The compound feed of the invention does not contain antibiotics, and is developed for the requirement of bone development and reduction of subcutaneous fat deposition in meat ducks under the circumstance of restricted feed intake, which can ensure the bone development requirements of meat ducks after 33 days of age, and reduce the time of slaughtering. The proportion of weak ducks improves the uniformity of the overall duck group, increases the overall income of breeding, and can reduce the subcutaneous fat deposition of meat ducks, thereby improving the flavor and taste of duck meat. |
