Original text on this topic:
Drops of milk on the teats (waxing?) are seen as long as 3 weeks before partus. The onset of udder development is sudden and massive and is seen 2-3 days before parturition. Parturition lasts 0,5-1 h and no complications have been recorded to date. One cow currently pregnant, has developed a vaginal prolapse. Cows come on heat ca 1,5 years after calving when she allows service.
