Development And Permeability Of Equine Blastocysts, Brittany Reshel Scott

LSU Master's Theses

Equine embryo cryopreservation is unsuccessful in larger, more easily collected, day-7 embryos. It is imperative that methods to successfully cryopreserve large equine embryos or develop reliable methods to determine embryo size before collection. Therefore the objectives for this study were to quantify the amount of tritiated glycerol that would permeate various sizes of equine embryos and to determine if circulating progesterone concentration was correlated with in utero embryo size. Mean embryo diameter (± SEM) across treatments (1.4M and 3.4M tritiated glycerol) was 696.5µm ± 108.6µm and 925.9 µm ± 214.1µm, respectively and were not different (P=0.44). The percent permeation for …
