Evaluation of the Effectiveness of Adding Different Concentrations of Hot and Alcoholic Aqueous Extract of the Seeds of the Kalgan Plant (Silybum marianum) to Drinking Water on Some Serum Biochemical Qualities in Broiler chicks ROSS 308

The current study aims to evaluate the effectiveness of adding different concentrations of hot aqueous and alcoholic extract of the seeds of the local Kalgan plant (Silybum marianum) to drinking water on some biochemical qualities of broiler and to find the best ratios that achieve the highest positive results in their physiology. Where 315 unnaturalized Ross broiler chicks were used in the experiment, randomly distributed to 21 (KN) by 7 treatments per treatment of 45 chicks and each treatment included 3 replicates per 15 birds. The experiment treatments were as : T1: free of any addition, and T2, T3, T4 : addition of 2 ml of hot water extract for the seeds of the Kalgan plant / liter of drinking water at a concentration of 2.5%, 5%, 7.5% respectively, and T5, T6, T7 : addition of 2 ml of alcoholic extract of the seeds of the Kalgan plant / liter of water drinking at a concentration of 2.5%, 5%, 7.5% respectively. The results for the total protein concentration showed no significant differences between all the experimental coefficients. While a significant (P≤0.05) superiority was obtained for T7 in the concentration albumin compared to the experimental coefficients, For the concentration of globulin, was recorded T6 and T7 a significant superiority compared to T1 (control) a significant decrease (P≤0.05) was observed in the concentration of the enzyme (Alanine Aminotransferase) ALT for the T6 and T7 coefficients compared to the T1 (control), For the concentration of AST (Aspartate Aminotransferase), no significant differences were observed between all the coefficients of the experiment, and the coefficients T4, T5, T6 and T7 a significant (p≤0.05) in the level of cholesterol concentration. For the concentration of triglyceride, the coefficients T4, T6, T7 recorded a significant (p≤0.05) compared to the T1 (control), No significant differences were observed between all the experimental coefficients for HDL (High Density Lipoprotein). While the T1 (control) recorded increase in LDL (low-density lipoproteins) concentration and a significant decrease (p≤0.05) in the concentration of VLDL (very low-density lipoproteins) in bird blood serum compared to T1 (Control) treatment. So the alcoholic concentration of Kalgan seeds of 7.5% had a positive effect on the physiological or chemical characteristics of broilers 308ROSS.
