This study aimed to study the effects of fermentted toona sinensis leaf on laying performance,egg quality and serum biochemical index of laying hens.A total of 320 No.8 Jingfen laying hens(300-day-old)were selected and randomly divid-ed into four groups with eight replicates in each group and ten hens in each replicate.The control group was fed the basal diet,and the experimental groups were supplemented respectively with 1%fermentted toona sinensis leaf,2%fermentted toona sinen-sis leaf,and 3%fermentted toona sinensis leaf.The pre-trial period was seven days,and the formal trial period was 60 days.The results showed that:in terms of the production performance,compared with that of the control group,the egg production rate of the trial group was increased,and the average egg weight was significantly increased(P<0.05);In terms of the egg quality,al-bumen height was increased,and on day 60 of experiment,the egg yolk color was significantly increased(P<0.05);On the se-rum biochemical indicators,on day 60 of experiment,the plasma contents of glucose(GLU)was significantly decreased(P<0.05),and the contents of plasma of albumin(ALB),high density lipoprotein(HDL)were significantly increased(P<0.05),the addition of 3%fermentted toona sinensis leaf could significantly reduce the blood urea nitrogen(BUN)(P<0.05).The fermentted toona sinensis leaf could improve the digestion and absorption of protein,and improve the level of lipid metabolism.
