ABSTRACT
Silymarin is a flavonolignan extracted from the milk thistle plant (Silybum marianum). Silymarin has various pharmacological properties, including hepatoprotective, antioxidant, anti-inflammatory, anticancer, and cardioprotective effects. The study aims to determine the influence of several levels of silymarin on the productive and biochemical parameters in local lambs. A total of 30 lambs are classified into three groups. G1 (ten lambs) received Silymarin (420 mg/kg) orally, G2 (ten lambs) received Silymarin (210 mg/kg) orally, while G3 (ten lambs) received distal water (control group). Several parameters are used in the current study to evaluate silymarin, such as Hb, PCV, Triglyceride, cholesterol, total body weight and feed conversion efficiency. The mentioned parameters are examined biweekly for eight consecutive weeks. The findings reveal an increase in Hb, PCV, body weight and total protein levels in G1 compared to G3 at (p <0.05), as well as Hb, PCV, body weight, and total protein increased with increasing dose (P <0.05). On the contrary, the value of feed conversion efficiency, triglycerides and cholesterol were decreased in G1 and G2 compared to G3 (P <0.05). Furthermore, feed conversion efficiency, triglyceride, and cholesterol decreased with increased dose used (P <0.05). Ultimately, we can conclude that Silymarin can improve hematological and biochemical parameters and decrease feed conversion efficiency, as well as triglycerides and cholesterol in local lambs.
