Impact of guar meal inclusion on serum biochemistry and nutrient Metabolizability in Japanese quails

An experiment was conducted to study the impact of inclusion of different levels of the guar meal in Japanese quails. 150-day-old chicks were randomly allotted to five dietary treatments: T1 (0% GM), T2 (2% GM), T3 (4% GM), T4 (6% GM) and T5 (8% GM), with three replicates per treatment (10 birds each). All liver and kidney function tests were performed. The glucose and serum total cholesterol levels were numerically decreased as the level of guar meal increased. There was a numerical decrease in serum triglyceride levels in the treatment groups compared to the control, the differences were not statistically significant (p>0.05). An increase in HDL levels was observed from T1 to T5 groups as the dietary level of GM increased from 0 to 8.0 percent. Serum glucose levels decreased numerically from 171.15 mg/dL (T₁) to 140.59 mg/dL (T₅), suggesting potential metabolic benefits. Similarly, other parameters, including AST, ALT, BUN, creatinine, calcium and phosphorus, were unaffected (p>0.05) by GM inclusion. Digestibility coefficients for dry matter (DM) and organic matter (OM) were significantly higher (p<0.05) in the 6% GM (T₄) group, while crude protein (CP), ether extract (EE), crude fiber (CF) and nitrogen-free extract (NFE) digestibilities did not differ significantly (p>0.05) among groups. The study concluded that Inclusion of guar meal up to 8% did not show any effect on the metabolizability and serum biochemical profile of the Japanese quails.
