The Rate of Thyroxine Secretion by the Thyroid Glands of White Leghorn Cockerels *
The physiology of the thyroid gland has become of increasing interest to us because of the observations made by Graham3 and the confirmation by others that the feeding of dried thyroid gland or the injection of thyroxine would dramatically increase the milk yield and fat secretion of many dairy cows. The effect of thyroxine upon the rate of growth and body type and conformation has been suggest...
متن کاملXylazine, diazepam and midazolam premedicated ketamine anaesthesia in white Leghorn cockerels for typhlectomy.
Thee different combinations of ketamine hydrochloride were used to induce general anaesthesia for surgical operations (typhlectomy) in 30 adult, single-comb White Leghorn cockerels. They were randomly divided into three groups, each comprising 10 birds. Birds in Group I received xylazine-ketamine combinations at the dose rate of 2 mg xylazine and 10 mg ketamine per kg i.v., whereas birds of Gro...
متن کاملAcute heat stress induces oxidative stress and decreases adaptation in young white leghorn cockerels by downregulation of avian uncoupling protein.
Reactive oxygen species-induced damage of cells and molecules is one of the mechanisms responsible for the decline in an animal's performance due to heat stress. Mitochondria are the main producers of cellular superoxide, a process that is sensitive to proton motive force, and this superoxide production can be decreased by mild uncoupling. We studied the effects of heat stress on the production...

15 صفحه اولChromosomal localization of three endogenous retrovirus loci associated with virus production in White Leghorn chickens.
Proposed mechanisms for the generation of endogenous retrovirus loci have been examined by determining the chromosomal distribution of these loci by means of in situ hybridization. Unlike the clustering on chromosome 1 of five endogenous retrovirus loci associated with the gs- chf- phenotype A. Tereba and S. M. Astrin, submitted for publication), three loci associated with endogenous retrovirus...
