“…The ATTD of DM, GE, OM, NDF, and ADF in dehulled barley were increased compared with the unprocessed hulled barley confirming the fact that DE and ME levels were improved due to partial dehulling of barley. The digestibility and retention rate of N were not changed in the current study and this is consistent with the results reported by Hennig et al [ 22 ]. The decreases in digestibility and metabolizability of energy are presumably related to the relatively high fiber concentration in barley compared with corn.…”

“…Partial dehulling reduced GE slightly whereas the levels of ADF and NDF were decreased by 27.8% and 33.4% in HF as well as 49.1% and 28.0% in LF, respectively. Hennig et al [ 22 ] showed that partial dehulling reduced the levels of ADF and NDF to a greater extent in two-row barley than in six-row barley varieties. The content of total dietary fiber and insoluble dietary fiber in DLF were decreased more than in DHF in comparison with LF and HF, respectively.…”

“…The concentrations of the essential AA in the two dehulled barleys were higher than the two unprocessed barleys used in the present experiment. Similarly, the concentrations of all selected AA including Lys, Met, Cys, Thr, and Try were higher in dehulled two-row barley and six-row barley compared with intact seeds [ 22 ].…”

ObjectiveThe hull attached to the barley kernel can be mechanically removed thus reducing the fiber content of the barley. This experiment was carried out to evaluate the effects of partial dehulling on the nutrient digestibility as well as the digestible energy (DE) and metabolizable energy (ME) content of barley in pigs.MethodsTwo hulled barley samples (high fiber barley [HF] and low fiber barley [LF]) with either high or low fiber contents were obtained from the Hubei and Jiangsu Provinces of China. A portion of the two barleys was mechanically dehulled (dehulled high fiber barley [DHF] and dehulled low fiber barley [DLF]). Thirty barrows (initial BW = 31.5±3.2 kg) were assigned to one of five diets in a randomized complete block design. The five diets consisted of 96.9% corn, HF, LF, DHF, or DLF supplemented with 3.1% minerals and vitamins. Each diet was fed to six barrows housed in individual metabolism crates for a 10-d acclimation period followed by a 5-day total but separate collection of feces and urine.ResultsThe daily loss of gross energy (GE) in feces was lower (p<0.01) for pigs fed DHF than for those fed HF. The daily N intake and fecal N loss were lowest (p<0.01) for pigs fed the corn diet. The DE and ME as well as the apparent total tract digestibility (ATTD) of dry matter, GE, organic matter, neutral detergent fiber (NDF) and acid detergent fiber (ADF) of DHF or DLF were higher (p<0.01) than the values in HF and LF, respectively while the values except the ATTD of NDF and ADF in DLF were higher (p<0.01) than the values in DHF and were comparable to corn.ConclusionThe DE and ME contents as well as the ATTD of nutrients in both DHF and DLF barley were improved compared with the HF and LF barley. Moreover, the nutritive value of DLF barley was comparable to the yellow-dent corn used in the study.
