2
Nutrient composition of a composite feed sample collected after farm bin extraction and before it was fed to the birds.
3
Screened feed that yielded reduced abundance of feed fines (RFF) treatments.
4
Added fines feed that yielded increased abundance of feed fines (IFF) treatment.
5
Pellets determined as feed under US sieve number 5.
6
Fines determined as feed over US sieve number 5.
7
Average standard deviation of both pellets and fines parts, each with 10 readings per sample.
