ArticleItem Open Access Aflatoxin B1 Induced Pathomorphological Changes in Lymphoid Organs of Broilers(Indian Journal of Veterinary Pathology, 2011) Arulmozhi, A.; Varghese, Koshy; TANUVASThe present study reports the pathomorphological changes in lymphoid organs induced by aflatoxicosis in broiler chicken. One hundred and eighty day-old broiler chicks were obtained and divided into six groups of thirty birds each (Group I, II, III, IV, V and VI) and they were given 0, 20, 40, 60, 80 and 100 ppb of AFB1 respectively. Severe lymphoid depletion along with decreased bursa weight were recorded in Group IV, V and VI. Spleenic atrophy and lymphoid depletion was noticed in all the groups except in Group V and VI on 45th day. Thymus revealed lymphoid depletion in all the groups throughout the experimental period.ArticleItem Open Access Aflatoxin Residues In Tissues Of Broiler Chicken(Indian Veterinary Association, 2002-09) Arulmozhi, A.; Varghese, Koshy; Isma, P.K.; Peethambaran, P.A.; Ramachandran, K.M.; TANUVASAflatoxins are harmful chemicals produced by Aspergillus flavus and A. parasiticus that grow on a variety of substrates including plants, cereals, pulses and fruits. In birds and animals, aflatoxicosis usually occur by direct consumption of aflatoxin contaminated feed.ArticleItem Open Access Aflatoxin induced Hepatopathy in Broiler Chicken(Indian Journal of Veterinary Pathology, 2007) Arulmozhi, A.; Varghese, Koshy; Ismail, P.K.; Peethambaran, P.A.; TANUVASGross, histo-pathological and ultra structural changes in the liver of broiler chicken induced by feeding graded levels of aflatoxin at the rate of 0,20,40,60,80 and 100 ppb in the feed from day one to 45th day were studied. Intensity of the lesions like vascular changes. bileduct hyperplasia, portal fibrosis and mononuclear lnfilltratlons were directly related to the level of toxin in the feed and duration of exposure, with most severe changes at 80 and 100 ppb on the 45" day of experiment. Residual toxin in the liver win estimated and found to be below the standard set by FDA and FAO.ArticleItem Open Access Haemato-Biochemical Changes In Experimental Aflatoxicosis in Broiler Chicken(Indian Journal of Veterinary Pathology, 2000) Arulmozhi, A.; Varghese, Koshy; Ismail, P.K.; Peethambaran, P.A.; TANUVASA-(tilatoxin and their toxic metabolites are known to cause degenerative, immunosuppressive and carcinogenic effects. Aflatoxicosis in poultry produces liver damage. Hepatic injury is associated with significant serum biochemical and haematological changes. The present study records the effect of various levels of aflatoxin B1, on haematological and serological changes, in broilers fed on diet containing aflatoxin B1 for 6 weeks.
