Abstract：Inresponse totheurgentneed forrefined managementandscientific feeding strategies inthecurrentlaying duck industry，avalidationstudywasconductedontherecentlypublished“NutrientRequirementsofLaying Ducks”（GB/T41189 2021）.Diets were formulated at 95 % ， 100% ，and 105% of the standard recommended nutrient levels to investigate the applicability of curentstandards throughcomprehensiveevaluationofproductionperformanceandegquality.Atotalof16halthy9-weekoldLongyan Shanmaducks with similarproductionperformance wererandomlyalocated intothreegroups，with sixreplicatesper groupandtwelveducksperreplicate.Theexperimental dietswereadministeredforan18-week trialperiod.Theresultsrevealed that：（1）Regardinglaingperformance，nosignificantdiferenceswereobservedinlayingrateandfed-togratioamonggroups （ P>0.05 ）.However，significant efects were detectedon feed intake，average egg weight，andegg breakage rate.The lowest feed intake was recorded in the 100% group，while the highest average egg weight and lowest egg breakage rate were observed in the 105% group（ P<0.05 ）.（2）In egg composition analysis，significant eects were found on albumen weight and eggshell weight （ P< （2 0.05），with both parameters being higher in the 105% group，though no significant differences were detected in the proportion of egg components among groups （ P>0.05 ）.（3）Regarding eggquality parameters，no significant efects were observed on albumen height， Haugh unit，eggshell strength，，or eggshell thickness （ P>0.05 ），while the egg shape index was significantly influenced，reaching its highest value in the 105 % group （ P <0.05）.In conclusion，under the experimental conditions，when evaluated against key productionindicatorsincludinglayingrate，feed-to-egratio，andeggquality，thecurrentstandardof“NutrientRequirementsof Laying Ducks”（GB/T41189-2O21）wasdemonstrated tomeetproductiorequirements.However，itisrecommendedthatthe nutrientlevelbeadjusted to95%when theeggbreakage rate is incorporatedasanadditional evaluationcriterion.
