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.

Amino acid digestibility in canola meal, 00-rapeseed meal, and 00-rapeseed expellers fed to growing pigs

Canola meal is produced from the rapeseed plant, a relative of broccoli and mustard. Rapeseed which has been hybridized to be low in both unpalatable glucosinolates and toxic erucic acid is called canola in Canada and the United States and 00-rapeseed in Europe. Oil can be removed from canola or 00-rapeseeds in two ways. Solvent extraction results in the production of canola meal or 00-rapeseed meal, while mechanical expelling results in the production of canola expellers or 00-rapeseed expellers. The meals and expellers have high concentrations of crude protein and amino acids, and can be used as protein sources in swine diets. An experiment was conductedto compare crude protein and amino digestibility between North American canola meal and European 00-rapeseed meal, and between 00-rapeseed meal and 00-rapeseed expellers.

Digestible and metabolizable energy concentration in 4 sources of canola meal and in soybean meal fed to growing pigs

Due to the increasing demand for protein for livestock feeding, the interest in using canola meal in diets fed to swine is increasing. Canola meal is a product of the rapeseed plant, an abundant oilseed crop grown in Canada, the Northern United States, and parts of Europe. Recently, new varieties of canola that contain more protein and less fiber than conventional canola have been selected. The de-oiled meals of these varieties have a concentration of crude protein that is close to that of de-hulled soybean meal.

It has been speculated that changes in the traditional pre-press solvent extraction oil removal procedure may improve the quality of canola meal. The traditional procedure involves use of heat to desolventise the de-oiled meal, but a new procedure allows for production of canola meal using a low-temperature procedure.

There is no information about the digestibility of energy in high protein canola meal. There also is no data comparing the digestibility of energy in canola meal processed at low temperatures versus high temperatures. Therefore, an experiment was conducted to compare the concentrations of digestible energy (DE) and metabolizable energy (ME) in high protein, high-temperature-processed, low-temperature-processed, and commercial canola meals, and to compare these values with the DE and ME in corn and soybean meal.

Amino acid digestibility in four sources of canola meal and soybean meal fed to growing pigs

Due to the increasing demand for protein for livestock feeding, the interest in using canola meal in diets fed to swine is increasing. Canola meal is a product of the rapeseed plant, an abundant oilseed crop grown in Canada, the Northern United States, and parts of Europe. The oil is extracted for use in cooking and agriculture, leaving a high-protein meal that can be used in livestock feeding. Although the concentration of protein and amino acids and the amino acid profile of canola meal is less desirable than that of soybean meal, its relatively low cost may make it an attractive option for producers. Recently, new varieties of canola that contain more protein and less fiber have been selected. The de-oiled meals of these varieties have a concentration of crude protein that is close to that of de-hulled soybean meal.  However, there is no information about the digestibility of amino acid in high protein canola meal when fed to pigs.

It has also been speculated that changes in the traditional pre-press solvent extraction oil removal procedure may improve the quality of canola meal. The traditional procedure involves use of heat to desolventise the de-oiled meal, but a new procedure allows for production of canola meal using a low-temperature procedure. There are, however, no comparative data between meals produced using the traditional high temperature procedure and meals produced using the low-temperature procedure.

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.
