Hormonal Profile of Ovarian Follicular Fluid and Blood Plasma during Different Stages of Estrous Cycle in Holstein Cattle
نویسندگان
چکیده مقاله:
The aim of this study was to evaluate the concentrations of reproductive hormones in blood plasma and in follicular fluids of different sized follicles during various stages of the estrous cycle in Holstein cattle. Jugular blood samples from 42 adult Holstein cattle were collected immediately after the slaughter. Antral fluids from small (4-5 mm), medium (6-9 mm) and large (10-20 mm) follicles were collected and the stages of estrous cycle were recorded. The gonadotropin and steroid concentrations in blood plasma and steroid levels in follicular fluid were measured. Estradiol-17-ßconcentrations in antral fluids of small follicles in early diestrous were significantly(P0.05). The plasma concentrations of FSH, LH and estradiol-17-ßin proestrous and estrous were higher than the other stages of the cycle (P

متن کاملOvarian follicular activity and hormonal profile during estrous cycle in cows: the development of 2 versus 3 waves
Most estrous cycles in cows consist of 2 or 3 waves of follicular activity. Waves of ovarian follicular development comprise the growth of dominant follicles some of which become ovulatory and the others are anovulatory. Ovarian follicular activity in cows during estrous cycle was studied with a special reference to follicular waves and the circulating concentrations of estradiol and progestero...
متن کاملFollicular development during four stages of the estrous cycle of beef cattle.
Estrogen and progestin concentrations in plasma and follicular fluid (FF) of follicles within the small (5 to 100/A), medium (101 to 400 gd) and large (>400 gtl) range, numbers of follicles and volume of FF per follicle within these ranges were determined in beef heifers. There were differences (P<.01) in mean concentrations (+SE) of steroids among and within follicles from the small, medium an...
متن کاملCopper and zinc concentrations in the uterine fluid and blood serum during the bovine estrous cycle
To investigate uterine and serum copper (Cu) and zinc (Zn) concentrations variation during the bovine estrus cycle , 232 blood and genital tract samples were collected from the abattoir in Urmia. The phase of the estrous cycle was determined by the examination of the ovaries and the uterine tonicity. Of the 46 samples selected for use in the study, 13 were pro-estrus, 10 estrus, 8 metestrus, an...
متن کاملOvarian follicular populations at two stages of an estrous cycle in heifers given high energy diets.
Sixteen crossbred heifers were assigned at random on d 3 of an estrous cycle to continue to receive the medium quality hay (control diet) or to be flushed with a grain ration (high-energy diet) until slaughtered on d 12 or 16. The ovarian follicles were counted and measured using routine histological techniques. Both the nonatretic and atretic (more than four pyknotic bodies) antral follicles (...
متن کاملChanges of acute-phase proteins during different phases of the estrous cycle in Ovsynch-synchronized Holstein cows
Background: Acute-phase proteins (APPs) may be increased due to different stresses during estrus phase in farm animals. Aims: Determining changes of APPs at different phases of non-synchronized estrous cycle group (NSEG), and Ovsynch-synchronized estrous cycle group (SEG) in Holstein cows. Methods: Twelve non-pregnant clinically and paraclinicaly healthy Holstein cows with a body condition scor...
