TLDR
Fertility rates for all goats increased with time from the non-breeding to the breeding season and was more pronounced for Saanen goats than for Alpine goats, in which fertility increased only in the 45 day period preceding the beginning of the full breeding season.About:

Pharmaceutical Control of Reproduction in Sheep and Goats
TL;DR: Small ruminant species such as sheep and goats are short-day breeders, which is a crucial factor affecting the offer of lambs and kids throughout the year, and an appropriate management of reproduction allows ewes and does to breed in the spring to increase the supply of product to the marketplace on a year-round basis.

Effect of stress due to laparoscopy on plasma cortisol levels, the preovulatory surge of LH, and ovulation in the ewe
TL;DR: The ovulation which is induced in seasonally anovular ewes by the introduction of rams was used as a model to examine the effects of the stress of repeated laparoscopy on the preovulatory surge of LH and ovulation.

Diurnal variation in the response of anoestrous ewes to the ram effect
TL;DR: The re-introduction of rams after a period of separation was used to stimulate LH secretion and induce ovulation in seasonally anovulatory ewes maintained under natural photoperiod and there was a distinct diurnal variation in the secretion of prolactin.

TL;DR: It is concluded that prostaglandin is luteolytic when administered into does anytime beyond four days after the end of estrus.
