1
Dgw: the geometric mean of particle diameter by mass.
2
Sgw: the geometric standard deviation of particle diameter by mass, measure of variation in particle size.
3
Fines determined as feed captured by US sieve number 12.
4
Crumbles determined as feed between US sieve numbers 4 and 12.
5
Pellets determined as feed under US sieve number 4.
6
Screened feed that yielded reduced abundance of feed fines treatments.
7
Added fines feed that yielded increased abundance of feed fines treatment.
8
The standard error of the mean (SEM), n = 3 samples per treatment.
