°C to 32°C, 4 days to 7 days 28°C to 30°C, 8 days to 14 days old 25 °C ~ 28 °C, 15 days old to split litter maintained at 25 °C, winter and spring seasons should pay special attention to cold, warm, sows before littering, litter box should reach the required temperature of about 32 °C, so that the piglets have a comfortable temperature surroundings. Piglets are difficult to survive at low temperatures and can easily cause diarrhea, which can affect growth and development.
Fifth, to prevent death. Within one week after birth, the piglets are of weak constitution, weakness in limbs, inflexible action, incompatibility with the external environment, like to be close to the sows or into the bedding, and the sows are post-partum fatigued, the action is slow, and the piglets are easily beaten or crushed . So it is best to have a sow and piglet fence.
Sixth, early feeding and replenishment. At the age of 7 to 10 days, put a little fresh and clean pig farm material into the feed tank of the piglet to attract food, and put the piglet on clean ground to allow the piglet to imitate sow feeding and feeding. The amount should be as low as possible, and it is guaranteed that the piglets are fresh every day. Piglets need to drink water after breastfeeding. If they do not find clean water, they will drink dirty water or urine and are prone to diarrhea. Therefore, the piglets should drink clean water in time. Early drinking of water not only helps digestion but also prevents diarrhea. It can also make the piglets spirited and bright red skin. Pay attention not to change feed formulas and feed locations at the time of feeding, and to add less ground when feeding.
7. Observe carefully. Within five days of the birth of the piglet, special nurses should be on duty in rotation to observe the growth, feeding, feeding, and droppings of piglets at any time. If piglets are found to be thin, they must be supplemented with appropriate concentrates to find that the piglets are diarrhea or do not eat. For diagnosis and treatment, the number of piglets should also be carefully counted so as to prevent the sow from squeezing the piglets.
Eighth, prevention of disease. The first thing is to prevent the epidemic After the piglet has processed the umbilical cord and dried the mucus, it is injected intramuscularly with a single dose of swine fever, 1 dose (150 immuno units), and colostrum is given 1-2 hours later. The second is to prevent anemia. Iron and selenium can be supplemented in time, with 2 ml of iron dextran or 100 mg of dextran iron injection, intramuscularly once at 3 days of age, and once at 2 weeks of age. Third, we must prevent squatting. First of all, sows are injected with yellow and white piglets multi-valent seedlings 15 days prior to sow's birth; followed by keeping the pens clean and sanitized and often disinfected to prevent piglets from drinking filthy water. Fourth, prevention of postpartum diseases in sows. Observe the sow’s breathing, body temperature, feces, and breasts in a timely manner to prevent postpartum disease and affect lactation and piglet growth. Five must be disinfected. Each month, 100 pig poisons and 1210 disinfectants are used to cross-sterilize pig houses and utensils.
Nine, cut off milk. The timely weaning of piglets is the main measure to ensure the normal production of sows. The pig production is mostly weaned at 4 to 5 weeks of age. Usually, weaning can be done after 30 days of age, but it must be based on the pig's diet, climate, and material type. Sows have milk conditions that are flexible and weaned, such as early weaning, early weaning, appropriate weaning (around 28 days), winter weaning as much as possible (around 35 days), and sows not being weaned before sow lactation peak (sow till 26 Days are limited. Weaned sows should be promptly weaned. Because the piglets are faced with both nutrition and digestive stress during weaning, the weaning transition is not good, and the piglets are often prone to reduced appetite, diarrhea, reduced weight gain, and even death. It is best to adopt the method of weaning without weaning and try to ensure that the feed, environment, and management are the same, so as to prevent the piglets from undergoing stress responses. The management, environment, and feed should be gradually improved so that the piglets have an adaptation process.
Surfactants, known as "industrial monosodium glutamate", refer to substances with fixed hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and make the surface tension decrease significantly. Surfactants are generally organic amphoteric molecules with hydrophilic and hydrophobic groups, which are soluble in organic and aqueous solutions. Hydrophilic groups are often polar groups, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amino groups and their salts, but also hydroxyl, amide, ether bonds; hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than eight carbon atoms. Surfactants are classified into anionic surfactants (mainly soaps, sulfates, sulfonates), cationic surfactants (also known as quaternary amines), amphoteric surfactants and non-ionic surfactants (mainly including fatty acid sorbitans, polysorbates, polyoxyethylene fatty acid esters) Polyoxyethylene fatty acid ether, etc.)
