In these three species, chromosomal abnormalities such as centric fusions or reciprocal translocations cause the formation of embryos with unbalanced karyotypes which do

Its biological function is thought to be one of immunoregulation during pregnancy. The initial stimul

Verband Deutscher Elektrotechnikerhat low pre-luteal levels are required from immediately after oestrus until the level increases to luteal phase levels on Day 4 or 5. In intact, mated ewes, differences in embryo survival were associated with variation in the progesterone profile. Embryo survival was lower in ewes with lower levels

Following insemination, progesterone level increases in pregnant cows with most evidence suggesting a divergence as early as Day 10– between
