Which of the following best describes the focus of livestock management in agriculture?

The focus of livestock management in agriculture primarily concerns the breeding and care of animals for food or other products. This encompasses a wide range of activities aimed at ensuring animal health, productivity, and welfare while optimizing their use for various agricultural outputs. Livestock management includes practices such as breeding for desirable traits, providing adequate nutrition, managing health issues, and understanding the behavioral needs of the animals.

Livestock is integral to many agricultural systems, serving as sources of meat, milk, leather, and wool, among other products. Effective management practices are essential for maximizing production efficiency and ensuring sustainability within the agricultural sector.

The other options, while relevant to agriculture, do not accurately capture the essence of livestock management. Growing crops and analyzing soil composition relate more to crop production and soil science, respectively. The development of new machinery, on the other hand, pertains to agricultural engineering rather than specifically addressing animal husbandry or livestock care.
