摘要
Maximizing sow reproductive performance is vital for ensuring healthy piglet supply,feed efficiency,and profitability,which requires understanding factors such as nutrition,disease control,genetics,herd management,and their interplay.It is well documented that most reproductive issues in sows stem from extreme fluctuations in body reserves[1].Thus,optimizing reproduction should prioritize regulating body reserves and making continuous nutritional adjustments throughout a sow’s life[1,2].However,the traditional one-size-fits-all feeding strategy may not meet individual sow needs under varying conditions.This feeding strategy leads to nutrient under-or over-feeding,which may result in a lack of performance and health issues on the one hand,and economic loss and negative environmental effects on the other.
