At the same time, it is recommended that chicken farmers pay attention to the prevention and control of the following 6 common diseases to avoid these diseases.
1. Chicken Colibacillosis
Chicken colibacillosis is caused by Escherichia coli. It does not specifically refer to a certain disease, but a comprehensive name for a series of diseases. The main symptoms are: inflammation of the organs such as pericarditis and perihepatitis.
Preventive measures: reduce the stocking density of chickens, disinfect regularly, and ensure the cleanliness of drinking water and feed. The treatment of chicken colibacillosis generally uses targeted drugs for treatment. Adding such drugs when the chicks start to eat can also play a certain preventive effect.
2. Chicken infectious bronchitis
Avian infectious bronchitis is caused by infectious bronchitis virus, which is an acute and infectious respiratory disease. The main symptoms are: cough, rales, sneezing and so on.
Preventive measures: 3 to 5 days old chicks can be immunized. You can use the vaccine to drip the nose or use a doubled dose of drinking water. At the age of January to 2 months, you need to use the vaccine again for double immunization. At present, infectious bronchitis in chickens does not have very effective drugs to treat, and antibiotics can be used in the early stage of the disease to prevent the development of infection.
3. Big head and fat face syndrome
The swelling around the eyes, head and face, even the lower collar, and wattles of sick corns are typical of "big head and fat face", and they show certain neurological symptoms such as head shaking and torticollis. The disease is a multi-factorial infectious disease caused by avian pneumonia virus and secondary pathogenic Escherichia coli and other bacterial infections.
Prevention and treatment methods: improve the breeding environment; prevent secondary bacterial infections, choose sulfamonomethoxine 0.03%, ciprofloxacin or ampicillin for treatment, and may appropriately cooperate with antiviral drugs; injection of attenuated vaccines or inactivated vaccines for immunization.
4. Abdominal swelling syndrome
Chickens at the age of 4-5 weeks are prone to this disease: abdominal enlargement, purple head and face, difficulty breathing, and gradual exhaustion and death. Necropsy of the dead chicken showed that the abdomen was filled with light yellow fluid, pericardial effusion, right heart dilation, pulmonary congestion, edema, liver and gastrointestinal atrophy, and congestion. The disease is caused by chronic hypoxia, cold, high ammonia concentration and lack of selenium, vitamin C, phosphorus and genetic factors in the house.
Prevention and control methods: prevent the feeding of sulfonamides and furan drugs that are more toxic to the kidneys and liver; aminoglycosides, quinolones and other antibiotics should not be used too much; this disease often secondary to colibacillosis or chronic respiratory disease, Can choose ampicillin or amoxicillin (10g/100kg water), ciprofloxacin (5-10g/100kg water) antibacterial drugs to prevent secondary infection; add selenium auxin per 100 kg of feed 500 grams, while adding an appropriate amount of vitamin E.
5. Fatty liver syndrome
The disease is a nutritional disorder caused by fat metabolism disorders in chickens. Suffering from chicken combs and pallor anemia of meat-beards, discharge of gray and thin feces, stretched head and neck or bent back, fell to the ground and cramped, and died of weight loss after the birth.
Prevention and control methods: control the energy level in the diet and increase the protein content by 1-2%; add 100 grams of choline chloride, 50 grams of methionine, 5 grams of multivitamins, 1212 mg of vitamin B, and 0.05-0.1 selenium per 100 kg of feed Milligrams; sick chickens are fed separately, each fed with 0.1-0.2 grams of choline chloride and 1 milligram of vitamin E. At the same time, take 30 grams of Bupleurum, 20 grams each of Scutellaria baicalensis, Salvia miltiorrhiza, Alisma, 10 grams of Schisandra chinensis, grind them, and feed them at a dose of 1-2 grams per bird.
6. Bad habits syndrome
Intensified chicken farms in spring, due to insufficient nutrition in the diet or improper proportions of various nutrients, coupled with poor environment and management disorders, a large number of chickens pecking anus, feathers, toes, eggs, and mutual pecking Chicken body and other bad habits.
Prevention and control measures: beak trimming for the first time at 5-9 days old, and beak trimming for the second time at 10-12 weeks old; prepare full-price rations, feed rationally, and manage scientifically; maintain proper stocking density; Add 1-2% gypsum powder and 1-2% salt to the diet; isolate the sick chicken in time, and apply tincture of iodine, purple syrup, camphor oil, etc. to the wound to prevent ulceration.
