Effect of Adding Different Concentrations of the Hot and Alcoholic Aqueous Extract of the Seeds of the Kalgan Plant (Silybum marianum) to Drinking Water on the Productive Performance of Broiler Chicks ROSS 308

Abstract

Abstract This study is to evaluate the effectiveness of adding different concentrations of the hot and alcoholic aqueous extract of seeds of the local Kalgan plant (Silybum marianum) to water drinking on the performance productive of broilers and find the best ratios that achieve the highest results positive in productivity, It was used 315 of broiler chicks Ross 308 and It was randomly distributed to 21 (KN) with 7 trial transactions for each(3)bis transaction. The experiment treatments were as: T1(control) :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% and 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% and 7.5% respectively. The results showed a significant (p≤0.05) superiority for T6 and T7 coefficients in the average weight live body and the gain weight total compared T1 (control), the consumption total feed, the experimental coefficients (T6, T7, T4 and T3) achieved significant compared superiority T1 (control), recorded T7 the best cumulative food conversion with significant (p≤0.05) difference compared to treatments other. As for the carcass qualities, the treatment T7 achieved the best weight live body, and weight carcass and the net percentage, for the destruction, it was noted there were no significant differences between the experiment coefficients all. So the extract alcoholic of the seeds of the Kalgan plant at a concentration of 7.5% showed the best results In weight live body, the gain weight and consumption feed rate.
