Efficacy of a prostaglandin analogue in reproduction in the cycling mare.
TLDR
The prostaglandin F analogue was without side-effects, and hence should be of value in manipulating the estrous cycle of the mare.About:

Concentration of prostaglandins F in uterine venous plasma of anesthetized mares during the estrous cycle and early pregnancy.
R.H. Douglas,O.J. Ginther +1 more
TL;DR: Prostaglandins F were quantitated by radioimmunoassay in uterine venous plasma of anesthetized mares on day 7 of estrus, days 2, 6, 10, 14 or 18 of diestrus and days 10, 11, 12, 13, 14 and 18 of pregnancy.

Prostaglandin F2α specific binding in equine corpora lutea
TL;DR: PGF 2α specific binding was demonstrated in corpora lutea collected at known stages of the estrous cycle and competition of several natural prostaglandins for equine luteal PGF 2 α specific binding sites indicates specificity for the 9α-hydroxyl moiety and the 5,6-cis doublebond.
Journal ArticleDOI
Control of the oestrous cycle of the mare
TL;DR: This review summarizes recent progress in knowledge of the physiological situations countered in the mare and of natural and artificial control of the physiology processes that lead to ovulation.
Journal ArticleDOI
Regression and resurgence of the CL following PGF2α treatment 3 days after ovulation in mares
TL;DR: PGF treatment 3 days after ovulation resulted in structural and functional regression of the CL and hastened the interval to the next ovulation, despite post-treatment resurgences in progesterone.

Effect of prostaglandin F2a on length of diestrus in mares
R.H. Douglas,O.J. Ginther +1 more
TL;DR: Five groups of pony mares were treated, subcutaneously, with 0 (controls), with 0, 1.25, 2.50, 5.00, or 10.00 mg of PGF 2a on day 6 of diestrus, finding that mean length of diesta was shorter than for the control group.

Control of the mare's oestrous cycle by prostaglandins
W. R. Allen,L. E. A. Rowson +1 more
TL;DR: There is now ample evidence that PGF2\g=a\is the uterine luteolytic hormone which terminates the life of the CL in many species and in the mare, unilateral hysterectomy prolongs the life-span of theCL in some animals but not in others, and the proportion in which luteal maintenance is affected.

Ovarian Activity During the Estrous Cycle of the Mare
Journal Article
Effect of human chorionic gonadotropin on duration of estrous cycle and fertility of normally cycling, nonlactating mares.
TL;DR: The effect of a single dose (3300IU) of human chorionic gonadotropin (HCG) given on Day 1 or 2 of estrus on the duration of estrous cycle and fertility of normally cycling nonlactating mares was studied.

TL;DR: This study supported previous findings that the majority of non-pregnant mares which are not showing regular oestrous cycles during the breeding season are in prolonged dioestrus rather than anoestrus.
