ABSTRACT: The effects of treatment methods on the nutritive value of cotton seed cake (CSC) for laying hens were examined. Olympia laying hens (n = 96) were assigned randomly to a 2 × 3 factorial combination of fermented or unfermented CSC supplemented with enzyme, Vitamin E and ferrous sulphate over a 4-week feeding period. CSC was incorporated at 15% in the diets. Results showed no significant differences (P > 0.05) in feed intake, body weight gain and egg weight due to treatments. However, hen-day egg production was significantly reduced (P 0.05). Serum concentration of total protein among dietary treatments was lower (P 0.05) for all treatments. Generally, activities of alanine and aspartate aminotransferases increased (P
