Industrial livestock farming, also known as factory farming, is an intensive agricultural approach designed to maximize production while minimizing costs. It involves raising high numbers of livestock like cattle, pigs, and chickens in confined conditions at large-scale facilities known as CAFOs (concentrated animal feeding operations). The livestock eat grain rather than grazing on pastures. Industrial farming has significant economic and food security benefits by increasing yields and efficiency at lower costs through practices like confining animals in concentrated areas to make the most of limited land. However, it primarily applies to common livestock animals like cattle, chickens, pigs, and increasingly other animals that are kept in very small areas of land to more easily manage high numbers with increased output.
