Effects of prostaglandin administration on ovarian follicular dynamics, conception, prolificacy, and fecundity in sheep.
Two experiments were conducted to determine the effects of prostaglandin administration on ovarian follicular dynamics, conception, prolificacy, and fecundity in sheep. During the breeding season,Expand

The use of prostaglandins in controlling estrous cycle of the ewe: a review.
This review considers the use of prostaglandin F(2α) and its synthetic analogues (PG) for controlling the estrous cycle of the ewe. Aspects such as phase of the estrus cycle, PG analogues, PG doses,Expand

Reproductive outcome with GnRH inclusion at 24 or 36h following a prostaglandin F2α-based protocol for timed AI in ewes.
The objective of this experiment was to study the reproductive performance obtained after a short-interval prostaglandin (PG) F2α-based protocol for timed artificial insemination (TAI) in sheepExpand

Conception rates in ewes after AI with ram semen preserved in milk-egg yolk extenders supplemented with glycerol.
This study aimed at comparing the effect of ram semen preserved at 5 °C on two milk-based extenders (UHT skim milk or INRA-96(®) , 5% egg yolk) supplemented with 2% glycerol, and the preservationExpand

Comparison of prostaglandin- and progesterone-based protocols for timed artificial insemination in sheep.
The objective was to compare the reproductive performance of a new PGF(2α)-based timed artificial insemination (TAI) protocol in sheep (Synchrovine®: two doses of PGF(2α), 7 d apart) to a traditionalExpand

Concentrations of steroid hormones, estrous, ovarian and reproductive responses in sheep estrous synchronized with different prostaglandin-based protocols.
To determine estrous, ovarian and reproductive responses after different prostaglandin (PG)-based protocols, ewes were assigned to groups PG10, PG12, PG14 or PG16 (twoPG injections administered 10,Expand

Alternatives to improve a prostaglandin-based protocol for timed artificial insemination in sheep.
The objective was to improve the reproductive performance of a prostaglandin (PG) F(2α)-based protocol for timed artificial insemination (TAI) in sheep (Synchrovine®: two doses of 160 μg ofExpand
