According to the different investment scale, the income of poultry breeding is affected by epidemic diseases, market price fluctuations and other factors, but it is not stable. Unless it can be supplied by futures contracts, as long as full attention is paid to disease prevention.

Ducks are omnivorous animals, with a wide range of recipes and little selective eating. In China, there are famous varieties such as Gaoyou Duck, Beijing Duck and Shaoxing Duck, and the breeding cycle of ducks is relatively short, and they can be released in 42-45 days.

Excellent varieties of meat ducks have high genetic potential of production performance, fast growth, strong disease resistance and high feed utilization rate. At the same age, they consume the same amount of feed and gain much more weight than other kinds of meat ducks.

The feed consumption of ducks will change due to the temperature, humidity, water supply, feed dryness, feeding status and feed quality of the surrounding environment, among which the consumption of feed by temperature is more obvious.

The ratio of protein to energy in meat duck feed should be balanced, and the energy value in feed should be appropriate. When the energy value is too high, the feed consumption will increase, resulting in the waste of some nutrients.

According to the use of ducks, roast ducks are usually released in about 30 days, and meat ducks for segmentation are generally released in 40 ~ 48 days, because the weight gain and feed reward of meat ducks have reached the peak at this time, and the weight gain and feed reward of meat ducks have decreased after 50 days.
