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...

Seminal Plasma Protein as a Biomarker for Fertility and Hatchability in the Domestic Fowl Gallus Domesticus

This study was aimed at investigating the use of seminal plasma protein concentration to predict fertility and hatchability in the domestic fowl. Forty cocks with acceptable sperm motility and morphology were used and the seminal plasma protein concentration determined by the Biuret method. The result revealed a negative significant correlation between the seminal plasma protein concentration w...

Inheritance of Body Weight in Domestic Fowl.

and genetical behavior of this form is not incompatible with the segmental interchange theory of circle formation in Oenothera. Summary.-It is impossible for the alethal complex of a primary halfmutant derived from Lamarckiana by a single segmental interchange to give the same chromosome configuration with both complexes of the parent species. Nevertheless, a further segmental interchange betwe...

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...
