Abstract

The objective of this investigation was to determine the effect of graded levels of dried sweet orange (Citrus sinensis) peel powder supplementation on growth performance and some physiological and biochemical parameters of broiler chicks. A completely randomized design was used, with 180 one-day-old Ross 308 chicks randomly assigned to four dietary treatments (10 birds/replicate, three replications/treatment). The basal diet was fed to the control group (D1) while the groups D2, D3 and D4 were supplemented with 0.5, 1.0 and 1.5% orange peel powder, respectively. The feeding trial was 42 days. At all times during this period, the following performance measurements were taken and recorded, namely: live body weight, weight gain, feed intake and feed conversion ratio. The blood samples were collected for the estimation of serum total cholesterol, triglycerides, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) at the end of the trial. Data were subjected to one-way analysis of variance and linear and quadratic trend analysis was carried out for the increase in inclusion levels. Statistically significant difference was set at P<0.05. The hypothesis in the study was that the bioactive compounds in orange peel such as flavonoids, polyphenols, pectin, and essential oils, may help to enhance nutrient utilization, control lipid metabolism, and preserve the physiological status of liver in broilers.
