چکیده
Increasing prevalence of antibiotic resistance due to its indiscriminate use in poultry production is an emerging public health issue. This has prompted research on viable alternatives that will improve performance birds. study was designed evaluate the effect humic acid supplemented diets and microbial load laying hens. Fifty-four 20-week old Isa brown hens were randomly distributed into three dietary treatments consisted six replicates with birds per replicate a completely randomized design. Treatment 1 basal diet (control diet) no supplementation while 2 3 had 0.2% 0.4% acid, respectively evaluated 42-day feeding trial. Performance parameters evaluated. On day 42, egg quality attributes measured. Birds slaughtered digesta samples from ileum collected for count. Data obtained analyzed using descriptive statistics ANOVA at á0.05. fed highest final weight (1721g/bird) gain (97.83g/bird). A decrease observed 0% (-168.17g/bird) (-24.17g/bird) diets. Higher (P < 0.05) yolk height width recorded as compared control diet. Lowest colour (2.33) found (4.16) Similarly, Haugh unit (78.09) shell (7.83g) Least total heterotrophic count (1.10 x 10 CFU/ml) Lactobacilli (0.23 diet.In conclusion, up can serve replacement growth promoter improved gut birds.
 
 La prévalence croissante de la résistance aux antibiotiques en raison son utilisation inconsidérée dans avicole est un problème santé publique émergent. Cela suscité des viables qui stimuleront réponse immunitaire oiseaux et amélioreront les performances production. Cette étude été conçue pour évaluer l'effet régimes alimentaires enrichis acide humique sur charge microbienne chez poules pondeuses. Cinquante-quatre brunes âgées 20 semaines ont réparties au hasard trois traitements diététiques composés répétitions avec par répétition plan complètement randomisé. Le traitement était le régime base (régime témoin) sans supplémentation humique, tandis que avaient complété 0,2 % d'acide 0,4 évalués respectivement essai d'alimentation 42 jours.
