Abstract:
In the present study, a total of eighteen different farms with the history of sudden death syndrome (SDS) were investigated. Analysis of data revealed that the susceptibility age of sudden death syndrome was found to be as early as first week and age between 4 to 5 weeks highly susceptible. The average SDS mortality percentage in 18 broiler farms ranged from 0.61 to 2.49 per cent. Clinical signs, gross and histopathological changes have been recorded from field cases. SDS was induced by administration of lactic acid through crop intubation. Clinical signs observed included loss of balance, abruptly falling on to the ground, violent wing-flapping, strong muscular contractions and extended neck and legs. Majority of affected broilers were found dead lying on their backs. Serum sodium levels in the SDS birds were significantly decreased in treatment group birds. Potassium, Calcium, Magnesium, Phosphorus, LDH and CPK levels were significantly increased in treatment group when compared to control.
