What aspect of agriculture focuses on the breeding and genetics of farm animals?

Animal husbandry is the aspect of agriculture that specifically deals with the breeding and genetics of farm animals. This field encompasses various practices aimed at improving the health, productivity, and welfare of livestock. It involves the selective breeding of animals to enhance desirable traits, such as growth rates, disease resistance, and reproductive efficiency.

In contrast, agronomy pertains to crop cultivation and soil management, focusing primarily on plants rather than animals. Horticulture is the science and art of growing fruits, vegetables, flowers, and ornamental plants, again leading back to plant production rather than animal breeding. Poultry science, while closely related to animal husbandry, focuses specifically on the breeding and management of birds raised for meat and eggs, rather than encompassing all livestock and their genetic improvement. Thus, animal husbandry is the broadest and most accurate choice for the breeding and genetics of farm animals as a whole.
