Species and Sex Differences in the Percentage of Plasma Trapped in Packed Cell Volume Determinations on Avian Blood

Effect of Centrifugal Force on Packed Cell Volume and Trapped Plasma in Avian Blood

“…Direct comparison is of limited value, however, because of differences in centrifugal conditions and markers employed. The data reported here and by Hunsaker (1969) for avian species may, therefore, also be underestimated. The data reported here and by Hunsaker (1969) for avian species may, therefore, also be underestimated.…”

“…Beilin et al (1966) confirmed the data of Maizels and Remington (1959) that the amount of intercellular plasma remaining in the centrifuged RCM of human blood will be underestimated when iodinated human serum albumin is used as the marker. Further data on species and sex differences in TP will be given in another report (Hunsaker, 1969). The significant species difference in TP was probably not related to differences in reproductive state in view of the similarity in TP values for laying and non-laying hens.…”

Blood: Physical Characteristics, Formed Elements, Hemoglobin, and Coagulation

“…Hunsaker (1969) centrifuged blood of chickens, geese, and turkeys at 3215 X g for 30 min in macrotubes and determined hematocrits and the amount of plasma trapped, with the erythyrocytes and leukocytes making up the packed cell volume. The percentage of trapped plasma averaged from 2.35 in goose blood to 3.21 for chicken blood, with turkey blood intermediate.…”

Effect of Some Antioxiadnts and Methyl- Donors on the Productive and Reproductive Performance of Turkey Hens

“…Immediately after collection, blood sample was transferred into two tubes, a heparinized tube and non-heparinized one. Heparinized whole blood samples were used for the determination of hemoglobin concentration according to Pilaski (1972) and haematocrit value, as described by Hunsaker (1969). The separated sera from non-heparinized blood samples were used for the colorimetric estimation of levels of glucose (Trinder, 1969), total protein (Henry et al 1974), albumin (Doumas et al 1977), cholesterol according to Watson (1960) and total lipids according to Zollner and Kirsch (1962), using commercial kits.…”
