Abstract :

This research investigated the effect of different levels of green coffee powder (GCP) on growth perform-ance, immune response, biochemical blood indices, and intestinal morphology in broiler chickens. A total of 300, one-day-old male Ross broilers were used in a completely randomized design with six treatments, five replicates, and 10 chicks each. The dietary treatment included six levels of coffee powder (0.0, 0.3, 0.6, 0.9, 1.2, and 1.5%). Compared to the control, GCP, at 0.3% and 1.5% increased the body weight gain and feed intake in broilers (P<0.05). Compared to the control, a lower feed conversion ratio was observed in broilers fed with 1.5% GCP (P<0.05). Adding 0.9% of GCP to the broiler diet increased relative weight of the breast, thigh, and bursa fabricius, compared to the control. The GCP at all levels reduced the relative weight of abdominal fat compared to control (P<0.05). The coffee powder did not affect the immunoglobu-lin M index against sheep red blood cell (SRBC); however, the total antibody index against SRBC in-creased in chickens fed GCP compared to the control (P<0.05). Coffee powder decreased blood cholesterol, low-density lipoprotein (LDL), and triglyceride concentration and increased blood high-density lipopro-tein (HDL), albumin, glucose, and protein concentration compared to control (P<0.05). The villi height and crypt depth increased in broilers fed 1.2% GCP compared to control (P<0.05). It is concluded that using green coffee powder at the level of 0.3% in the broiler diet may improve growth performance and some biochemical indices; however, the levels of 1.2 and 1.5% GCP improved the intestinal morphology and immune response of broilers.
