Dietary Supplementation of Phoenix dactylifera Seeds Enhances Performance, Immune Response, and Antioxidant Status in Broilers

الملخص EN

The date palm (Phoenix dactylifera) seeds were utilized in some traditional medical remedies and have been investigated for their possible health benefits.

This proposed study wanted to assess the effect of date palm seeds (DPS) dietary supplementation in comparison to mannan-oligosaccharides (Bio-Mos®) and β-glucan over antioxidant and immunity events that have effect on growth and carcass performances of broilers.

An aggregate of 180, one-day-old, chicks were raised in the wire-floored cages and allotted into control, Bio-Mos (0.1% Bio-Mos), β-glucan (0.1% β-glucan), DPS2 (2% date crushed seeds), DPS4 (4% date crushed seeds), and DPS6 (6% date crushed seeds) groups.

Broilers in DPS2 and DPS4 groups showed significant variations (P<0.05) in relative growth rate (RGR), feed conversion ratio (FCR), and efficiency of energy utilization in comparison to control group.

Moreover, all DPS fed groups showed significant increases (P<0.05) in serum reduced glutathione (GSH) values.

Meanwhile, both serum interferon-gamma (IFN-γ) and interleukin-2 (IL-2) levels were significantly increased (P<0.05) in DPS2.

Consequently, obtained data revealed a substantial enhancement of performance, immunity, and antioxidant status by DPS supplementation in broiler that might be related to the antioxidant and immune-stimulant constituents of P.
