Among the toxin treated groups, the AF group revealed significant (P<0.05) difference during the second week only, T-2 group revealed significant (P<0.05) differences during the third week to sixth week, while AF-T-2 group revealed significant (P<0.05) differences from first week till 13th week except 8th and 9th week. There was a significant (P<0.05) decrease in the body weight gain in toxin fed birds when compared to control birds. Significant (P<0.05) differences in feed conversion were observed between the control and toxin treated groups. Significant (P<0.05) decrease in feed conversion efficiency ratio was observed in the toxin treated groups. Blood samples were collected from each group at the end of 49th and 91st days of trial to study haematological parameters. The PCV, Hb and TEC values decreased significantly (P<0.05) within toxin fed birds when compared to the control. Comparison of means for erythrocyte indices revealed no significant differences between the control and mycotoxin treated groups except MCV which revealed significant (P<0.05) increase between AF and AF-T-2 toxin group showing a macrocytic normochromic blood picture.enVeterinary ScienceArticle
