Anti-nutritional factors can bind to nutrients, making them harder for the animal to digest.

Not all antinutritional factors affect animals differently. For example, trypsin inhibitors and phytic acids are not consider antinutritional factors for ruminants but are for poultry and swine. Some factors can be minimized with correct processing of the feedstuff like heat treatment in soybean meal to reduce trypsin inhibitors. Other factors can be prevented with proper harvest, transport, and storage of feedstuffs (think about mycotoxins and microbial contamination). How to deal with antinutritional factor(s) present in a feed ingredient will depending on the factor and its level.
Can you be more specific about what type of antinutritional factor(s) is affecting your feed ingredient(s)? -

There are many types of antinutritional factors that can be divided in two main groups: intrinsic and extrinsic. Intrinsic factors are unique compounds present in different ingredient like trypsin inhibitors in soybean meal, tannins in sorghum, gossypol in cotton seed meal, lectins and alkaloids in some legumes, glucosinolates in canola meal, phytic acid in vegetable feedstuffs, and more. Extrinsic antinutritional factors do not belong per se to the ingredient but can be present in ingredient due to contamination. Example of extrinsic factors include toxins (like mycotoxins and others), microbial contamination (e.g., E. coli, Salmonella, etc.), and chemical contamination (e.g., pesticides, herbicides, etc.). Antinutritional factors will affect the performance of animals in four main ways: 1) interference with the digestive process, 2) alteration of intestinal permeability, 3) alteration of the microbiota, including presence of intestinal pathogens, and 4) alterations of the normal metabolism of animal.

Anti-nutritional factors can cause the animal to grow more slowly and be less efficient at using feed.
