REPRODUCTIVE PERFORMANCE OF DOMESTIC FOWL MAINTAINED UNDER CONTINUOUS LIGHT

Reproductive Performance of Domestic Fowl Maintained under Continuous Light.

When domestic fowl were maintained under constant incandescent illumination from time of hatching, the rate of egg production was similar to that of control birds on a diurnal schedule. Hatchability offertile eggs produced by such hens was found to be unaffected by lighting treatment of the parents. Fertility was, however, markedly impaired in the males reared under continuous light. Artificial...

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...

The effect of administration of gonadotropin releasing hormone analogue at estrus or during luteal phase on reproductive performance of dairy cows maintained under sub-temperate climate

Overall, 531 dairy cows were inseminated with the aim to study their reproductive performance following administration of GnRH analogue on different days of estrous cycle with different doses. These cows were divided into six treatment and one control group. Depending upon different treatment groups, Buserelin acetate was injected at a dose of 10.5 µg or 21.0 µg on different days (0, 5 or 12) o...

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...
