Canola meal

The contribution of digestible and metabolizable energy from high fiber dietary ingredients is not affected by inclusion rate in mixed diets fed to growing pigs

Fiber in feed ingredients used in diets for pigs is mainly used for energy, which is synthesized by microbes in the hindgut of the pig and absorbed in the form of short chained fatty acids. To estimate the energy that a pig can obtain in a particular fibrous ingredient, a digestibility experiment is usually conducted and the digestible energy (DE) and the metabolizable energy (ME) in the ingredient is determined. However, it is not known if the obtained DE and ME values are accurate for all inclusion rates of the feed ingredient in diets.

There are two reasons that differing inclusion rates of high fiber ingredients in diets fed to pigs might result in variable DE and ME values. Because energy from dietary fiber is obtained via hindgut fermentation, there may be a saturation point in the fermentation capacity in the hindgut of growing pigs. In addition, increasing dietary fiber increases the passage rate of feed through the digestive tract and thus reduces time for fermentation. However, it is not known if these potential issues affect the DE and ME in fibrous ingredients fed to pigs. An experiment was conducted to determine effects of inclusion rate of four commonly used high fiber dietary ingredients on the concentration of DE and ME by growing pigs.

Productivity of sows fed diets containing canola meal produced from high protein or conventional varieties of canola seeds during gestation and lactation

Canola meal is second only to soybean meal as a protein source used in animal diets. However, the digestibility of amino acids and digestible energy is lower in canola meal than in soybean meal because of the high concentration of fiber in canola meal. The high fiber content and the presence of glucosinolates limit inclusion of canola meal in diets fed to pigs.

Research on using canola meal in pig diets at different stages has indicated that it can be used in gestation diets without limitation and 15 to 20% may be included in lactation diets. However, at least one study indicated that including canola meal in gestating and lactation diets reduced the number of pigs born alive and the number of pigs weaned, and also reduced lactation feed intake and litter weaning weight.

New canola varieties have been developed that yield meal with more protein and less fiber compared with conventional canola meal (CM-CV). The objectives of this research were to determine the effects of feeding diets containing high protein canola meal (CM-HP) or CM-CV to sows during gestation and lactation, and to determine the optimum inclusion rates of CM-HP and CM-CV in gestation and lactation diets.
