Mr Bhalavi said the carcass was lying there for last 4 to 5 days and was in a highly decomposed state as a result the postmortem could not be performed.
A skin sample has been sent to the forensic lab for DNA identification as per the guidelines of the National Tiger Conservation Authority (NTCA), said the official.
Similarly, camera trappings of the area are being scanned to identify the tigress.
Asked about the cause of the death, Mr Bhalavi said the tigress must have died due to organ failure or starvation.
On, January 14, a tigress was found dead due to respiratory failure in Pauni unified range of Pench reserve, he said.
Similarly, on February 14, a tiger was found dead due to territorial fight, informed Mr Bhalavi.
