Abstract :
This experiment was conducted to evaluate the effects of different levels of Alhaji maurorum L. on egg production,egg traits and blood parameters of commercial laying hens. In this experiment 144 Hy- line )W36( laying henswere used from 65-76 weeks of age in 4 treatments, 3 replicates and 12 hens in each replicate in a completelyrandomized design. Experimental groups included: 1( control group, 2( group with 1.5, 3 and 4.5 percentage ofAlhaji maurorum L. Different levels of Alhaji maurorum L. had signifcant effects on performance, egg traitsand blood metabolites of laying hens )p<0.05(. The highest amounts of egg mass, the highest egg productionpercentage, the best feed conversion ratio, and the lowest price of feed intake for production per kilogram of eggwere resulted by using 3% of Alhaji maurorum L.. 3% of Alhaji maurorum L. signifcantly improved special eggweight, egg yolk color and eggshell surface/eggshell weight. The lowest percentage of heterophile, the highestpercentage of lymphocyte and the lowest ratio of heterophile/lymphocyte were resulted by using 3% of Alhajimaurorum L. Different levels of Alhaji maurorum L. did not have any signifcant effects on blood biochemicalparameters of laying hens )p>0.05(. The overall results indicated that in commercial laying hens using 3% ofAlhaji maurorum L. without having any adverse effects on blood parameters, improve the performance and eggtraits of laying hens and decreased the amount of feed price for production each kilogram of egg. Using Alhajimaurorum L. in laying hens diets is an effective way in weeds control of agriculture crops
