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. |
