••
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.
319 citations
••
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.
127 citations
••
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.
115 citations
••
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.
97 citations
••
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.

TL;DR: The major strides and obstacles in human and other vertebrate oocyte and embryo cryopreservation will be reviewed here.
Abstract: Preservation of female genetics is currently done primarily by means of oocyte and embryo cryopreservation. The field has seen much progress during its four-decade history, progress driven predominantly by research in humans, cows, and mice. Two basic cryopreservation techniques rule the field--controlled-rate freezing, the first to be developed, and vitrification, which, in recent years, has gained a foothold. While much progress has been achieved in human medicine, the cattle industry, and in laboratory animals, this is far from being the case for most other mammals and even less so for other vertebrates. The major strides and obstacles in human and other vertebrate oocyte and embryo cryopreservation will be reviewed here.

••
TL;DR: This review updates information relating to the cryopreservation of goat semen, with emphasis on the peculiarities specific to the species.
382 citations
••
TL;DR: A review is given on the use of frozen-thawed semen for artificial insemination (AI) in spontaneous and induced oestrus and factors influencing the fertility.

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: In this review, the main features of folliculogenesis are summarized and compared among species, and superovulation is still an efficient technique to obtain progeny from genetically valuable females.
