How is selective breeding used for farming with animals?

Selective breeding in farming involves choosing specific animals with desirable traits to reproduce, enhancing those traits in future generations. This technique can improve productivity, disease resistance, growth rates, and specific characteristics like milk production in dairy cows or muscle mass in livestock. By carefully selecting parents, farmers can optimize their herds or flocks for better performance and profitability. Ultimately, selective breeding helps meet consumer demands and improve overall animal welfare in agricultural settings.
