Final answer:
No, the color of fat in cows does not determine their value. It is influenced by their diet rather than their age. Various factors like breed, weight, and health determine the value of cows.
Step-by-step explanation:
No, old cows are not discounted compared to young heifers because they have white fat.
The color of fat in cows is influenced by their diet rather than their age. The fat in cows can be white, yellow, or even slightly pink depending on their diet. For example, cows that are fed on a diet rich in carotenoids, such as grass, produce yellow fat. On the other hand, cows fed a diet low in carotenoids, such as grains and corn, will have white fat.
The value of cows typically depends on other factors such as their breed, weight, and overall health, rather than the color of their fat.
