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.
