Second parity sows may have suboptimal farrowing rate and litter size, resulting from relatively high weight losses during first lactation. Sows with low performance in second parity on average also have a lower performance in later parities and increased chances of early culling. To overcome this reduced second parity reproductive performance, feed intake during first lactation needs to be improved. To realise this, both pre-farrowing and lactational –nutritional- management needs to be optimised. On the other hand, also post-weaning management strategies can influence second parity performance. Improved follicle recovery prior to insemination can be achieved by applying either skip-a-heat, or daily altrenogest treatments. These both postpone insemination time after oestrus, resulting in improved performance.
