The use of exogenous progesterone in sheep superovulation protocols influences the percentage of viable embryos. Author(s): FONSECA, J. F. da The success of multiple ovulation and embryo transfer strongly depends on superovulatory protocols (SOV) success which has shown inconstant. SOV protocols have used different sources of progestogen wi... ... Repository: BDPA Publication year: 2020
Cervical relaxation protocol without estradiol benzoate is efficient to allow transcervical uterine flushing in Dorper ewes. Author(s): FONSECA, J. F. da This study evaluated the efficiency of non-surgical embryo recovery (NSER) with cervical relaxation protocol using different doses of estradiol benzoate (EB) in ewes. A total of 36 pluriparous Dorper... ... Repository: BDPA Publication year: 2020
