Abstract: China is rich in fruit resources,and fruit pomace is a good feed resource because of its huge output,variety and rich nutrition.With the in-depth research,it is revealed that pomace of apple,citrus,pineapple,grape and sea bucktron contain nutrient components including crude protein (CP),crude fiber (CF) and ether extract (EE) and mineral element including calcium,phosphorus,copper,zinc,iron,selenium and magnesium,meanwhile it is rich in active substance such as vitamin,flavonoid,polysaccharides and polyphenols.Therefore,pomace has good feeding value.However,it also has some flaws such as bad palatability and low digestive rate because of its antinutritional substance like cellulose,xylogen,pectin and tannin,which affects digestive and absorptive function and feed conversion rate in animal.While microbial fermentation process can improve its nutrient structure,nutrient value and utilization rate by reducing its antinutritional components of cellulose,xylogen,phytic acid,pectin and tannin,and increase nutrient contents of crude protein and amino acids.It is discovered that fermented pomace as feed could improve growth performance,production performance and meat quality,and decrease cost in livestock breeding.Combined with domestic and abroad researches,the nutrient value of fruit pomace,nutritional changes after microbial fermentation and the application of the fermented pomace in livestock breeding were reviewed here.The aim of this paper is to clarify the application value,economic value and social value of microbial fermented fruit pomace,and provide theoretical reference for the deep excavation and popularization of fermented pomace as feed in livestock breeding.

Key words: fruit pomace; nutrient value; fermented feed; livestock
