An experiment was conducted to study the efficiency of inclusion of neem, turmeric, vitamin E and its combinations on performance and hematological parameters for a period of six weeks with 288 day old Raja II broiler chicks. Basal diet was supplemented with Azadirachta indica (Neem 8g/kg feed), Curcuma longa (Turmeric 2g/kg feed) and Vitamin E 0.2g/kg feed) individually and in combination to form eight test diets. Each test diet was fed ad libitum for 42 days. The result of the present stumdy identified no significant difference in body weight of chicks fed with supplemented diets. Whereas, addition of either neem alone or in combination with turmeric and vitamin E induced significant growth depression in birds compared to control birds. Supplementation of neem, turmeric, Vitamin E and their combinations in broiler diets did not exhibit any significant effect on feed intake and feed conversion ratio during all the weeks of age. The percentage livability of birds under different treatments was statistically non-significant. Hematological parameters in broilers revealed that the hemoglobin concentration in neem fed group was significantly (P<0.05) higher (10.5 g/dL) when compared to turmeric fed group (9.85 g/dL), otherwise diet containing turmeric alone recorded lowest value of hemoglobin. Feeding of neem alone and its combination with turmeric and vitamin E increases significantly PCV values as compared to control. The supplementation of turmeric or vitamin E alone to basal diet did not significantly change PCV values.

Aim: To evaluate the effect of different levels of High Bentonite on growth performance, organ weight and serum biochemistry in broiler fed on diets containing aflatoxin. Materials and Methods: A total of 360 day-old commercial broiler chicks were divided at random into 8 dietary treatment groups of 42 chicks each having 3 replicates. Dietary levels of aflatoxin (0.5 ppm) and High-grade bentonite (0.5, 0.75 and 1.00%) were tested in a completely randomized design manner, forming a total of 8 dietary treatments each with three replicates. Body weight and feed intake were recorded weekly. At 5 wk, six birds from each treatment were sacrificed and liver, kidney, gizzard, pancreas, spleen, bursa of Fabricius and thymus were extracted and weighed. The serum samples were analyzed for total proteins, uric acid, serum albumin, serum globulin and the activities of gamma glutamyl transferase (GGT), alanine amino transferase (ALT) and for antibody titers against Newcastle disease (ND) and infectious bursal disease (IBD) using ELISA technique. Results: A significant (P<0.05) decrease in body weight, feed consumption, relative weights of bursa, thymus, serum protein, anti body titers against NDV and IBDV, and increase in FCR, mortality, relative weight of liver, kidney, and the activity of Gamma Glutamyl Transferase (GGT) was observed. However, the relative weights of gizzard, pancreas, spleen, serum albumin, uric acid and the activity of Alanine Amino Transferase (ALT) were not influenced by inclusion of AF or HGB. Conclusion: The addition of HGB restored the harmful effects of AF on body weight, feed consumption, FCR, mortality, relative weight of liver, kidney, serum protein, IBDV and NDV. Supplementation of high grade bentonite at 1.0 per cent level was found to be beneficial in ameliorating the adverse effects of aflatoxin (AF) in broiler chickens. [Vet World 2013; 6(6.000): 313-317
