DOIAbstract
The study was performed to evaluate whether the use of hCG 7 days after synchronized oestrus in Morada Nova ewes would increase the number and size of corpora lutea. In conclusion, 300 IU of hCG injected 7 days after synchronized oestrus is effective to increase the number of corpora lutea and in the size of luteal tissue. Despite indications of a favourable effect on luteal dynamics, the effects on progesterone production and conception rate need to be examined.Proceedings of the Annual Conference of the International Embryo Technology Society (IETS), New Orleans, Louisiana, 2018
