VITAMIN Bi DEFICIENCY

431.In birds, vitamin B, (thiamine) deficiency is clinically and morphologically manifested with paralysis of limbs and muscle atrophy, beginning from the flexors of toes and ascending towards the extensors of legs, wings and the neck. The chickens acquire a specific posture with flexed legs and the head drawn back (stargazing). As hypovitaminosis B, causes a severe anorexia, thiamine supplementation to the drinking water is advised until the recovery of acute deficiency and thereafter, the vitamin could be added to the forage.
