Abstract: Two experiments were carried out to examine the effects of different factors on the survival of split sheep embryos. In Experiment 1, embryos collected on Day-6, Day-7 or Day-8 were bisected and transferred into recipient ewes in pairs. The proportions of Day-6, Day-7 and Day-8 demi-embryos developing to lambs were 26% (), 30% () and 32% (), respectively. Replacement of bisected late morula to expanded late blastocyst stage embryos into zonae did not affect their survival rate (P>0.5). The proportion of demi-embryos developing to lambs in recipients with two or more ovulations was higher (35%, ) than in recipients with a single ovulation (21%, ; P<0.05). In Experiment 2, Day-6 embryos were split with or without exposure to 0.25 M of sucrose and were transferred into recipients in pairs or singly. Exposure to 0.25 M of sucrose decreased the proportion of split embryos developing to lambs compared with that of the controls (31%, vs 49%, ; P<0.05). The effects of the number of demi-embryos transferred or the stage of development on the survival rate were not significant (P>0.05). The number of lambs born per original embryo was the highest when the embryos were split without exposure to sucrose and transferred into recipients singly (106%, ). |
