Research Report

Evaluation of the nutritional value of sources of canola meal fed to pigs

Canola meal is produced from the rapeseed plant, a relative of broccoli and mustard. Natural rapeseed contains glucosinolates, which make feed unpalatable, and erucic acid, which is toxic to animals. These anti-nutritional factors are heat-stable, and therefore, cannot be removed by heat-treating rapeseed. Rapeseed, which is low in both glucosinolates and erucic acid, has been produced by hybridization, and is called canola in Canada and the United States and 00-rapeseed in Europe. Oil can be removed from canola and rapeseeds via solvent extraction or mechanically expelling. The solvent extraction process results in production of canola meal or 00-rapeseed meal and mechanical expelling of oil results in production of canola expellers or 00-rapeseed expellers.

The objective of this study was to compare the chemical compositions of canola meal from North America and 00-rapeseed meal from Europe and to compare the composition of 00-rapeseed meal and 00-rapeseed expellers.  Ten samples of canola meal were collected from crushing plants in North America, and eleven samples of 00-rapeseed meal and five samples of 00-rapeseed expellers were collected from crushing plants in Europe. The samples were analyzed for energy, fat, sugar, starch, fiber, crude protein, amino acids, and minerals.

Podcast

March 29: Energy concentration and amino acid digestibility of high protein, low oligosaccharide, and conventional full fat soybeans fed to growing pigs

Jin Yoon, master's student in the Stein Monogastric Nutrition Lab, presents the results of two experiments to determine the energy concentration and amino acid digestibility of high protein and low oligosaccharide soybean varieties, and to compare them to conventional soybeans. Adapted from a presentation at the 2012 ADSA-ASAS Midwest Sectional Meeting, Des Moines, IA, March 19-21 2011.
