Hull-on sunflower meal contains crude fiber levels that can exceed 25%, which limits digestibility and energy availability for monogastric animals like poultry and swine. Partially or fully dehulled sunflower meal, with fiber below 15% and protein above 38%, is far more suitable for these species. Ruminants can utilize the higher-fiber hull-on form effectively, so buyers should specify the degree of dehulling and maximum crude fiber content based on the target animal class.

Standard contract parameters include minimum crude protein (on an as-fed or dry-matter basis), maximum crude fiber, maximum moisture (typically 12%), maximum sand/silica content, and whether the product is loose or pelleted. Chlorogenic acid content is occasionally specified for high-inclusion poultry diets, as it can reduce palatability. Buyers should also confirm the degree of hull removal, as this is the primary driver of protein and fiber variability across shipments.
