Respiratory disease is a common disease, frequently-occurring disease, the main lesion in the trachea, bronchi, lung and chest, lesions are more cough, chest pain, respiratory effects, severe breathing difficulties, hypoxia, and even respiratory failure and death. Due to air pollution, smoking and other factors, The chronic obstructive pulmonary disease is increasing including chronic bronchitis, emphysema, pulmonary heart disease, bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, and pulmonary infection the morbidity and mortality of the disease at home and abroad . Therefore, anti-respiratory disease drugs are also more and more attention paid by researchers. Respiratory disease have the symptoms of cough, sputum, hemoptysis, chest pain, shortness of breath and other symptoms of lack of specificity, often clinicians mistaken by people for colds, bronchitis, and severe pneumonia, tuberculosis or lung cancer and other diseases delayed diagnosis; Respiratory tract infection, to be developed to emphysema, pulmonary heart disease, respiratory failure was taken seriously, but it was too late, its pathology and physiological function has been difficult to reverse. As with other systemic diseases, careful and detailed medical history and physical examination are the basis for the diagnosis of respiratory diseases, and should be combined with routine laboratory tests and other special findings to conduct a comprehensive and comprehensive analysis. Currently the most clinical application of anti-respiratory disease drugs have the following four categories: 1. Antihistamines 2. Cough medicine 3. Bronchodilator 4. Expectorant 5. Anti-asthma drugs.

Fish pond net meat duck technology
The traditional ducklings on the water surface not only pollute the water quality, but also the meat ducks consume too much energy on the water surface, which is not conducive to rapid growth. The use of fish ponds and surface nets to raise meat ducks can overcome the above-mentioned drawbacks. The method is simple and easy to implement. It not only benefits the ecological balance, but also raises the economic benefits of raising meat ducks. It can also directly use duck dung to fish, and it serves two purposes. The technical points are as follows. 1. Build a bamboo house. Set up a bamboo house on the side of the fish pond. Half of it is built on the fish pond. Half of it is built on the shore. A bamboo strip is set at a height of 40 to 50 cm above the ground. The bamboo strip is covered with a bamboo strip spacing of 10 centimeters above the bamboo strip. Nylon woven mesh. This will not only help the duck to walk on the bamboo but also prevent the meat duck from being affected by the trauma and affecting the market quality. The bamboo floor is covered with straw, which can keep the wind warm and install a window with adjustable air volume. Furrows and sinks are placed under the sink to prevent feed wastage. Fluorescent lamps are installed in bamboo buildings for evening lighting. 2. For drinking enough water. A simple water tower is placed outside the bamboo house, and 3 tons of water can be poured in each time. A simple water pump is installed and the water is pushed into the water tank through the water pipe. The sink can be made of bamboo or rough plastic pipes, with drinking water holes above it and water in the tank for continuous supply of clean drinking water. 3. Feed requirements. Use rice, broken rice, rice bran, sorghum, corn, etc., varieties should be diversified, and feed more green feed. The diet contains 14% crude protein and 12.13 MJ/kg of metabolizable energy. Add 10% of sand to aid digestion. 4. Add night food. Feed each time in the morning and evening and feed once a night. Feeding is unlimited. 5. Suitable density. The duck dung that is leaked into the water contains 30% of undigested nutrients, which can be used as fish feed, and can reproduce plankton, forming a good ecological cycle. Ducks are stocked with 80 to 100 eggs per 667 square meters of water. 6. Do a good job of prevention. Ducks have high densities and need to prevent diseases. Nylon woven mesh and bamboo pieces should be disinfected regularly, and the sink should be washed twice a day. 7. Timely travel. 20 days before the sale of meat ducks should be given 10 minutes each time. Keep the duck feathers white. 8. Timely listing. When the survival rate of fish ponds and duck nets exceeds 95% and the body weight reaches 2.5 kg, the rearing period can be shortened by 43 days compared with conventional breeding, and timely sales are required.
