US - The byproduct value is the total value of all non-meat items produced from an animal such as cheek meat, hearts, livers, tripe, tongue, meat and bone meal, edible and inedible tallow, and hides, write Steve Meyer and Len Steiner.These byproduct values are a key factor for packer margins. Exports are a driver of most byproduct values as there is a much higher consumer preference for variety meats in overseas markets including Asian countries and Mexico.On the cattle side, US hides make up a majority of the byproduct value, and most hides are processed overseas.Transitioning to hog byproduct values, they have seen more of an uptick in prices recently compared to beef.

　　史蒂夫·迈耶(Steve Meyer)和莱恩·施泰纳(Len Steiner)写道，所谓副产品价值就是在动物加工后的无肉产品总价值，譬如颊肉、心脏、肝脏、牛肚、肉骨粉、舌头、食用牛油等。副产品价值是获得边际利润的一个关键因素。出口是副产品价值最大化的驱动器，海外市场有许多偏好各种肉类的消费者，包括亚洲国家和墨西哥。譬如牛肉加工，美国隐蔽了大部分副产品价值，许多隐蔽的牛肉副产品都在海外加工。过渡到猪肉副产品价值，相比牛肉副产品可以看到最近的价格上涨。
