Autor: F E, Van Niekerk, C H, Van Niekerk, G, Reid, J, Coetzee

Publikováno v: Journal of the South African Veterinary Association. 61(4)

Comprehensive blood typing (17 factors) and electrophoretic protein markers (haemoglobins, transferrins and albumins) were determined on S.A. Mutton Merino sheep (n = 275). The frequencies of these genetic markers were compared between ram lambs with
