BOTELLO LEON, A. et al. Growth performance, carcass traits and economic response of broiler fed of palm kernel meal (Elaeis guineensis). Cuban J. Agric. Sci. [online]. 2020, vol.54, n.4, pp.569-580.  Epub 01-Dez-2020. ISSN 0864-0408.

The objective of the study was to determine the growth performance, carcass traits and economic response of broiler chickens fed of palm kernel (Elaeis guineensis) meal (PKM). A total of 120 one-day-old Cobb-500® male chicks were evaluated for 47 days and were assigned to four dietary treatments using a completely randomized design. Dietary treatments consisted of a control diet (T0) and three other diets containing 100 (T1), 200 (T2) and 300 (T3) g/kg of PKM. Compared to birds fed T0, birds fed T1 had no effect (P > 0.05) on the measured parameters of growth performance and carcass traits, birds fed T2 and T3 had higher feed intake (139.75-145.79 g/bird/day) (P < 0.05) and feed conversion (2.08-2.41) and birds fed T3 had lower (P < 0.05) final weight. In addition, T2 and T3 birds had lower (P < 0.05) carcass weight, breast weight and total viscera weight, whereas T3 birds had lower (P < 0.05) leg weight. Increasing levels of PKM in diets decreased (p < 0.05) the cost of consumed feed, the feed cost to produce one kg of live weight, carcass, breast, and leg with economic utilities. These findings indicate that palm kernel can be used up to 100 g/kg in male broiler diets as partial replacement for corn and soybean meal, without affecting performance and carcass traits, however, inclusion of 300 g/kg of PKM had the best cost-benefit analysis.
