“…These data are consistent with the average values published by NRC [6]. Barley has a greater concentration of fiber and a reduced concentration of starch compared with corn while the digestibility of starch in barley is lower than in wheat and corn [17,18]. The analyzed GE as well as the nutrient profile of HF and LF barley used in the current study were 4,447 and 4,448 kcal GE, 13.98% and 12.96% for CP as well as 2.64% and 2.57% for EE.…”

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.

“…A recent study by Cervantes-Pahm et al (163) reported on the use of a pig model to investigate the comparative nutrient and energy digestibility of a range of grains widely used for human consumption, including wholegrain sorghum. In this study, the apparent ileal digestibility of sorghum starch was lower than for corn.…”

“…In this study, the apparent ileal digestibility of sorghum starch was lower than for corn. (163) The authors attributed this to the high level of resistant starch in sorghum, which appeared to be fully fermented in the pig hindgut since ~100% starch disappearance was reported. The low apparent ileal digestibility of its starch in pigs suggests that sorghum may be of value for reducing the glycemic index of human foods.…”

“…The low apparent ileal digestibility of its starch in pigs suggests that sorghum may be of value for reducing the glycemic index of human foods. (163) Caution in extrapolating these pig trials to human health is needed, since in this study raw grains were used, whereas in human food the grains are invariably cooked, changing the structure and digestion properties of the starch.…”

“…Considered as a prebiotic carbohydrate, low digestibility of RS resulted in decreased apparent ileal and total tract digestibilities of nutrients (Gerrits et al., ; Cervantes‐Pahm et al., ). Hence, a low plasma glucose concentration was observed in pigs fed high‐RS diet (Giuberti et al., ).…”

In the present study, the effects of dietary resistant starch (RS) content on serum metabolite and hormone concentrations, milk composition, and faecal microbial profiling in lactating sows, as well as on offspring performance was investigated. Sixteen sows were randomly allotted at breeding to two treatments containing low- and high-RS contents from normal and high-amylose corn varieties, respectively, and each treatment had eight replicates (sows). Individual piglet body weight (BW) and litter size were recorded at birth and weaning. Milk samples were obtained on day 10 after farrowing for composition analysis. On day 2 before weaning, blood and faecal samples were collected to determine serum metabolite and hormone concentrations and faecal microbial populations, respectively. Litter size at birth and weaning were not influenced (p > 0.05) by the sow dietary treatments. Although feeding the RS-rich diet to sows reduced (p = 0.004) offspring birth BW, there was no difference in piglet BW at weaning (p > 0.05). High-RS diet increased (p < 0.05) serum triacylglycerol and nonesterified fatty acid concentrations and milk total solid content, and tended (p = 0.09) to increase milk fat content in lactating sows. Feeding the RS-rich diet to sows increased (p < 0.01) faecal bacterial population diversity. These results indicate that high-RS diets induce fatty acid mobilization and a greater intestinal bacterial richness in lactating sows, as well as a greater nutrient density in maternal milk, without affecting offspring performance at weaning.

Comparative digestibility of energy and nutrients and fermentability of dietary fiber in eight cereal grains fed to pigs

Abstract: Dehulled oats provide more energy to diets and should be used if the goal is to increase caloric intake. In contrast, sorghum and rye may be more suitable to control diabetes and manage body weight of humans.
