Abstract

Domestic cat oocytes were cultured either in Waymouth MB 753/1 Medium (WAY) or in Eagle's Minimum Essential Medium (MEM) containing FSH, LH and estradiol-17β and supplemented with one of the following: 5% fetal calf serum (FCS); 4 mg/ml bovine serum albumin (BSA); or 3 mg/ml polyvinylalcohol (PVA, a non-protein control). The oocytes were evaluated for: nuclear maturation after 48 hours of culture (in vitro maturation, IVM); fertilization and cleavage 24 to 30 hours postinsemination (in vitro fertilization, IVF); and early embryo development 48 hours postinsemination. Maturation rates were similar (P>0.05) for WAY + BSA (29.4%), MEM + BSA (46.7%) and MEM + PVA (43.3%), but were different (P0.05) for WAY + BSA (51.4%, 30.5%), MEM + BSA (45.8%, 40.1%) and MEM + PVA (56.1%, 37.4%) and were greater (Pin vitro can proceed in this species in the absence of supplementary protein.
