Broiler Ascites Syndrome is a non-communicable disease characterized by obvious ascites, right ventricular dilatation, pulmonary congestion, edema, and liver lesions. It has become one of the world's most dangerous diseases in the broiler industry. In April 2003, the author participated in the treatment of a relatively serious broiler ascites disease in a chicken farm in Suizhong County. The results are good. The report is as follows. 1 Incidence The farmer Ma uses two home soil houses as a brooding room to breed Ai Wei chicken. The room area is 35 square meters. There is no ventilation except for one window, and the indoor stove is used for heating. A total of 3084 chicks were bred. The chicks were from a 1-day old meat Ai Wei chicken in a hatchery in Lanzhou, and the feed was a brand-name pelleted chicken feed. At 25 days of age, some of the broilers showed lassitude, abnormal movements, and reluctance to walk around, especially abdominal enlargement, palpation of abdominal fluctuating sensations. At 30 days of age, the condition became more severe and some of the chicks died. 2 clinical symptoms The diseased chicken suffers from loss of appetite, weight loss, unruly feathers, unwillingness to exercise, difficulty breathing, and hair loss. The auscultation of the abdomen had blown water, rapid breathing, and rapid heartbeat. The diseased chicken's abdomen was swollen and was in the form of a water bag. There was a sense of volatility in the contact pressure, and the abdomen became thin and shiny. In severe cases, the skin became red and bloody. Some sick chickens are difficult to stand up. They are penguin-like on the abdomen and are slow-moving duck-like. Peritoneal puncture flows out of a clear, pale yellowish liquid. A total of 30 cadaveric dead chickens were found. The cardiopulmonary disease was found to have different degrees of dilation. The liver injury was hardened, the spleen was markedly atrophic, and there was a lot of pale yellow liquid in the abdomen. Each organ was accompanied by different degrees of blood stasis. 3 Diagnosis and Cause Analysis According to the above conditions, diagnosed as broiler ascites. Based on the comprehensive analysis, the author believes that the causes of ascites occurred in the broiler chickens in Ma: (1) The house has extremely poor ventilation, lack of oxygen, and high levels of harmful gases such as ammonia, carbon monoxide, carbon dioxide, and hydrogen sulfide. (2) The energy content in the diet is too high and vitamins are lacking. (3) The feeding space is too small, causing the chickens to raise the density seriously, especially as the chicken grows up, so that the area occupied by individual units becomes narrower and smaller. (4) Long-term use of a single drug. In order to prevent the chickens from getting sick, Ma added sulfa drugs to drinking water from the beginning, causing broiler liver and kidney damage. 4 Prevention 4.1 Immediately improve the feeding environment of the broiler, transfer a portion of the broiler to another sterilized brooder room to rationalize the overall density of the flock. 4.2 Immediately stop feeding the previously used drugs to the chicken oral hydrochlorothiazide, 5ml / only, 2 times / day, and even served 3 days. 4.3 Feeding of broiler chickens is restricted to reduce the energy intake and growth of broilers. Adjust diet mix, increase vitamin content, reduce high-energy feeds, and change feeds into pellet feeds and powder feeds. 4.4 Strengthen the scientific management of brooding. Install an exhaust fan in the brooding room to regularly adjust the indoor air. Remove the chicken manure once every 2 to 3 days to reduce the impact of harmful gases such as ammonia on the flock. 5 Summary and recommendations Ascites disease is a common disease in broiler chickens, especially in the case of brooders, which should attract the attention of the farmers. The disease is a complex multi-factor production problem. It is not an independent disease. It is necessary to take preventive measures as the main effect. Comprehensive prevention and treatment can receive the best results. The author proposes: (1) The majority of farmers must do scientific breeding and scientific management. The brooding room should be well-ventilated, fresh air and ground chicken waste. Feed your chickens with clean drinking water and feed on a balanced diet. Diligently observe that the flock has abnormal behavior and immediately identify the cause and deal with it. Adjust the breeding density of the flock to prevent it from becoming too dense. (2) Restricted feeding of chickens, especially when they are limited to 7 to 14 days and 35 to 42 days of age, can effectively control ascites without adverse effects on growth. (3) Strengthen the disinfection work inside and outside the house to reduce the occurrence of respiratory diseases in the flock to prevent the initiation of syndromes. (4) Reasonably control the illumination time. (5) Reduce the stress response of the flock to improve the body resistance of the chicks. (6) Reasonable use of drugs that have side effects on the liver and kidneys. In particular, when the disease is prevented, the same type of drug should not be used for a long period of time. It should be stopped after a period of time, and another type of drug should be used.

After one week of treatment, the chickens died and his condition improved. After 3 weeks of flocking, 85% of the chickens recovered.
