When formulating compound feed for meat ducks and laying ducks in different regions, different breeding enterprises or farmers, they should fully consider the actual production level and feed sources of poultry in the region and local enterprises. The feed is formulated according to the physiological stage, production performance characteristics, feeding environment, food nutritional structure characteristics of grazing ducks, etc. This feed formula is proposed based on the current general situation of raising meat ducks and laying ducks in ordinary duck farms in my country, and is for reference only by breeding enterprises (Table 26, Table 27). The additive premix in the formula consists of methionine, lysine, multivitamins, trace elements and carriers.
