Condensed tannins (CT) have been observed to reduce enteric CH4 production when added ruminant diets. However, high concentrations of CT in forages such as sericea lespedeza (SL; Lespedeza cuneata (Dum. Cours.) G. Don) may depress nutrient digestibility. Oilseed crops, lipid concentration, also via toxicity methanogenic bacteria with less depression it is unclear whether combining these two fee...

Aflatoxins are naturally occurring toxins produced by certain fungi: mainly Aspergillus flavus and Aspergillus parasiticus. Several types of aflatoxins (B1, B2, G1, and G2) are produced by these fungi. The B1 form is recognized by the International Agency for Research on Cancer as one of the most naturally occurring toxic and carcinogenic substances found in nature. 1 These aflatoxin-producing ...

In most countries general legislation on food (and feed) prohibits the sale of products containing poisonous or harmful substances, which would include relevant mycotoxins as well. So far only aflatoxin has been dealt with specifically in legislation. The aflatoxin control may include all foods (and feeds) but is limited in most countries to certain commodities likely to be heavily contaminated...

As part of a project on adding value to farm operations with food-grade oils, the University of Vermont Extension and Pennsylvania State Extension teamed up to evaluate the design and operation of several small -scale oilseed presses. While there is a great deal of interest in the production of oilseeds, many questions arise about post-harvesting processing, and many of these concerns revolve a...

Microsomal membrane preparations from Mortierella alpina catalysed the conversion of sn-glycerol 3-phosphate and [(14)C]oleoyl-CoA to radioactive phosphatidic acid, diacylglycerol and triacylglycerol. Experiments with lysophosphatidic acid and [(14)C]oleoyl-CoA gave a similar pattern of radioactivity in the complex lipids. The specific activity of lysophosphatidate acyltransferase was almost ei...
