What is the bovine maternal recognition of pregnancy factor? Unidentified Prolactin Interferon τ Progesterone Oestrogen Please select an option Incorrect. In the mare, the conceptus does produce proteins to effect the recognition of pregnancy, but specific roles are unknown. Cattle blastocysts produce a small protein called bovine interferon tau (BIFN-τ)from day 13-21 after ovulation. It binds to the uterine endometrium and inhibits the synthesis of oxytocin receptors. As a result, there is no production of the luteolytic factor PGF2α and the corpus luteum is maintained. WikiVet Article: maternal recognition of pregnancy. Incorrect. The lifespan of the corpora lutea in a pregnant queen is extended to ~60 days by the action of pituitary prolactin. There is no need for a conventional 'maternal recognition of pregnancy'.
