Using a novel in vivo model considering a low developmental competence embryo (demi-embryo) and a subnormal fertility recipient (lactating high-yielding dairy cow), this experiment evaluated the effect of human chorionic gonadotrophin (hCG) treatment at embryo transfer (ET) on embryonic size at implantation, embryonic survival and recipient plasma progesterone (P-4) and bovine pregnancy-specific protein B (PSPB) concentrations until day 63 of pregnancy. Embryos were bisected and each pair of demi-embryos was bilaterally transferred to recipients (n=61) on day 7 of the oestrous cycle. At ET recipients were randomly assigned to treatment with 1500IU hCG or to untreated controls. Higher (p
