Survey of different levels of Ajwain (Trachyspermum ammi) seed powder on performance and some blood parameters in japanese quails

This study was conducted to evaluate the effect of different levels of Ajwain (Trachyspermumammi) seed powder on performance, carcass characteristics and blood parameters of Japaneses quails. A total of 288 day old as-hatched Birds through 24 pens (6 treatments and 4 replicates) were used. Experimental diets included control diet (corn-soy), control antibiotic (positive control) and different levels Ajwain seed powder (containing 0.5, 1, 1.5 and 2 percent of diet) respectively. Results indicated that treatment containing of 1% ajwain seed powder significantly increased body weight in 14 and 28 days of age, and body weight gain in 7-14 and 7-28 days of age periods (P0.05) different between treatments in feed intake, feed conversion ratio and carcass characteristics, However relative weight of bursa of fabricius significantly increased by Ajwain treatments(P0.05). It could be concluded from the results present study that usage of Ajwain seed powder in diet increased of relative weight of bursa of fabricius, and at level of 1%, improved body weight and serum lipid profile of japaneses quails.
