Which of the following is a qualifying use under conservation use for livestock?

Managing poultry is a qualifying use under conservation use for livestock because it aligns with the conservation practices aimed at promoting sustainability and proper resource management in agricultural settings. Conservation use generally includes practices that support the health and productivity of both livestock and the environment. Poultry management contributes to nutrient cycling, pest control, and the use of natural resources, which supports overall ecosystem health.

In contrast, the other options focus on specific types of livestock or activities that do not necessarily meet the broader conservation objectives. Dairy cattle and hog farming, while significant in agricultural production, do not encompass the same range of conservation practices associated with poultry management. Horse racing is primarily an entertainment and competitive activity rather than a farming practice concerned with conservation, making it an unsuitable option within this context.
