An Example of Incomplete Glandular Hermaphroditism in the Domestic Fowl

An Hereditary Complex in the Domestic Fowl.

Brachydactyly, syndactyly, and leg-feathering or ptilopody‘ are among the many characteristics of the domestic fowl that have been studied from the standpoint of genetics. The last in particular, owing to its widespread occurrence, has aroused especial interest. Its heredity has been investigated by HURST (1905), DAVENPORT (1909), and more recently by PUNNETT and BAILEY ( 1918). The genetic beh...

Decerebration of the Domestic Fowl.

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...

Studies on an Uncomplicated Coryza of the Domestic Fowl

Minute coccobacilliform bodies have regularly been found in the nasal exudate of fowl infected both by injection and by contact with the coryza of slow onset. These bodies are commonly less than 0.5micro in diameter and are predominantly extracellular. They have consistently failed to grow in artificial media. They are held back by Berkefeld V filters which are impermeable to Hemophilus gallina...

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...
