Abstract

The growth performance, carcass characteristics and meat quality measurements were evaluated on broiler chicks fed different dietary levels of whole inedible dates (WID). WID used in this study were consisted of date fruits (∼850 g/kg) and date pits (∼150 g/kg). Three hundred unsexed Lohman broiler chicks were randomly and equally distributed into six groups. Each was formed of 50 chicks (five replicates, 10 chicks per replicate), and was assigned to a dietary treatment. Six dietary treatments of WID (0, 30, 60, 90, 120 and 150 g/kg feed) were included in the formation of isocaloric (metabolizable energy of ∼3060 kcal/kg feed) and isonitrogenous (CP of ∼192 g/kg feed) broiler rations. The treated rations were fed to the group chicks between 15 and 42 days of age (the experimental period). A straight-run design was considered. At 42 days of age, five males from each treatment were randomly chosen and slaughtered to determine carcass characteristics, internal organs and meat quality measurements. Digestibility of nutrients was measured at the end of the experimental period using five caged-individual males per treatment. The inclusion of broiler rations on WID for up to 150 g/kg feed, over the experimental period, did not significantly influence body weight gain (1452 to 1521 g/chick), feed intake (3268 to 3621 g/chick), feed conversion ratio (2.26 to 2.36 kg/kg) and dressed carcass (63.4% to 67.3%). In addition, levels of WID for up to 150 g/kg feed did not significantly influence the digestibility of nutrients and meat quality measurements. Such results suggest the possible inclusion of broiler rations on WID for up to 150 g/kg feed, during the period of 15 to 42 days of age without adverse effects on growth performance and meat quality.
