A haematological investigation was carried out on the population of the Island of Westray situated in the Orkney Isles, North Scotland. The response rate was 98.8 per cent and 291 males and 289 females over the age of 15 years had a blood examination. Anaemia in the male population (defined as 12.5 g. haemoglobin per 100 ml. of blood or less) was 4.1 per cent and in the female population (defined as 12 g. haemoglobin per 100 ml. of blood or less) was 14.5 per cent. In the male population, the prevalence was found to increase with age, from 2 to 3 per cent in the younger age groups to 8 per cent at 55 years and over. In the female population, the highest prevalence was in the 35 to 44 years age group (25%) and in women over 75 years (23%). There was a statistically significant reduction of mean corpuscular haemoglobin concentration (M.C.H.C.) with age in all the male age groups studied. There was a similar significant association between age and M.C.H.C. in the female population under 75 years of age. Reduction in the M.C.H.C. with a normal haemoglobin level was found in 13.4 per cent of the males and in 18.7 per cent of the female population.

The present paper extends the knowledge of selected blood indicators in six species of feathered game such as helmeted guineafowl (Numida meleagris), common pheasant (Phasianus colchicus), Japanese quail (Coturnix coturnix japonica), chukar (Alectoris chucar), grey partridge (Perdix perdix) and wild turkey (Meleagris gallopavo), reared in the Czech Republic and Europe. The red blood cell (RBC) values in individual species of feathered game ranged as follows: the mean RBC counts varied in a range of 2.10 - 2.58 T/l; haematocrit values were in a range of 0.33 - 0.39 1/1; haemoglobin concentration varied in a range of 101.20 - 129.13 g/l; mean corpuscular haemoglobin concentration (MCHC) ranged from 28.63 to 35.44%; mean corpuscular haemoglobin (MCH) varied in a range of 46.15 - 62.07 pg and the mean corpuscular volume (MCV) was 147.66 - 178.20 fl. Except for the total concentration of haemoglobin and the mean corpuscular haemoglobin concentration, no significant differences were found between the mean values of RBC values in individual species of feathered game. However, some differences between species were found in white blood cell (WBC) values, ranging as follows: the total WBC count ranged from 13.55 to 26.90 G/l, basophil granulocytes from 0.011 to 0.110 G/l, eosinophil granulocytes from 0.011 to 0.593 G/l, neutrophil granulocytes from 1.868 to 6.661 G/l, lymphocytes from 10.937 to 20.922 G/l and monocytes from 0.034 to 0.199 G/l. Most values showed significant (P ⪬ 0.05) to highly significant (P ⪬ 0.01) interspecies differences. The main goal of the study was to investigate selected haematological indicators in six major species of feathered game.

The aim of this study was to find whether the magnitude of changes in blood before and after horse endurance competitions was the same at the beginning and the end of the season and if the studied indices could be useful in assessing the impact of such changes on the length of the endurance racing season. The study was conducted on 36 clinically healthy horses. Blood samples were taken during 60-km endurance competitions in 2014, three times in total. The study revealed an increase of lymphocytes (× 1.89-2.05; P < 0.001), red blood cell count (× 1.11-1.12; P < 0.001), and a decrease in the mean corpuscular haemoglobin concentration (× 1.20-1.27; P < 0.001), red cell distribution width (× 1.11; P < 0.01), platelet concentrations (× 1.33-1.40; P < 0.05), when compared at the beginning and in the end of the horse endurance racing season. During the entire season, haematocrit values significantly increased after the race but were at their lowest in the mid-season period. The results proved a significant increase in the white blood cell and granulocyte counts following the finish of a 60-km endurance race, when comparing the values at the beginning and in the end of the horse endurance racing season, and a significant reduction in lymphocytes when comparing the values at the beginning (35.7%) and at the end (29.7%) of the season. The endurance competition season highly influences haematology indices in horses' blood, however, to determine the season's impact on the results of the race, additional studies must be conducted.

The effect of Goezia leporini Martins & Yoshitoshi, 2003 (Nematoda: Anisakidae) infection on the haematological characteristics of cultivated Leporinus macrocephalus (Osteichthyes:Anostomidae) was studied. Paleness of gills, kidneys, liver and heart, black spots on the kidney and accumulation of fluid in the visceral cavity, stomach and intestines were observed. Gall bladder content had pale and translucent aspect. Strong and slight positive correlations between number of nematodes and fish weight were estimated within the 0-100g and 100-200g fish weight group, respectively. Blood smears from infected fish showed variation in erythrocyte size (anisocytosis) and shape (poikilocytosis), and also dividing erythrocytes. No significant alteration (P>0.05) was shown as to erythrocyte, leukocyte count, haemoglobin concentration and thrombocyte and monocyte percentage. Parasite infection provoked significant reduction (P<0.05) in hematocrit, mean corpuscular volume, mean corpuscular haemoglobin concentration and lymphocyte percentage. On the other hand, significant increase (P<0.05) in neutrophil and eosinophil percentage in circulating blood of infected fish was observed. This is the first report regarding haematology of nematode infected freshwater cultivated fish in Brazil.

The aim of this study was to investigate the influence of storage time at +4 °C on haematological indicators in rainbow trout Oncorhynchus mykiss (Walbaum, 1792). For this purpose, 60 Italian trout were evaluated and red blood cells, white blood cells, thrombocyte count, haematocrit, haemoglobin concentration, mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were determined. After blood collection (T<sub>0</sub>), all samples were immediately analysed using an automatic method to assess the haematological parameters and then divided into two different aliquots and stored at +4 °C. The first aliquot was refrigerated for 168 h (T<sub>1</sub>), the second one for 336 h (T<sub>2</sub>). Statistical analysis (one-way repeated-measures ANOVA) showed a significant effect of storage time (P &lt; 0.05) on red blood cells, thrombocyte count, haematocrit, haemoglobin concentration, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. The obtained data expand our knowledge of haematological evaluation techniques and could contribute to the development of an appropriate method for haematological analysis that is suitable for the evaluation of the health status of wild and farmed fish.
