¹Values represent the mean of 8 replicates per treatment with 6 broilers per pen. NS = nonsignificant at P > 0.10. Powder = spray-dried powder plasma (AP 920) [7]; Granular = spray-dried granular plasma (Appetein) [7].

²Contrasts were as follows: 1) control (treatment 1) vs. SDP (treatments 2, 3, 4, and 5); 2) Powder (treatments 2 and 3) vs. Granular (treatments 4 and 5); 3) SDP continuous feeding (treatments 2 and 4) vs. SDP discontinued feeding (treatments 3 and 5); 4) interaction of feeding duration and form of SDP (treatments 3 and 4 vs. 2 and 5).
