Phoenix and Fowl: Birds of a Feather

A aviary, the vast collection of bird paintings in Chinese art, reflects longstanding global fascination with our feathered friends. Balanced on two legs, like humans, and able to fly and swim, birds have been viewed as an engineering miracle in the East and West and have been studied by artists and scientists alike. Traditional Chinese painting goes back 6,000 years to the Neolithic period and...

Thermal behavior of fowl feather keratin.

Differential scanning calorimetry (DSC) was applied to elucidate the thermal behavior of fowl feather keratins (barbs, rachis, and calamus) with different morphological features. The DSC curves exhibited a clear and relatively large endothermic peak at about 110-160 degrees C in the wet condition. A considerable decrease in transition temperature with urea and its helical structure content esti...

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...

Nutrition and reproduction in the domestic fowl.

In the domestic fowl (Gallus domesticus) the fertilized egg in the infundibulum of the oviduct consists of an enormous mass of yolk about 40 mm in diameter on which rests the blastodisc about 3 mm in length. The whole is enclosed by a vitelline membrane, but as the egg passes down the oviduct (a process requiring about 24 h) albumen is deposited around it, shell membranes are laid down enclosin...
