This study investigated the effect of dietary Ethiopian pepper (Xylopia aethiopica) and clove (Syzygium aromaticum) supplementation on the growth performance, serum parameters, and haematological indices of broiler chickens. A total of 360 unsexed Ross broilers were used for the study. Four experimental diets were formulated for the starter (0-28 days) and finisher phases (29-56 days). Diet 1 was the control, without phytogenic supplementation, Diet 2 was supplemented with 1% Ethiopian pepper (EP), Diet 3 was supplemented with 1% clove (CL), and Diet 4 was supplemented with 1% mixture of Ethiopian pepper and clove (EPCL) in equal quantities (0.5% each) (EPCL). Each treatment was replicated 6 times, with 15 birds per replicate. Growth response was measured weekly for the starter and finisher phases, and blood was collected for serum and haematological parameters after 4 and 8 weeks. Data were subjected to one-way analysis of variance using SAS 2000, and significant means were separated using Tukey's test in same software. At day 28, dietary supplementation with EPCL increased (P < 0.05) live weight (LW) (660.34 g) and weight gain (WG) (599.66 g) and improved the feed conversion ratio (FCR) (0.98). Total protein (TP) (48.00 g/L) and albumin (28.30 g/L) were higher (P<0.05) for broilers fed a diet supplemented with EPCL compared to the other treatments. Packed cell volume (PCV) (30.00%) was higher (P < 0.05) in broilers fed a diet with EPCL. Supplementation with CL and EPCL increased (P < 0.05) the red blood cell (RBC) count in broilers. Broilers fed a diet supplemented with EP had lower (P < 0.05) mean corpuscular volume (MCV) (97.77 fl), while those fed the control diet had higher (P < 0.05) mean corpuscular haemoglobin (MCH) (39.45 pg). Broilers fed the control diet had the highest (P < 0.05) mean corpuscular haemoglobin concentration (MCHC) (37.90%), while those fed diets supplemented with CL (33.29%) and EPCL (34.00%) had the lowest (P < 0.05) MCHC. At day 56, LW and WG were also increased (P < 0.05) by supplementation. Reduced (P < 0.05) cholesterol was observed for broilers fed a diet supplemented with EPCL. Haemoglobin (Hb) and RBC were higher (P < 0.05) in broilers fed a diet supplemented with EPCL. Supplementation with EP, CL and EPCL resulted in higher (P < 0.05) MCV and MCH. It was concluded that EPCL can be used to supplement the diet of broilers for increased performance and improved blood parameters. [ABSTRACT FROM AUTHOR] |
