For example, cattle that are too well fed have thick fat deposits that stretch their skin in places, resulting in a lower-quality leather. Raising cattle naturally in pastures also affects the quality of the leather. The fences around pastures are electrified, and cattle are prone to stampede. When they run into such fences, they scar their skin.
舉例來說，有些牛太貪吃，以致脂肪較厚的部位會被撐開，皮質不細緻；而牛的產地是自然放牧或圈養也有影響，圈養的圍欄有通電，愛亂跑的牛會被燙傷，導致牛皮破相。
