The high cost of conventional feedstuffs has necessitated the investigation into unconventional readily available feed alternatives such as Goat Rumen Digesta (GRD). A total of two hundred day old Anak broiler chicks were allocated to five (5) treatments groups (0, 25, 50, 75 and 100% GRC) levels and each treatment were replicated four times. The study was conducted to determine the effect of using different levels of GRD in Broiler Chicks diet on the performance, carcass characteristics, blood chemistry and cost effectiveness. The birds were fed diets containing 23% Crude Protein (CP) and 2900 Kcal/KgME at the starter phase and 20% crude protein and 3000 Kcal/kgME for the finisher phase. The results showed that feed intake, daily weight gain and feed conversion ratio were not significantly different from the control diets at both starter and finisher phases. Carcass analysis showed significant (P<0.05) effect of levels of GRD on gizzard. The values ranged from 1.762 to 2.07% on diets 1 and 2 and intestine length values ranged from 163.12 to 212.12cm across the treatments. The result of the blood chemistry analysis showed no significant treatment effect on all the parameters measured, which indicates that GRD does not contain toxic material. Similarly, the feed cost/kg weight gains were cheaper on the GRD diets than on the control diet. The result of this research indicated that GRD can replace wheat offal up to 50% with significant reduction in feed cost.
Key words: Goat Rumen contents, performance, carcass characteristics, blood chemistry, broiler, cost effectiveness.
