A case study of artificial feeding of an unweaned giant otter (Pteronura brasiliensis) cub

Marcia Munick Mendes Cabral, Carolina Ribas, Fernando Cesar Weber Rosas


There is no information available on the nutritional content of giant otter milk, nor about the amount of milk consumed by the cubs. The information presented here is intended to help ex situ institutions to raise and rehabilitate giant otter orphan cubs with an artificial milk formula and provide hand-rearing information for their management in captivity.
