This study investigated the effects of varying levels of cattle rumen digesta supplemented with 0.025% Fullzymes on carcass characteristics and blood profile of broiler chickens. A total of 180 unsexed day-old Cobb chicks were randomly assigned to five dietary treatment groups, each comprising 36 birds with four replicates of nine birds per replicate, in a Completely Randomized Design (CRD). The experimental diets included 0% (T1), 5% (T2), 10% (T3), 15% (T4), and 20% (T5) inclusion levels of rumen digesta. Data were collected on carcass yield, internal organ characteristics, hematological parameters, and serum biochemical indices. Results showed no significant differences (p > 0.05) in overall carcass traits and most internal organ weights across treatment groups, except for the heart and gizzard, which exhibited significant variation (p < 0.05). Hematological indices, including packed cell volume (PCV), red blood cell count (RBC), hemoglobin concentration (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC), were not significantly affected (p > 0.05) by dietary treatments. Similarly, biochemical parameters such as glucose, albumin, cholesterol, creatinine, and urea remained statistically unchanged (p > 0.05), while total protein levels showed a significant difference (p < 0.05) among treatment groups.
In conclusion, the inclusion of up to 20% cattle rumen digesta supplemented with 0.025% Fullzymes in broiler diets had no adverse effects on carcass quality or blood parameters. Therefore, it is recommended as a viable alternative feed ingredient in broiler production.
