Table 9 Results of the four linear mixed-effects models: with treatment group as explanatory variable and 1) average daily weight gain per pig (ADG) in nursery, 2) ADG in fattening and 3) feed consumption in the fattening as outcome, as well as 4) straw consumption as explanatory variable and feed consumption in fattening as outcome; each model with batch as random effect (random intercept)
From: Provision of straw by a foraging tower –effect on tail biting in weaners and fattening pigs
