Streptococcus (S.) suis translocates across the intestinal barrier of piglets after intraintestinal application. Based on these findings, an oro-gastrointestinal infection route has been proposed. Thus, the objective of this study was to investigate the survival of S. suis in the porcine stomach. Whereas surviving bacteria of S. suis serotypes 2 and 9 were(More)
The physical form of the diet plays an important role for morphological adaptations of organs in the gastrointestinal tract. It was hypothesized that different physical forms of one diet could exert extra-enteric effects, under local and systemic neuroendocrine regulation. Gross morphology, fresh mass and cytoarchitecture of mandibular glands (MG) were(More)
Sixty weaned piglets (33 d, 7.96 ± 1.09 kg BW) were divided into 4 groups with 15 pigs each and fed identical diets in which meal was coarsely ground (CM), coarsely ground and pelleted (CP), finely ground and pelleted (FP), or coarsely ground and extruded (CE) for 4 wk. At the end of the trial the pigs were killed and samples of the digesta were taken from(More)
The physical form of diets has a marked impact on the development of gastric ulcers in pigs. Earlier studies showed effects of fine grinding and pelleting on the integrity of gastric mucosa as well as on local intragastric milieu. This study was conducted to evaluate the effects of dry or liquid feeding on intragastric milieu (DM and pH) in pigs. The 23(More)
The hypothesis of this study was that feeding a fine, pelleted diet (FP) compared to a coarse meal diet (CM) results in a higher mannose content in the intestinal mucus of pigs and therefore an increased in vitro adhesion of Salmonella Typhimurium DT104 L to the mucus. The 2 diets were fed to a total of 24 weaned pigs for 6 wk after which mannose content in(More)
To prove the hypothesis that the physical form of diet affects the outcome of an artificial infection with Salmonella Enteritidis in broilers, 7-day-old birds were allotted to one of four groups and fed botanically, and nearly also chemically identical diets, differing in grinding and further compaction. In total, two birds from each group (age 14 days)(More)
