		abstract={Hormonal factors will be very instrumental in follicle development is the hormone Follicle
Stimulating Hormone (FSH). If the lack of FSH hormone in the estrous cycle will cause the
symptoms of lambing in livestock less visible, so one of the physiological status of reproductive
disorders caused by hormonal disorders is the case of delayed ovulation. Delayed ovulation is a
condition where ovulation occurs not on time. The purpose of this study was to determine the
concentration of FSH in crossbreed cows that experience delayed ovulation. The samples used were
2 (two) Simmental crossbreed cows diagnosed with delayed ovulation owned by farmers in East
OKU district. Estrus intensity was observed during estrus until the end of estrus by looking at
follicular development with ultrasound (ultrasonography). FSH concentration was analyzed by
ELISA during estrus. The results showed FSH levels in Simmental crossbreed cows starting from
the 2nd day before estrus to the 6 day after the first estrus (day 0) consecutively: 2.75 mIU/ml; 2.75
mIU/ml; 2.65 mIU/ml; 2.29 mIU/ml; 1.88 mIU/ml; 2.45 mIU/ml; 2.6 ng/ml; 2.7 mIU/ml and 2.9
mIU/ml. Based on the results of the study, it can be concluded that simmental breeding cows that
experience delayed ovulation that causes estrus duration for 3 days show sequential FSH levels in
cows which are 2.65 mIU/ml, 2.29 mIU/ml, and 1.88 mIU/ml, and FSH concentration in cows that
experience delayed ovulation is smaller than normal cows.}
