Expeller-Pressed Canola Meal in Poultry Feeds
Dual Protein and Energy Feed Ingredient
Pacific Coast Canola canola meal is produced by a mechanical expeller-pressing process. Different from the conventional pre-press, solvent-extraction processing of canola meal, hexane solvent is not used to extract the oil in the expeller-pressing process. The resulting meal is solvent free and contains higher levels of oil (approximately 11 percent) compared to conventional solvent extracted canola meal (approximately 3 percent). Despite its higher oil content, the protein content in Pacific Coast Canola expeller-pressed canola meal is not diluted; it has the same amount of protein as conventional canola meal. This is because the moisture content of Pacific Coast Canola canola meal is only 5 percent, versus 12 percent for conventional canola meal.
Excellent Amino Acid Balance
Canola meal is known for its excellent amino acid balance, with especially high levels of methionine and cystine. This is important for feeding poultry, due to their high sulfur amino acid requirements for feather growth. Pacific Coast Canola canola meal has the same amino acid balance as canola meal, with a slightly higher amino acid digestibility. Pacific Coast Canola canola meal does not undergo the same toasting that conventional canola meal undergoes, since no solvents are used, and no steam sparging of solvent is required.
High Oil and High Essential Fatty Acids
Pacific Coast Canola canola meal contains high levels of essential fatty acids, especially linoleic acid and linolenic acid. This means that adding linoleic acid (in the form of extra oil) is not usually required when using Pacific Coast Canola canola meal. Its high oil content gives it one of the highest energy contents of all feed protein ingredients.
Can Be Used at High Inclusion Levels in All Poultry Feeds
Like conventional canola meal, Pacific Coast Canola meal contains low levels of glucosinolates, which means it can be used at high inclusion levels in broiler chicken, egg layer and turkey feeds. Also, the high energy content of Pacific Coast Canola meal, due to its high oil and high dry-matter contents, means that it will work economically in higher energy feeds, such as broiler feeds.
