Three-day Progesterone Priming Protocol for Breeding Goats During Anestrus/transition

Many traditional protocols used to breed goats during anestrus and transition call for extended periods of progesterone priming lasting anywhere from nine to 21. Work in our laboratory has shown that four-cell embryos can be reliably produced outside of the breeding season using a three-day progesterone priming protocol. We hypothesized that this protocol could be modified to induce estrus for breeding goats during anestrus and transition. The aim of this study was to determine the efficacy of this short progesterone priming protocol to induce estrus and produce viable pregnancies. [...]
