Eg, ewe or ram (5)
I believe the answer is:
sheep
I believe this clue is a double definition.
'eg ewe' is the first definition.
(I know that ewe is a type of sheep)
'ram' is the second definition.
(I know that ram can be written as Sheep)
(Other definitions for sheep that I've seen before include "Source of lamb" , "Dolly or Shaun" , "Source of mutton" , "Woolly animals" , "Woolly animal" .)
