“…The blood levels of ascorbic acid obtained in turkeys are within the range of values obtained for chickens (Holmes et al, 1939(Holmes et al, , 1940Scrimshaw et al, 1949;Perek and Kendler, 1963). Therefore, it is unlikely that a species difference exists in the ascorbic acid level in the blood.…”

“…In some species such as the chicken and the pigeon this synthesis occurs primarily in the kidney (Roy and Guha, 1958). Holmes et al (1939Holmes et al ( , 1940 observed no relationship between blood level of ascorbic acid and egg production in chickens. Feeding ascorbic acid to chickens at either a high level (2,600 mg./kg.…”

Summary Deficiency of vitamin C in the diet of chickens depressed the activity of the thyroid gland, as detected by radioiodine uptake. The activity of the thyroid of chickens depends not only on its content of vitamin C., but also on the dose of the vitamin C supplement fed to the chickens. A dose of 100 mg. per kilogram diet restored the thyroid function of chickens while a dose of 50 mg did not. Data are shown in tables and figures of thyroid activity, serum uptake and percentage of tyrosine and thyronines, by the use of 125I injected intraperitoneally in chickens. Zusammenfassung Die Wirkung von Vitamin C auf die Schilddrüsenaktivität bei Küken Vitamin‐C‐Mangel im Kükenfutter vermindert die Schilddrüsenaktivität (Untersuchung mit Hilfe der Radiojodaufnahme). Die Schilddrüsenaktivität der Küken hängt von der Dosis der Vitamin‐C‐Supplementierung des Futters ab. Eine Vitamin‐C‐Dosis von 100 mg/kg Futter stellte die Schilddrüsenfunktion wieder her, während das bei einer Dosis von 50 mg nicht der Fall war. Anhand von tabellarischen und grafischen Darstellungen wird die Schilddrüsenaktivität sowie die Aufnahme von Tyrosin und von Thyroninen in das Blut bei intraperitonealer Applikation von 125J dargestellt. Résumé Action de la vitamine C sur l'activité de la glande thyroïde chez des poussins Le manque de vitamine C dans la nourriture diminue l'activité de la glande thyroïde chez les poussins (recherche faite á l'aide de iode radioactif). L'activité de la glande thyroïde dépend chez les poussins de la dose en vitamine C additionnée dans l'alimentation. Une dose de 100 mg de vitamine C par kilo d'aliment remet en fonction la glande thyroïde, ce qui n'est pas le cas avec 50 mg. On a représenté graphiquement et avec des tableaux l'activité de la glande thyroïde ainsi que la présence de tyrosine et de thyronine dans le sang au moyen d'application intrapéritonéale de 125J. Resumen La acción de vitamina C sobre la actividad tiroidea de los pollitos La deficiencia vitamínica C en el pienso para pollitos disminuye la actividad tiroidea (experiencia con ayuda de yodo radiactivo). La actividad tiroidea de los pollitos depende de la dosis del suplemento vitamínico C en el pienso. La dosis de 100 mg. vitamina C por kilo de alimento restablecía la función de la glándula tiroidea, mientras que una dosis de 50 mg. no lo hacía. A la vista de representaciones tabulares y gráficas, se expone la actividad tiroidea, y la toma de tirosina y de tironina por la sangre con la aplicación intraperitoneal de 125J.
