Electrolyte concentrations in the erythrocytes of the goat and ox

Genetic polymorphism of blood potassium in goat belonging to the different breeds and subbreed in Mongolia

“…The goats represent the second species after sheep, on the extent of potassium polymorphism investigation. In comparison with other species in which, in most breeds, the phenotype LK is predominant [4,5,7,8,20], in the Mongolian native, GoviGurban Saihan breeds and Altai ulaan sub breed goats, the phenotype LK is widespread, so the results are not similar to the some other studies in goat breeds [17,18]. But, this characteristic is also common on the phylogenetic scale of species.…”

“…The polymorphism of erythrocyte potassium was for first time detected in sheep by Evans and King [4]. The existences of polymorphism for potassium in red blood cells or whole blood were confirmed in goat [5,12,14,15,16,23,24] . Furthermore, several studies have reported, as well as in sheep, some associations between the biochemical polymorphism of potassium, other blood electrolytes and various production traits [10,12,18,20].…”

“…Many studies have noted distributional discontinuity of potassium in the blood of animals, which has suggested that this chemical element presents polymorphism having genetic determinism [2,3,5,7,810,11,13,17,21,22]. The polymorphism of erythrocyte potassium was for first time detected in sheep by Evans and King [4].…”

Differences in the Concentration of Potassium and the Type of Haemoglobin Between Strains and Sexes of Merino Sheep

“…The frequency of the gene responsible for animals with HK erythrocytes varies from breed to breed and is higher in mountain and northern European breeds than in lowland and African breeds (Evans and Mounib 1957;Evans, Harris, and Warren 1958b). Two red blood cell potassium types have also been found in goats (Evans and Phillipson 1957), possums (Barker 1958), and in the ox (Evans, unpublished data 1960). The mode of inheritance has been described (Evans and King 1955) and studies of the two types of sheep in relation to water metabolism (Evans 1957b), a number of husbandry criteria (King et al 1958), other blood factors (Mounib and Evans 1959), and the concentration of potassium in the tissues (Mounib and Evans 1960) have been reported.…”

Studies on the Sodium-Potassium Balance in Erythrocytes of Australian Merino Sheep LI. Observations on Three Merino Strains

“…As no haemoglobin analyses were made in our observations, the influence of haemoglobin type on the [K+] level could not be checked (Evans, Harris, and Warren 1958). Environmental influences may, of course, be producing variability, but the observed differences between means of breeds, strains, and sire groups indicate that at least some of the variation is of genetic origin, and it seems likely that polygenes are operating on the [K+] level as well as the major gene pair, as was suggested by Evans and Phillipson (1957) for cattle. The numbers of observations here are too small for reliable estimates of heritability, but it is hoped that some may be possible later.…”
