Extract

The haemoglobin values for the blood of clinically normal cows and ewes over England and Wales are very similar, with a mean value around 11·5 g. per 100 ml. Although the extreme range is wide, about 8–17 g., the distribution of values is such that the common normal range may be taken as 9·5–13·5 g. per 100 ml. There is no striking difference in age groups.

Metabolic disorders such as ‘milk fever’ and ‘grass tetany’ in cows and ‘pregnancy toxaemia’ in ewes have no specific effect on haemoglobin level. Chronic hypoglycaemic ketosis of the dairy cow leads to progressive anaemia in which levels down to 6 g. per 100 ml. were found. Border or Northumbrian ‘pining’ of sheep is accompanied by an even more pronounced progressive anaemia, values as low as 3·2 g. per 100 ml. being encountered.

It is a pleasure to acknowledge the technical assistance of Mr F. J. Salt and the direction and interest of Dr H. H. Green in the main programme from which the protocols were drawn.
