Why are human genes added to the genes of farm animals?

Human genes are added to the genes of farm animals primarily for biotechnological and pharmaceutical purposes. This genetic modification can enhance desirable traits, such as disease resistance or improved growth rates, and can also enable the production of human proteins or antibodies for medical use. Additionally, such modifications can improve the efficiency of livestock production, contributing to food security and economic benefits in agriculture. However, these practices raise ethical and safety concerns that are actively debated.
