The present study was conducted at the experimental unit of the Department of Animal Production, Faculty of Agriculture, Omar Al - Mukhtar University, El - Bieda, Libya during the period of 28 days.
The main objective of the study was to investigate the effects of different levels (0, 5 and 10 %) of equal portions of discarded dates and olive mill wastes mixture on some blood parameters (lipid profile and some blood biochemical characteristics) in commercial broiler. Ninety birds of (Cobb 500) strain aged of two weeks were randomly allocated to three treatments each containing three replicates of 10 birds each.
The control group (0 %) received only the commercial diet, whereas the treated groups received the commercial diet including 5% or 10% of discarded dates and olive mill wastes. Protein% was adjusted in treated groups with soybean meal (44%).
The study lasted until the birds reached forty days of age, and blood samples were collected.
The results obtained showed a significant increase (p< 0.05) in the triglycerides levels in the blood (mg/dl), whereas the 10% treatment recorded the highest value compared to the control treatment, and the 5% treatment (50.0 vs. 38.7 and 34.3), while cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) were tended to decreased, insignificantly (p > 0.05), compared to control diet.
The obtained results also showed a significant increase (p< 0.05) in the rate of uric acid in the blood (mg/dl), as the treatment of 5% recorded the highest value compared to the control treatment (10.47 vs 7.23).
On the other hand, the results concluded that there was a significant decrease (p< 0.05) in the mean of total protein and globulin, as decreased in the 10% treatment compared to the control treatment (3.97 vs 4.83) and (2.63 vs. 3.47), respectively. Glucose was decreased insignificantly as the wastes in diets increased.
