Over the past 50 years, global pig production has quadrupled and is predicted to continue to rise. Combined with a changing climate, the pig production industry needs to adopt new feed sources and production systems to remain efficient and sustainable. This chapter reviews the current state of insect production for pig feed globally and highlights challenges and knowledge gaps. The author begins by exploring the nutritional, economic, and environmental benefits of using insects as feed. They then describe the current state of insect production, production and health responses in pigs, and insects' economic and environmental potential as waste consumers. Next the author considers current research into insects as antimicrobials and life cycle assessments on their rearing. Following this, they consider future research, such as alternative insect species, insect welfare, COVID-19's impact on production, and workplace constraints. Finally, the author tackles the challenges to insect production.
