Respiratory diseases have long been troubled by farmers. Why is there a frequent occurrence of porcine respiratory diseases in clinical practice but it is not completely cured? The main reason for this is the mixed infection of respiratory diseases, incorrect treatment plans, improper farm management, and improper health care. Once a respiratory disease occurs in a pig farm, how to conduct timely and effective treatment and treatment, Beijing Huaxia Kangyuan Technology Co., Ltd. suggests that we can start from the following three parts: 【More Related Technical Issues】

First, correctly determine the types of respiratory diseases Simple symptoms of respiratory diseases are: cough, dyspnea, loss of appetite, feed utilization, reduced growth rate, the overall mortality rate is not high, but seriously affected the farm economic efficiency. Mixed infections of respiratory diseases are mostly caused by mixed infections of Mycoplasma pneumoniae, blue ear virus, type II circovirus, and parasites. Clinical symptoms include acute abdominal breathing, high difficulty in breathing, persistent fever, and rapid feed intake. Decline, some even refuse to eat, and the death rate is extremely high.

Second, find out the cause of respiratory disease
1. Infectious Diseases When a disease epidemic breaks out, a large number of bacteria and viruses will grow in the pig houses. When the body resistance of pigs declines, the pathogens of endogenous infections are activated, causing the outbreak of respiratory diseases, and the introduction of breeding pigs or piglets, not Isolation or isolation time is insufficient, pathogens are not completely purified and cause respiratory diseases.

2. Feeding and management factors During the high incidence of respiratory diseases, some pig farms adopt dry feed methods, resulting in more dust in the pig houses, high feed density, and poor ventilation, resulting in ammonia and carbon dioxide concentrations in the pig house. high. When the concentration of ammonia gas in the pig house is more than 50ppm and the carbon dioxide content is more than 0.2%, respiratory mucosal damage and harmful components in the blood can be increased, causing inflammation of the respiratory tract, especially in the late autumn and winter and spring when respiratory diseases are high.

3. Pathogenic bacteria caused by pathogen infections mainly include mycoplasma pneumonia, contagious pleuropneumonia, Haemophilus parasuis, atrophic rhinitis, and swine plague. Almost 80% of swine farms have mycoplasma pneumonia and are the most common respiratory diseases (asthma), which are common during weaning, nursery and fattening.

4. Viral infections are mainly porcine reproductive and respiratory syndrome, pseudorabies and swine flu. In the delivery room piglets and nursery pigs, the respiratory tract caused by PRRS is the most obvious; circovirus type II infection can cause pneumonia in nursery pigs; swine flu is common in seasons where temperature changes are more severe, spreads rapidly, and has a short duration.

5. Parasitic infestations are mainly respiratory diseases caused by porcine larvae, posterior roundworms, lungworm larvae, or adults parasitizing pig bronchi and bronchioles. Eggs can be detected in pig feces before death and diagnosed after death in the trachea, lungs, and intestinal tract.

Third, develop reasonable and effective health care prevention and treatment programs

1. Formulate a rational vaccine immunization program to develop immunization programs in strict accordance with the national standard immunization procedures and the actual situation of the farm (epidemic prevalence). Piglet 7-day-old and 21-day-old immunization against inactivated vaccine, 25-day-old immunization Blue-ear disease inactivated vaccine, 35-day-old immunized swine pneumoconiosis-porcine erysipelas double vaccine; 55-day-old inactivated atrophic rhinitis inactivated vaccine. For some vaccines, the immune stress is large and the immune effect is not good. Green leaf health pigs are recommended to add 0.5% Chong Yi No. 1 in the feed for 10 days before and after the immunization of the swine herds, effectively eliminate the immune stress, prevent the immune failure, and enhance the vaccine immunity. effect.

2. Improve the body resistance of pigs to prevent respiratory tract infections. Green leaf health pigs are recommended to add 0.5% Odemann A to pig diets during the high incidence of respiratory diseases to effectively enhance herd non-specific resistance to disease, especially against the virus. The ability of sexual diseases to significantly increase the level of lysozyme in the body and prevent the infection of pathogenic microorganisms.

3, do a good job of daily feeding and management work in the high incidence of respiratory diseases, try to reduce the pighouse dust, reduce the ammonia concentration of the livestock, dry material for the wet material, the piggery window is always open, if the winter and spring is more cold, it should be at noon Within two hours, open the south and north windows for ventilation. Green leaf health pigs are recommended to spray the nursing house 1-2 times per week in the piggery, and 100-200 square meters of piggery can be sprayed in each nursing house to effectively remove ammonia and deodorize and suppress the harmful bacteria in the pig house. Proliferates and reduces the incidence of respiratory diseases.

4. The three stages of 45-day-old pigs for repelling piglets in time, 90 days for shelf pigs and 135 days for finishing pigs are the susceptibility periods of the parasites. It is possible to mix avermectin or ivermectin in the feed. Deworming. Sows can be fed with avermectin or ivermectin for 4 months or 2 weeks prior to delivery to prevent insects from infecting the fetus. The gilts can be fed with avermectin or ivermectin for one month before the breeding to repel insects, effectively preventing parasite-induced respiratory diseases.
