The main difference between ducks fed with rice and ducks fed with feed is the growth time. Of course, in terms of meat quality, ducks fed rice have fresh taste and tough meat quality. Feed ducks are softer and less fresh.

The reasons for this situation are: scientific feed proportion, balanced proportion of various nutrients, high feed utilization rate, fast growth rate and less amino acids precipitated in the body. However, the proportion of amino acids in ducks raised by rice is unbalanced, the feed utilization rate is low, the growth rate is slow, the growth time is long, and there are many amino acids accumulated in the body, and amino acids are the source of umami flavor. Coupled with long growth time and large amount of exercise, the meat is stronger and more resilient.
