Sterile pig breeds are degraded, and sows have a long service life, premature breeding or inbreeding, which can easily lead to piglets born with underdevelopment, low body weight, poor viability, and slow growth, resulting in fetal rigidity. Prevention: Good male and female sows are selected as breeding pigs to prevent the mating and breeding of close relatives, eliminate older females and sows, and avoid early mating of gilts. Give pregnant sows full-rate balanced feed, regularly add appropriate amount of cod liver oil, trace elements, bone powder and various vitamins to feed to meet the normal nutritional needs of the embryo. Poorly fed sows are not properly managed and fed during pregnancy or after giving birth to feeds with low nutritional value, or the sow suffers from a disease that causes postpartum milklessness or lack of milk, resulting in the piglets not eating enough milk or being fed and growing. Development is hindered and milk stiffness develops. Prevention: After sows should be postpartum nutrition, more feed concentrates and vitamin-rich feed. Sows do not eat after giving birth should be treated with antibiotics in time, and timely rehydration in severe cases. The sow-free sow is promptly galvanized and the sows suffering from mastitis are promptly treated. The sows with more litters can substitute part of the sows for the sows that have fewer litters at the same time to breastfeed. Weaning pigs after weaning are treated improperly, weaned (column), vaccine immunization, castration, etc. at the same time, which results in excessive stimulation of the piglets, much feeding of coarse material after weaning, and less feeding of concentrates, especially protein concentrates. Feeding was poor; grouping after weaning was unreasonable, resulting in bullying and bullying; or premature weaning and lack of insulation measures in winter to form stiff pigs. Prevention: Weaned piglets require a variety of feed types, with fine, coarse, and blue feeds, or feeding the full price of milking pigs, and feeding them 4 to 5 times a day. Can also be used 2% calcium carbonate, 1% sodium chloride, 50 grams of ferrous sulfate, vitamin B35 mg mix well fed 5 times a day, each feeding 1 time. Long-term sick piglets become ill for a long time or there are parasites in the body and outside, so that piglets consume large amounts of nutrients, affecting growth and development and the formation of sickness. Prevention: Improve feeding management, sick pigs alone feeding, symptomatic treatment. Piglets with yellow and white diarrhea can use lactase 2 tablets, multidimensional glucose 5 g, 0.9% sodium chloride 50 ml, and complex vitamin B 10 ml orally for 2 to 3 days. Insect zombies due to parasitic parasites in vivo, so that the piglets nutrient consumption, affecting the growth and development of the formation of stiff pigs. Prevention: The first to pick out the pigs were kept alone, parasites inside and outside the parasite susceptible to chronic enteritis, should start from the deworming and stomach. (1) Deworming. With the refined trichlorfon, according to 0.1 ~ 0.15 g / kg body weight 2 days of abdominal feeding or use the star eight plus two, pest control Wei insect repellent. (2) appetizers. Available Strychnosozycin 2 ~ 3 ml, artificial salt 25 grams, rhubarb soda 0.6 g once orally, used 2 to 3 times a day. (3) The ectoparasite can be purified by adding 8 grams of purified trichlorfon to water and spray on the body surface once a day for 3 to 4 days. (4) Strengthen feeding and management, feed compound feed or concentrate feed, add appropriate amount of salt, bone powder, trace elements, etc., and feed it once a night at night. After weaning weaned piglets, the quality of the diet is poor, nutrition is lacking, or the piglets are raised in the same group. The strong ones eat more food. The weak will not eat enough feed and become hungry. As time passes, stiff pigs will form. Prevention and control: Feed the separated feeders of the weaned piglets so that each piglet can feed, or feed them separately according to the strength of the piglets, so as to ensure the uniform growth of the piglets and avoid the production of stiff pigs.
