The effects of Leptospira serotype pomona in sheep of different haemoglobin types

Abstract

Extract

In the majority of adult sheep there are one or both of two genetically determined haemoglobin types designated Hb-A or Hb-B. The three phenotypes are A, AB or B. These haemoglobin types can be identified by differences in electrophoretic mobility (Harris and Warren, 1955; Evans et al., 1956). A third haemoglobin type, designated Hb-C, is associated with the Hb-A gene and is produced underconditions resulting in anaemia (Blunt and Evans, 1963). There is some evidence of a relationship between haemoglobin types and variations in certain physiological characteristics or productive traits (Agar et al, 1972).
