Effect of A Partial Substitution of Soybean Meal with Guar Meal on Blood Biochemistry Characteristics in Broiler Chickens

Poultry diets are enhanced with supplementary products aimed at optimizing the feed efficiency by utilizing guar, which is obtained through the mechanical extraction of galactomannan-containing saponins. This study was carried out to estimate the main effects of feeding 10% guar meal (GM) combined with or without antibiotic and anticoccidial supplementation on the blood biochemistry of broilers. The experiment used 150 birds at one-day old for 42 days. The birds were divided into five groups, each including 30 birds with three replicates (10 birds of each). The treatment diets were T1: control, T2: guar meal 10%, T3: salinomycin 500 g.ton −1 , T4: salinomycin 500 g.ton −1 and gaur meal 10%, and T5: salinomycin 500 g.ton −1 , mycofix 2 kg.ton −1 , and gaur meal 10%. The results showed that serum triglycerides, LDL, and VLDL levels were significantly lower in T2, while HDL levels increased in the same treatment. Inclusion of salinomycin and maycofix in the diet significantly elevated serum triglycerides, LDL, VLDL, TG, glucose, and cholesterol concentrations in the serum of broilers. The substitution of 10% GM with soybean meal in the diet of broilers has a positive effect on studied biochemical parameters.
