OSORIO, JOSÉ HENRY; URQUIJO, LINA MARÍA  and  SALAMANCA, DIANA MARCELA. FACTORS WHICH MODIFY THYROID HORMONES LEVELS IN DOMESTIC BIRDS. Luna Azul [online]. 2011, n.33, pp.126-136. ISSN 1909-2474.

Objective: to analyze the factors which modify the thyroid hormone levels in domestic birds. Materials and methods: information from the last 50 years included in the BBCS-LILACS, Fuente Académica, IB-PsycINFO, IB-SSCI, IB-SciELO, Scopus and Scirus, data bases as well as historical articles, texts and references cited in work published to date were analyzed. Results: important information related to the objectives proposed in the present review was found and analyzed. The information was later divided into two sections as follows: synthesis, liberation and metabolism of thyroid hormones and factors which modify the thyroid hormones levels. Conclusion: thyroid hormones production can be influenced by factors such as temperature, incubation, diet, fasting, photoperiods and stress.
