^a-dValues within the same response criteria (across column and row) with no common superscript differ (P < 0.05).

Response values for d 7 to 10 of age for spray-dried animal plasma (SDAP) and soybean meal (SBM) are means of 6 replicates of 7 chicks per pen. Response values for d 18 to 21 of age for spray-dried animal plasma (SDAP) and soybean meal (SBM) are means of 6 replicates of 5 chicks per pen.

Analyzed as a 3 × 2 factorial arrangement of treatments, with 3 diets and 2 ages.
