Sheep Hematology from Birth to Maturity I. Erythrocyte Population, Size and Hemoglobin Concentration

Normal Variations in the Haemoglobin Concentration in Mink Blood

“…No estimates of the haemoglobin concentration in mink kits younger than 6 weeks are available for comparison. However, the results agree well with studies in other animals (Andersen & Gee, 1958;Miller et al, 1961;Sunderman et al, 1953;Thomas & Axford, 1968; Thomas et al, 1954;Ullrey et al, 1965;Windle et al, 1940). The decline in the haemoglobin levels during the first weeks of life may be a physiological response associated with a great increase in the plasma volume.…”

“…The variation was especially great the first day of life, probably due in part to differences in age. Ullrey et al (1965) and Windle et al (1940) reported in their work with sheep and cats a great decline in the haemoglobin values during the first days of life. Accordingly, the mean haemoglobin values obtained the first day of life in the present study may be lon?er than the values of newborn kits.…”

Effect of straw on lamb welfare, production performance and meat quality during the finishing phase of fattening

“…In both treatments, the WBC, RBC, haemoglobin and haematocrit were lower in lambs with straw bedding and within normal reference ranges for weaning lambs of the same age (Lepherd, Canfield, Hunt, & Bosward, 2009;Ullrey, Miller, Long, & Vincent, 1965). Lower WBC in lambs without straw suggests some degree of immunosuppression, probably caused by chronic stress (i.e.…”

Blood oxygen flux estimation with a combined photoacoustic and high-frequency ultrasound microscopy system: a phantom study

“…Since HbR and HbO 2 have the same optical absorption coefficient at isosbestic wavelength (570 nm), the PA signal acquired at 570 nm is proportional to C Hb regardless of the sO 2 level. In previous study, 26 C Hb of the arterial sheep blood was measured to be 127 g∕L. We set this value as the C Hb of blood when quantifying oxygen flux.…”
