Seasonal Changes of FSH, LH, Total and Free Testosterone Hormones in Saanen Bucks

Abstract

In the study, seasonal changes in follicle-stimulating hormone (FSH), lutein hormone (LH), total testosterone (TTH), and Free Testosterone Hormone (FTH) of Saanen goats were investigated. In order to determine the hormone levels between February 2019 and December 2019, blood samples were taken from bucks (n=6) twice a week during the entire trial. FSH level started to decrease relatively after August and the lowest value was determined as 173.01 mlU/ml in January. The difference between the months in the mean FSH level was found to be significant (p
