Table 2 Results of unifactorial analyses (factors with pvalue < 0.1) and final multifactorial model (factors with pvalue < 0.05) for MOR (mortality score). R² of final model = 17.54 %. Factors remaining in the final model are in bold letters, and the reference level is in italic letters (BFCD benefits free of direct costs, LWG live weight gain)
