It may be that the pig has gasp disease.
Pig gastroenterosis, also known as swine local epidemic pneumonia, swine mildew psoriasis, is a chronic respiratory contact infection. Cough and gasp are the main symptoms. The disease is currently occurring in pigs of various breeds, genders, and ages, but suckling piglets, newly weaned piglets, and sows in late pregnancy and lactation are more likely to occur. Adult pigs are mostly chronically infected.
The main source of infection for swine gasping disease is sick pigs and latent infected pigs. Pathogens persist in the respiratory tract and secretions of sick pigs, and are excreted with cough and gasps and passed on to healthy pigs. This disease is most likely to occur when the house is wet, poorly ventilated, and crowded with pigs. Once the disease occurs on the farm, it is difficult to eliminate it, it can occur all year round, and it is more common in winter and spring. When the climate changes suddenly, the cold is cold, the feeding management and the sanitary conditions are poor, the condition can be aggravated.
Symptoms: The incubation period is 1-3 days, and many months. The main symptoms are coughing and gasping. In the early stage, the body temperature, appetite and spirit of the diseased pigs did not change greatly.
1. The main symptom of early onset (especially piglets) is cough. It usually occurs in the morning or evening when eating or exercising or when the weather changes suddenly. It is more likely to appear when cold air is stimulated or driven or fed. Mostly a single dry cough, while a small amount of sticky nasal fluid or purulent nasal fluid. As the condition worsens, the cough is also more intense, and the number of times increases, turning into a multiple-sound wet cough. The sick pig stands still when coughing, arches the back of the neck, and the head hangs down to the grounding surface until the secretion of the respiratory tract coughs up or swallows.
2. In the middle of the disease, the sick pig gasps, the abdominal wall is rhythmically fanned, the number of breaths is 40-70 times per minute, and the late reaches 100 times, more piglets.
3. In the later stage, the gasping is aggravated, the sick pigs have shortness of breath, and the number of breathing increases. The sick pig is sitting in a dog's posture, breathing at mouth, his expression is very painful, and the cough is long and weak. It seems that secretions block the respiratory tract, it is difficult to cough up, the nose is thick, the mouth is foamy, and the appetite is reduced.
Control method:
1. Hulunfen can effectively prevent and treat swine gasping disease. The method of use is: after weaning, the piglets are used with 40-50ppm of the mixture for 2-4 weeks; the growing and finishing pigs are used for 20-50ppm of the mixture for 2-4 weeks; Pigs can be used continuously for 3 to 50 days before and 3 days after delivery, and within 1 week after weaning; when the disease disappears, consolidate medication for 2-5 days.
2, strengthen feeding management, pig house should be clean and dry, well ventilated, control the temperature of the pig house, cold and warm.
3, vaccination, there are two kinds of porcine gastroenterology vaccines in the old epidemic areas. One is porcine gasping disease, freeze-dried rabbit attenuated vaccine, mainly used in infected areas, and the other is 168 strains of attenuated bacterin in pig gastroenterology. For hybrid pigs, use the method according to the instructions.
