    • Separation of feed mixtures and its effect on the production traits of growing-finishing pigs was studied in three experiments. In Experiments I and II the effects of different types of equipment to prevent separation in a silo were studied. Experiment III dealt with separation along a feed transport chain. Experiments I and II clearly demonstrated an increase in feed quality variation by filling a silo without any arrangement to reduce separation. The last feed to be extracted from a silo filled in this manner showed an increasing amount of small particles and contents of crude fibre and ash, a decrease in the bulk density and also in the digestibility of nutrients and in the performance of the pigs. Filling a silo equipped with chutes by an auger or pneumatically through a cyclone did not create separation problems, and consequently there were no differences between these treatments in the production experiments. Separation measured by particle size, bulk density or chemical composition was not noticeable along the feed transport chain (Experiment III). There was no effect on performance of the pigs of their location along the chain. © 1982.

  • A General Method for the Immobilization of Cells with Preserved Viability
  • 1983
  • Ingår i: Applied Microbiology and Biotechnology. ; 17, s. 319-326
  • Tidskriftsartikel (refereegranskat)abstract
    • Microbial, algal, plant and animal cells have been immobilized, with preserved viability, by entrapment in various matrices according to a new bead polymerization technique. The cell polymer/monomer mixture is kept suspended in a hydrophobic phase such as soy, paraffin, or silicon oil, tri-n-butylphosphate, or dibutyphtalate, which is compatible with the cells. The various monomers or polymers tested include agarose, agar, carrageenan, alginate, fibrin, and polyacrylamide. Furthermore, by adjustment of the stirring speed of the suspension, beads of desired diameter can easily be obtained. The entrapped cells are fully viable and biosynthetically active.
