Effects of distillers' dried grains with solubles and soybean oil on dietary lipid, fiber, and amino acid digestibility in corn-based diets fed to growing pigs.
J Anim Sci. 2016 Apr; 94(4):1508-19.JA

Abstract

The use of corn coproducts increases the concentration of fiber and, often, the use of supplemental lipids in swine diets, which may affect energy and nutrient digestibility. An experiment was conducted to determine the effects of reduced-oil distillers' dried grains with solubles (DDGS) and soybean oil (SBO) on dietary AA, acid hydrolyzed ether extract (AEE), and NDF digestibility in corn-based diets fed to growing pigs. Eighteen growing pigs (33.8 ± 2.2 kg BW) were surgically fitted with a T-cannula in the distal ileum and allocated to 1 of 6 dietary treatment groups in a 3-period incomplete Latin square design, with 9 observations per treatment. Six dietary treatments were obtained by adding 0, 20, and 40% DDGS to corn-casein diets formulated with 2 and 6% SBO. Ileal digesta and fecal samples were collected and the apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of AEE and NDF and the AID of AA were determined. Apparent values were corrected for endogenous losses of lipids, and true ileal (TID) and true total tract digestibility (TTTD) values of lipids were calculated. Results showed that the AID of Lys decreased (< 0.001) with the inclusion of DDGS but was not affected (= 0.63) by the inclusion of SBO. An interaction between DDGS and SBO on the AID (= 0.002) and ATTD (= 0.009) of NDF was observed, where the AID and ATTD of NDF decreased with DDGS at 6% SBO but no effect was observed at 2% SBO. The AID of NDF increased with SBO at 0% DDGS, but no effect was observed at 20 or 40% DDGS. An interaction between DDGS and SBO on the AID (= 0.011) and ATTD (= 0.008) of AEE was observed, where the AID and ATTD of AEE increased with SBO. The AID and ATTD of AEE increased with DDGS at 2% SBO, but no effect was observed at 6% SBO. Correction by ileal and fecal endogenous loss of AEE (9.5 and 13.6 g/kg of DMI, respectively) showed that increasing dietary AEE had no effect on the TID and TTD of AEE (> 0.05). In conclusion, the AID of Lys decreased with DDGS and was not affected by lipids from SBO. The greatest AID and ATTD of NDF was observed in diets with a high AEE and low NDF content. Low values of apparent digestibility of AEE in lower-lipid diets are possibly the result of endogenous losses of lipids, because the true digestibility of AEE was not affected by the dietary increase of AEE.
