Effect of adding Salvia officinalis leaves powder to the ration on productivity characteristics of broiler type Ross 308

This study was conducted at the Poultry Farm -Dept. of Animal Science, College of Agriculture, AL-Qasim Green University to investigate the effect of adding Salvia officinalis leaves powder to the ration on productivity characteristics of broiler type Ross 308. 90 unsexed broiler chicks one day-old were used and randomly assigned to three treatments with 3 replicates per treatment and 10 chicks per replicate. The treatments were as follows: control group without adding Salvia officinalis leaves powder to the diet, adding Salvia officinalis leaves powder by 1% (first treatment), and adding Salvia officinalis leaves powder by 2% (second treatment). The experiment included a study of the following characteristics: live body weight, weight gain, feed consumption, feed conversion ratio, and mortality rate. The results indicated that, the addition of Salvia officinalis leaves powder by 1% and 2% to broiler diet led to significant improvement in the live body weight ،weight gain, and significant decrease in the mortality rate. No significant differences were found between all treatments in the rest of productivity characteristics. This experiment concluded that adding Salvia officinalis leaves powder to the ration can lead to improve production performance of broilers.
