High protein canola meal

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.

Performance and carcass characteristics of growing and finishing pigs fed diets containing high protein or conventional canola meal

Canola meal can be used as a source of protein in swine diets, but conventional canola meal contains less protein than soybean meal. In recent years, new varieties of canola have been developed with seeds that contain more protein and less fiber than conventional canola seeds. The meal from these new varieties of canola has a protein content similar to that of soybean meal.

Previous research at the University of Illinois demonstrated that diets containing at least 30% high protein canola meal (CM-HP) or conventional canola meal (CM-CV) could be fed to nursery pigs without reducing growth performance. It has not yet been determined how much soybean meal can be replaced by conventional or high protein canola meal in diets for growing-finishing pigs without affecting growth performance or carcass characteristics. Therefore, an experiment was performed to determine the optimum inclusion rate of high-protein and conventional meal in diets fed to growing and finishing pigs.

Effects of including conventional or high protein canola meals in diets for nursery pigs

Canola meal is a by-product of the canola oil industry. Conventional canola meal contains about 37% crude protein, and is a good protein source for swine diets. New varieties of canola with seeds that contain less fiber and more protein than conventional canola seeds have been hybridized. The meals produced from these new hybrids have a crude protein content similar to that of dehulled soybean meal (Table 1). No data exist on how feeding these high protein canola meals to weanling pigs affects growth performance. Inclusion levels also have not been established for the use of these products in nursery diets.

An experiment was conducted to determine the effect on growth performance of including conventional or high protein canola meals at different levels in diets fed to weanling pigs.

Concentration of digestible and metabolizable energy and digestibility of energy in high protein canola meal, conventional canola meal, and soybean meal fed to growing pigs

Canola meal is the defatted meal that remains after oil has been extracted from the seeds of the rapeseed plant, Brassica napus.  Canola meal is high in crude protein and amino acids relative to most plant protein sources, and the amino acids in canola meal are well digested by pigs. However, it is also relatively high in fiber, which reduces energy digestibility and digestible energy concentration. New varieties of Brassica napus with a thinner seed coat have been hybridized, which contain less fiber and more protein than conventional rapeseed. The meal produced from these varieties is known as high protein canola meal. No data exist for the digestibility of energy in this source of high protein canola mealwhen fed to pigs. Therefore, an experiment was conducted to determine the apparent total tract digestibility (ATTD) of energy and the concentrations of digestible and metabolizable energy in two sources of high protein canola meal (CM-HP1 and CM-HP2) fed to growing pigs, and to compare these values with values for conventional canola meal (CM-CV) and soybean meal (SBM).
