This study aimed to investigate the effect of hyperketonemia on estrogen, progesterone and ovarian follicle size during postpartum as well as on pregnancy rate at first insemination. Regarding this, 90 Holstein cows were selected from one of the industrial dairy farms in Isfahan province, Iran. Estrus synchronization was routinely applied to all cows using the Ovsynch method. The blood sample of the cows was taken two times. The first blood sample was taken in 7-14 days after calving; to measure betahydroxybutyrate (BHBA), and the second sample was taken at the first insemination to measure the 17-ß oestradiol and progesterone hormones. …

In this study, the effect of buck presence on serum progesterone, estrogen and FSH levels during the premating in 20 female Akkeçi goats was investigated. The goats were assigned to two groups as follows: control group (n = 10) and treatment group (n = 10). At the beginning of study, first blood samples (day 0) were taken from each goat kept isolated away from bucks at mating season. At day 13, female goats in treatment group were placed in a pen next to, that of bucks in order to provide buck effect. Second blood samples were taken from each does …
