This study investigated the impact of nutmeg flesh extract on intestinal morphology,
bacterial population, blood profile and antioxidant status of broiler chickens stocked at high
density pens. After 15 days of rearing, 370 Lohmann broiler chicks (unsexed) were assigned to
five treatment groups based on a completely randomized design, including T0 (chicks were raised
at a density of 10 birds m-2 and received no nutmeg flesh extract), T1 (chicks were raised at a
density of 16 birds m-2 and received no nutmeg flesh extract), T2 (chicks were raised at a density
of 16 birds m-2 and received 0.5 mL kg-1 nutmeg flesh extract), T3 (chicks were raised at a density
of 16 birds m-2 and received 1.0 mL kg-1 nutmeg flesh extract), and T4 (chicks were raised at a
density of 16 birds m-2 and received 1.5 mL kg-1 nutmeg flesh extract). Sampling was conducted
on day 35 of age. The results showed that the administration of nutmeg flesh extract (regardless
of its levels) to broilers diets at high density (16 birds m-2
) significantly (p ≤ 0.05) increased the
performance, villi height in the duodenum, jejunum and ileum, decreased pH in the ileum and
cecum, increased lactic acid bacteria and decreased coliform bacteria in the ileum and cecum,
decreased malondialdehyde (MDA) and increased superoxide dismutase (SOD) and had no
significant effect (p > 0.05) on the blood profile of broiler chickens. The findings demonstrated
that nutmeg flesh extract improved performance, intestinal bacterial population and morphology
and antioxidative status of broilers raised under high density condition.
