Which wheat particle size is best for grower pigs?

Wheat particle size between 430 to 470 µm has been found to be most acceptable in growing pig diets. The research, carried out by scientists from the Huazhong Agricultural University in Wuhan, China and from New Hope Liuhe Feed, Qingdao, China, found that a quadratic effect of the particle size and average daily gain was observed, with the greatest average daily gain occurring with 430-470 μm. In addition, the increase in the particle size of wheat from 430 to 470 μm increased the number of b
