VADODARA: Kamatibaug Zoo, the favourite garden for morning walkers, witnessed a major scare when stray dogs left six blackbucks in an enclosure dead on Friday morning.Two other blackbucks were badly injured as stray dogs sunk their teeth deep into the bodies. Blackbucks are highly protected species under schedule I of the Wildlife Protection Act.According to zoo officials, the stray dogs may have entered the enclosure through some openings or scaled its fencing. A security guard at the zoo heard some noises in the enclosure and rushed there. The guard alerted other security personnel at the zoo and the officials were also informed.Three security guards rushed into the enclosure and scared the dogs away. However, the damage was already done. Six blackbucks had collapsed inside the enclosure and they were found dead on examination by the zoo officials. The condition of two others is said to be serious and they are under treatment.Zoo curator Dr Pratyush Patankar said that the blackbucks were sensitive and timid animals. “They would have been scared due to the dogs and may have run amok. The deaths may have taken place due to shock and not because of the wounds by dog bites,” said Patankar.Officials said that the dead blackbucks were disposed of by burning their bodies as per the norms of the Central Zoo Authority of India . An autopsy was performed and a detailed report will be prepared by the officials and sent to the Vadodara Municipal Corporation (VMC) that manages the zoo as well as other officials concerned. Veterinarians of the animal husbandry department had also remained present during the autopsy of the blackbucks.A source in the zoo said that the blackbucks had bite marks only on their backs. “These could not have been fatal. Only three or four of them were bitten by the dogs,” the source said.The enclosure had 11 blackbucks and only three exist inside it now.
