ABSTRACT

The aim of this work was to evaluate the environmental factors on ascites syndrome incidence. During September and December, an experiment with 24,000 Indian River x Peterson broilers was performed. Four broiler houses with a capacity for 6,000 birds each were divided in five commercial pens; Groups of 1200 one day old broilers were randomly assigned to the five repetitions. The following parameters were daily evaluated: minimum and maximum environmental temperature, variation range between minimum and maximum temperatures, mean temperature, relative environmental humidity, ammonia levels and mortality due to ascites syndrome. No significant differences (P›0.05) were observed in mortality due to ascites syndrome between temperature ranges and relative environmental humidities. However, significant ascites syndrome mortality differences (P‹0.05) occurred in temperatures under 12.5°C, temperature range variation between maximum and minimum above 11°C, mean temperature under 23°C and in ammonia levels above 14 ppm. Oxygen broiler demand may increase when it is raised in low temperatures, and when no stability between minimum and maximum temperatures is maintained. Oxygen demand increases in the presence of ammonia which diminishes the oxygen captation ability bringing up hypoxia which causes the ascites syndrome.
