Gossypol exists in free and bound forms; free gossypol is the toxic fraction and is particularly harmful to swine, poultry, and young ruminants. FDA has established tolerance levels for free gossypol in animal feeds, and exceeding them can cause reproductive failure, reduced growth, and cardiac damage in susceptible species. Buyers should require a certificate of analysis specifying free gossypol content and confirm the meal is suitable for the target animal class before contracting.

Cottonseed meal with hulls removed (dehulled) carries higher crude protein — typically around 41% — and commands a price premium over whole-pressed or hull-on meal, which may test at 36–38% protein. Contracts should specify whether the product is dehulled or whole-pressed and include minimum protein and maximum fiber guarantees, as hull content directly affects nutritional value and feed formulation efficiency.
