Effect of Monkey Flower (Scrophularia Striata) on Performance, some Blood Parameters and Histology of Intestinal Jejunum in Growing Japanese Quail

To compare the effect of different levels of monkey flower (MF) (Scrophularia Striata) powder on performance, blood parameter and jejunum histology in growing Japanese quail, the experiment was carried out in a completely randomized design with 400 3d quails was assigned with five treatment and four  replicates  with 20 quail in each replicate. Experimental groups included: 1) basal diet. 2) basal diet with 0.04 g/kg flavophospholipol 3) basal diet with %1 MF powder, 4) basal diet with %2  MF powder, 5) basal diet with %3 MF powder. The use of MF powder had no any significant effect on avergage daily gain and feed conversion ratio, but the feed intake were increased by experimental treatments. Use of different levels of MF powder had a significant effect on jejunum crypt depth. Also, different levels of MF did not significantly affect sexual hormones, but this levels had significant effect on some intestinal histology and feeed intake in both sexes. Although MF powder especially 2 % level, improved live weight and feed intake in mal birds at different periods, but it can could not improved performance in female birds.
