Introduction:
Lactation tetany is a metabolic neurotic disorder of mares, and also known as eclampsia or transit tetany or Hypocalcaemia. the occurrence of lactation tetany is common in recently foaled, due to a rapid reduction in serum ionic calcium levels and excretion of calcium in milk, which shows abnormal behaviours with similar clinical signs of tetany.
It occurs in mares that receive poor roughage, low calcium diets, and sometimes due to gastrointestinal diseases that cause poor calcium absorption and prolonged physical work or exercise (stress of work) or transport. The deficiency of vitamin D also interferes with calcium absorption from the intestines.
The present case was reported to be a recently foaled pony with the primary complaint of reluctance to walk, and stiff gait, the animal was under dry forages and concentrate feeds.
