Abstract: The K concentrations of red cells and the frequencies for HK gene were investigated in 5 cattle breeds, 2 goat breeds and in sheep; and the properties of the HK [high K+ concentration] red cell membrane were compared with those of the LK [low K+ concentration] red cells. The concentrations of K+ in red cells were determined by flame photometry. In several red cell samples of cattle and goats, 50% hemolytic score, osmotic fragility and recovery rates of frozen red cells were determined on HK and LK-type red cells. The gene frequencies for HK were as follows; Japanese Black cattle: 0.138 , Japanese Brown cattle: 0.190, Japanese Polled cattle: 0.239, Jersey cattle: 0.263, Shiba goats: 0.500, Saanen goats: 1,000. The HK gene was absent in Holstein cattle. The average gene frequency in 4 breeds of sheep was 0.356. Differences of HK gene frequency were found among the 5 cattle breeds and the 2 goat breeds. HK-type red cells had a lower 50% hemolytic score and a lower recovery rate of frozen red cells than LK-type red cells in both cattle and goats . There is apparently a difference in membrane properties between the HK and LK red cells. There was no relationship between osmotic fragility and K+ concentrating types, with respect to the association between K+ types and the Ma antigen, it was shown that the goat Ma antigen was a partial sheep Ma antigen consisted of 2 subtypes, that HK-type goat red cells were not wholly Ma-positive and that HK-type cattle red cells were Ma-negative.
