“…However, coliform bacteria proliferated in the FLF (Table 1). Other investigations have shown that coliform bacteria are suppressed in FLF Russel et al, 1996;Mikkelsen and Jensen, 1997). The presence of coliform bacteria in the FLF may be an explanation for the relatively poorer growth performance of piglets fed the FLF in the present study (Table 2).…”

ASBSTRACTFeeding fermented liquid feed (FLF), containing high numbers of lactobacilli and yeast, and high concentrations of lactic acid, to piglets at weaning did not improve growth performance compared with piglets fed non-fermented liquid feed (NLF). No significant changes in the microbial activity (ATP concentration) in the GI tract of piglets fed the FLF were observed. However, pH in the stomach was significantly reduced, and a different microbial fermentation pattern in the colon was observed. Furthermore, the density of yeast was significantly increased, whereas the density of coliform bacteria was significantly decreased throughout the GI tract in piglets fed the FLF. The results suggest, that feeding FLF to piglets at weaning may assist in the prevention of coliform scours.

“…Lactobacillus spp. have been found to proliferate rapidly during the first days of the fermentation of pig feed, after which fairly constant numbers are maintained (10,12,20,28). However, identifying yeasts and LAB to the species level demonstrated substantial changes within these apparently stable populations.…”

The diversity of populations of yeast and lactic acid bacteria (LAB) in pig feeds fermented at 10, 15, or 20°C was characterized by rRNA gene sequencing of isolates. The feeds consisted of a cereal grain mix blended with wet wheat distillers' grains (WWDG feed), whey (W feed), or tap water (WAT feed). Fermentation proceeded for 5 days without disturbance, followed by 14 days of daily simulated feed outtakes, in which 80% of the contents were replaced with fresh feed mixtures. In WWDG feed, Pichia galeiformis became the dominant yeast species, independent of the fermentation temperature and feed change. The LAB population was dominated by Pediococcus pentosaceus at the start of the fermentation period. After 3 days, the Lactobacillus plantarum population started to increase in feeds at all temperatures. The diversity of LAB increased after the addition of fresh feed components. In W feed, Kluyveromyces marxianus dominated, but after the feed change, the population diversity increased. With increasing fermentation temperatures, there was a shift toward Pichia membranifaciens as the dominant species. L. plantarum was the most prevalent LAB in W feed. The WAT feed had a diverse microbial flora, and the yeast population changed throughout the whole fermentation period. Pichia anomala was the most prevalent yeast species, with increasing occurrence at higher fermentation temperatures. Pediococcus pentosaceus was the most prevalent LAB, but after the feed change, L. plantarum started to proliferate. The present study demonstrates that the species composition in fermented pig feed may vary considerably, even if viable cell counts indicate stable microbial populations.

“…In this way, piglets had almost no advantage of consuming the diet as FLF, as mostly the supernatant water part, especially in the beginning of the experiment, was consumed (Figure 2). The trough design is one of the possible reasons for the worse performance of the piglets on FLF (Russell et al 1996). More feed wastage was noted by piglets fed FLF compared with piglets fed a dry diet.…”

ABSTRACT:In two experiments with weaned piglets, the effects of fermented liquid feed (FLF) (produced with probiotic strain Pediococcus acidilactici, Bactocell ® , Lallemand S.A.S.) on performance and some bacteriological and morpho-histological parameters of the gut were investigated, and the impact of sedimentation of the solids in the FLF thereon. In experiment I, FLF or the same dry feed (DRY) was offered ad libitum for 28 days to two groups of 15 weaned piglets (28 days of age) each (3 replicates of 5 pigs). Performance was negatively affected by feeding FLF and concomitant with that the group fed the FLF diet showed shorter villi (501 vs 550 µm) and smaller crypts (264 vs 289 µm) in the small intestine at 3 m proximal to the caecum (P < 0.05). It was assumed that these poorer results were due to sedimentation of the solids in the FLF and therefore a second experiment was conducted with sepiolite (10 g/kg) added to the feeds. Sepiolite tends to slow down the segregation of particles in slurry. The three feeding groups (weaned piglets, 27 days of age) in this experiment were DRY, DRY with probiotic (DRY+), and FLF. The group fed FLF (body weight gain (BWG) 254 g/piglet/day; feed : gain ratio 1.38) did now perform better (P < 0.05) than the groups fed the DRY (BWG 184 g/piglet/day; feed : gain ratio 1.52) and DRY+ (BWG 185 g/piglet/day; feed : gain ratio 1.48) diets, which did not differ. Villus length in the small intestine at 3 m proximal to the caecum was also higher for the group fed FLF (558 µm) compared with the group fed the DRY+ diet (490 µm; P < 0.05). It was concluded that feeding FLF is beneficial to freshly weaned piglets on condition that sedimentation of the solids in the feed slurry can be controlled.
