Prevention techniques of stiff pigs

There are many reasons for the formation of stiff pigs, including congenital factors such as inbreeding or early mating and improper feeding and management of pregnant sows, resulting in low birth weight and weak vitality of piglets, as well as acquired factors. such as sow milk deficiency, malnutrition, early weaning, untimely feeding, serious lack of nutrition and disease and other factors. The following measures can be taken to relieve stiffness and fattening.

㈠ repels worms and clears the stomach. When there is no disease and the weather is fine, stop feeding at noon and feed it once with an empty stomach at 8-9 o'clock in the evening, according to 15-20 mg of imidazole or levamisole per kg of body, mixed with a small amount of concentrate. Two days later, 1 kg of quicklime was dissolved in 5 kg of water. After precipitation, the limewater solution was mixed and fed to pigs, once a day for 3 days. For stiff pigs in good condition, you can also stop feeding once and only feed 0.9% light saline or a small amount of laxative, such as artificial salt, mirabilite, etc., to remove various toxins in the gastrointestinal tract of stiff pigs that restrict the growth and development of stiff pigs.

㈡ invigorates stomach and dissolves food. It is necessary to make a big change in the digestive function of a stiff pig in order to get rid of it completely. According to the body weight of stiff pigs, you can use 1 tablet of rhubarb soda (0.3 grams) per kilogram of body weight, no more than 10 tablets, and feed the final mixed feed twice a day for 3 days to strengthen the stomach. at the same time, 50 grams of Hawthorn, malt and Shenqu were used in combination with 50 grams of Hawthorn, malt and Shenqu for 5 days. Practice has proved that the stiff pigs treated in this way have a strong appetite and their digestive function is greatly enhanced.

㈢ fine-nourished tube. Green fodder should be washed and drained, properly chopped, and coarse materials such as bran should be processed and crushed before raw feed with more comprehensive nutrition can be mixed in proportion, and 0.5% oxytetracycline powder can be added to the formula feed to enhance the disease resistance of stiff pigs.

㈣ is fed with "stone sulfide". The same amount of quicklime, sulfur and salt, first stir-fry the salt, pour in quicklime and stir-fry for 10 minutes, put into the pot to cool, add sulfur, research together, bottle and set aside. Pigs weighing less than 25 kilograms take 5-8 grams per day, and pigs weighing more than 25 kilograms take 10-15 grams daily until they get fat. This not only supplements minerals, but also stimulates appetite, which is an indispensable important measure for fattening stiff pigs.

㈤ was injected with vitamin B12 intramuscularly. After 10 days of deworming and clearing stomach, each pig was injected with 2-4 ml of human vitamin B12 every 3 days (sold in various pharmacies) for 7-10 times in a row, which has a special effect on promoting growth and strengthening physique. In addition, it should be kept clean, ventilated and ventilated. After the condition of the stiff pig improves, hit the "triple vaccine" to prevent classical swine fever, swine erysipelas and porcine lung disease in time.
