      Energy of Corn- and Wheat-Based Diets in Growing Pigs.

AB  - This study aimed to evaluate the effects of optimal carbohydrase mixture (OCM) on 
      macronutrients and amino acid digestibility and the digestible energy (DE) in 
      growing pigs fed the corn-soybean meal-based diet (CSM) and the wheat-soybean 
      meal-based diet (WSM). A total of 36 ileal-cannulated pigs (50.9 +/- 4.9 kg initial 
      body weight) were allotted to four dietary treatments randomly, which included 
      CSM and WSM diets, and two diets supplied with corresponding OCM. These OCMs were 
      screened using an in vitro method from our previous study. After the five day 
      adaptation period, fecal samples were collected from d six to seven, and ileal 
      digesta samples were collected on d 8 and 10. Chromic oxide was added as an 
      indigestible marker. The results show that the addition of OCM improved the 
      apparent ileal digestibility (AID) of dry matter (DM), ash, carbohydrate (CHO), 
      neutral detergent fiber, and gross energy (GE) and the apparent total tract 
      digestibility (ATTD) of DM, CHO, and GE in CSM diet (p < 0.05), but reduced the 
      apparent hindgut disappearance (AHD) of DM in CSM diet (p < 0.05). The ATTD of 
      DM, crude protein (CP), ether extract (EE), ash, and GE and the AHD of DM, CP, 
      EE, ash, CHO, and GE in WSM diet were improved by the OCM addition (p < 0.05), 
      whereas the AID of DM, CP, ash, CHO, and GE were decreased (p < 0.05). The 
      respective DE contents in CSM and WSM diets were increased from 15.45 to 15.74 
      MJ/kg and 15.03 to 15.49 MJ/kg under the effects of OCM (p < 0.05). Similar to 
      the trend of AID of CP, the OCM addition increased the AID and standardized ileal 
      digestibility (SID) of Ile, Thr, and Cys in CSM diet, but decreased the AID and 
      SID of Ile, Phe, Thr, Val, Ala, Pro, Ser, and Tyr in WSM diet. In conclusion, the 
      OCMs screened by an in vitro method could improve the total tract nutrient 
      digestibility and DE for pigs fed corn-based diet or wheat-based diet but had 
      inconsistent effects on the ileal digestibility of nutrients and energy.
