Endocrine studies in young chickens of the obese strain.
TLDR
Differences between chicks of the Obese strain and those of the parent strain have been investigated and a difference in the plasma growth hormone concentration was found in the 4-week-old birds.About:

Journal ArticleDOI
Hormones and Growth in Poultry
TL;DR: The available evidence supports the concept that growth hormone and the thyroid hormones are the principal hormones responsible for the attainment of normal growth in the domestic fowl.

The Obese Strain of Chickens: An Animal Model with Spontaneous Autoimmune Thyroiditis
TL;DR: For example, the thyroid glands of obese strain (OS) chickens become severely infiltrated by mononuclear cells and the occurrence of numerous germinal centers is a characteristic histological hallmark of the disease as discussed by the authors.
Journal ArticleDOI
Adipose Tissue Metabolism and Its Control in Birds
TL;DR: The relative role of hormones in fat metabolism, some pecularities of insulin activity in birds, and the important functions of plasma lipoprotein and adiposelipoprotein lipase are discussed.
Journal ArticleDOI
Effects of hyper- or hypothyroid status on growth, adiposity and levels of growth hormone, somatomedin C and thyroid metabolism in broiler chickens.
TL;DR: Both of the statuses (hypothyroid and hyperthyroid) profoundly changed peripheral thyroid hormone metabolism and influenced GH/Sm-C relationships, but in the opposite way.
Journal ArticleDOI
Ascites in broilers. 2. Disturbances in the hormonal regulation of metabolic rate and fat metabolism.
TL;DR: Overall results suggest that the occurrence of HFS and ascites in SS birds could be initiated independently by different factors, which might be a limited thyroid hormone production and a lower capacity for oxygen consumption.

The Bursa of Fabricius and Antibody Production
TL;DR: Although reticular cells of lymph glands and lymphocytes may participate in globulin and antibody synthesis (Raffel, 1953), suspicion regarding the importance of the bursa in antibody production arose in the following accidental manner.
Journal ArticleDOI
Rapid Effects of Single Small Doses of L-Thyroxine and Triiodo-L-thyronine on Growth Hormone, as Studied in the Rat by Radioimmunoassay1
TL;DR: The mea-urement by RIA of changes in GH content of the rat pituitary may provide the most adequate parameter available at present for a biological effect in vivo of single doses of the thyroid hormones, a measurement clearly related to an important physiological role.
Journal ArticleDOI
Evidence in the Hypophysectomized Pigeon of a Synergism Among Prolactin, Growth Hormone, Thyroxine and Prednisone Upon Weight of the Body, Digestive Tract, Kidney and Fat Stores
TL;DR: Various levels of dosage of prolactin and/or growth hormone, alone and in combination with thyroxine and prednisone, were injected daily for 10 days into hypophysectomized pigeons, finding greater increases in the weight of body and of organs when the auxiliary solution was found.
Journal ArticleDOI
TRF and Thyroid Hormones on Prolactin Secretion By Rat Anterior Pituitary Cells in Vitro
TL;DR: The effect of pGlu-His-Pro-NH2 (TRF) on the secretion of prolactin (PRL) from rat anterior pituitary glands and cell cultures derived from normal and propylthiouracil (PTU)-fed rats is reported.
Journal ArticleDOI
Alterations of Radioimmunoassayable Growth Hormone and Prolactin during Hypothyroidism
TL;DR: Induction of hypothyroidism by treatment of rats with propylthiouracil (PTU) or radioactive iodine reduced pituitary and plasma growth hormone concentrations and administration of cortisol to chronically Hypothyroid animals failed to increase pituitsary growth hormone content.
