DEFICIENCY GENERAL SYMPTOMS

• Manganese deficiency in all species leads to retarded growth, skeletal abnormalities, ataxia of the newborn and reproductive failure. Low manganese diets for cows and goats have been reported to depress or delay oestrus and conception, and to increase abortion.
• In pigs lameness is a symptom due thickening and shortening of bones of the legs. Other abnormalities associated with deficiency include impaired glucose utilization and a reduced vitamin K induced blood clotting response.
