Losses to Internal Parasites in Swine Production
Journal of Animal Science, 1988Experimental infections of pigs with Strongyloides ransomi, Stephanurus dentatus, Ascaris suum, Oesophagostomum spp. or Trichuris suis at increasing levels generally decrease daily gain and increase feed to gain ratio linearly. At lower, subclinical levels of infection, the feed to gain ratio typically is increased 3% to 6% by an infection.

Swine manure fermentation for hydrogen production
Bioresource Technology, 2009Biohydrogen fermentation using liquid swine manure as substrate supplemented with glucose was investigated in this project. Experiments were conducted using a semi-continuously-fed fermenter (8L in total volume and 4 L in working volume) with varying pHs from 4.7 through 5.9 under controlled temperature (35+/-1 degrees C). The hydraulic retention time (

Biotin in swine production: A review
Livestock Production Science, 1986Abstract Biotin, an essential water-soluble vitamin, is a cofactor of a number of enzyme systems responsible for carboxylation and transcarboxylation reactions. These reactions play a major role in the metabolism of carbohydrates and nucleic acids, in the synthesis of fatty acids, proteins and purines, and in the deamination of amino acids.
