Nonsurgical Embryo Recovery as a Feasible Tool for Supporting Embryo Biobanks of Locally Adapted Brazilian Sheep and Goats.

This study assessed the outcomes of nonsurgical embryo recovery (NSER) after superovulation (SOV) in five locally adapted Brazilian breeds of sheep and goats. The objective was to evaluate the feasibility and efficiency of using SOV combined with a less-invasive embryo collection technique for supplying the Brazilian animal gene bank with germplasm from specific genotypes of interest. Morada Nova ( = 20), Santa Inês ( = 20), and Somalis ( = 20) ewes received an intravaginal progesterone (330 mg) device for 9 days, while Canindé ( = 15) and Moxotó ( = 15) goats received an intravaginal medroxyprogesterone acetate (60 mg) device for 6 days.
