“…Reid, Ward, and Salisbury (1948) reported an increase in erythrocyte GSH with age in cattle. Kunkel, Stutts, and Shrode (1954) found no difference in GSH values between calves and adult cattle, while Gurtler, Stephan, and Kolb (1965), Podgorski andMajewski (1969), andMabon (1969) have reported higher values in calves than in adults. In sheep, Kidwell et al (1958) reported no difference between GSH levels of lambs and ewes.…”

Reduced glutathione (GSH) levels of erythrocytes were determined in five sheep breeds. The Merino breed had a higher incidence of low GSH animals than the other breeds tested. High GSH type animals of the Border Leicester breed had a significantly lower mean GSH level than did higher GSH animals of the other breeds.GSH levels were found to be associated with electrolyte.levels, haemoglobin type, fleece weight, and body weight in Merino sheep.

“…Williams, Berry, and Beerstecher (1949) have suggested that the values of certain biochemical parameters are characteristic of the genotype and thus of use in breeding experiments. The levels of blood glutathione in young beef cattle (Kunkel, Stutts, and Shrode 1954) and plasma lipids in cows both in lactation and the dry period (Brungardt, Bray, and Hoekstra 1963;Kossila 1963) showed values characteristic of individual animals. The results of the investigations presented here [see Section III(d)] confirm that there are distinct animal differences in plasma cholesterol, phospholipid, and total lipid concentrations both within and between breeds which are maintained over a wide range of concentrations imposed by different physiological and environmental conditions.…”

“…In view of this and the effects of heat stress cited above, several workers have compared blood constituents of these two types of cattle (Kunkel et al 1953;Kunkel, Stutts, and Shrode 1954;Erwin 1960;Evans 1963). There appear to be no comparative studies of the blood lipids in tropical and temperate breeds of cattle under natural environmental conditions such as those found in subtropical and tropical Australia.…”

SummaryPlasma lipids have been studied in 77 British (Hereford and Shorthorn), 23 Brahman, 63 Brahman X British, 35 Africander, and 182 Africander X British grazing cattle. Cholesterol, phospholipid, and total lipid levels were significantly (P < 0·001) higher in Zebu breeds than in British breeds. The proportion of cholesterol present in the free state was relatively constant and given by the regression equation:where F = amount of cholesterol present in the free state and T is the total amount of cholesterol.Cholesterol and phospholipid levels were significantly higher (P < 0'01) in females than in males. Age was not a primary factor affecting the plasma lipid levels of adult cattle. Highly repeatable differences between animals within breeds were found in cholesterol and phospholipid levels. Estimates of heritability for cholesterol levels from dam-calf regressions were 34± 11 % and 100± 15% at calf ages of 10 and 22 months respectively.In heifers the triglyceride levels in Africander X British and British breeds were significantly higher (P < O· 01) than in the Africander, Brahman, and Brahman X British breeds. Plasma protein. bound iodine was consistently positively associated with cholesterol levels.Within breeds, animals with high plasma cholesterol carried significantly fewer mature cattle ticks (Boophilus microplus).The phospholipid-cholesterol balance for a given cholesterol level was different in males and females.

“…Recent reports indicate that glutathione (GSH) is primarily genetically controlled and may be associated with growth rate (Kunkel et al, 1954;Stutts et al, 1956;Stutts and Kunkel, 1958;Charkey et al, 1965;Best, 1966). Thus, the possibility of using GSH levels as an aid in selection is indicated.…”
