Technical points of dried up ducks

Recently, some farmers asked in a letter that they wanted to develop a breeding duck, but there was no water near the house and asked whether the duck could be raised. The answer is yes, the duck can be raised.

Ducks are raised in cold weather and can maintain a high ambient temperature; they can avoid the loss of energy from ducks caused by water baths; they can avoid the harm of parasites in the body and thus get higher feed rewards. However, the ducks are raised and raised and the investment in duck houses is relatively large.

Dry and raised ducks are generally divided into brooding (0 to 21 days) and fattening (22 days to slaughter).

During brooding, they can be raised in multiple layers. The distance between the layers is 60-70 cm, each layer is about 60 cm wide, and the length is determined by the size of feeding, 15-20 ducklings per square meter. Use wire mesh as net material, load bearing bamboo strips, and install fecal layer under bamboo strips (usually with old feed fiber bags). Place a plastic trough and a drinker on the wire mesh.

During brooding, they can also be raised on the ground, but more straw is used as a litter. Place a grid in the place where the waterer is placed so that it can leak the splashing water and export it outdoors to keep the duck house dry.

Cold brooding should be warmed up and heated by infrared lamps, biogas or coal-fired boilers, but the latter two should use pipes to direct the smoke and exhaust gas outdoors. During the brooding period, the temperature in the house should be maintained at 30°C on the 1st day and then decreased by 1°C every 2 days thereafter. When the temperature is 21 days or the average temperature reaches 25°C, the temperature is defrosted. In addition, ducks enter the first week, ducklings like yards, should be opened every 2 hours to prevent death.

Compared to white meat ducks, the ducklings are active and must be “saturated with pressure” to ensure that there are feed and drinking water in feed troughs and drinkers within 24 hours, and ducks can eat and drink water at will. There must be light at night.

The feeding nutrition of the ducklings during the brooding period can be slightly lower than that of the white feather ducks. The crude protein content is 18%, the lysine content is 0.9%, and the methionine plus cystine content is 0.65%. If there are only white ducks and ducks in the market, the crude protein content of 19%-20% can be purchased with 10% broken rice or ground corn. A small amount (about 0.3% of the amount of feed) of large grains of sand must be added to the feeders for raising ducklings so that the stomach can grind food.

The major contagious diseases of the ducks are viral hepatitis and infectious serositis, so ducklings should be injected subcutaneously in the neck at 1 to 2 days of age to prevent these two diseases.

The drought-fed raising period of the ducklings is generally raised on the ground, with 6 ducks per square meter. Due to the large amount of duck excrement at this stage, it is necessary to pad straw twice a day sooner or later to ensure that the ducks sleep on the straw and cannot sleep on Gong. If there are trees in the front of the house or in winter, the ducks can be released on sunny days. The feed tanks and drinking fountains can also be moved out, and they can be stored in duck houses at night.

During the fattening stage of the duck, the feed requires crude protein content of 14% to 15%, lysine content of 0.7%, and methionine plus cystine content of 0.6%. If there is only white meat ducks in the market, that is, the crude protein content is 16%, you can buy 10% corn or rice and a small amount of rice bran (with a small amount of broken rice and rice bran, crude protein content of about 3%, Instead of reconciliation, provide water for the entire day.

Ducks are generally kept for 40 to 50 days and weigh up to 1.8 to 2 kg. Wings are sold for a long period of time. If you continue to feed it, you will consume more feed and you will have less daily gain.
