What kind of pig do you raise? 1% composition is unknown, but the protein is too low. Jy718 protein is low, but the culture effect is good! Does it need to be improved so magically? -- No need to improve-- corn 65 wheat bran or rice bran 10 concentrate 25mer- -Corn 65 wheat bran or rice bran 10 concentrate 25lqj released on 2009-11-5 11:14 do not understand?
