Salmonella typhimurium colonization, pH, and density of ceca were measured in 3-, 5-, and 6-wk-old broilers fed either a control ration or rations with added fructooligosaccharides (FOS) or lactose derivatives (LD). The purpose was to compare dietary crude FOS from Jerusalem artichokes with refined FOS and two LD for ability to reduce Salmonella colonization as determined by semi-quantitative p...

Even after a full century, Hilbert's problems have never been thoroughly tested. Who has ever chatted with a telemarketer about the Riemann hypothesis or discussed general reciprocity laws with the family physician?...

Preservation methods were evaluated forjerusalem artichokes (Helianthus tuberosus L.) to facilitate the back-up of field collections. In vitro plant cultures were established from field-harvested tubers for nine jerusalem artichoke cultivars obtained from the Plant Gene Resources of Canada, Saskatoon Research Center, Saskatoon, Canada. Most cultivars could be maintained at 5 °C or under 25°C gr...

Food miles are the distance food travels from where it is grown to where it is ultimately purchased or consumed by the end user. The term food miles has become part of the vernacular among food system professionals when describing the farm to consumer pathways of food. A Weighted Average Source Distance (WASD) can be used to calculate food miles by combining information on the distances from pr...
