Efficient Generation of Myostatin Knock-Out Sheep Using CRISPR/Cas9 Technology and Microinjection into Zygotes
While CRISPR/Cas9 technology has proven to be a valuable system to generate gene-targeted modified animals in several species, this tool has been scarcely reported in farm animals. Myostatin isExpand

Oocyte developmental competence is improved by relatively greater circulating progesterone concentrations during preovulatory follicular growth.
This study evaluated the effect of progesterone priming during follicular growth on oocyte competence to undergo oocyte cleavage and embryo development in sheep. Two experiments were performed on aExpand

Serum progesterone concentrations during FSH superstimulation of the first follicular wave affect embryo production in sheep.
The aim of the present study was to evaluate the effect of serum progesterone concentrations during the superstimulatory treatment of the first follicular wave on fertilization rate and embryoExpand

Embryo survival and birth rate after minimum volume vitrification or slow freezing of in vivo and in vitro produced ovine embryos.
The objective was to evaluate pregnancy outcomes and birth rate of in vivo derived vs. in vitro produced ovine embryos submitted to different cryopreservation methods. A total of 197 in vivo and 240Expand

Time of ovulation and pregnancy outcomes obtained with the prostaglandin-based protocol Synchrovine for FTAI in sheep.
The objective of the present study was to determine the ovarian response induced with the prostaglandin-based protocol Synchrovine (two doses of PGF2α given 7 d apart), as well as the fertility afterExpand
