Lipid supplementation in donor cows (Bos taurus) improves embryo quality.

This study aimed to evaluate the effects of linseed supplementation on the in vitro production of embryos subjected to vitrification. Pantaneira cows supplemented with linseed or not (control) were evaluated. The best-quality embryos produced in vitro 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 in vitro.
