The following red cell characters were studied in a herd of 217 calves repre-senting Brahman cross, Africander cross, Grade Brahman, and British (Hereford X Shorthorn) breeding, and in their dams: packed cell volume, haemoglobin level, red cell count, fragility, potassium and sodium concentrations, catalase activity, and haemoglobin type. There were distinct breed differences. In some characters, e.g. packed cell volume and potassium concentration, Africander cross were inter-mediate between Brahman cross and British, whereas in others, e.g. fragility and catalase activity, they were indistinguishable from British. Within breeds, the characters showed highly repeatable differences between animals and high herita-bilities.

Sheep were used to compare the anemia effects of fresh marrow-stem kale (Brassica oleracea var. acephala D.C.) with low-temperature dehydrated marrow-stem kale (MSK). There was a drop in hemoglobin (P < 0.01), packed-cell volume (P < 0.05), and red blood cell count (P < 0.05) after the 4th, 5th, and 6th wk, respectively, of feeding fresh MSK. Similar drops in hemoglobin (P < 0.05), packed-cell volume (P < 0.05), and red cell count (P < 0.05) occurred after the 4th wk of feeding dried MSK. Formation of Heinz-Ehrlich bodies peaked at the corresponding lowest values of hemoglobin and packed-cell volume for both fresh and dried MSK. These criteria returned almost to normal in the 2nd and 3rd wk after stopping the feeding of kale and using ground hay as the entire ration instead. It was concluded that high levels of either fresh or dried MSK could not be fed to sheep even for a relatively short period of time.

Anaemia is only a symptom and not, in itself, a diagnosis. Its importance lies in the fact that it signals underlying disease which is often correctable. By definiton anaemia is a reduction in red cell mass and this is reflected in reduced haemoglobin, packed cell volume, or red cell count in the peripheral blood. To understand the mechanisms of its development normal blood formation must be briefly reviewed.

Twenty-four steers, comprising British (Herefords and Hereford x Shorthorn crosses), Zebu (Africander), and Zebu cross (British x Brahman or Africander) breeds, were maintained either on pasture or yarded, and fed on diets of a low and a high nutritional value. Blood volumes were determined on five occasions at intervals of 3 months by the 51Cr labelling technique, plasma and red cell volumes being then derived from the venous haematocrit. The blood plasma, and red cell volumes are all very significantly, correlated with, and represent respectively 4.97, 3.27, and 1.70% of, the fasting body weight. To avoid the confounding effect of body weight, the parameters are expressed as "contents", i.e, in terms of volume per kilogram fasting body weight. In the grazing group breed differences were generally absent. This may in part be due to the fact that the Zebu crossbreds belonged mostly to the F2 and partly to the F3 generation. In the yarded group, where F1 crossbreds were compared with British steers, breed differences were more frequent. British steers tended to have higher plasma contents, but lower red cell contents and haematocrits. Nutrition had no effect on plasma contents, but good nutrition was generally associated with higher haematocrits, as well as with elevated blood and red cell contents. Seasonal differences were in evidence, and all parameters generally reached minimal values in winter or spring. The significance of these findings in relation to adaptation to a tropical environment is discussed. The haematocrit does not necessarily reflect changes in the red cell volume. There is also some indication that the water and plasma contents may be related. The possible usefulness of the red cell volume for predicting the body composition is discussed.

No significant changes were found in packed cell volume, haemoglobin concentration and red cell glutathione levels in patients before and after anaesthesia with halothane or enflurane. These results, though unable to explain the mechanism, support the earlier suggestion that glutathione plays little, if any, role in protecting liver against toxic effects of these anaesthetic agents or their metabolites.

Physiological Differences

1. Evidence is given of an association between the two loci governing inheritance of haemoglobin type and erythrocyte potassium concentration in Welsh Mountain sheep.2. In the 1777 animals examined, there was an excess of high potassium types amongst carriers of the haemoglobin B gene.3. At both high and low levels of potassium, sheep possessing haemoglobin A only had significantly more potassium in their blood than animals possessing haemoglobin B only. AB heterozygotes were intermediate in. value.

AbstractIn a sample of 105 concordant sex MZ and DZ twin pairs, the following characteristics were measured: red cell count, haemoglobin concentration, package cell volume, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, reticulocytes, platelets, white cell count and the six types of leucocytes, lymphocytes, monocytes, band and segmented neutrophils, eosinophils and basophils. The statistical model employed in the univariate twin analysis allows for three sources of variation: genetic (h2), shared environmental (c2) and specific environmental influences (e2). A genetic component was significant for red cell count, haemoglobin and mean cell haemoglobin (0.64, 0.60 and 0.46 respectively), with heritable variation suggested for package cell volume, mean cell volume, mean cell haemoglobin, lymphocytes and monocytes. Shared environmental variation was only present for neutrophils.

Haemodilution in nine neonates resulted in significant mean (SEM) decrease of packed cell volume (0.67 (0.01) to 0.55 (0.01)) and increases in cardiac output (250 (16) to 308 (25) ml/min/kg) and blood flow velocities of the internal carotid artery and the coeliac artery (+20%). However, red cell flows in the aorta, carotid and coeliac arteries did not change during haemodilution, thereby indicating that haemodilution did not improve oxygen transport.

Anaemia denotes a reduction in the circulating haemoglobin level or red-cell count below that which is normal for the individual’s age and sex. Anaemia is common and may be a primary problem or a feature of a wide variety of other conditions. This chapter covers the approach to diagnosis, diagnostic tests, therapies, prognosis, and dealing with uncertainty in the initial diagnosis.
