questionnumber="6"
question="What is the bovine maternal recognition of pregnancy factor?"
choice3="Interferon τ"
choice5="Oestrogen"
choice2="Prolactin"
choice1="Unidentified"
choice4="Progesterone"
correctchoice="3"
feedback3="'''Correct!''' 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. [[Gestation -Maternal Recognition of Pregnancy - Anatomy & Physiology#Ruminants |WikiVet Article: maternal recognition of pregnancy]]."
feedback5="'''Incorrect.''' The pig conceptus produces oestradiol as the signal for maternal recognition of pregnancy. 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. [[Gestation -Maternal Recognition of Pregnancy - Anatomy & Physiology#Sow|WikiVet Article: maternal recognition of pregnancy]]."
feedback2="'''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'. 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. [[Gestation -Maternal Recognition of Pregnancy - Anatomy & Physiology#Queen|WikiVet Article: maternal recognition of pregnancy]]."
feedback1="'''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.
