Six-legged Calf. This six-legged Holstein calf was stillborn at term to a pluriparous cow. The delivery required only minimal assistance. The head, tail and four other limbs appeared normal. The extra set of hindlimbs narrowed as they approached the pelvis and were attached near the head of right femur.Roodzant JP (2007)

Cyclops. Cyclops found at the slaughter house. This calf weighed 60 kg, had long hair and did not have a pituitary gland, suggestive of postmaturity as a result of failure by the calf to initiate parturition.Drost M (1968)

Fetal Giant. Lateral view of the skull of a postterm (12 months) fetal giant showing a cerebral hernia. While the brain was defective, the pituitary gland was normal in this Guernsey fetus, yet the fetus did not initiate parturition. The hypothalamus may have been deranged.Roberts SJ (1973)

Perosomus Elumbis. Perosomus elumbis; complete lack of development of the hindquarters.Roberts SJ (1986)

Pulmonary Hypoplasia with Anasarca. Posterior view of a Maine-Anjou fetus with Pulmonary Hypoplasia with Anasarca (PHA). The huge bilateral swelling is due to fluid, not muscle. The scrotum is the size of a 2-year old bull and is also filled with fluid. The calf was delivered by cesarean section.Kaiser L (2007)

Achondroplasia (Bulldog Calf). Achondroplastic term Ayrshire calf (bulldog calf). [size of the square tiles is 15 cm].Roberts SJ (1986)

Pulmonary Hypoplasia with Anasarca. Facial view of the enlarged edematous head with swollen tongue, of a newborn PHA calf. The ears are flat and nearly invisible. The eyes are mere slits.Kaiser L (2007)

PHA Severe Edema of the Head. Massive swelling of the head of a calf born with Pulmonary Hypoplasia Achondroplasia. The ears are difficult to identify and the eyes are mere slits.Kaiser L (2012)

Schistosoma Reflexus

Partial Delivery - Schistosoma Reflexum. Cow in the process of delivering a calf with Schistosoma reflexum. The extra-abdominal viscera of the fetal monster protrude from the vulva. The gauge of the fetal intestines readily distinguish them from potential maternal viscera. The ankylosed vertebral column frequently makes a vaginal delivery, without the benefit of a partial fetotomy, difficult.Roberts SJ (1973)

Schistosoma Reflexum - 70-Day Fetus. A 70-day old fetus with Schistosoma reflexum (incidental finding as a slaughterhouse specimen).Drost M (1979)

Schistosoma Reflexum - 70-Day Fetus. A 70-day old fetus with Schistosoma reflexum illustrating the early vertebral defect (incidental finding as a slaughterhouse specimen).Drost M (1979)

Vertebral Column Schistosoma Reflexum. Close-up of the defective vertebral column of a 70-day old fetus (incidental finding as a slaughterhouse specimen).Drost M (1979)

Schistosoma Reflexum - Holstein Neonate. Schistosoma reflexum in a newborn Holstein calf. The vertebral column has doubled back on itself and is ankylosed. Recommended method of delivery is by fetotomy after severing the umbilical cord, if the calf is alive.Roodzant JP (2007)

Schistosoma Reflexum - Guernsey Fetus. Schistosoma reflexum in a newborn Guernsey calf. The vertebral column has doubled back on itself and is ankylosed. Viscera are distended with fluid.Roberts SJ (1973)

Schistosomus Reflexus in a Holstein Cow. A term Schistosomus reflexus calf was delivered by traction per vaginam. These fetal monsters are not large, per se, but they are deformed. This calf presented with a vertebral column that doubled back on itself.Shipley C (2006)

Schistosomus Reflexus / Fetal Death. The everted abdominal wall has been opened up to show the head on the upper left. The tip of the tongue is sticking out of the right corner of the mouth. The fetus is completely turned back on itself and is compacted.Wuenschmann A (2012)

Fetal Anasarca. Generalized massive edema of all parts of the body (anasarca) of the fetus. As a rule these fetuses are aborted. Most of these fetuses are the result of an autosomal recessive gene.Kearns BM (2013)

Two-Headed Calf. This two-headed calf is an incomplete set of twins. This bicephalic calf had one body. The conformation may lead to dystocia. Vaginal delivery is effected by partial fetotomy if the calf is dead, or after severance of the umbilical cord.Utrecht (1976)

Partial Fetotomy. The head of this term bicephalic calf was reduced in size by making two cuts with the fetatome, to enable vaginal delivery.Leduc F (2007)
