Abstract
Abstract In Al-sulaumania college of Agriculture, through 2005, an experiment was conducted on eighty-one-day-old Ross 308-strain broiler chickens, that were fed diets containing 0 or 4 ppm T-2 toxin from 1 to 42 days of age. Mixture of 0.125% Sodium bentonite , 0.125% hydrated sodium calcium aluminosilicate (HSCAS) and 0.125% mycofix (∑ 0.375%), were added to the basal diet, as fed basis to determine the effects of these additives against T-2 toxicosis. Broiler chickens were divided into 4 groups of 10 with similar initial weights. Each experimental diet was replicated 2 times during 42 days. Body weight gain, , feed conversion ratio, weekly feed intake, relative weight of organs (liver, , heart, Kidney, proventriculus and gizzard, thymus, bursa of Fabricius and spleen ); blood picture ;stress factor; total serum protein ; lactate dehydrogenase, Alanin aminotransferase, aspartate aminotransferase were recorded. The results showed that body weight gain, , feed consumption and feed conversion ratio, were significantly lesser (P<0.05) with diet containing T-2 alone. Relative weight of pancrease, liver and kidney in chickens fed diet containing T-2 alone were significantly greater ,while the relative weights of thymus, bursa of Fabricius and spleen were significantly lesser with diet containing T-2 alone. Red blood cells, white blood cells, haemoglobin, packed cell volume, lymphocytes, heterophils were significantly lesser , while stress factor was significantly greater with diet containing T-2 alone . Blood enzymes show significant , increase in LDH level, but reduction in both ALT and AST in T-2 fed chicks , compared with other groups. On the other hand, chickens receiving mixture additives to the T-2 toxin contaminated diet showed an increase in body weight gain, feed consumption and improving feed conversion ratio; restore relative weights of internal organs; improve blood picture and stress factor; return serum total protein concentration and serum enzymes to control values, when compared to birds fed diet containing T-2 alone. From above it is evident that the addition of the above compounds made an improvement against all negative effects of T-2 toxin in broiler chickens.
