mammals only have nucleated RBC's while still in the bone marrow. once they mature, the nucleus is "picked out", leaving a donut-shaped disk. if a mammal is actively producing many RBC's (such as in a hemolytic anemia) there will be some nucleated RBC's present in the peripheral blood.
of the vertebrates, reptiles, birds, fishes, and amphibians have nucleated RBC's.

All mammals except for horses can develope nucleated RBCs if they have various hemolytic anemias. RBCs with such are diagnostic proof of chronic hemolytic anemia (CHA).The RBCs are non-regenerative (cannot replicate themselves).

first of all it is spelt mammal not mamel
i could b wrong
in mammals the nuclei is lost and the RBCs become biconcave disk like in structure .
this helps them to accomodate more oxygen (RBCs carry gases from the lungs to other parts of thje body) their structure helps them to do their work efficiently.

No mammals have nucleated red blood cells (references 1,2,3).
From Wikibooks (reference 3):
"Red blood cell (erythrocyte): contains hemoglobin, functions in oxygen transport. In mammals, red blood cells lose nuclei on maturation, and take on biconcave, dimpled, shape."
