Using nurse sows is a common practice for intensive pig farming because large numbers of piglets per litter result from intensive breeding. This aim of this study was to compare reproductive parameters of nurse sows and non-nurse sows in relation to subsequent reproductive performance. The study evaluated 463 breeding sows that produced at least one litter. The sows were divided into two groups: non-nurse sows (350 sows) and nurse sows (113 sows) at their first farrowing.
