The experiment studied the effect of oral supplementation of piglets born with less than 3.050kg (LP) (CON: control; COL: 15ml of sow colostrum within 4h from birth), and the effect of cross-fostering 24h after farrowing (CG: litter fixed with less than 50% of the piglets being LP with minimum number of movements; CP: litter fixed with most of the piglets being LP) on litter performance. Forty six litters were used. Litters were allocated to 1 of the 4 treatments: CON-CG, CON-CP, COL-CG, COL-CP. Piglets were weighed on d1 and 19 post-partum. Mortality was recorded. CP sows had lower within litter CV of BW (CVBW) at d1 than CG sows (16.2 vs. 21.9 ± 0.91%, P=0.003) but they did not differ for CVBW at d19 (23.2 vs. 23.4 ± 1.72%; P>0.10). At d19, CG sows had lower number of dead piglets (NDP) than CP sows (0.80 vs. 1.69 ± 0.307; P=0.022) and COL-CG sows had lower NDP than CON-CG (0.47 vs. 1.14 ± 0.160; P=0.062). Cross-fostering LP at the same litter did not prevent from increasing the CVBW at weaning. Colostrum supplementation of LP piglets in non homogenized litters might be the best management strategy to improve litter performance.
