Title

THE INFLUENCE OF LOW ENVIRONMENTAL TEMPERATURE ON THE INCIDENCE OF ASCITES SYNDROME AND THE METABOLIC PARAMETERS IN BROILER CHICKENS AT HIGH ALTITUDE

Pages

  94-98

Abstract

ASCITES SYNDROME is a metabolic disorder in BROILER CHICKENS. Chronic hypoxia is the major causes of ascites that could be due to a lower providing of oxygen e.g. HIGH ALTITUDE and/or due to a higher oxygen requirement e.g exposure to lower environmental temperature.In this study 576 BROILER CHICKENS were housed at low altitude and feed a basal diet until 21 days of age. At this age, the chicks were transported. To a HIGH ALTITUDE farm 2000 m above sea level, and randomly divided over two rooms. The birds in room one were maintained at a normal ambient temperature (22oc) while the birds of second room were subjected to a lower ambient temperature (13 oc). Exposure of BROILER CHICKENS to 2000 m of HIGH ALTITUDE increased ascites mortality. The incidence of ascites was markedly higher (62.7%) compared to birds were subjected to a normal ambient temperature. The higher ascites mortality was coincided with lower body weight of birds, higher haematocrit values, heterophil/ lymphocyte ratios and thyroid hormones activity. This result indicate that the ascites incidence will be severely raised when BROILER CHICKENS is exposed to two stresses, COLD TEMPERATURE and HIGH ALTITUDE, at the same time.
