Study On The Effect Of Plant Essential Oil Meal On Growth Performance,apparent Digestibility And Digestive Enzyme Activities Of Broilers

Three experiments were conducted to study the effect of Plant Essential Oil meal on Growth Performance,Apparent Digestibility and Digestive Enzyme Activities of broilers.ExperimentⅠ: To study the effect of Plant Essential Oil meal on production performance, 600 broilers (initial BW= 44.08±0.79g)were divided into six treatments,based meal,antibiotic meal,Plant Essential Oil meal(100,200,250,150mg/kg),6 replicates in each treatment, 20 carps for each replicate. The results showed that: (1) the Average individual daily weight gain (P<0.01) were remarkable increased for broilers fed 100mg/kg Plant Essential Oil meal;(2) broilers fed 100mg/kg and 200mg/kg Plant Essential Oil meal were significantly increased in Average individual daily feed intake significantly than control group(P<0.05);(3) Plant Essential Oil meal on feed-weight ratio were decreased than control group,but not significantly.ExperimentⅡ:When feeding trial(ExperimentⅠ), 1 carps each replicate were fed alone to collect faeces to study the effect of Plant Essential Oil meal on apparent digestibility. The results showed that: (1) 100mg/kg,200 mg/kg,250mg/kg Plant Essential Oil meal on crude proteinum digestibility were significantly higher than control group,(2) Plant Essential Oil meal on Ca and P digestibility were increased than control group,but not significantly.ExperimentⅢ: When feeding trial ended(ExperimentⅠ), 2 carps from each replicate were slaughtered to study the effect of Plant Essential Oil meal on digestive enzymes activities. The results showed that: amylase and protease in broilers fed 100mg/kg,200 mg/kg,150 mg/kg Plant Essential Oil meal increased significantly than that in control group(P<0.05).
