Abstract
Methods for the efficient production of cloned porcine fetuses/piglets following the production of cloned embryos, including culture of the embryos for extended periods prior to transfer of the embryos into the uterus of the recipient. Transfer can be accomplished surgically or through less-invasive laparoscopic or non-surgical transfer.
Claims25
A method for the production of cloned piglets comprising the steps of:
- (b) culturing cloned pig embryos for a period of time;
- (c) transferring the cultured embryos to suitable recipients;
- and
- (d) allowing the transferred embryos to develop to term, wherein the recipient farrowing rate is greater than 30% and the average litter size is at least 4 piglets.
1 more element
A method for the production of cloned piglets comprising the steps of:
- (a) culturing cloned pig embryos for more than 76 hours;
- and
- (c) transferring the cultured embryos to suitable recipients by laparoscopy or non-surgical techniques;
- and
- (d) allowing the transferred embryos to develop to term.
2 more elements
A method for the production of cloned piglets comprising the steps of:
- (a) culturing cloned pig embryos for at least 18 hours;
- (c) transferring the cultured embryos to suitable recipients using non-surgical or laparoscopic techniques;
- and
- (d) allowing the transferred embryos to develop to term, wherein the recipient farrowing rate is greater than 30% and the average litter size is at least 4 piglets.
