Canola Meal

canola-mealCanola Meal for Beef, Dairy Cattle and Lamb Use

Canola meal is the major protein meal used within the Australian livestock industries, this being due to the demand for canola oil and the production of meal through the oilseed crushing process. The Australian market has two differing oilseed crushing processes in the form of expeller or solvent extraction plants.
The minimum protein content of canola meal varies with the protein level of the seed being crushed. Canola seed protein levels are affected by seasonal growing conditions, with drier seasons tending to result in higher protein seed and resulting meal. The range in protein levels shown occur between different crushing years and Riverland Oilseed are able to confirm actual protein levels for delivery periods.
Canola seed contains over 40% oil and the crushing process aims at maximise oil extraction. Through expeller processing, after initial seed heating, oil is removed through mechanical processing. The resulting finished meal has residual oil which from Riverland Oilseed processing plants is in the range 9-11%. For canola processed through the Riverland Numurkah solvent extraction plant, an additional oil extraction process is applied which results in the finished meal containing 2-3% oil. The higher residual oil within expeller meal results in lower levels of protein, fibre and minerals, whilst energy content is significantly increased.
Whole canola seed is processed, thus the seed coat contributes to the fibre contained within canola meal.
Canola meal is an ingredient that supplies energy from sugars, starch and oil for ruminant feeding whilst at the same time providing additional ADF and NDF.

Canola Meal Use in Beef Feedlot Rations
 
Canola meal is accepted globally as a valuable raw material for use within cattle feeding. It is primarily used a source of rumen degradable and undegradable protein. The rumen degradable protein fraction within canola meal is released gradually in line with microbial fermentation.
Unlike urea, a source of non protein nitrogen, which is very soluble and rapidly released within the rumen, canola meal provides a source of nitrogen within the rumen which better matches microbial growth.
The undegraded or bypass protein component of canolameal supplies essential amino acids for absorption within the small intestine. Canola meal is an ideal raw material for use in younger stock where higher protein requirements need to be met or where low protein grains and roughage sources are in use.
Canola meal relative to cereal grains, provides a source of energy in the form of sugars and residual oil which is not fermented as quickly within the rumen. This assists in stabilising rumen fermentation and lessens the acid load within the rumen and potential rumen pH depression.
Where expeller canola meal is used, the residual oil content provides a significant advantage in terms of supplying energy.
This oil also provides additional benefits in terms of coat condition and gloss within cattle fed for show or sale purposes.
Canola meal has been demonstrated to be consumed in preference by cattle, thus shy feeders and cattle unaccustomed to grain feeding can be introduced more successfully when canola meal is included within the feeding ration.

Canola Meal Use in Lamb Feedlot Rations
(High protein requirement)
Because the growth of young lambs is mostly lean muscle (protein) rather than fat, protein supply is critical. As lambs get older, they deposit more fat, thus their requirement for protein diminishes. Lamb protein requirements are also higher with higher energy rations typically used for feedlot use. With a high energy ration and lightweight lambs, the protein requirement is 18-19%.
 
Canola Meal Use in Dairy Rations
Canola meal is accepted globally as a valuable raw material for use within dairy cattle feeding. It is primarily used as a source of rumen degradable and undegradable protein. The rumen degradable protein fraction within canola meal is released gradually in line with microbial fermentation. Unlike urea, a source of non protein nitrogen, which is very soluble and rapidly released within the rumen, canola meal provides a source of nitrogen within the rumen which better matches microbial growth.
The undegraded or bypass protein component of canola meal supplies essential amino acids for absorption within the small intestine. Canola meal is an ideal raw material for use in high production dairy herds where higher protein requirements need to be met or where low protein grains and roughage sources are in use.
Canola meal relative to cereal grains, provides a source of energy in the form of sugars and residual oil which is not fermented as quickly within the rumen. This assists in stabilising rumen fermentation and lessens the acid load within the rumen and potential rumen pH depression. Where expeller canola meal is used, the residual oil content provides a significant advantage in terms of supplying energy.
