The results show that digestibility of the same diets is indeed higher for gestating and lactating sows than it is for growing pigs.

Making use of the NET energy system for sows to formulate feeds makes it possible to achieve a smooth transition from gestation to lactation diets, which makes the transition period around farrowing easier for the sows.
The nutrient requirements of the sow change during gestation and the feed provision must meet this demand; hence the need for phase feeding.
Feeding growing-finishing pigs with daily tailored diets using precision feeding techniques is an effective approach to reduce nutrient excretion, without compromising pig performance or carcass composition
The provision of trace minerals at the correct level and in their organic form is essential for the modern hyper-prolific sow: they have been shown to increase litter size, the quality of the piglet at birth and weaning and weaning weight and to reduce sow lameness and premature culling.
The factor that is completely ignored is that newly weaned piglets develop edema; they retain water in their tissues above what is normal and this explains the abnormal gain of the piglet in the first days after weaning.
Piglets have little difficulty finding the feeder but piglets that were not exposed to creep feed during lactation do not recognize the feed as food when weaned.
