1. Breeding varieties resistant to leg and foot disease
Through the selection of the degree of firmness of the limbs, the structure of the limbs is improved, and the whole body shape is changed, thereby increasing the possibility of preventing the occurrence of the disease. If the body is too large, the limbs are too slender, and the weight per unit area supporting the bone is too large, and individuals who are likely to cause damage to the feet and hooves should be resolutely eliminated and not used.
2. Improve feed nutrition
A balanced feed ensures the supply of minerals, vitamins, especially biotin, and linoleic acid. It is necessary to ensure sufficient supply of calcium and phosphorus and an appropriate ratio, and to ensure the supply of trace elements such as zinc, copper, selenium and manganese.
3. Improve the texture and management of the circle structure
The concrete floor should maintain proper smoothness and inclination (but must be less than 3°). The ground has no sharp objects and no water. It is best to use epoxy resin slatted floor on the ground of intensive pig farm. The pig pen of new cement floor must be washed several times with the plague solution, and then dried to grow pigs to avoid cracking hoof due to alkaline corrosion of pig's trotters. Conditional pig farms should ensure that pigs have a certain amount of outdoor exercise for a certain period of time, accepting sunlight, which is conducive to the synthesis of vitamin D.
4. Prevent secondary infections
In the entrance and exit of the sports field, a foot bath is set up, and 0.1%-0.2% formalin solution is placed in the pool to prevent and treat the affected pigs. The pigs that have occurred or have just had a cracked hoof have been treated by disinfection, due to hoof cracking, hoof wear and the like. Infection, swollen limbs and hoofs, compound ampicillin injection, injection of penicillin sodium, fish fat and other drugs for symptomatic treatment.
