Effects of Allicinon on Production Capacity Caecum Microorganism and Serum Biochemical Index in Laying Hens

240 laying hens of 62-week-old were randomly divided into four groups,each group has four replicates,each replicate has 15 laying hens.Laying hens were fed a basal diet or allicin at 50,100,150mg/kg of basal diet respectively.The testing period was five weeks.The effect of allicin on performance and caecum microorganism and serum biochemical index in laying hens was determined.The results were as follows:The diets supplemented with 50 mg/kg and 100 mg/kg allicin significantly increased feed efficiency during 62-67 week(P0.05).The diets supplemented with 50,100 and 150 mg/kg allicin has restrained the E.coli in caecum contents(P0.05),and significantly increased the level of ALB in serum(P(0.05).)
