Objective: This experiment studied effect of Gum Arabic as a supplementary diet and its effect on lipid profile (serum, egg yolk and meat) and performance of Laying Hen. Methodology and results: One hundred and fifty commercial laying hens (29 weeks age/ white lohmann) were used.
The 150 laying hens are divided into five groups randomly G1, G2, G3, G4 and G5, where each group contained 30 laying hens kept in separated battery house. G1(Control) was fed basal layers diet while G2, G3, G4 and G5 were fed basal diet supplemented with Gum Arabic concentration at 1, 3, 5 and 7% respectively.
The study revealed that in serum, there was a significant decrease in cholesterol, triglyceride, but no significant difference in High Density protein (HDP) - cholesterol at P≤ 0.05, in egg yolk. There was a significant decrease in cholesterol for G5 compared with G1, also there was a significant decrease Triglyceride in G4 and G5 compared with G1 indicated that there was a decrease in phospholipids in G5 compared with G1. Lipid profile of meat for treated groups (G2, G3, G4 and G5) showed no significant difference at P≤ 0.05 compared with non- treated group (G1). The performance (body weight, egg weight and daily egg production) of laying hens showed significant increase at P≤ 0.05, but there was an increase in body and egg weight. Finally, there was no significant difference in daily egg production at P≤ 0.05. The addition of Gum Arabic as supplement of laying hens diet indicated there was no significant difference in serum cholesterol and daily egg production. Whereas, it is showed significant decrease in triglyceride, total lipid and phospholipids, but indicated significant increase in egg and body weight. Application of Gum Arabic as supplement in the diet of poultry production should be done because Gum Arabic is rich in highly soluble fiber.
