This study examined the effects of cytoplasmic volume on the developmental competence of hand-made cloned buffalo embryos. Two different cell types, that is, buffalo fetal fibroblast (BFF) and buffalo embryonic stem (ES) cell-like cells were taken as donor cell and fused with one, two, or three demicytoplasts to generate embryos with decreased, normal (control), and increased cytoplasmic volume. Using BFF as a nuclear donor, the cleavage rate was similar in all the groups (p > 0.05), but the blastocysts rate was significantly lower (p < 0.05) for embryos generated with decreased cytoplasmic volume. Using ES cell-like cells, the cleavage and blastocyst rate with increased cytoplasmic volume was significantly higher (p < 0.05) compared that with reduced cytoplasmic volume. Blastocysts produced from embryos having increased cytoplasmic volume had significantly higher (p < 0.05) cell number than normal (control) embryos in both BFF and ES cell-like cells groups. Pregnancies were established in all the groups except for the embryos reconstructed with decreased cytoplasmic volume. The pregnancy rate was almost double for embryos reconstructed using increased cytoplasmic volume compared to that with the controls. Most of the pregnancies aborted in the first trimester and one live calf was delivered through Caesarean, which died 4 h after birth.
