Sow nutrition programs focusing on reducing feed costs
Many pig producers try to fine-tune sow nutrition, particularly during the gestation period. High raw material prices and increased feed costs are spotlighting sow gestation nutrition to improve cost-efficiencies, while maintaining or improving productivity in pig breeding herds.
It is now more typical to follow a ‘high-low-high’ feeding schedule. This is based on the idea that in the first part of the gestation the weaned sows need to recover from lactation losses.

Sow nutrition: Avoiding second parity slump
About 50 percent of all sows have a lower litter size in their second parity, compared with their first parity – and recent studies indicated that second parity litter size and litter size could be related to subsequent litter sizes and farrowing rates. However, by altering management and sow nutrition pig producers may be able to reverse this trend and improve second – and subsequent – parity reproductive performance.
The results of two recent studies on the effect of sow lactation weight loss on reproductive performance.
