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...

On the Frequency of Spontaneous Tumors in the Domestic Fowl

1. Analysis of records from the Storrs Contest, the Harper Adams Trials, and a farm flock indicate an increase of tumors in the second half of the pullet year (May through October) over the first half (November through April). 2. Some evidence seems to indicate that heavy antecedent egg production is associated with a rise in tumor rate. 3. The normal annual tumor rate for fowls between the age...

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...
