Comparative nutrient digestibility in different ingredients fed to Duroc × Landrace × Yorkshire and Duroc × Berkshire × Jiaxing growing barrows

Evaluating the Effect of Adaptation Length on Apparent Ileal and Total Tract Digestible Energy of Corn and Wheat Middlings in Growing Pigs

“…This result is consistent with what has previously been reported [14,[26][27]. In comparison to what has been reported [13], where ileal EN digestibility values of corn and WM in the DLY breed of pigs were 81.5 and 40.5, respectively, a decrease of 50%, the current study observed a decrease of 48% (corn=73.1 and WM=38.4%). This difference can be attributed to an increase in the fiber level of WM compared to corn.…”

“…For the total tract data, the respective values were 6.6% (DM), 6.6% (EN) digestibility, and 366 kcal/kg (DE). High level of fiber has been reported to always result in a decrease of ileal and total tract digestibility values [13,24,25]. Apparent ileal DM and EN digestibility obtained from the current study is similar to what has been previously reported [22].…”

“…This has been attributed to the increased level of the anti nutritive dietary insoluble fiber [23]. A lower ileal and total tract GE digestibility in a corn-SBM-WM-based diet (WM replaced 25% of corn and SBM in the basal diet) compared to corn-based diet has been reported [13]. This difference between the corn-based and corn-SBM-WM-based diets in DM, N, and EN digestibility was more pronounced in the ileal (EN digestibility: 81.5 vs 43.6%) compared to total tract (EN digestibility: 83.5 vs 72.2%) values for the pigs in the same study [13].…”

In the current study, the corn-SBM-based reference diet had a higher ileal DM (11.0%-points) and EN (10.8%-points) digestibility, as well as DE (552 kcal/kg) compared to the corn-SBM-WM-based diet.…”

Physiological function and application of dietary fiber in pig nutrition: A review

“…The study of Urriola and Stein (2012) reported that Meishan pigs fed 29.1% corn DDGS diets had significantly higher ATTD of TDF than Yorkshire pigs. When fed with high-fiber diets containing 24.1% wheat meal, alfalfa meal or rice bran, Duroc × Berkshire × Jiaxing pig showed a higher hindgut ADF digestibility than Duroc × Landrace × Yorkshire pigs, indicating the offspring of the three-way hybrid of the indigenous breeds still retained a high ability of fiber degradation ( Zhao et al., 2018a ). However, there has been no systematic study focusing on the reasons as to why indigenous pigs have better fiber digestibility than cultivated pigs until now.…”
