At the end of the experiment, 2 birds per replicate were slaughtered and their blood collected for haematology and serum studies. Organ weights of the slaughtered birds were also measured. All data were subjected to analysis of variance. Results showed that among all the organ weights measured, only the liver, lung and proventriculus were significantly (P0.05) influenced by the dietary treatments. Among all the haematological parameters measured, the Mean Cell Haemoglobin Concentration (MCHC), Mean Cell Haemoglobin (MCH), lymphocytes and basophils were significantly (P0.05) influenced by the dietary treatments. For the serum biochemical indices measured, the albumin (ALB) and albumin/globulin (ALB/GLO) ratio were significantly (P&lt;0.05) influenced by the dietary treatments. Generally, there was no deleterious effect of the dietary treatments on the organ weights, haematological and biochemical indices of the broiler chickens. Consequently, it was recommended that FCCSM could be included up to 20% in the diets for broiler-chickens without adverse effects.</p> O. G. Ojambati M. Adegbenro M. A. Adetunji V. A.

Information on the biological methods in aflatoxin mitigation is scanty. Therefore, effect of aflatoxin bio-control method on organ weight and histopathology of layers were investigated. 700 point-of-lay Bovan Nera layers (LC) were randomly allotted to four dietary treatments (Aflasafe maize-based diet AMBD, FF+ toxin binder, Aflatoxin-contaminated diet with toxin binder (ACDTB) and Aflatoxin-contaminated diet without toxin binder (ACDWTB). There were 5 replicates per treatment and experiment lasted for 14 weeks. Histopathology of liver, kidney, spleen, bursa of fabricius and ileum were assessed using standard procedures. Data were analysed using descriptive statistics and ANOVA at α<sub>0.05</sub>. Bursa histopathology of layers fed ACDTWB showed lymphoid depletion and hepatocellular necrosis, while those fed AMBD showed lymphoid proliferation and hepatocellular aggregates. Layers fed ACDTB and ACDWTB showed severe periportal hepatic degeneration and necrosis, with severe periportal cellular infiltration by mononuclear cells. This was classified as ranging from moderate to severe congestion of the parenchyma as observed in the lungs. The submucosal lymphoid population was expanded in the ileum of layers fed AMBD and those fed FF+toxin binder showed severe villi atrophy. Aflasafe maize-based diet enhanced integrity of the organ weights and histopathology of layers. The use of bio control method of aflatoxin mitigation (aflasafe) in poultry diet is recommended.</p> Olayinka Abosede Ojo ##submission.copyrightStatement## 2020-05-27 2020-05-27 9 19
