“…According to Honig and Wolf (1991), phytic acid and phytate may form complexes with protein and free AA at pH values normally occurring in the small intestine of the pig. The interaction between phytate and protein may provoke changes in protein structure that can decrease enzymatic activity, and protein solubility and digestibility (Greiner and Konietzny, 2006).…”

The effects of phytase supplementation on the apparent ileal digestibility (AID) of amino acids (AA) have been inconsistent. Two experiments evaluated the effect of providing a mixture of pancreatic enzymes (Pancreatin(®) ) to growing pigs fed sorghum-soybean meal diets supplemented with phytase on the AID of AA, energy, and phosphorus (P), as well as the ileal digestibility (ID) of phytate; there were four periods per experiment. In Experiment 1, eight pigs (BW 22.1±1.3 kg) were fitted with a T-cannula at the distal ileum. Each period consisted of 9 days; 7 days for diet adaptation, and 2 days for digesta collection. Treatments (T) were: (i) basal sorghum-soybean meal diet, (ii) basal diet plus Pancreatin®, (iii) basal diet plus phytase and (iv) basal diet plus phytase and Pancreatin®. Phytase increased the digestibilities of phytate and P (p<0.001), but did not affect the AID of AA and energy (p>0.10). Except for methionine (p=0.07), Pancreatin® did not affect the AID of AA. Phytase and Pancreatin® did not interact (p>0.10). Experiment 2 was similar to Experiment 1, but Pancreatin® was infused into duodenum. Pancreatin® infusion did not affect the AID of AA (p>0.10); and tended to reduce (p=0.09) the AID of lysine. Phytase × Pancreatin® interactions were not observed (p>0.10). In conclusion, phytase and Pancreatin® did not improve the AID of AA in growing pigs fed sorghum-soybean meal diets indicating that phytates did not affect AA digestibility.

“…These salts are unavailable for absorption from the gastrointestinal tract (Morris and Ellis, 1976). Phytic acid is also able to form complexes with protein (Scheuermann et al, 1988;Gifford and Clydesdale, 1990;Honig and Wolf, 1991) and to inhibit a-amylases, trypsin, tyrosinase, and pepsin (Nair et al, 1991;Caldwell, 1992). Partial hydrolysis of phytic acid in practical diets for pigs may be J. h i m .…”

Five barrows of approximately 45 kg BW, fitted with post-valvular T-cecum cannulas at the ileo-cecal junction, were assigned randomly to five treatments (5 x 5 Latin square design) to assess the effect of microbial phytase and feeding regimen (frequency and level) on the apparent digestibilities (total tract [ATTD] and ileal [AID]) and retention of nutrients. A corn-tapioca-soybean meal diet of low intrinsic phytase activity, containing no added inorganic P, was fed either without or with microbial phytase from Aspergillus niger var. Van Tieghem (800 phytase units/kg of diet) at different feeding frequencies (once, twice, or seven times per day) and feeding levels (2.3 vs 2.8 times the maintenance requirement for ME, i.e., 418 kJ ME/BW.75). Microbial phytase enhanced significantly the ATTD of DM, OM, CP, Ca, total P, and amino acids (except for cystine and proline). Also, the AID of total P, phytic acid, methionine, and arginine was increased (P < .05 or .01). As a consequence of adding this enzyme, the retention (grams/day) of N, Ca, and P was greater (P < .01) and their daily excretion was diminished by 5.5, 2.2, and 1.9 g/d, respectively. The feeding level exerted a minor effect on the ATTD and AID (except for methionine and cystine), although the retention (grams/day) of N, Ca, and P was greater (P < .01) at the higher level of feeding. The feeding frequency influenced significantly the ATTD of Ca, tryptophan, and isoleucine and the AID of phytic acid, cystine, arginine, isoleucine, and phenylalanine. Also, N retention (grams/day) was reduced in pigs fed once daily (P < .01).

Effect of pea and soya bean interaction on zinc dialyzability in weaning foods

Higher values are reported for Zn dialyzability of homogenized infant formulas when pea content is high and soya bean content is low, but also when the reverse is the case, ie low pea content and high soya bean content. This apparent paradox is examined in terms of a potential antagonistic effect of the pea × soya bean interaction on Zn dialyzability. The antagonistic effect is traced to the linear combined effect of the two ingredients on pH over a narrow interval around 5.90 and on calcium content. This combined effect may account for the difference in results between in vivo and in vitro studies reported by several authors. The combination of certain vegetables in an infant formula may, in certain circumstances, enhance Zn dialyzability, contradicting the general view that increased legume content diminishes Zn dialyzability due to an increase in phytic acid levels.
