Effect of dietary mallow (Malva parviflora L.) leaves powder on physiological traits and productive performance of Japanese quail


This study was undertaken at the Poultry Farm/ Department of Animal Production/ College of Agriculture/ University of Baghdad, during March and April/ 2014. The aim of this experiment was to investigate the effect of dietary different levels of dried mallow leaves powder on productive and physiological performance. A total of 120 Japanese quail, 3weeks old, were brought from Poultry Research Center/ Ministry of Agriculture. Quails were fed ad libitum with standard basal diet contains 2903 kcal/kg diet ME and 20% crude protein. The treatments were as follows: T0 control group without any addition, T2, T3, T4: dietary supplemented with 0.25, 0.50 and 1% mallow dried leaves powder respectively. Chemical analysis of plant leaves powder revealed that mallow contains 94.2% dry matter, 30.5% crude protein, 21.9% ether extract, 7.8% crude fiber. Specific chemical detection showed the existence of glycosides, alkaloid, saponine and flavonoids. Productive traits studied included: body weight, feed consumption and egg qualities while, physiological traits included: PCV, Hb and the levels of glucose, total protein, creatinin, serum lipid profile, the activity of ALT, AST, and the relative weight of heart and liver. Results showed no significant differences in body weight and relative weight of heart and liver between treatments, whereas, there were significant (P≤0.05) reduction in total feed consumption in T3 compared with control group. Also, T3 resulted in significant (P≤0.05) increasing in egg albumin and yolk height at 8 weeks of age in comparison with T2. Serum total protein was significantly( P≤0.05) higher in T3 in comparison with T2, farther more, T3 significantly increased (P≤0.05) serum cholesterol in comparison with T1 and T2 and low density and very low density lipoproteins in comparison with control and all other treatments. Results of recent study concluded that adding 1% mallow dried leaves to Japanese quail diet from 5-8 weeks old resulted in reducing total feed consumption, increasing in: egg albumin, yolk height, yolk index and the levels of serum total protein, cholesterol, low and very low density lipoproteins in comparison with the less adding percentage 0.25% and 0.5% which showed a positive effect in reducing the hurtful blood lipid in comparison with unsupplemented group
