Abstract :
The aim of the study is to assess the effects of dietary Inclusion of different Levels of Hibiscus seeds on performance, gut health and fatty acid profile of broilers. The Roselle (Hibiscus Sabdariffa) seeds were incorporated in broiler rations at levels of (k0%, k3%, k5% a n d k7%) the study was run in 6 weeks period using four experimental diets. The experimental diets were formulated iso-energetic and iso-nitrogenous to meet or exceed the requirements of broilers according to (NRC, 1994). The experiment was carried out in a complete randomized design (CRD). A total of 120 one day-old (Ross308) broilers were allocated to the four treatments (K0 (control), K3, k5 and k7) and each treatment was further divided randomly into three replicates with ten birds each Feed consumption (FC), weight gain(WG) and feed conversion ratio (FCR) were recorded. At the end of the experiment, two birds from each experimental unit were selected according to their closed to average weight and slaughtered. Carcass weight, weights of some internal organs and cuts were measured. Total bacterial load and some pathogenic bacteria were investigated in Gizzards and cecum of birds to assess the antimicrobial effects of Roselle seeds inclusion in broilers rations on bird’s gut heath. All data was statistically analyzed using ANOVA. Result showed that there were no significant differences (P>0.05) in broilers performance but numerically decrease in feed intake, weight gain and increase feed conversion with the increase of Roselle seeds in the diets and there was no effects on the mortality rate of birds. The weights of internal organs results showed that there were no significant differences among treatments except kidney weight. Bacterial account was highly significant differ (p≤0.05) and without effect on total bacterial load due to the inclusion of Roselle seeds in broiler rations. While there no presence significant differences on E. Coil and Staphylococcus aureus presence in gizzard and cecum samples among treatments. Dietary Inclusion of different Levels of Hibiscus Seeds had no deleterious effect on broiler performance or total bacterial, there for it recommended to include Roselle seeds 3% and do not up to 7% in broiler diets.
