pellet quality, fat exceeding 2% was added postpelleting.
Pellet durability index (PDI) was determined using
the procedure recommended by the American Society
of Agricultural and Biological Engineers (ASAE, 1987).
An amp-volt meter (Model DM-II, Amprobe Instrument,
Lynbrook, NY) was used to calculate energy used during
the grinding and pelleting processes.
All data were analyzed as a randomized complete
block design using the MIXED procedure of SAS (v9.2;
SAS Inst. Inc., Cary, NC) with pen as the experimental
unit and weight as the blocking factor. Orthogonal
contrasts were used to separate treatment means with
comparisons of: 1) mash vs. PCD; 2) PCD vs. pelleted
supplement with corn (PGr and PCr); and 3) PGr vs. PCr.
