“…Other authors have not always obtained positive results. Arthaud et al (1959) looked for an association between growth rate and concentrations of Hb and glucose in the blood, but found none. Schultze (1955) failed to obtain any significant association between growth rate and glucose or Hb concentrations in 29 Holstein calves.…”

Blood samples, taken from each of 231 calves on three occasions at 9,10 and 11 weeks of age, were analysed for packed cell volume, blood glucose and Hb; and serum albumin, urea nitrogen, total protein, Ca, inorganic phosphate, Mg, K, Na and Cu. Differences in the blood composition for individual calves were demonstrated for all blood constituents (P < 0-01) with variations among calves proportionally largest for albumin and smallest for sodium. Concentrations of glucose, Hb and K were inherited (heritability estimates > 0-4).There were significant correlations (P < 0-001) between the calves' growth rates from 1 to 12 weeks and the concentrations of each of the blood constituents, glucose Hb, K, Na, albumin and inorganic phosphate; in the cases of Na and albumin, comparison of the blood analysis at 9-11 weeks with body weights at 6 and 9 months showed that these correlations persisted, and that by 9 months differences in concentrations of Na and albumin among individuals were associated with an average difference of as much as 55 kg in body weight.The evidence that concentrations of certain blood constituents are both inherited and related to growth rate suggests that not only might calves be screened early in life for indications of rapid growth rate, but also that animals might be bred to have the blood characteristics indicative of this quality.

“…Shultze (1955) found correlations of -0-32 to -0-38 between rate of gain, erythrocyte count, haematocrit value and haemoglobin content of the blood. Arthaud et al (1959) concluded the red cell fraction of the blood to be useless for predicting performance since the correlation coefficients ranged from only -0-14 to +0-14. The haemoglobin content of the blood showed close agreement with the red cell fraction.…”

“…The relationship of certain blood constituents, such as protein-bound iodine, haemoglobin and erythrocytes, to the performance of dairy and beef cattle, as well as pigs, has received the attention of research workers during the past years (Kunkel, Colby & Lyman, 1953;Kunkel, Green, Riggs, Smith & Schrode, 1957;Arthaud, Shultze, Koch & Arthaud, 1959, with beef cattle; Shultze, 1955, andLennon &Mixner, 1959, with dairy cattle;and Gawienowski, Mayer & Lasley, 1955, with pigs).…”

The serum protein-bound iodine concentration in the blood of beef steers varied between animals and was not correlated with the daily gain during the fattening period. The data, however, are insufficient to arrive at a definite conclusion.The average erythrocyte counts of the blood were 7·86 (range: 5·89–8·75), 8·59 (range: 6·55–10·15), and 8·54 (range: 5·23–9·62) million per mm.3 for steers of 14, 26 and 38 months of age. The difference between the counts of the yearlings and that of the other age groups was statistically significant. The red cell fraction increased with live weight over the range 700–1230 lb. Although a significant (P < 0·01) correlation was found between the number of erythrocytes in the blood and the daily gain of the steers, the erythrocyte count cannot be employed to predict the possible gaining ability of single beef animals.The haemoglobin content of the blood was found to be 14·02 (range: 9·8–17·4) in the case of the yearlings, 14·68 (range: 11·8–18·5)and 14·61 (range: 7·95–16·85) g./100 ml. blood in the case of the 2-year-olds and 3-year-olds respectively. These differences between age groups were not significant.A correlation of 0·31 was found between the haemoglobin content and live weight of steers within the weight range of 600–1230 lb. The data suggest that for every 100% increase in weight, the haemoglobin in the blood increased by 17%. No correlation was found between the haemoglobin content and the rate of gain of the steers.
