  • Oxytocin synthesis and release by the bovine corpus luteum

    Creator:
    Abdelgadir, Salaheldin Eltigani
    Abstract:
    Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...

  • Embryonic mortality in pubertal gilts

    Creator:
    Archibong, Anthony Effanga
    Abstract:
    An experiment was conducted to compare the reproductive performance and serum concentrations of progesterone and estrogen of mated first (n=18) and third (n=18) estrous gilts slaughtered in equal numbers on days 3, 15 and 30 postmating. Fertilization rate did not differ between mated first and third estrous gilts. Embryonic survival...

  • In Vivo and In Vitro effects of a cyclopropenoid fatty acid on progesterone synthesis by the ovine corpus luteum

    Creator:
    Tumbelaka, Ligaya
    Abstract:
    Two experiments were conducted to examine the effect of a cyclopropenoid fatty acid on luteal cell function. In Exp. 1, 12 mature ewes were mated to a fertile ram, assigned to two groups (n = 6/group) and laparotomized on day 18 of gestation. Ewes with corpora lutea (CL) in both...
