Pecking and initial drinking responses in young domestic fowl.

Responses of domestic fowl to excess iodine: a review.

Typically, poultry diets contain 1-2 mg I/kg, but higher concentrations are sometimes used to enhance the I content of eggs. In addition to an increased deposition of I in the yolk, other often adverse responses occur, especially at exceptionally high concentrations. Excess I in grower diets can prevent sexual maturation in male and female fowl, and in layer diets will progressively reduce egg ...

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...

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...
