The research was conducted to determine the effect of various inclusion level of enzyme supplemented rumen digesta in broiler diets. A total of one hundred and eighty (180) day old un-sexed cobbs from Zatec were used for the study. The chicks were randomly allocated into five (5) dietary treatment groups of thirty six (36) birds per treatment and replicated four times with nine (9) birds per replicate in a Completely Randomized Design (CRD). Five experimental diets were formulated with cattle rumen digesta at various inclusion levels 0%, 5%, 10%, 15% and 20% for T1, T2, T3, T4 and T5 respectively. Data were collected on carcass yield and internal organs characteristics, heamatology and biochemical indices of broiler chickens. Carcass and internal organs parameters were also not significantly different (p>0.05) across the dietary treatments except the heart and gizzard which indicated a significant difference (p<0.05) among treatment groups. Heamatological parameters such as packed cell volume (PCV), red blood cell (RBC), hemoglobin (Hb), mean corpuscular volume (MCV}, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) were not significantly difference (p>0.05) across all the treatment groups. For the biochemical indices, glucose, albumin, cholesterol, Creatinine, urea were not significantly (P>0.05) difference except total protein showed significance (p<0.05) among treatment means. It could therefore be recommended that rumen digesta could be included in the diet of broiler chicken up to 20% without detrimental effect on their carcass characteristics and blood profile.
