Pantothenic Acid Deficiency (vit B-5)
(excerpt)
The major lesions of pantothenic acid deficiency for poultry appear to involve the nervous system, adrenal cortex and skin (Scott et al., 1982). Pantothenic acid deficiency reduces normal egg production and hatchability.......In chickens a decline of growth is followed by decline in feed conversion and retardation of feather growth. Plumage becomes rough and ruffled, and feathers become brittle and may fall; next dermatitis rapidly develops in chicks. Corners of the beak and the area below the beak are the worst affected,
but the disorder is also observed in feet. Outer layers of skin between toes and on bottoms of feet peel off, and small cracks and fissures appear. In some cases skin layers of feet thicken and cornify, and wart-like protuberances develop on balls of the feet. The foot problem is usually exacerbated by bacterial invasion of the lesions. ..."
...I
would havesuggested giving three to four drops of POLYVISOL (liquid childrens vitamins) for a week daily then slowly tapering off and see if this does not help
HOWEVER I just looked at the ingredients and see it does not contain vit B5 (pnatothenic acid) so suggest you find one that does include this and the rest of the ingredients listed for POLYVISOL (be careful with a
multivitamin as it will often contain excesss amounts of copper or such which may be toxic,,,the vitamins in the polyvisol are ok except in this case where you might need the B5) here are the rest of the ingredients of POLYVISOL (as you see >B5 is not listed):
Vitamin A 1500 IU
Vitamin C 35 mg
Vitamin D 400 IU
Vitamin E 5 IU
Thiamin (B1) 0.5 mg
Riboflavin (B2) 0.6 mg
Niacin (B3) 8 mg
Vitamin B6 0.4 mg
Vitamin B12 2 ug
a good supplemental poultry vitamin such as AviaCharge 2000 or RoosterBooster vitamins regularly might be indicated also. (Here is alsoThe page below on Biotin deficiency)
