Final answer:
The statement typically refers to the hide being historically the most valuable part of an animal's by-products. However, market dynamics can change, so the current greatest contributor to the USDA's Estimated Hide and Offal Value can vary. Checking the latest USDA reports would give the most up-to-date information.
Step-by-step explanation:
The question is asking whether the statement "The greatest contributor to the USDA's Estimated Hide and Offal Value is the hide" is true or false. Hide and Offal values are part of the whole animal's economic value in addition to the meat, and they fluctuate depending on market demand and other factors. Historically, the hide was indeed often the most valuable part of the by-products, largely due to demand for leather goods. However, this might not always be the case as market dynamics can change with new technology, changes in fashion, and other economic factors affecting demand for different types of offal products. It would be best to refer to current USDA reports or market research to determine the present greatest contributor to the USDA's Estimated Hide and Offal Value.
