Have you fed Fuyang strong feed? How is the technical service?

I'm using strong pig feed now, and I feel ok. The feed-meat ratio is relatively low. Their pig feed is very good, and it doesn't cause diarrhea. Is the technical service good? If you have any questions, they will come soon and respond quickly, which is good. Rabbit material has never been used. It should be good. After all, it is an old brand and has been in Fuyang for many years.
