It is an essential part of coenzyme A. It can adjust the metabolism of protein, carbohydrate and fat, preserve the mucosa on the skin surface and shine of the hair (or feather), and moreover prevent diseases. It is especially indispensable to the growth, fat synthetize and catabolism of poultry, livestock and fishes. Deficiency Symptoms:  The deficiency of D-Calcium Pantothenate will cause poultry and livestock to grow slowly, hinder their reproduction, lower their adaptability. Main symptoms: rough skin, reluster or loss of hair or feather, scabby crusts appear round the corner of the eyes; disorder of digestion, loss of appetite, diarrhea; low rate of hatch ability and high embryo mortality; scabby crusts over affected areas such as the corners of the month or beak, around the eyes, behind the ears and occasionally on the feet. Also a deficiency can lead to unsteady movements, which are recognized particularly in pigs as "goose-stepping". Storage: to keep in a dry, cool and off-light place.
