As the world’s second largest exporter of canola seed, Australia’s exports consistently exceed one million tonnes. Our canola crop has grown to a size and quality that meets the high expectations of exporters, domestic crushers and intensive livestock producers.
From a minor crop in the late 1980s, canola is now Australia’s third largest broad-acre crop (after wheat and barley) – canola is widely grown across south-east Australia and in western Australia. Australian growers have adapted to their unique climate and growing conditions, which vary over large areas.
Canola meal is a high quality protein meal suitable for most livestock diets. The livestock sector, and its consequent usage of feedstuffs, is growing rapidly, with higher demand for oilseed meals. Currently, a large share of this is met by imported soymeal but as we have increased our production of canola and cottonseed, domestically-produced meals have also been in greater use. Canola meal represents around one quarter of the total meal market in Australia, and is mainly used in pig, poultry and dairy rations.

The seed is typically trucked to the nearest crushing plant, where oil is extracted and meal is processed.

 
Step 1: First the seed is rolled or flaked. This ruptures cells and makes the oil easier to extract.

Step 2: Next the flaked or rolled seeds are cooked and subjected to a mild pressing process that removes some of the oil and compresses the                                     seeds into large chunks called “cake fragments.”

Step 3: The cake fragments undergo further processing to remove most of the remaining oil. Pre-press solvent extracting is the most common                                 method.

Step 4: The oil and meal are then processed separately, according to the end product requirements. Different treatments are used to process                                   salad oils, margarines and shortenings. The meal may be processed into pellets or mash.

Canola meal, or rapeseed meal, is a by-product of the oil extraction of canola. The meal is produced by the solvent extraction process along with the oil. The processing method will influence the nutrient availability, the anti-nutritional factors (toxins) and thus the nutritive value of the meal. Solvent extracted canola meal is processed at lower temperatures to produce a high quality meal with low levels of the anti-nutritional factors.
Canola meal can also be produced by the less common techniques of cold pressing and expeller extraction. There are some differences in the processes, which affect the nutritive value of the resulting meal. Cold pressed meal may contain higher levels of toxins, which will limit its inclusion into feeds.

The following information is in regard to solvent extracted meal:

Directions for use
Solvent extracted canola meal can be included in the diets ofpigs, poultry, cattle, sheep and horses as part of a balanced diet.
Due to the risk of harmful anti-nutritional factors, it is important to check on the processing method of the meal.
Higher levels of inclusion in pig feeds, up to 20% have been associated in some cases with ‘off-flavours’ in the pig carcass. Higher levels of inclusion in layer hen feeds has been associated with fishy taint in eggs.
Recommendations of up to 5% have been suggested for the inclusion of canola meal in the diets for breeding animals.

Deleterious substances
The problems associated with the feeding of canola meal to pigs and poultry are due to the presence of a number of potentially toxic substances: erucic acid, glucosinolates, sinapine and tannins.
Due to the risk of anti-nutritional factors, it is preferable to use canola meal that has been produced by solvent extraction or expeller pressed processes.
Provided canola meal has been properly processed the presence of glucosinolates is no longer a major limiting factor. However the level of tannins, about 3% in canola meal, may reduce the digestibility of dietary protein.
Sinapine, which is found in canola meal at a level of 1.0% to 1.25%, may reduce the palatability of rations and result in off-flavoured eggs.
