Prompt Detail:
The condition in which calves are born without forelegs is called "amelia" in veterinary science. Amelia is a congenital defect that can occur in various animal species, including cattle. It is a rare condition that is often caused by genetic mutations or environmental factors such as exposure to toxins or viruses during fetal development. Calves born with amelia are typically euthanized because they are unable to stand, walk or nurse properly, and are unlikely to survive without significant intervention.
