Summary and Implications

Sow reproductive performance traits were evaluated in Yorkshire sows from the ISU residual feed intake (RFI) selection experiment. Compared to the randomly selected control line, sows from the line selected for reduced RFI had more piglets born and born alive and the piglets weighed more at birth, had greater pre-weaning growth rates, and weighed more at weaning. However, sows from the select line lost more weight and body condition during lactation than did sows from the control line.
