How to raise wild boar well

1. Enclosure design: sub-nest room and outer nest room. The Liwo room is a place for "wild boar" to eat and sleep, with an area of about 3.5 meters long and 2.5 meters wide. The outer chamber is a place for exercise, sun exposure and drinking water, with a drinking sink 1.5 times the size of the chamber. The inner and outer chambers are paved with cement and sand oars, but not too smooth and slightly sloping, so as to urinate and wash, and keep the enclosure dry and clean. The difference between a wild boar and a pigsty is to build a passage 1.2 meters away from the outer nest so that the breeding boar can enter the enclosure of any sow that has been in estrus, and then return to the original nest for breeding through the passage. 2. Feed formula: corn meal 22%, wheat bran 30%, soybean dregs or a little soybean 5%, Panax notoginseng bran 22%, green feed 20%. Plus, 15-40 grams of amino acids (each head per day), 0.5% iodized salt, 0.5% bone meal. 3. Prevention and treatment of main diseases: (1) Prevention and treatment of classical swine fever: anti-classical swine fever serum is injected intramuscularly with 5ml twice a day for 3-4 days, and a large dose (230-50 doses) can be used, and the attenuated classical swine fever vaccine can be injected subcutaneously once. (2) Prevention and treatment of porcine lung vaccine: penicillin 1.8 million × 2 (less than 75 kg body weight) was injected intramuscularly, and then ofloxacin 5ml × 2 was injected twice a day for three days. (3) Prevention and treatment of porcine erysipelas: the disease is also known as "fire imprint". In terms of prevention and treatment, penicillin can be injected deep into the muscle according to 40,000 units per kilogram of body weight, twice a day for 3-5 days, and wipe the pig body with strong soapy water to cover the pig body with soap bubble, which is very effective. Main points of feeding and management of breeder sows ① feed quantity: daily feed quantity is between 2.5kg-3.0kg, feeding 3Mel 4 times a day. ② estrus: estrus is usually about 7 days after weaning. Each estrus cycle is between 18 and 24 days, and the duration of estrus is 48 Mel 72 hours. The obvious symptom of estrus is 24 hours after estrus. The vulva of the sow is swollen, sometimes a small amount of mucus flows out, willing to approach the boar, accept the boar to climb across, and lose appetite. ③ mating: under normal conditions, sows are normally in estrus 17 days after weaning. When the age of reserve sows should be 10-14 months, the body weight of reserve pigs should be 65ml. 75kg reserve pigs should be mated prematurely, which will not only affect their head reproduction performance, but also affect their development and reduce their lifetime reproductive performance. Too late mating will increase the breeding cost and affect the lactation after litter production. After the female wild boar reaches sexual maturity, there is an inherent sexual cycle, also known as the estrous cycle (usually, the interval between the last estrus and the next estrus is called the estrous cycle). The estrus of purebred wild sows twice a year in spring and autumn belongs to seasonal estrus; the average estrous cycle of domesticated wild sows is 20 days, and the range of estrus is 24 days, and the estrus lasts 5 days, which is divided into three stages: before, during and after estrus. The suitable time for mating is in mid-estrus, that is, 24 hours after sows show symptoms of estrus, as long as they are willing to accept the boar to climb across, they can mate for the first time. After the first mating, it was mated for the second time in 24 hours with 18Mel. Generally, you can mate twice in one estrous cycle. More mating can not increase the litter size, or even have side effects. The key is to master the appropriate time for mating. Key points of feeding and management of breeding boars the first mating age of breeding boars is 12 Mel 14 months old. The most suitable body weight for the first mating is between 65ml and 75kg, and it is not suitable for breeding if it is too thin or too fat. The service life of the breeding boar is less than 4 years, and the breeding boar is raised in a single circle. ① feed: adult boars feed 2.5kg-3.0kg per day, 2Mel three times a day, and feed with the ratio of water to feed at 1:2 (that is, 1 part of water, 2 parts of feed, mix evenly). ② exercise: because breeding boars are raised in a single circle, in order to strengthen sperm activity, they should go to the playground more than twice a week, each exercise time should not be less than 4 hours, and the exercise distance should not be less than 1.5km. Usually pay attention to wash the pig body and keep it clean. ③ breeding: it is appropriate to breed once a day, no more than 2 times a day. After continuous breeding for 5 days, rest for 1 day. During the peak breeding season, proper amount of green fodder or carrots should be added to the feed, and an egg should be fed for three days if possible. Keep the piggery warm in winter and prevent heat in summer to prevent mixing with other kinds of boars. ④ automatic drinking water: automatic drinking fountain is installed in the house. Sow production and postpartum management the expected delivery period of pregnant sows is generally 116 days ±5 days. The calculation method is as follows: monthly plus 3 of the last mating date, and daily plus 24 is the expected delivery period. (for example, January + March April, 5th + 24029, that is, the expected date of delivery is April 29th, 2004). The sow was transferred to the delivery room on the 10th day of prenatal delivery. Immediately after giving birth, take out the mucus from the mouth with your hands, then close it with a clean, soft cloth or hay and carefully wipe the mucus all over the body, immediately send it to the incubator, wipe your nose with 75% alcohol for piglets with weak breath, and gently pat your chest with your hands until your breathing is normal. After giving birth, squeeze the blood in the umbilical cord to the inside as much as possible, then press it with your fingers to prevent blood reflux, disconnect the umbilical cord 3 cm from the abdomen for 3 minutes and disinfect it with 5% iodine tincture. Such as bleeding can be ligated to stop bleeding. During the first lactation, the large and strong ones should be fixed on the rear nipples of the sows, so that the piglets can develop evenly. Generally, the piglets can be breastfed 1 hour after the placenta is excluded or the last piglets are born. Artificial midwifery or surgery should be performed if the stage of labor is more than 8 hours. Postpartum management feed restriction management: postpartum sows fed only soybean meal and bran soup for 10 hours after delivery. Postpartum 2Mel 3 days can not give too much feed, less roughage, feed some nutritious and digestible feed, postpartum 5 days can return to normal feeding. 20 days after delivery, the daily feed dose was 4 kg at 3 Mel, and the daily feed dosage at 21 Mel was 5 kg at 30 days, and changed to normal dosage at 31 days after delivery, with a daily dose of 2.5 kg. Feed three times a day. Control drinking water in the first 2 days after delivery, and ensure adequate drinking water later. Special care: sows with no milk or insufficient milk after delivery can be fed some highly nutritious foods such as soybean milk, Millet Congee, placenta soup, fish soup and so on. Sows with postpartum constipation symptoms can be supplemented with some tender feed, serious can use some laxatives, until normal. In the feeding and management of the whole lactation period, attention should be paid to ensuring air circulation, fresh air, maintaining hygiene, preventing moisture and keeping the enclosure dry. Management of ① newborn piglets during lactation: due to the poor resistance of newborn piglets, heat preservation must be done. The injection temperature should be kept between 25 degrees Celsius to 30 degrees Celsius at the age of 1-7 months and 20 degrees Celsius to 25 degrees Celsius at the age of 8-30 degrees Celsius. Over 40 days old and above 18 degrees Celsius, too low temperature and too much humidity will cause a variety of diseases and affect the survival rate of piglets. ② eat full colostrum: because colostrum contains maternal special antigen, enough colostrum can promote the growth and development of piglets, so it is necessary to ensure that each piglet eats full colostrum, and it is best to artificially fix nipple feeding according to piglet size to ensure the balanced development of piglets.
