Abstract
The importance of serum concentrations of cortisol and thyroid hormones in metabolic process have been emphasized since old days. Aim of this study is to investigate the analysis of serum concentrations of cortisol and thyroid hormones and the correlation between them during lactation, pregnancy and dry periods in Saanen goats. A total of twenty female adult Saanen goats at age of 3 years with a body condition score of 3.5 (in the beginning of experiment) and average weight of 30.2±2.20 kg were selected. The animals were reared under the same management conditions and definite feeding program (according to their maintenance and physiologic demands). The whole duration of the study was divided into three periods including dry (non-pregnant) period, four-month single pregnancy (at the end of the fourth month) and lactating period. Serum concentrations of cortisol were increased and those of thyroid hormones were decreased significantly (p<0.05) during different periods (from dry period to pregnancy and pregnancy period to lactation). There was a significant negative correlation between serum concentrations of cortisol and thyroxin (T4) (p<0.05, r=-0.44) as well as between serum concentrations of cortisol and triiodothyronine (T3) (p<0.01, r=-0.88) in pregnancy period. There was no significant correlation between serum concentrations of cortisol and thyroid hormones during lactation period. These changes are not necessarily indicative of disease but may reflect the physiological status of animal. Serum concentrations of cortisol and thyroid hormones can be used as a marker to evaluate the metabolic status in various physiological conditions in dairy goats.
