If the tissue is not fixed soon after death the microscopic morphology will be terrible, no matter whether the animal is refrigerated or frozen. The person suggesting refrigeration/freezing is (obviously) not familiar with histological technique. As someone else on the list suggested, better planning is needed for the harvesting of tissues for microscopy.

Dear Group Members,
I have a strange query, One person suggested, if the animals for necropsy are 
more and one can not handle the load of necropsy  on the same day.
Then simply after sacrificing the animals refrigerate the dead animals to 
reduce the autolysis process and then proceed with the actual necropsy 
procedures.
  is it possible to to the necropsy procedures on the freezed animals samples 
for further histopathology evaluation?
expert comments are suggested.
Regards
krishna
