“…3) is also in agreement with literature (Salvador et al, 1993). These authors reported that the nature and generation of SCFA were closely related to the major sugars available, and concluded that uronic acids seemed principally involved in the production of acetic acid, whereas propionic acid could be promoted by the fermentation of glucose and, in a lesser extent, of xylose and arabinose.…”

“…The differences observed in the metabolism of the OS components was in agreement with the results reported in related studies. In OS mixtures, the structural units and their arrangement control the rate and extent of degradation, as well as the nature of the SCFA produced (Salvador et al, 1993).…”

“…High proportions of acetic acid in the feces of piglets receiving sugar beet pulp were expected (Salvador et al, 1993;Sunvold et al, 1995;Bauer et al, 2001). However, for increasing ages the differences between treatments in the fecal moisture and VFA fecal contents gradually disappeared.…”

The effects on growth performance and on some health parameters due to the inclusion of sugar beet pulp in antibioticfree diets for weaned piglets were evaluated on a commercial farm. A conventional diet (C) and one containing 120 g/kg of sugar beet pulp (SBP) were fed to 668 weaned piglets from 21 to 64±3 days of age. Every two weeks, live weight and feed consumption (FC) of the two groups were recorded by pens. Fecal samples were collected from 8 pairs of piglets for each treatment to evaluate the evolution over the time of the apparent digestibility of the nutrients, as well as the volatile fatty acids content and the microbial count in the feces. The dietary treatment did not affect FC. In comparison to C, SBP slightly reduced average daily gain over 36 to 49 (528 vs. 498 g/d; P<0.05) and 50 to 64±3 (677 vs. 631 g/d, respectively; P<0.01) days of age. Digestibility of NDF of diet C increased with age from 441 to 526 g/kg whereas that of diet SBP increased from 465 to 638 g/kg. The differences between diets became significant after 36 days of age (P<0.01). From 29 to 35 days of age higher contents of water (793 vs. 713 g/kg; P<0.01), acetic (322 vs. 206 µmol/g dm; P<0.01) propionic (108 vs. 81 µmol/kg dm; P<0.01) acids and lower counts for fecal-coliforms (6.9 vs. 8.2 log 10 /g; P<0.01), clostridia (1.3 vs. 2.3 log 10 /g; P<0.01) and Staphylococcus spp. (6.7 vs. 8.1 log 10 /g; P<0.01) were found in the feces of the SBP piglets compared to those of C. These differences progressively disappeared with time. Some piglets showed clinical signs of purulent arthritis and meningitis, but no signs of diarrhea were observed. The SBP group showed, with respect to C, a significantly lower number of piglet deaths caused by meningitis (15 vs. 30 ‰, respectively; χ 2 , P<0.05), and a significantly lower number of piglets removed because lack of growth (33 vs. 76 ‰, respectively; χ 2 , P<0.01). No clear evidence to explain this result was found, however it was concluded that the inclusion of 12% of sugar beet pulp in antibiotic-free diets can improve the health status of piglets with little effect on growth performance.

“…However, the degradation of feedstuffs in the rumen requires sequential processes of solubilization and fermentation. Both processes depend on the chemical composition and structure of the substrate (Salvador et al 1993;Merchen & Bourquin, 1994). Solubilization of cell walls requires hydration, colonization by rumen micro-organisms and then the release of enzymes from these micro-organisms, to digest the complex cell-wall structures (McAllister et al 1994).…”

The use of cumulative gas and volatile fatty acid production to predict in vitro fermentation kinetics of Italian ryegrass leaf cell walls and contents at various time intervals

et al. 1998

Differences between the fermentation characteristics of cell contents (CC) and protease-treated cell walls (CW) of young leaves of Italian ryegrass (Loliurn rnultgorurn Lam.) cultivar Multimo (tetraploid), were studied in vitro. Gas and volatile fatty acid (VFA) production rates were measured at regular intervals, as was the degradability of organic matter (OM) of CW. The measured VFA were used to predict the gas production and fermentable OM using stoichiometric calculations. For CW the volume and kinetics of measured gas production were the same as those predicted from the VFA formed. In contrast, the measured gas production for CC was consistently less than predicted, indicating that the stoichiometric equations were not valid for rapidly fermenting substrates. For both CC and CW, the relative rate of acetic acid production levelled off more slowly than for other VFA, resulting in an increasing gas yield (in ml/g fermentable OM) after 12 (CW)-24 (CC) h incubation. Consequently, the fermentation of OM was not linearly related to gas production kinetics. For CW, the kinetics of decline of degradable OM and fermentable OM were the same, after correction for a constant 'lost fraction' of degradable OM of 205 g/kg OM. This work indicates the value of detailed studies of fermentation processes to evaluate herbage quality. In particular, the role of CC and the difference between degradation and fermentation require further attention.
