Rickets is a common and frequently-occurring disease in pigs. In large-scale pig farms, the infection rate of pigs is high and there is a trend of increasing year by year. Let's take a look at the prevention and control measures for swine fever.
First, the cause of the disease
1. Pig mites are dark and damp, such as in the rainy and continuous season, in dense pigs and poor sanitation conditions, which is conducive to the reproduction, spread and spread of mites, and the performance of infected pigs is also more serious. The use of wet curtains, if the ventilation is poor, wet and dirty, also created conditions for the breeding of cockroaches.
2. Regardless of the size of the pig, it can infect ticks, but the piglets are more susceptible, the symptoms are more obvious, and the harm is also greater. As the age increases, the symptoms gradually decrease and become a sputum. The disease is often caused by the worm. Passed to piglets, therefore, the prevention and treatment of sows has been paid attention to, but it is not known that boars are also common, and some farms ignore the prevention and treatment of boar rickets, and unwittingly give this disease to pigs. The long-term popularity of the field has buried the bane.
Second, the symptoms of the disease
More than 5 months old. The skin of the sick pig is itchy, and the lesion often starts from the head, such as around the eyes and ears, and then spreads to the back, the sides of the trunk and the limbs. Due to the mechanical stimulation and toxin action of the aphids, the pigs are severely itchy, rubbing in the column, corners, troughs, stones, etc. The hair of the affected part is shed, the skin becomes thick, dry, with dander, and forms pleats and cracks. When the course of the disease is prolonged and the condition is severe, the appetite is reduced, the spirit is weak, the skin is getting thinner, the growth is slow or stagnant, anemia, and even death.
Third, treatment measures
1.2%~4% trichlorfon solution (take 100 parts of warm water, add 2~4 parts of trichlorfon), directly rub, spray or medicate bath, once a week, after 2~3 times, it has good effect.
2. 50 grams of sulfur, cottonseed oil or peanut oil or 500 ml of soybean oil, first boil the cottonseed oil, add sulfur later, stir well and apply the affected part.
3. Tobacco water: use 1 part of tobacco leaves or stems, add 20 parts of water, cook for 1 hour, filter and apply to the affected part.
4. Waste oil is applied to the affected part once a day.
Fourth, preventive measures:
The pig house is kept clean and dry, and the pig house is usually disinfected with 20% lime water and 4% trichlorfon. Sick pigs should be isolated and treated immediately to prevent spread; prevent the purchase of sick pigs from outside; sick pig houses and feeding management equipment should be thoroughly disinfected with disinfectant such as 2% caustic soda or 10%~20% lime water.
The above are preventive measures and treatment measures for swine fever. The hidden loss caused by rickets in pig farms can not be underestimated. It is best to prevent rickets.
