Prevention of sudden death in broilers

Sudden death from broilers is characterized by acute dissemination and early onset of well-nourished broilers. Clinical manifestations. Without incubation period, the sick chicken often screamed and fell to death and died within seconds. Control methods: (1) Reduce feed nutrient levels. The three-phase feed protein and energy content was 4% and 12.5 MJ, 20% and 12 MJ, and 19% and 11.5 MJ, respectively. At the same time, vegetable oil was used instead of animal fat, and the effect of changing the granular material to powder was better. . (2) Limit feeding. Feeding was restricted from the second week to the fifth weekend when feeding pellets. The specific approach is to use three feeds a day, and it is better to eat each feed for one hour. (3) Increase ventilation. In particular, one hour before and after feeding, negative pressure ventilation should be performed to improve the air environment inside the house. To reduce the burden on the heart and lungs of chickens under stress, thereby reducing the incidence of the disease. (4) Supplement with sodium bicarbonate. Add 0.2% sodium bicarbonate to chicken drinking water every week to prevent the disease. (5) Reduce stress. In order to reduce the incidence of the disease, the chicken house should be built in a quiet place to minimize the stress on the flock. (6) Drug therapy. If the disease has already occurred in chickens, vitamin C can be added to drinking water, and at the same time, aspirin enteric-coated tablets with a concentration of 2010-6 can play a good therapeutic effect.
