Cross-fostering of piglets at birth has been recommended in order to optimise the rearing capacity of the sow and to standardise piglet weights at weaning (English et al., 1977). However, repeated cross-fostering is often practiced in industry which is stressful for the sow and her piglets resulting in lower weaning weights (Robert and Martineau, 2001). The effect of cross-fostering on piglet growth may differ among piglets with high or low birthweights, which could provide avenues to optimise cross-fostering practices. |
