ARTICLE young chick) by bacteria in the caeca and large intestine. As absorption of Vit B2 occurs from the small intestine, this is of no use to the bird, therefore coprophagy is the important source. Bacterial content and vitamins are especially high in ‘caecotroph’ therefore caecotrophy is common in chickens. Causes of Deficiency: In chickens, high levels of dietary energy, fat or protein with inadequate levels of vitamin B2 increase the riboflavin requirement.Presence of antagonists of vit B2 in the feed, such as mycotoxins, mainly aflatoxin interfere with absorption or body transport. Deficiency Symptoms: Reduced growth rate, Poor efficiency of food utilization, Degeneration of the peripheral nerves, particularly affecting the sciatic nerve, Leg paralysis and inability to extend the digits, producing the condition called ‘curledtoe paralysis’, Reduced egg production, Reduced hatchability with peak embryonic deaths around mid-incubation, Hatched chicks may be dwarfed with shortened limbs, poor feathering and leg paralysis and improper growth of the down (very soft feathers), giving it blunted appearance (club-shaped appearance) known as ‘clubbed down’. Treatment: Adequate level should be incorporated in the ration @ 5 mg per chicken and @ 15mg per hen per day. Vitamin B6 (Pyridoxine): It is a general term, which includes 3 naturally occurring substances i.e Pyridoxine, Pyridoxal and Pyridoxamine. Causes of Deficiency: Diets high in total protein or containing unbalanced protein and inadequate levels of Vitamin B6 markedly increase the requirement for Vit B6. Deficiency Symptoms: Reduced appetite, Slow growth, Weakness, Poor feather growth, Anemia, Inability to co ordinate muscle movements (ataxia), Chondrodystrophy, Nervous symptoms, Jerky nervous movements of the legs when walking, Convulsions, During convulsions chick may run aimlessly, flap their wings and fall to their slides, or roll completely over on their backs, Marked reduction of egg production and hatchability, Decreased feed consumption and Loss of weight and death. Nicotinic Acid (Niacin): It is synthesized by bacterial action in caecum and rectum and chickens are able to synthesize 1mg of Nicotinic acid from 45 mg of dietry Tryptophan. Causes Of Deficiency: Inadequate levels of nicotinic acid in the feed, Insufficient absorption, Stress and Errors in mixing. Deficiency Sumptoms: Loss of appetite, Poor growth, Skin and feather disorders, Inflammation of the mouth, Dermatitis, Poor feathering, Enlargement of the hock joints of the legs and Chondrodystrophy. Treatment: Supplementation of feed with Nicotinic acid at @ 40-50mg per chicken. Pantothenic Acid: Causes Of Deficiency: Low pantothenic acid in breeder feed and inadequate level in chick starter feed. Deficiency Symptoms: Slow growth, Poor feathering, Weakness, Ataxia, Skin lesions at the corners of the mouth, Swollen and encrusted eyelids, Cracks and haemorrhages in the skin of the feet and toes, Fatty liver and atrophy of thymus and bursa, Embryos from Pantothenic acid deficient hens have high mortality characterized by oedema. Haemorrhages and poor feathering. Treatment: Pantothenic acid deficiency can be completely cured by oral treatment or injection with the vitamin @ 10-20 mg per chick per day. Biotin: Causes Of Deficiency: Conditions which decreases intestinal synthesis,such as antibiotics and diarrhea, Presence of biotin binders and antagonists in feed such as mycotoxins mainly aflatoxins and Inadequate levels of biotin in the feed. Deficiency Symptoms: Defective feathering, Periocular dermatitis, Encrustations and fissures in the angles of the beak and eyelids and on the foot pads and toes, Reduced growth, Dry, encrusted, fissured, haemorrhagic skin on the feet, poor feathering, deformed ‘parrot’ beak and chondrodystrophy, Shortened bowed legs with enlarged hocks, Reduced egg production and Deformed chick embryo. Treatment: Injection or oral administration of biotin. Control: Supply of adequate levels of biotin in the feed, avoiding excessive use of antibiotics, elimination of biotin antagonists in the feed and assay of feed samples to determine the levels of biotin at frequent intervals. Folic Acid: Causes of Deficiency: Inadequate level of folic acid in the feed due to pelleting and feeding of solvent extracted soyabean meal low in folic acid content. Deficiency Symptoms: Defective synthesis of DNA & RNA, resulting in reduced cell division, Anemia leukopaenia, 60 <strong>November</strong>, <strong>2018</strong>
