Utilization of Cassava Roots as a Source of Energy in Broiler Chicken feed and its effects on Blood chemistry and Digestibility

The objective of this study was to evaluate the impact of using different levels of cassava roots as a source of energy in diets of broiler chicken and its effects on blood chemistry and digestibility. The experiment was conducted in Kenana Poultry Farm for Research and Development. Complete Randomized Design was used. A total of 160, unsexed one- day old (Ross308) broiler chicks were randomly divided into four dietary treatments. The treatments contain 0%, 15%, 25% and 40 % cassava roots of the total rations. Each treatment was sub-divided into four replicates: with each having 10 experimental birds. All diets were formulated according to (NRC) to meet the nutrient requirements of the broiler chickens. The results revealed that all parameters value of blood chemistry (Calcium, Phosphorus, Albumin, Triglyceride, Cholesterol and Total protein) was not affected significantly (P≥0.05) by the usage cassava roots in diets fed to broiler chickens throughout the experimental period, except for Glucose. The hematological parameters were not affected by dietary treatments of cassava roots. The parameters of digestibility in obtained results were significantly affected by the using of cassava roots in diets fed to broiler chickens in fat and crude protein digestibility which was higher (p≤0.05) in group received 25% cassava roots. However, there was no significant (P≥0.05) difference in feed digestibility.
