1

Spray-dried animal plasma and soybean meal were fed to cecectomized roosters as a 50% blend with corn; amino acid digestibility values were calculated by the difference procedure, factoring out the corn contribution.

2

Standardized digestibility values are means of 4 individually caged cecectomized roosters.

3

Digestible concentrations = (total × standardized digestibility value)/100.

4

SEM for standardized digestibility values. The probability value for the model from the ANOVA was P < 0.0001 for all amino acids, indicating that standardized digestibility values for all amino acids in spray–dried animal plasma were significantly higher than soybean meal.
