Studies on dietary fiber and nutrient bioavailability have gained an increasing interest in both human and animal nutrition. Questions are increasingly being asked regarding the faith of nutrient components such as proteins, minerals, vitamins, and lipids after feed formulation. The aim of this review is to evaluate the evidence with the perspective of fiber usage in feed formulation. The consumption of dietary fiber may affect the absorption of nutrients in different ways. The physicochemical factors of dietary fiber, such as fermentation, bulking ability, binding ability, viscosity and gel formation, water-holding capacity and solubility affect nutrient absorption. The dietary fiber intake influences the different methods in which nutrients are absorbed. The increase in the total fiber content of the diet may delay the glycemic response. Soluble fiber decreased blood glucose content whereas purified insoluble fiber has a little or no effect on the blood glucose levels after a meal. Dietary fiber and prebiotics influence the host animal well-being by regulating blood glucose or insulin levels, stool bulking effects, increasing the acidity of the gut, constructive synthesis of short chain fatty acids (SCFAs), decreasing intestinal transit time, stimulating the growth of intestinal microbes, and increasing blood parameters. Previous studies suggest that fiber affects the bioavailability of nutrients, and maintains the host wellness.

“…Phytate has been shown to affect the availability of nutrients other than P, including protein, carbohydrates, and other minerals because the binding capacity of phytate is reduced as phosphate groups are removed and the complex becomes more soluble (Harland and Morris 1995). This increase in solubility is confirmed in the current trial by the improvements in CP and ash digestibility with the addition of phytase to Phase III diets.…”

. M. 2010. Body weight gain and nutrient utilization in starter pigs that are liquid-fed high-moisture corn-based diets supplemented with phytase. Can. J. Anim. Sci. 90: 45Á55. A total of 384 starter pigs were used to examine the application of exogenous phytase in high-moisture corn (HMC)-based liquid diets. Pigs were randomly assigned to 24 pens in six blocks. Pens were randomly assigned one of four HMC-based diets formulated to vary in total phosphorus (P) content (Low, Medium and High), with phytase added to only the Low P diet (Phy). Body weight gain and feed intake were monitored until body weight exceeded 20 kg. Apparent total tract digestibility of crude protein and P were measured on day 21 (Phase II) and day 42 (Phase III). At the end of the trial, two pigs from each pen were sacrificed for analysis of carcass composition and evaluation of metacarpals. Pigs fed the Phy treatment had increased digestibility of crude protein (P B0.05) and P (P00.062) in Phase III, and increased metacarpal breaking strength (PB0.01) and P content (PB0.05). Average daily gain, feed intake, and carcass composition were not affected by treatment (P0.05). In conclusion, performance of starter pigs fed liquid HMC-based diets was maintained at dietary P levels below established requirements, but addition of phytase improved bone strength and mineralization. This study provides evidence for the effectiveness of phytase, and that P requirement for maximum rate of weight gain in pigs is not sufficient for maximum skeletal development.Key words: High-moisture corn, liquid feed, phosphorus, phytase, starter pigs Columbus, D., Zhu, C.

“…Certains acides aminés peuvent être synthétisés et la biodisponibilité des vitamines du groupe B accrue (Chavan et al, 1989, Blandino et al, 2003. La fermentation favorise l'obtention d'un pH optimal pour la dégradation enzymatique des phytates qui sont présents dans les céréales sous formes complexées avec les protéines et certains minéraux tels que le fer, le zinc, le magnésium (Harland,Morris, 1995). Une réduction des phytates peut augmenter la quantité de fer soluble, de zinc et de calcium.…”
