1 Growth performance data are expressed as pen average. 2 SEM = standard error of the mean. 3 Litter quality; score 1 –5, where 1 is dry and porous litter and 5 is wet and caking litter.
At day 36, individual body weights of chicken fed the BioProtein diet were 83 g higher than for the control birds. Average weight gain per pen from 0 to 14 days was significantly (P < 0.02) higher for the chicken fed the BioProtein diet compared to the
