Which of the following best describes animal husbandry?

The description of animal husbandry as the care and management of farm animals encapsulates the primary focus of this discipline, which involves a systematic approach to raising animals for various purposes such as food, fiber, and other products. This encompasses a range of practices including breeding, feeding, housing, health care, and welfare considerations, all aimed at optimizing the productivity and quality of animal products while ensuring the well-being of the animals.

While the environmental impact of animal farming is indeed an important aspect of agricultural practices, it pertains more to the consequences of farming methods rather than the direct management and care of the animals themselves. The study of animal psychology, though relevant to understanding animal behavior, does not cover the broader scope of husbandry practices that include nutrition and health management. Additionally, the marketing of animal products focuses on the economic aspects of animal agriculture rather than the day-to-day care and management processes inherent to animal husbandry. Thus, identifying animal husbandry primarily with the care and management of farm animals accurately reflects its comprehensive nature within the field of animal sciences.
