ABSTRACT
Sadeghi S, Moradi Kor
N., Trace elements concentration of ovarian follicular fluid in relation to
follicle size in dairy cows, Onl J Vet Res.,
17(9):490-495, 2013. Level of trace elements in ovarian follicular fluid and
follicular size in Holstein cattle is reported. Ovaries were recovered from 40
female adult cows (Holstein Friesian) 5–7 years of age with clinically normal
reproductive tracts after slaughtering. Visible follicles on the surface of the
ovaries were classified based on their diameter as small (3-5 mm), medium
(6-9 mm) and large (10-20 mm). Follicular fluid samples were analyzed for iron,
iodine, copper, manganese, zinc, cobalt, molybdenum and selenium. Results
showed that concentration of trace elements were different between follicles
sized categories. Follicular fluid concentrations of iodine and manganese
between follicles sized categories were significant (p ≤ 0.05). The
findings suggest that the levels of trace elements in the follicular fluid were
related to follicular size in dairy cows.
