Effect of Fermented Feed on Nutrient Apparent Digestibility of Piglets.

In order to analyze the effect of fermented feed on the production performance, slaughter performance, digestion and metabolism of nutrients and economic benefits of piglets, this paper analyzes the effect of fermented feed (taking grape pomace residue as example) on the nutrient apparent digestibility of piglets. Through the determination of tannin content in grape pomace residue, the nutritional value of grape pomace residue was evaluated, and the influence of feed with different grape pomace residue content on the nutrient apparent digestibility of piglets was analyzed, which provided scientific basis for the rational development and utilization of grape pomace residue and pig breeding. The results showed that grape pomace residue had a promotion effect on the nutrient apparent digestibility, production performance, slaughter performance, digestion and metabolism of nutrients and economic benefits of piglets, so it is an ideal feed material of piglets.
