Innovation in Swine Nutrition in China over the Past Decade

Food security and environmental challenges have reached a critical point that demands transformative interventions. In this context, optimizing swine nutrition emerges as a pivotal area of research. As the largest pork producer globally, China has achieved initial large-scale swine farming through the modernization of its feed industry. In the past decade, Chinese swine feeding standards were established to conduct modern analyses of nutritional requirements. Meanwhile, quality control strategies and sustainable development plans were developed to form a low-carbon, efficient, and internationalized production model. This review systematically addresses significant challenges in the swine industry, such as protein feed shortages, declined meat quality, antibiotic overuse, excessive mycotoxin levels, and environmental threats linked to intensive farming. It emphasizes targeted strategies, including precision feeding, waste recycling in circular agriculture, mycotoxin degradation, and antibiotic alternatives, which are proposed to address these issues. Under the future trends of the modern smart livestock industry, advancements in synthetic biology, artificial intelligence, molecular technologies, and carbon reduction practices are anticipated to further refine swine nutrition, thereby improving feed efficiency, animal welfare, and sustainable practices in alignment with the global "One Health" initiative.
