title: The effect of horse serum on in vitro development of porcine parthenogenetic embryos.
abstract: The objective of this study was to examine the effect of different sera and serum-like substances on the preimplantation development of porcine parthenogenetic embryos. Chemically activated (calcium ionophore A23187+cytochalasin B) pig oocytes were pre-cultured for five days. On day 5, the parthenogenetic embryos were treated with porcine follicular fluid (PFF), fetal bovine serum (FBS), horse serum (HS) or porcine serum albumin (PSA), and were cultured two more days. Horse serum was found to be the most effective protein source in enhancing parthenote development judging by blastocyst formation and hatching. Next, three different concentrations of HS (10, 20 and 30%) were used to determine the optima HS concentration needed to improve the development of porcine parthenogenetic embryos. All HS concentrations increased the blastocyst cell number and decreased the incidence of blastocyst apoptotic cells with 20% being the most effective. In conclusion, horse serum enhanced parthenogenetic embryo development and the quality of porcine parthenogenetic embryos.
