TL;DR: The recent improvements of embryo production and freezing technologies could be used for constitution of flocks without risks of disease transmission and will allow wider propagation of valuable genes in small ruminants populations in the future.

TL;DR: 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.

TL;DR: The results show that the low fertility rate observed in some herds after synchronization of estrus and AI may be related to the high proportion of goats with a late occurrence ofEstrus, and this phenomenon increases in animals that are treated repeatedly.

TL;DR: A cooperative action between the partners of the dairy goat industry has operated since 1992 with the aim of reducing the variability of fertility rates, which includes improvement of the control of reproduction by hormonal treatments, AI conditions, embryonic mortality and pseudopregnancy.

TL;DR: Estrus synchronization with a norgestomet implant or half-implant did not reduce the variability in the onset of estrus and LH peak and no significant difference was observed, for the same parameters, in animals receiving implants.
