Abstract

The objective of this study was to evaluate the incidence of egg bound syndrome in the year round culled commercial layers of Hyderabad region. The growth and automation of commercial egg production has developed faster and progressed further than any other type of livestock. Culling is an essential management practice to maintain the health of the flock and high egg production. Egg bound syndrome is one of the reason for culling. A total of 122 culled commercial layers were examined for prevalence of egg bound syndrome. All the birds were subjected to ante-mortem and postmortem examination at NRC on Meat slaughterhouse. During ante-mortem examination about 6% of layers were suspected for egg bound syndrome. The suspected bird’s signs were noticed like distended abdomen with hardening on palpation (2%), fluffed feathers (1%), weakness (1%), difficult breathing (1%) and sitting fluffed on the bottom of the floor (1%). During post mortem examination, inflamed oviducts distended with egg and yolk mass were observed. Out of 122 layer birds examined, 8% of layers were observed with egg bound syndrome of which 2% have extended to egg peritonitis. From the above findings it was concluded that 8% of egg bound syndrome incidence in culled commercial layers of Hyderabad region.
