Means in the same row with different superscripts are significantly different (P< 0.05).

Data are means of 3 batches of FFSMP, each batch was tested in triplicate.

Control: Unfermented feather meal-soybean meal product.

N21: Fermented feather meal-soybean meal product (FFSMP) inoculated with Bacillus subtilis var. natto N21; CU14: FFSMP inoculated with Bacillus subtilis CU14; CU33: FFSMP inoculated with Bacillus amyloliquefaciens CU33.
