In gestation, the main objective of the feeding program for sows is to regain any condition or body weight lost during lactation and to ensure that the sow reaches her subsequent farrowing in the correct condition.
Weaning to Oestrus
The objective at this stage is to maximize feed intake in order to start the process of regaining any body weight and backfat losses in lactation. Feeding a high feed level (≥3.5 kg+) between weaning and breeding has been shown to increase ovulation rate and embryo survival. If the weaned sow is in a good body condition, then she must be fed no more than 2.5 kg per day
