What is the effect of Haida feed?

First of all, I declare that I am an employee of Haida University, so we don't talk secretly. (1) For Haida Feed, the achievements in the last two years should be quite good. We have a lot of data to analyze every month and every year. I think there must be some ponds with poor effects, but as a company, it is difficult to guarantee that every user's income is similar. We can only guarantee that the effect of most farmers is better. Is BMW good? Not annoying.
