黄腐酸对海兰褐蛋鸡产蛋性能及蛋品质的影响
Effects of Fulvic Acid on Laying Performance and Egg Quality of Hyline Brown Layers
摘要
Abstract
To research the effects of fulvic acid (FA)on laying performance and egg quality,four hun-dred 120 -day -old Hyline brown layers were randomly divided into 4 groups with 100 layers each group.The layers were randomly fed diets with different FA adding levels (0.1%,0.2% and 0.4%)using the diet with no FA as control.The trial period lasted 210 days from 140 -day -old to 350 -day -old.The results indica-ted that compared with control group,the 0.1% FA adding group significantly improved the intensity of egg shell (P <0.05 ),significantly decreased the color grade of egg yolk (P <0.05)and had no significant effects on laying performance,height of egg white,Haugh unit and thickness of egg shell (P >0.05).The 0.2% FA adding group significantly decreased the laying performance,color grade of egg yolk,intensity and thickness of egg shell (P <0.05),and had no significant effects on height of egg white and Haugh unit of eggs (P <0.05).The 0.4% FA adding group significantly decreased the laying performance and all indices of egg quality (P <0.05).Thus,adding 0.1% or above FA in diet all had negative effects on laying per-formance and egg quality in varying degrees.关键词
