The employment of protein-free medium for the culture of ovine embryos collected at the 1-2 cell stage from superovulated ewes was investigated. For this purpose sheep zygotes were randomly allocated in four treatment groups: T1) CZB medium + bovine serum albumin (BSA) on sheep oviductal monolayer (SOM), T2) CZB + polyvinyl alcohol (PVA) + SOM, T3) CZB + PVA + SOM supplemented with inositol (I) and serine (S), T4) TCM 199 + 10% fetal calf serum + SOM. Standard culture conditions were 2 ml of medium in 35 mm Petri dishes, under 5% CO2 in air at 39 degrees C. The percentages of morulae and blastocysts were recorded after 4 and 7 days of culture. After 4 days of culture there was no significant difference (P > 0.05) in the percentage of morulae between embryos cultured in T1 (86%), T2 (85%), T3 (88.8%), and T4 (87.5%). After 7 days the percentages of blastocysts were T1 (70%), T2 (50%), T3 (55.5%) and T4 (46.8%). These data suggest that a protein-free medium, CZB + PVA and CZB + PVA + I + S, can support ovine preimplantation embryo development in vitro; however CZB medium supplemented with BSA enhances development to blastocyst.
