“…However, the pigs fed the HF diet had significantly higher OM, NSP, NCP, and cellulose digestibility in week 6 than in week 12. This has also been found in a previous study where younger pigs were found to have higher ATTD of DM compared with older pigs on barley-based diet (Beames and Ngwira, 1978). Angelis et al (2015) reported that Bacteroides, Porphyromonas, and Prevotella spp., which are related to DF degradation, were decreased due to barley β-glucan.…”

Research on effects of different fiber types and levels on infection with Brachyspira hyodysenteriae on growth performance and nutrients digestibility in pigs is scarce. The objective of the current study was to investigate the effects of infection with B. hyodysenteriae when feeding diets varying in soluble and insoluble dietary fiber (DF) on the expression of swine dysentery, growth performance and digestibility of organic matter (OM) nutrients. A total of 96 growing pigs (26.9 ± 2.5kg) were used for the experiment and divided into 6 blocks. The growing pigs were fed one of four diets for 12 weeks: Low fiber (LF), high fiber (HF), high soluble fiber (HS) and high insoluble fiber (HI). After two weeks, half of the pigs were inoculated with B. hyodysenteriae. Half of the pigs in each group were euthanized at week 6 for measurement of the apparent digestibility at ileum, cecum, colon and total tract. The remaining pigs were maintained to observe and analyze clinical expression of fecal score and excretion of B. hyodysenteriae, growth performance and total tract digestibility up to 12 weeks. In the current study, the experimental diets did not influence the expression of infection in the pigs. The body weight (BW) and average daily gain (ADG) were in line with the results of clinical expression from week 4 to 6. However, the ADG of the infected pigs started to recover from week 6 (P < 0.05), and then recovered from week 8 to 12 (P < 0.05). The infection with B. hyodysenteriae did not impair apparent ileal digestibility (AID; P > 0.05), whereas the apparent digestibility of OM, total non-starch polysaccharide (NSP), non-cellulosic polysaccharide (NCP) and cellulose in the cecum of the infected pigs was higher than non-infected pigs (P < 0.05). The apparent colonic digestibility of ash and nitrogen was higher in non-infected pigs than in infected pigs (P < 0.05). The pigs fed the LF diet had a higher digestibility in all segment of the intestinal tract, whereas the HS diet had the lowest AID but higher or similar to the LF diet in the cecum, colon and the total tract (P < 0.05). The pigs fed the HF and HI diets, with high proportion of insoluble fiber, had a lower digestibility in the hindgut than the other two diets (P < 0.05). In conclusion, the infection with B. hyodysenteriae negatively influenced clinical signs of swine dysentery and growth performance but did not impair AID, and neither soluble or insoluble DF influenced the expression of the infection.

Growing pigs were given diets based on barley (whole or milled), which was either untreated or sprayed with an aqueous solution of sodium hydroxide (270 g sodium hydroxide per kg water) to give 33·8 g sodium hydroxide per kg dry matter. The barley grain was treated with sodium hydroxide while in the whole state. A total of 48 pigs penned individually were given the diets on a restricted scale of feeding from an initial weight of 31·6 kg until slaughter at 81·7 kg live weight. In a metabolism study, eight boars were subjected to the same experimental treatments in two identical 4 × 4 balanced change-over experiments.The diet containing untreated milled barley gave significantly faster live-weight gain and lower food conversion ratio than the other three diets (P < 0·001). Food conversion ratios were similar for untreated whole barley and sodium hydroxide-treated barley, whether this was whole or milled. Killingout proportion was similar for untreated and treated milled barley but was significantly lower when the diet contained untreated or treated whole barley.Milling significantly increased the digestibility of energy and nitrogen. Treatment with sodium hydroxide improved the digestibility of energy in the diet with whole barley but not in the diet with milled barley. With both whole and milled barley, treatment with sodium hydroxide increased the digestibility of crude fibre (P < 0·05) but with ground barley the digestibility and retention of nitrogen were reduced considerably by treatment with sodium hydroxide.It is concluded that treatment of barley with sodium hydroxide did not improve the nutritive value of either milled or whole grain, that it reduced the digestibility of nitrogen and that it severely depressed the utilization of digested energy for growth.
