Fig. 2From: Sow performance in multi-suckling pens with different management routinesDays from weaning to standing estrus distribution in different management routines (W1–W3). The interval from weaning to standing estrus was shorter for W2 (2.7 days ± 0.2; P < 0.05) and W3 (2.4 days ± 0.2; P < 0.001) than W1 (3.8 days ± 0.2). There was no difference between W2 and W3Back to article page
