What is the main difference between a sow and a heifer?

The main difference between a sow and a heifer lies in their respective species and developmental stages. A sow refers to a mature female pig, while a heifer is defined as a young female cow that has not yet borne a calf.

Understanding these definitions is crucial in animal husbandry as the terms are often used in livestock management and breeding. Recognizing the developmental stages of these animals helps farmers and producers in breeding programs, health management, and overall livestock care. In the context of animal agriculture, it's important to distinguish between animals for proper care and breeding practices; hence, knowing that a sow is associated with pigs and a heifer with cattle is essential knowledge.
