Olive cake is one of the most available by-products of local farming in Palestine, estimated at 36,000 tons/year (Ministry of Agriculture 1999). This amount is of great importance as a potential feed component when used at certain levels in livestock rations. The feeding costs in Palestine make up more than 70% of the total production costs in any livestock operation. Therefore, it is highly recommended to incorporate raw materials and farm by-products in ration formulation as possible (Shqueir and Qawasmi, 1994). The objective of this research is to investigate the effect of feeding different levels of olive pulp as part of finishing rations on the digestibility parameters of broiler chicks. A total of 18 birds at 22 days of age were used in the digestion trial. Birds were divided into three groups, and each bird in the group was a replicate. Birds were kept in their cages for 3 days of adaptation to the new environment and rations. This period was followed by a 6-day total collection period. . Samples from each ration were collected and stored for later analysis. During the collection period, feed intake, fecal output and feed refused were weighed and sampled for later analysis. The analysis of olive pulp samples showed a content of 10.6% crude protein, 12% crude fat, 26% crude fiber, 24% acid detergent liginin and 33% acid detergent fiber. These results agree with those reported by Rabayaa (2000), that the crude fat content was lower.
