Cattle like to eat green feed, concentrated feed and juicy feed, followed by high-quality green hay and low-moisture silage, and least like straw roughage. In the same kind of feed, cattle prefer to eat pellet feed with a length of about 65,438+0 cm, and dislike powder the least. Therefore, when feeding cattle mainly with straw, the straw should be cut short or crushed, mixed with concentrated feed or crushed root and tuber feed, or crushed and pressed into granular feed.
