Testosterone as a factor modifying the toxicity of ekatin for the pharaoh quail ( Coturnix coturnix pharaoh). I. Mature birds

1. Testosterone reduces the haemolytic action of Ekatin on the morphotic blood elements by accelerating maturation of erythroblastic cells. 2. Testosterone, by accelerating the metabolism of the pesticide causes a defective defence processes of the organism by decreasing the number of macrophages. 3. Intoxication of androgenised birds with Ekatin leads to a breakdown of the systemic adaptive mechanisms by rapid and early switching on the adrenal cortex in response to the stress caused by poisoning.

Changes in the blood and the bone marrow picture of the pharaoh quail ( Coturnix coturnix pharaoh) chicks as a manifestation of adaptation to postembryonal life

1. 1. The aim was determination of the rate of adaptation of the respiratory and defence functions of the blood and bone marrow of quail chicks. 2. 2. In the early post-hatching period, enhanced haemoglobin synthesis is the mechanism adapting the bird to the rich oxygen conditions beyond the egg. 3. 3. In 2-week-old chicks, the increased respiratory function of the blood is associated with a parallel rise of the erythrocyte count and haemoglobin content. 4. 4. The defence mechanisms of the chick in the first days after hatching are mainly connected with a high content of heterophilic granulocytes and in older chicks with a rising lymphocyte count.

Haematological changes in male and female pharaoh quails ( coturnix coturnix pharaoh) after ekatin intoxication

1. 1. The purpose of this study was to determine changes in the blood of pharaoh quails after Ekatin intoxication, to define the duration of disturbances caused by intoxication and to examine possible sex differences in the birds' reaction to intoxication. 2. 2. It was found that Ekatin reduced the number of erythrocytes, haemoglobin level and haematocrit value, increased erythroblast and reticulocyte numbers and increased the osmotic resistance of blood cells. 3. 3. It was shown that this pesticide caused neutrophilic leucocytosis with lymphopaenia and eosinopaenia. 4. 4. In males changes in the blood appeared far earlier than in females and they underwent compensation earlier, that is, 3 weeks after intoxication the majority of the haemotological parameters reached values similar to the control.

Outbreaks of Fowl Cholera in Quail

Acute fowl cholera causing high mortality was diagnosed in three flocks of quail, one involving pharaoh quail (Coturnix coturnix) and two involving bobwhite quail (Colinus virginianus). The causative organism, Pasteurella multocida, was identified as type 3.
