Greedy, no disease, no parasites, just hungry for 2 ~ 3 days, just to drink water and stomach medicine. When the food was reopened, the pigs were hungry and ate well. Since then, strict timing and quantitative feeding, eating only 80% full at a time, so that pigs always maintain a strong appetite.
Second, nutritional therapy.
1. For stiff pigs with poor fat, strong appetite and large abdomen, wet mixing should be given to increase dry matter and nutrients in the diet. At the same time, a reasonable diet can make the diet nutritious and get rid of rigidity.
2. Pigs that are fat enough to eat will soon become stiff as long as they add cake feed (100 ~ 150g/ head/day) or fish meal (50 ~ 100g/ head/day) and other feeds containing more protein.
3. For stiff pigs suffering from milk stiffness, feed stiffness, drug damage or colds, anemia, malnutrition, weak constitution, poor fat status, rough coat, pale face and weak constitution, intramuscular injection of Angelica injection, inosine+vitamin B 12, 5 days a day, or intramuscular injection of 65438+.
Third, therapeutic therapy.
1. Rigid pigs with asthma and chronic enteritis were given oxytetracycline for prevention and treatment, and each pig was given 40 mg of kanamycin daily or intramuscular injection until they recovered.
2. Stiff pigs suffering from ascariasis and pulmonary filariasis can be fed trichlorfon at a weight of 0. 1g/kg, once a day, for 4 consecutive days, and those with mild poisoning can be injected with 1 atropine for detoxification. Trichlorfon can drive ascaris, and a large dose has a considerable effect on pulmonary filariasis. It can also excite sympathetic nerve, promote the contraction of gastrointestinal smooth muscle, regulate gastrointestinal function and enhance the appetite of stiff pigs.
3. Pigs with refractory sarcoidosis or swine lice were fed with 0. 1.4 g/kg body weight, and fed again one week later, with obvious effect. In addition, the solution of trichlorfon should be sprayed on the piggery and utensils, so as to completely eliminate the scabies and pig lice and prevent the recurrence after recovery.
Fourth, stomach strengthening therapy.
1. For stiff pigs that have been deworming several times, but have slow growth, thick hair, dry stools and good spirits, but don't eat much, add wheat bran or stomach-invigorating drugs to the complete feed every meal until the stools are loose. In the early stage, dilute feed or green juicy feed was the main feed; Increase its gastrointestinal volume; When the pig's feces are normal and the appetite is strong, use wet mixing.
2. The dead pigs that have been deworming, but have slow growth, rough hair, dry stools and good spirits but don't eat much are fed with compound artificial salt, which consists of 70% artificial salt, 20% jiao Sanxian (30% fried hawthorn, 40% fried malt and 30% fried Massa Medicata Fermentata), fish meal 10% and stomach-invigorating amount.
Five, Chinese herbal medicine therapy
All kinds of stiff pigs are caused by low metabolic function and insufficient nutrient intake. Traditional Chinese medicine for invigorating the spleen and nourishing the stomach can get rid of rigidity. Rhizoma Dioscoreae, Scutellariae Radix, Radix Angelicae Sinensis, Rhizoma Chuanxiong, Rhizoma Osmundae, Fructus Aurantii Immaturus, Cortex Magnolia Officinalis, etc. Crushing, sieving and mixing evenly, mixing for 7 days, and using for 5 days after half a month can significantly improve the weight gain speed.
Sixth, prevent the emergence of stiff pigs.
In production practice, in order to eliminate stiff pigs, we should avoid inbreeding and premature utilization of male sows, strengthen the feeding management of sows, especially pregnant sows, and do a good job in prenatal and postnatal disease prevention to prevent the occurrence of stiff pigs due to congenital factors. Secondly, according to the characteristics of piglets in different periods, we should give correct feeding management and care, and do a good job in antifreeze and heat preservation, iron supplementation, initial strain, "grasping three grains, passing three customs" and "three transitions" for weaned piglets. Third, do a good job in cleaning the pig house, prevent cold and heatstroke, and expel insects regularly to ensure the healthy growth of pigs. Adhere to autotrophic production and management and scientific feeding management, do a good job in epidemic prevention and disease removal, improve the survival rate, growth rate and feed utilization rate of piglets, and prevent the emergence of stiff pigs.
