Digestibility of dietary fiber by growing pigs
… AID and the apparent total tract digestibility (ATTD) of energy and TDF were lower in the diet with 30% DDGS (81.0 and 55.5%) than in the control diet (86.0 and 60.0%), but that reduction could not be explained by changes in gut transit time, or by changes in concentration of volatile fatty acids …

Comparative digestibility of energy and nutrients in diets fed to sows and growing pigs
… DE, ME, and apparent total tract digestibility (ATTD) of nutrients is greater in gestating sows fed close to the maintenance requirement than in growing pigs allowed ad libitum access to diets. Therefore, there is a need in North America to generate separate digestibility values for gestating …

Digestibility of calcium and phosphorus and effects of microbial phytase in diets fed to growing pigs or gestating sows
… STTD of Ca, apparent total tract digestibility (ATTD), and retention of Ca and P does not change during gestation. Throughout gestation, sows were fed 4 diets that were Ca-free diet or a corn-based diet in which Ca carbonate was the sole source of Ca without or with microbial phytase. Results …

Effects of exogenous enzymes alone or in combination with oligosaccharides on utilization of total dietary fiber, fermentation, growth performance, and health of weanling and growing pigs
… the apparent total tract digestibility (ATTD) of gross energy and TDF, and therefore, increase metabolizable energy (ME) in high fiber diets for pigs was tested. Results indicated that pigs fed the high dose of the combination of xylanase and β-glucanase tended to have greater (P < 0.10) …

Composition and digestibility of different sources of feed phosphates by growing pigs
… that the apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P were not different between MCP and MSP from volcanic deposits and MCP and MSP from non-volcanic deposits. Values of digestibility were in agreement with previous data for STTD of P in MCP …

Use of feed technology to improve nutritional value of feed ingredients fed to pigs
… the exception of Trp, Cys, Pro, and Ser. The ATTD of NDF, ADF, and AEE was greater (P < 0.01) in conventional DDGS than in Dakota Gold DDGS, but there was no difference in the ATTD of GE between the 2 sources of DDGS. Study 2, was conducted to determine the effects of including Dakota Gold or …

Avocado meal: A novel dietary fiber source in feline and canine diets
… and apparent total tract digestibility (ATTD). Fresh fecal samples were analyzed for phenols, indoles, ammonia, short-chain fatty acids [SCFA (acetate, propionate, and butyrate)], and branched-chain fatty acids [BCFA (isobutyrate, isovalerate, and valerate)]. Extrudate samples for all …

Evaluation of red and white sorghum as alternative carbohydrate sources and the effects of extrusion in monogastric nutrition through the determination of macronutrient digestibility, fecal microbiota, digestible and metabolizable energy content
… the dogs and apparent total tract digestibility (ATTD) for dry matter (DM), organic matter (OM), crude protein (CP), and acid hydrolyzed fat (AHF) were not different from corn (P > 0.05). Digestibility values for all those criteria were >80% and metabolizable energy was consistent for all dietary …

Effects of microbial phytase on the standardized total tract digestibility of phosphorus in soybean meal, corn, and corn co-products
… < 0.01) the apparent total tract digestibility (ATTD) of P in the diets. Absorption of P was greater (P < 0.05) for pigs fed corn-SBM-DDGS diets than for pigs fed corn-SBM diets, and phytase, DDGS, or the combination of phytase and DDGS, reduced (P < 0.01) P excretion. In Exp. 4 and 5, the …

Novel soybean products fed to weanling pigs
… that the apparent total tract digestibility (ATTD) of P in HP-310 and SBM increased (P < 0.05) as phytase was included in the diet (from 59.8 to 77.7% for HP-310 and from 65.5 to 79.5% for SBM), but the ATTD of P in HP-340 was not different (83.8 and 87.7%, respectively). These results …
