Abstract:Miscellneous meal refers to the by-product from oil crops after extraction,including rapeseed meal, cottonseed meal,peanut meal and sunflower seed meal.Ithas high yieldand lowprice,and isrich in protein,fat, and minerals,which make itavaluableunconventional feedstock.However,thehighlevelsofanti-nutritionalfactors presentsuch ascrude fiber,tannins,phytic acid and thioglycosidein miscellaneous meal not only impede the digestionandabsorptionof nutrientsbutalsohave toxicological effects,severelyconstraining thefeedutilizationof miscellaneous meal.With the advancementand widespread adoption of biotechnological approaches in animal feed production,fermentationoffeedraw materialsofersadistinctiveadvantage.Microbial fermentation facilitates the reductionof anti-nutrition factors inmiscellaneous mealand breaks down indigestibleorpoorlyutilized components intoreadilyabsorbablesmall molecules,enhancing digestionandutilization effciencyof animals.Currently,lactic acidbacteria,bacilus,yeast,and mold are the predominant microorganismsemployed inthe fermentationof miscellaneous meals.Fermentationalso generatesvaluable metabolites,providing arich source of probiotics for animals.Reasonableutilizationof miscelaneous meal notonlysave conventionalfeed resources,allviate the shortage of domestic feedresourcesand the situationof“humanandanimal competition for food”,butalsoadress environmental pollution caused bywaste discharge.Miscellaneous meal has broad applicationprospects inanimal production.This paperreviews thenutritionalvalueof miscellaneous meal,changes innutritional componentsandantinutritionalfactorsbeforeandafter fermentation,aswellastheapplicationefectoffermentedfeed inbroiler production.Italsosummarizes the current challenges in theutilization of miscelaneous meal,inorder to provide theoretical basis forthe application of fermented miscellaneous meal in broiler production.
