Soybean meal is the protein reference of the world feed market: every other protein source is priced against it, and every compound feed formulation starts from what it would cost to buy the same amino acid contribution from soy. What trades is the defatted, toasted residue of the crush, sold on protein content and on two process indicators that tell the buyer whether the toasting was right. Ukraine crushes a significant soybean crop and supplies both the domestic feed industry and export markets, with the additional commercial feature that a large part of the Ukrainian crop is non-genetically-modified, which matters to European buyers serving GM-free labelled milk, egg and meat programmes. For a feed buyer the meal is a straightforward article to specify and an easy one to get wrong, because the two parameters that decide nutritional value are not protein and fat but urease activity and protein solubility.
Grades, cuts and calibration
Protein is the headline grade and it is quoted in bands: high protein meal in the region of 47 to 48 per cent from dehulled beans, and standard meal around 44 to 46 per cent with the hulls returned. The critical contractual point is the basis. A protein figure can be quoted as-is, on a dry matter basis, or on a protein-plus-fat combined basis, and the three are not the same number; contracts in the trade typically specify protein plus fat on a stated moisture, and a buyer comparing two offers quoted on different bases is comparing nothing. The second grading axis is the toasting indicators, and these are what actually separate good meal from bad. Raw soybean contains trypsin inhibitors and other antinutritional factors that must be destroyed by heat, but excessive heat destroys lysine by Maillard reaction. Urease activity, expressed as the rise in pH or as milligrams of nitrogen per gram per minute, detects undertoasting; a common trade ceiling is around 0.3 mg N per gram per minute. Protein solubility in potassium hydroxide, usually specified in a window of roughly 73 to 85 per cent, detects overtoasting at the bottom of the range and undertoasting at the top. A meal that satisfies both is correctly cooked. A meal that passes on protein and fails on either indicator will underperform in the animal regardless of what the protein line says. The third axis is GM status, which is a documentary grade rather than an analytical one, and the fourth is physical form: meal, pellets or a granulated article, which affects flowability, dust and bulk density more than nutrition.
Seasonality and availability
Ukrainian soybeans are harvested from late September into October, and the crush runs through the following months, so new-crop meal appears in the fourth quarter and stocks carry the trade through the year. Meal is not comfortable to hold for long periods: it picks up moisture, it is prone to caking in humid conditions and it supports mould growth if it is stored wet, so the practical rhythm of the trade is continuous shipment rather than long storage. Price follows the international soy complex rather than local conditions, since soybean meal is a globally arbitraged article, but the non-GM premium is a separate and more locally driven number that moves with European labelled-programme demand and with the availability of segregated, certified non-GM origins.
What the buyer checks at intake
- Protein on the contracted basis, checked against the contract wording rather than against the offer sheet. Confirm whether the figure is as-is, dry matter, or protein plus fat.
- Moisture on arrival. Meal above the contracted moisture is a caking and mould risk and it also dilutes the protein the buyer paid for.
- Urease activity, to confirm the meal was adequately toasted and the antinutritional factors were destroyed.
- Protein solubility in potassium hydroxide, to confirm it was not overtoasted. Read together with urease, never alone.
- Fat and crude fibre, which together indicate whether the meal is dehulled high protein or standard with hulls.
- Sand, silica or acid-insoluble ash, which detects mineral adulteration and floor sweepings.
- Salmonella and Enterobacteriaceae on the lot, with the sampling plan named, since feed hygiene is where a meal cargo most often fails.
- Documentary file: GM status declaration or non-GM certification with the segregation scheme named, feed business operator registration, and the deforestation-regulation file where the buyer’s programme requires it.
Where it is used
Soybean meal goes almost entirely into compound feed, and the split across species is what drives the specification. Poultry, both broiler and layer, is the largest single destination and the one most sensitive to available lysine, so it pulls towards dehulled high protein meal with tightly controlled toasting. Pig diets use both grades, with young animal diets demanding the lowest trypsin inhibitor activity. Dairy and beef use the meal as a rumen protein source where formulated economics favour it against rapeseed meal and distillers grains. Aquaculture feed uses high protein, low fibre grades as a partial replacement for fish meal. Pet food uses selected grades where the finished product’s protein and palatability specification permits. Beyond feed, food-grade soy protein concentrates and isolates come from a different, more tightly controlled process stream and should not be conflated with feed meal.
Standards and routes
Meal moves as bulk vessel parcels, in lined bulk containers and in big bags. It is a feed material, so the chain runs on feed law rather than food law: registered or approved feed business operators under Regulation (EC) No 183/2005, undesirable substances under Directive 2002/32/EC, and analysis by the methods in Regulation (EC) No 152/2009. Many European feed buyers additionally require a GMP+ or comparable feed safety certification and a fixed sampling and retention protocol. See the bulk commodity logistics guide for the container against vessel decision on this kind of cargo.
