Q

Maternal reco of pregnancy

Please indicate, what of the below statements related to the maternal recognition of pregnancy is incorrect.
A) Some hours after hatching from the zone pellucida the equine embryo starts an intensive longitudinal growth. (elongation)
B) Some hours after hatching from the zona pellucida the ruminant and porcine embryos start an intensive longitudinal growth (elongation)
C) In ruminants the embryonic signal of maternal recognition of pregnancy is a protein belonging to the interferon family (interferon-1)
D) In pig the embryonic signal in maternal recognition of pregnancy is estrogen-based.
E) In mares the embryonic signal of maternal recognition of pregnancy is a protein, however its effect is combined/completed also with some estrogens of embryonic origin.

Puberty means

A

When the animal has mature sexual organs and starts cycling

The physiologic events leading to puberty are analogous to those regulating the onset of the breeding season.

23
Q

What is the main hormonal factor of delayed resumption of cyclic ovarian activity caused by energy deficit?
