Nutrient digestibility of lentil and regular- and low-oligosaccharide, micronized full-fat soybean fed to grower pigs1

Abstract

A study was conducted to determine the standardized ileal digestibility (SID) of AA and calculate the NE value for regular-oligosaccharide, micronized full-fat soybean (R-MFFSB), low-oligosaccharide, micronized full-fat soybean (LO-MFFSB), lentil, and enzymatically hydrolyzed casein (EHC) for growing pigs. Six ileal-cannulated barrows (31.4 kg BW) were fed 6 diets in a 6 × 6 Latin square. Five diets were cornstarch based, containing either soybean meal (SBM), R-MFFSB, LO-MFFSB, or EHC as sole protein source or N free. The sixth diet contained lentil as sole protein and energy source. The SID of AA for diets was calculated using the N-free diet. Digestibility of AA in feedstuffs was determined by the direct method. Energy digestibility in SBM, R-MFFSB, and LO-MFFSB was determined by difference from the N-free diet whereas energy digestibility in lentil was determined by the direct method. On DM basis, SBM, R-MFFSB, LO-MFFSB, and lentil contained 52, 43, 43, and 27% CP, 8, 12, 14, and 16% NDF, and 1.8, 19, 21, and 1.6% ether extract, respectively. The SID of Lys for SBM was greater (P < 0.05) than that for R-MFFSB or LO-MFFSB (76 vs. 79 and 79%). The SID of other indispensable AA (except Trp) for SBM was also greater (P < 0.05) than that for R-MFFSB or LO-MFFSB. The R-MFFSB and LO-MFFSB were similar in SID of AA. The SID of Lys for lentil (81%) was lower (P < 0.05) than that for SBM with a similar trend for SID of other indispensable AA except for Met and Thr whose SID was similar to SBM. The SID of AA for EHC ranged from 98 to 112%. The SBM had a lower (P < 0.05) NE value than R-MFFSB or LO-MFFSB (2.63 vs. 2.95 and 3.00 Mcal/kg DM). Lentil and SBM were similar in NE value (2.60 vs. 2.63 Mcal/kg DM). In conclusion, R-MFFSB and LO-MFFSB were similar in energy and AA value for pigs. Lentil had lower SID of AA than SBM. However, lentil and SBM were similar in NE value; therefore, lentil can serve as alternative pulse feedstuff for pigs. The AA in EHC were mostly completely digested indicating that EHC can be fed to estimate ileal endogenous AA losses.

“…Also, the TI activity of the CPCC was higher than the value (<1.0 TIU/ mg) that was reported by Almeida et al (2013) for canola meal, which is another co-product of the Brassica family. The TI activity of the SBM was similar to the values (3.20-6.21 TIU/mg) that were reported by others (Valencia et al, 2008;Goebel and Stein, 2011;Perryman and Dozier III, 2012;Woyengo et al, 2014). In addition to TI activity, camelina co-products, like most of the other co-products of the Brassica family, contain high levels of glucosinolates (Almeida et al, 2013;Kahindi et al, 2014), which reduces voluntary feed intake because of their bitterness (Lee and Hill, 1983;Mailer et al, 2008).…”

“…Also, basal ileal endogenous AA losses were comparable to values reported by Shi et al (2015) for growing pigs fed N-free diet. However, the basal ileal endogenous AA losses were greater than the values that were reported by Zhai and Adeola (2011), Woyengo et al (2014), and Woyengo et al (2016b) for growing pigs fed N-free diet. Recently, Adeola et al (2016) reviewed the methods of estimation of basal ileal endogenous AA losses in pigs, and concluded that basal ileal endogenous AA loss values from pigs fed N-free diet are lower than those from pigs fed low casein cornstarch-based diet.…”

“…Recently, Adeola et al (2016) reviewed the methods of estimation of basal ileal endogenous AA losses in pigs, and concluded that basal ileal endogenous AA loss values from pigs fed N-free diet are lower than those from pigs fed low casein cornstarch-based diet. Thus, the differences between the current study and those of Zhai and Adeola (2011), Almeida et al (2013), Woyengo et al (2014), and Woyengo et al (2016b) with regard to basal ileal endogenous AA losses could have been due to differences in composition of diets fed in the studies. The SID of Pro for diets was greater than 100%, which was similar to results of Dilger et al (2004), Opapeju et al (2006), Woyengo et al (2010), and Woyengo et al (2016b) who reported SID of Pro values that were greater than 100%.…”

“…The nitrogen retained in diets with co-products is not affected when the imbalances in the amino acid concentrations or the post-absorptive energy metabolism of diets is taken into account [7]. In recent years, the ME or the DE systems have been substituted gradually by the NE system in pig husbandry of North America and Europe [8].…”

Digestibility of Amino Acids in Protein-Rich Feed Ingredients Originating from Animals, Peanut Flour, and Full-Fat Soybeans Fed to Pigs

“…Other potential dietary protein sources may be of plant origin, such as peanut flour (PF) and full-fat soybean (FFSB). Although FFSB contains high concentrations of crude protein (CP) and energy [7,8], it also contains a considerable amount of trypsin inhibitors that limits its use in swine diets. Alternatively, PF produced from dehulling and grinding peanuts contains high CP [9], which makes it another potentially valuable protein source for pigs.…”
