Lipid supplementation in donor cows ( <i>Bos taurus</i> ) improves embryo quality

This study aimed to evaluate the effects of linseed supplementation on the <i>in vitro</i> production of embryos subjected to vitrification. Pantaneira cows supplemented with linseed or not (control) were evaluated. The best-quality embryos produced <i>in vitro</i> from both groups were vitrified. Oocyte quality and blastocyst rate did not differ between the groups. However, the rates of vitrifiable embryos and re-expansion at 3 h were higher in the linseed-supplemented group. In conclusion, linseed supplementation in Pantaneira cows improved the quality of embryos produced <i>in vitro</i>.
