Blood and Bone Marrow Cells of the Domestic Fowl

1. A simple, direct method of counting leucocytes of the fowl is described. 2. Twenty-nine complete, morphological studies of the blood of eleven domestic fowls are recorded. 3. The characteristics of the cells found in the blood and bone marrow are described in detail and their relative numbers reported. 4. The supravital technique, using neutral red and Janus green, enables one to separate an...

Renal function in domestic fowl.

SKADHAUGE, ERIK, AND BODIL SCHMIDT-NIELSEN. Renal function in domestic fowl. Am. J. Physiol. 2 12 (4) : 793-798. 1967.Roosters were exposed to water and salt loading and to dehydration. The ureteral urine was collected through polyethylene funnels. The glomerular filtration rate (GFR) was found to increase an average of 23 yO from dehydration to hydration, when at the same time the urine flow i...

Hereditary hypothyroidism in the domestic fowl.

OPULATIONS of fully pedigreed chickens often contain individuals which ’deviate considerably in one or more respects from the average for the flock. When pedigrees reveal close genetic relationship among those similarly affected, further studies are warranted. Such was the case for the trait now recognized as hypothyroidism. Affected 5 %-month old White Leghorn pullets, which were somewhat smal...

Renal acid excretion in the domestic fowl.

1. In order to assess the role of uricotelism in net renal acid excretion, blood and ureteral urine samples were collected from five hens fed a commercial poultry feed (Diet A) and five hens fed a protein-rich, Na-poor feed (Diet B). All samples were analysed for pH, PCO2, ammonium, phosphate, uric acid and urates (UA + U) and inulin. 2. On Diet A, average pH in venous blood was 7.42, while uri...
