Abstract The objective was to determine the influence of feed intake (FI) and fiber source on the apparent total tract digestibility (ATTD) of gross energy (GE) and nutrients in pigs. Twelve barrows with an initial body weight (BW) of 34.0 ± 2.6 kg were allotted to a replicated 6 × 4 Latin square design with 6 treatments and 4 periods. The 6 treatments were consisted of a 2 × 3 factorial arrangement with 2 amounts of FI (9.0 and 4.5% × BW0.75) and 3 dietary fiber sources. Three diets were 1) a corn-soybean meal-based basal diet (BD), 2) a diet replacing 30% of corn and soybean meal in BD with sugar beet pulp (SBP) as a source of soluble dietary fiber (SDF), and 3) a diet replacing 15% of corn and soybean meal in BD with corn cobs as a source of insoluble dietary fiber (IDF) to obtain a similar IDF concentration as in the SBP diet. Following a 6-d adaptation, feces were collected for 5 d. The ATTD of GE, dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in diets was greater (P < 0.05) for pigs fed at 4.5% of BW0.75 compared with those fed at 9.0% of BW0.75. The ATTD of GE, DM, OM, NDF, and ADF in SBP diet was greater (P < 0.01) than that in corn cob diet. However, there was no interaction between FI and fiber source on energy and nutrient digestibility. The ATTD of GE, DM, OM, protein, NDF, and ADF in SBP was greater (P < 0.01) than that in corn cobs. In conclusion, energy and nutrient digestibility values were increased by reduced feed intake and were greater in sugar beet pulp than in corn cobs without interaction between feed intake and fiber source.

Broiler chickens were fed on a control diet based on maize or a diet containing sugar-beet-pulp fibre (Beeffiber) at an inclusion level of 46 g/kg. Diets were providedad lib. or at a restricted level either once daily or three times daily. On days 13 and 20, chickens fed on thead lib. control and sugar-beet-pulp-containing diets generally weighed more and had poorer feed conversion ratios than chickens given the restricted control and sugar-beet-pulp-containing diets respectively. Furthermore, chickens given the restricted diets once daily had greater body weights and generally improved feed conversion efficiencies compared with chickens given the restricted diets three times daily. Generally, elevated plasma Lipid concentrations were observed amongst chickens given the restricted diets once daily compared with chickens fedad lib. as well as the restricted diets three times daily, while chickens fed on restricted diets three times daily had plasma lipid concentrations intermediate between those fedad lib. and once daily. In a plasma triacylglycerol response study on day 22, feeding of sugar-beet-pulp-containing diets generally reduced postprandial triacylglycerol concentrations and delayed triacylglycerol response relative to chickens given the control diets eitherad lib. or restricted, which may indicate gastrointestinal adaptation to feeding of a fibre-rich diet. Postprandial triacylglycerol concentrations observed for chickens receiving restricted diets were increased compared with chickens given the respectivead lib. diets, indicating adaptation of chickens to reduced feed frequency. On day 25, feeding of sugar-beet-pulp-containing diets decreased digesta dry matter content and ileal organic matter digestibility. Chickens given sugar-beet-pulp-containing diets generally had, on day 25, increased caecal short-chain fatty acid (SCFA) concentrations in comparison with chickens given thead lib. control diet, indicating increased fermentation of dietary components. It is also noteworthy that the greatest SCFA concentrations were observed amongst chickens given the control diet once daily, suggesting enhanced caecal fermentation capacity. This may have been a consequence of increased bacterial activity and caecal hypertrophy due to infrequent feeding of a low-fibre diet.

Linseed (Linum usitatissimum) and its by-products are common supplements used in equine diets and are claimed to have beneficial health effects. In this study, the effect of linseed groat-based fibrous feed supplements on diet digestibility was studied. Also, possible detrimental health effects due to continuous feeding of supplemental feeds containing linseed were examined by evaluating blood parameters. The experimental design was arranged as two balanced 3 × 3 Latin Squares. The horses were individually fed at the maintenance energy level, the forage-to-concentrate ratio being 70:30, with three diets: (A) Control diet consisting of dried hay and whole oats; (B) Control diet + Feed 1; and (C) Control diet + Feed 2. Feed 1 contained 70% of linseed groats, 15% dried carrot, 10% dried garlic and 5% molasses. Feed 2 contained 65% linseed groats, 15% molassed sugar-beet pulp, 10% dried garlic, 5% dried carrot and 5% molasses. Digestibility data were obtained by using chromium mordanted straw as an indigestible external marker for the estimation of apparent digestibility. Blood samples were collected from the jugular vein at the end of each feeding period to evaluate the possible effects of the supplemented diets B and C on the health of the horses. Diets B and C had a higher digestibility of crude protein compared to the control diet A (p < 0.05). In addition, the digestibility of ether extract was higher in the supplemented diets than in the basal feeding (p < 0.01). There were no statistically significant differences or trends (p > 0.05) in the blood parameters between the treatments. It is concluded that linseed groat-based supplements (offering approximately 6.3%–6.7% linseed groats in the diet’s dry matter (DM), or 0.8 g/kg BW/d), and feed containing soluble fibre sources (sugar-beet pulp, dehydrated carrot), improved the crude protein and fat digestibility of hay-oats diets of horses, and can be used, for example, in feeding strategies replacing grains in the horse rations in order to reduce the intake of starch without any adverse effects on the blood parameters and health of the horses.

The aim of this study was to examine if enzyme supplementation could improve the performance of early weaned piglets by increasing nutrient digestibility of diets in which energy content was reduced by replacing wheat with barley or sugar beet pulp.The following diets were supplemented with (+) and without (-) stabilised multi-enzyme premixes (E1, E2 and E3 respectively): diet W containing 706g/kg wheat and formulated to supply 14 MJ DE/kg, diets B and SBP in which DE was reduced to 13.25 MJ/kg by completely replacing wheat with barley or 185g/kg sugar beet pulp respectively. All diets were formulated to provide 150g/kg of apparent ileally digestible ideal protein, giving a crude protein concentration of about 217g/kg. Soya bean (200g/kg) and fish meal (75g/kg) were added at equal levels to all diets. Main enzyme activities in E1 were xylanase (T . longibrachiatum), amylase (B. subtilis) and pectinase (A. niger), in E2 beta-glucanase (T. longibrachiatum), xylanase (T. longibrachiatum) and amylase (B.subtilis) and in E3 beta-glucanase (T. longibrachiatum), amylase (B. subtilis) and pectinase (A. niger). The feeds were pelleted (3mm).
