How to use medication for chicken respiratory diseases in winter and spring? Farming experience sharing
There are many causes of chicken respiratory diseases, which can be broadly divided into non-infectious causes and infectious causes. Every year starting from Cold Dew, the temperature difference between day and night increases, and most farmers reduce ventilation time to keep warm. Coupled with factors such as unreasonable chicken coop design and unreasonable vaccine immunization, respiratory diseases have long plagued the majority of farmers. Analysis of disease causes: Feeding management - poor ventilation in chicken coops. The concentration of harmful gases such as carbon dioxide exhaled by chickens, ammonia and hydrogen sulfide produced by feces, and carbon monoxide produced by incomplete coal combustion rises, while oxygen concentration decreases. Chickens kept in such an environment for a long time will suffer damage to their respiratory systems. Ammonia and hydrogen sulfide gases can cause inflammation of the conjunctiva and tracheal mucosa of chickens, making it easy for pathogens to invade the respiratory system and cause disease; carbon monoxide can cause poisoning in chickens; dust caused by dry litter carries large amounts of pathogenic bacteria such as E. coli, and when the concentration is high or the body's resistance decreases, it is easy to cause colibacillosis; if moldy litter is used, large amounts of mold spores are dispersed in the air, and after being inhaled by chickens, they cause aspergillosis in chickens. Environmental factors such as excessive stocking density in chicken coops and ambient temperatures that are too high or too low can all interact with infectious respiratory pathogens, aggravating the symptoms of respiratory diseases.

What are the prevention and control measures for infectious bursal disease in chickens?
(1) Strengthen feeding management and hygiene measures Strengthen the feeding management of the chicken flock, maintain intervals between chick placements, implement an all-in-all-out rearing system, carry out thorough cleaning, hygiene and disinfection work, and reduce and avoid various stress factors. These general principles for preventing and controlling infectious diseases are extremely important for the prevention and control of infectious bursal disease. (2) Vaccination Through effective vaccination, the chicken flock acquires specific resistance, which is the most important measure for preventing and controlling infectious bursal disease. 1. Increase the antibody levels of breeder chickens

What disease causes geese to die quickly after passing green droppings?
Ma Yonggen from Qinxing Village, Zhenze Town, Wujiang City called to say that he had raised more than 400 geese. When the geese weighed three to four jin, he found that several geese were lying down unable to stand, passed green droppings, and died quickly. Within two days, 6 had already died, and several more geese had also shown symptoms of lying down and looked like they were failing. The local veterinarian diagnosed it as a septic infectious disease. Based on the above situation, the geese may have viral enteritis or fowl cholera. Both diseases have symptoms of passing green droppings and rapid death. Which specific disease it is should still be further diagnosed.

The previous batch of pigs had blue ear disease (porcine reproductive and respiratory syndrome). How should the pen be disinfected?
1. Cleaning and washing. Remove all contaminants and bedding from the pen, and sweep down the dust from the ceiling as well. Then pile it all together to ferment. Then rinse thoroughly with clean water. 2. Disinfection of the floor and walls. For the floor, use caustic soda or sodium hydroxide. For the walls, spray with iodine-based or chlorine-based preparations. 3. For metal equipment that is not afraid of heat but is afraid of corrosion: use a blowtorch (alcohol blowtorch, kerosene blowtorch). 4. For enclosed pens: fumigation. Peracetic acid, formaldehyde, or potassium permanganate can all be used. After sealing for 2 hours, ventilate for 7-10 days. Basically it takes half a month.

Key Technical Points for Disease Prevention and Control in Pollution-Free Fish Farming
Symbiosis of plants and animals: When aquatic plants and fish live together in the same pond, the fish rarely get sick. The aquatic plants planted in the fish pond are rice or lotus roots, arranged in an east-west direction, with wide row spacing (greater than 33 cm), occupying no more than 50% of the total water area so that the lighting effect is good. The water depth depends on the water tolerance of the aquatic plants; for rice it is generally within 30 cm, and for lotus roots it can generally reach more than 50 cm. The farmed fish can be conventional species or famous, special and improved new varieties. The farming method can be seedling breeding or adult fish farming. Because residual bait, fish feces and so on are deposited

Detailed Guide to Controlling the Three Major Diseases of Onions and Garlic
I. Purple blotch. It mainly affects chives, Welsh onions, garlic, onions, and Chinese chives, and is a major disease of Welsh onions and garlic, with leaves and flower stalks being the main affected parts. The lesions are initially water-soaked, grayish white, slightly sunken, and later expand into oval or spindle shapes, becoming purplish brown. When humidity is high, the diseased area produces black mold layers arranged in concentric rings. In severe cases, it causes leaves and stalks to die or break over. The disease occurs severely under warm, humid conditions or when there is a lack of fertilizer and drought. Fields with sandy soil, dry land, and severe thrips damage have severe disease incidence.

Symptoms and Prevention and Treatment Methods of Rheumatic Disease in Dogs
Rheumatic disease is an acute or chronic non-suppurative inflammation that often recurs; it most commonly affects the muscles, joints, and heart. It occurs relatively often in dogs. [Etiology] The cause of rheumatic disease is still unclear, but it is currently believed to be an autoimmune disease. That is, the hemolytic streptococcus that invades the body of a sick dog can cause the body to produce corresponding antibodies. When certain predisposing factors exist that cause streptococcus to invade the body again, the invading streptococcus, as an antigenic substance, combines with the anti-streptococcal antibodies present in the body to form an antigen-

Mastiff Epidemic Report Released, Breeders Need to Pay Attention to Dog Health
When a legally designated infectious disease under national regulations occurs, the epidemic situation should be promptly reported to the higher-level competent business department, including the time and place of onset, the number of affected and dead animals, clinical symptoms, necropsy changes, preliminary diagnosis, etc. At the same time, appropriate prevention, control and eradication measures should be taken, and when necessary, neighboring areas or units should be notified so as to jointly carry out prevention and control. Before a diagnosis is made, dogs suspected of carrying infectious diseases should be isolated and placed under the care of specially assigned personnel; the places where dead dogs stayed as well as contaminated environments, equipment, etc. should be thoroughly disinfected; the carcasses of dead dogs should be kept intact pending examination; sick dogs must not be arbitrarily emergency-slaughtered without the consent of veterinary quarantine.
