Selenium influences growth via thyroid hormone status in broiler chickens.
As there is a possibility that Se influences the growth of animals via thyroid hormone metabolism, the following three experiments were undertaken in order to determine the effects of dietary Se on growth, skeletal muscle protein turnover and thyroid hormone status in broiler chickens. Broiler chickens were raised on a Se-deficient diet until 12 d of age and then used for the experiments. In Ex...
متن کاملThe effect of thyroid hormone status on plasma glucose-insulin interrelationship in broiler chickens.
The aim of the present experiments was to study the plasma glucose-insulin relationship in eu-, hypo- or hyperthyroid broiler chickens. None of the thyroid states modified the fasting plasma glucose and insulin levels. Hypothyroid chickens exhibited a normal glucose tolerance and a normal glucose-induced insulin release after oral glucose (2 g/kg body weight) administration compared to euthyroi...
متن کاملLow selenium status in the elderly influences thyroid hormones.
1. Iodothyronine 5'-deiodinase, which is mainly responsible for peripheral triiodothyronine (T3) production, has recently been demonstrated to be a selenium-containing enzyme. In the elderly, reduced peripheral conversion of thyroxine (T4) to T3 and overt hypothyroidism are frequently observed. 2. We measured serum selenium and erythrocyte glutathione peroxidase (as indices of selenium status),...
متن کاملEffects of hyper- or hypothyroid status on growth, adiposity and levels of growth hormone, somatomedin C and thyroid metabolism in broiler chickens.
Relatively few methods involving dietary manipulation of thyroid status have been used to study the effect of that status on growth and body composition as well as on changes in hormone levels and metabolism. The present work examines the influence of either a hyperthyroid status (induced by feeding triiodothyronine: T3 or thyroxine: T4) or a hypothyroid status (induced by feeding methimazole: ...
متن کاملRelationship between venous blood gas parameters, thyroid hormone levels and ascites syndrome in broiler chickens exposed to cold temperature
The objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. One hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. Toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...
