Where is the feed quality good?

We use a lot of basic feed, which reflects that the quality is good. I plan to find a better quality material as an agent to do the market next year. Please recommend several feed factories with good quality and high reputation. Don't get me wrong. I want to find a better manufacturer to do business next year, because I have customer resources on hand, and the quality must pass. Our family also raises chickens, and we have used several brands of materials that have not yet caught up with those of Zhongji. I don't know, how about a brand like Prenahijie, because there are no business people here to do it, and we haven't used it! Basically, no matter what brand our family changes, others will follow suit to change the market of about 100,000 chickens. Maybe there are many better products we haven't tried, so I appreciate it when I come up and ask my friends for advice. The quality of Chongqing Zhengda is absolutely reliable when hehe comes to us.
