Which of these is considered an applied science?

Animal science is considered an applied science because it focuses on practical applications of scientific knowledge to improve animal health, productivity, and welfare. This field integrates various disciplines, including biology, genetics, nutrition, and veterinary medicine, to address real-world challenges related to animal husbandry and agriculture.

In animal science, the principles of biological and chemical sciences are used to develop effective breeding strategies, optimize feeding practices, enhance animal health, and improve management systems. This emphasis on applying scientific principles to improve outcomes in agriculture and livestock production distinguishes it as an applied science.

The other fields mentioned, such as biochemistry, biology, and chemistry, primarily focus on theoretical foundations or fundamental research. While they absolutely contribute valuable knowledge to animal science, they do not emphasize the direct application of this knowledge to practical problems in the same way that animal science does.
