| The present study aimed to diagnose early embryonic death in 128 mares. Blood samples were collected at the 4th, 7th, 10th, 13th, 16th, 19th, 21st and 30th day after ovulation and the diameter of the corpus luteum was measured. The diameter and characteristics of the embryonic vesicle were evaluated by ultrasonography. Microbiology, cytology and histopathology were carried out in mares with embryonic death. Plasma oestrogen and progesterone concentration were measured by radioimmunoassay. From 128 mares, 17 (13.28%) showed early embryonic death. The embryonic losses took place at 19 days of pregnancy in 47.05% and at 21 days of pregnancy in 29.4% of the mares. The diameter of the corpus luteum in the mares that maintained pregnancy was similar to those... |
