| Abstract: | The purpose of this study was to investigate the effects of Chinese herbal compound additives on production performance,egg quality and eggshell ultrastructure of elderly laying hens.Nine hundred 440-day-age Hy-line Brown chickens were divided into the control group and experimental group with 5 replicates in each group and 90 chickens in each replicate.The control group was fed with basic diet,and the experimental group was fed with basic diet added with 0.2% Chinese herbal compound additives.The pre feeding period was 7 days and the experimental period was 56 days.The results showed that compared with the control group,the culling rate and broken(soft)egg rate in the experimental group decreased by 32.50% and 15.11% respectively(P<0.05),the feed egg ratio decreased by 9.38%(P<0.01),and the eggshell strength,protein height and Haugh unit increased by 12.38%,16.38% and 9.84% respectively(P<0.05),the relative quality of egg yolk,egg shape index and eggshell thickness all increased;In the experimental group,the cuticle on the eggshell surface was smooth,the cracks were reduced and the width was narrow,the section of the vertical crystal layer was neat,the lattice edges and corners were clear,the arrangement was dense,the number of holes was large and evenly distributed,and the size was the same.The palisade layer was dense,the milk cone layer was closely connected,the mastoid process was wide and closely connected with the eggshell membrane.The results indicated that the additive could significantly improve the production performance and egg quality,eggshell ultrastructure of elderly laying hens. |
