Captopril na produção in vitro de embriões bovinos? / Captopril in production in vitro of embryos bovine?

ABSTRACT

Objective to evaluate the effect of captopril in vitro production of bovine embryos. 472 COCs were usedfrom abattoir ovaries, which were screened, sorted and selected in grades I and II, and submitted to the PIVprocess. The IVM treatments were added in the following concentrations T1 - control; T2 - 5 mM of captopril;T3 - 10 uM of captopril; and T4 - 15 captopril uM, the COCs were subjected to IVM, IVF CIV. The results showthat there was no statistically significant difference (P > 0.05) between treatments during maturation. Thevariables studied were cleavage and blastocyst rates. The captopril supplementation did not improve (P > 0.05)G1 cleavage rate - 61.84%; G2 - 71.00%; G3 - 68.87%; and G4 - 56.90%. Supplementation of 20μM ofcaptopril influenced the amount of viable embryos.(AU)
