Effect of Adding Local and Egyptian Palm Pollen (Phoenix dactylifera L.) to Diet on Some Blood Biochemical Barometers and Intestinal Flora of Broiler Roos 308

Abstract

The experiment was conducted to study the effect of adding local and Egyptian palm pollen to broiler feed on some blood biochemistry parameters and intestinal flora by using 400 broiler chicks Ross308 one-day age and divided into 8 treatments and 5 replicates. Each treatment includes 50 birds, 10 birds per replicate. Palm pollen was added to the diet from the first day till the end of the experiment (42 days). The first treatment was a control without any addition. The second and third treatments included the addition of 1 and 2 kg/ton from local palm pollen, while the fourth and fifth treatments added 1 and 2 kg/ton from Egyptian palm pollen As for the sixth treatment, the addition of 1 kg of local palm pollen/ton +1 kg of Egyptian palm pollen/ton as well as the seventh treatment 1 kg of local palm pollen/ton + 2 kg of Egyptian palm pollen/ton and the eighth was the addition of 2 kg of local palm pollen / ton+1 kg Egyptian palm pollen/ton. The experiment results showed significant differences (p<0.05) in the concentration of protein, albumin, globulin, glucose, Cholesterol and LDL when adding palm pollen compared to the control treatment. There was a significant increase in HDL in the treatments added with palm pollen and the activity of liver enzymes ALT and AST. There was an improvement in the antioxidant status, as there was a decrease in the levels of malondialdehyde and an increase in the levels of GSH glutathione in the palm pollen supplementation treatments compared to the control treatment. Also, a significant decrease was recorded in additional treatments in the numbers of E. coli bacteria and a significant increase in additional treatments in the numbers of Lactobacilli compared with the control treatment.
