EFFECTS OF SHORT-TERM THYROXINE ADMINISTRATION DURING THE LAYING PERIOD ON EGG-PRODUCTION AND MOLTING BY TURKEYS

BRITISH POULTRY SCIENCE, 34(2), 405–416.

By: R. Lien n & T. Siopes n

MeSH headings : Animals; Eating / drug effects; Female; Light; Oviposition / drug effects; Thyroxine / administration & dosage; Thyroxine / blood; Thyroxine / pharmacology; Triiodothyronine / blood; Turkeys / physiology
TL;DR: Results indicate that although short term elevation of plasma T4 causes cessation of egg production and moulting these effects are transient and not indicative of photorefractoriness. (via Semantic Scholar)

THE RELATIONSHIP OF PLASMA THYROID-HORMONE AND PROLACTIN CONCENTRATIONS TO EGG-LAYING, INCUBATION BEHAVIOR, AND MOLTING BY FEMALE TURKEYS EXPOSED TO A ONE-YEAR NATURAL DAYLENGTH CYCLE

GENERAL AND COMPARATIVE ENDOCRINOLOGY, 90(2), 205–213.

By: R. Lien n & T. Siopes n

MeSH headings : Animals; Feathers / physiology; Female; Light; Maternal Behavior; Oviposition / physiology; Prolactin / blood; Seasons; Thyroid Hormones / blood; Thyroxine / blood; Triiodothyronine / blood; Turkeys / physiology
TL;DR: To determine relationships to egg laying, incubation behavior and molting, plasma thyroxine, triiodothyronine, and prolactin levels of 20 female domestic turkeys were determined throughout a one-year cycle of natural daylengths. (via Semantic Scholar)

INFLUENCE OF THYROIDECTOMY ON REPRODUCTIVE RESPONSES OF MALE DOMESTIC TURKEYS (MELEAGRIS-GALLOPAVO)

BRITISH POULTRY SCIENCE, 32(2), 405–415.

By: R. Lien n & T. Siopes n

MeSH headings : Animals; Fertility; Male; Organ Size; Reproduction; Semen / physiology; Sex Characteristics; Sexual Maturation; Sperm Count / veterinary; Testis / anatomy & histology; Testis / physiology; Thyroid Gland / physiology; Thyroidectomy / veterinary; Thyroxine / blood; Triiodothyronine / blood; Turkeys / physiology; Turkeys / surgery
TL;DR: The requirement for the thyroid glands in the reproductive processes of male turkeys changes either with age or after an extended period of reproductive activity. (via Semantic Scholar)

TURKEY PLASMA THYROID-HORMONE AND PROLACTIN CONCENTRATIONS THROUGHOUT AN EGG-LAYING CYCLE AND IN RELATION TO PHOTOREFRACTORINESS

POULTRY SCIENCE, 68(10), 1409–1417.

By: R. Lien n & T. Siopes n

MeSH headings : Animals; Female; Oviposition / physiology; Photic Stimulation; Prolactin / blood; Thyroid Hormones / blood; Thyroxine / blood; Triiodothyronine / blood; Turkeys / blood; Turkeys / physiology
TL;DR: Elevated plasma T4 may be involved in development of photorefractoriness in turkey hens, increases in plasma T3 may have been involved in gonadal regression and molting, and elevated plasma prolactin was associated with persistence of photosensitivity. (via Semantic Scholar)
