Abstract:The purpose of this experiment was to evaluate the effects of different raising systems on performance,egg quality and serum biochemical indices of laying hens.A total of 54022~week-old Hyline Brown laying hens with similar laying performance were randomly divided into 3 groups with 5 replicates per group and 36 hens per replicate.Laying hens in the cage rearing group were reared on a three-layer ladder(0.6 m2/hen),laying hens in the net rearing group were reared on a metal mesh(1.5 m2/hen),and laying hens in the pad rearing group were reared on a cement floor with 20 cm rice husk(1.8 m2/hen).The trial was conducted for 28 weeks,including 2 weeks of adaptation period.Results:Compared with cage rearing group,the average daily feed intake of laying hens in net rearing group and pad rearing group at 24~36 w and 24~29 w were significantly increased by 5.71%,6.22%and 4.81%,4.48%(P<0.05),respectively.In addition,feed conversion ratio of laying hens in pad rearing group at 24~36 W and 24~49 W was significantly increased by 7.31%and 4.09%compared with cage rearing group,respectively(P<0.05).At 36 w,the eggshell strength and dirty egg rate of eggs in the flat feeding group were the highest and the lowest(P<0.05).At 49 w,the egg shell thickness of the caged group was the lowest(P<0.05),and the dirty egg rate was the highest(P<0.05).The concentrations of serum glucose,triglyceride,total protein and cholesterol of laying hens in cage rearing group were the highest(P<0.05),but the concentrations of high-density lipoprotein were the lowest(P<0.05).In conclusion:The feed intake of laying hens can be improved by net flat rearing and pad flat rearing,but the feed efficiency of laying hens reared in cage is the best.In addition,the eggshell strength and thickness of the eggs were improved and the rate of egg breaking was reduced.
