Table 5.
Litter quality scores of pens with broilers receiving no larvae (Control), or provided with live larvae in different amounts (5 or 10% of the total dietary DM replaced with larvae, A5 and A10 respectively) and provisioning methods (scattered four or seven times a day, S4 and S7 respectively, or in tubes, called TB). Visual friability and wetness scores were analysed with a Kruskal–Wallis test and a post-hoc DSCF test and moisture percentage was analysed with a generalized linear mixed model. 1sum of scores calculated by a Kruskal–Wallis test. **p < 0.01.
