  2. BCS Body Condition Score, N Obs number of records for each trait, % Obs percentage of observations for each class of a given factor, M:Pa Mating to Early pregnancy, Pa:L Early pregnancy to Lambing, Pa:W Early pregnancy to Weaning, L:Sa Lambing to Early suckling, W:Wp Weaning to Post-weaning, W:M Weaning to Mating. Sign., the significance probabilities for each fixed effect of mixed models are provided as: *** P-value < 0.001, ** P-value < 0.01, * P-value < 0.05; NS, not significant. The lower case letters (a, b, c, d) indicate significant differences in the trait between classes of each factor (i.e., values not sharing a common letter are significantly different as determined by a t-test at p < 0.05)
