Filling duck fattening techniques

Filling duck fattening is an artificial forced fattening method. Ducks start fattening 10-15 days before listing and can be listed when they weigh around 2.6 kg. This fattened duck can form a "flower between the flesh" and also accumulates a layer of fat under the skin. It is made into roast duck with crisp and tender skin and aroma. In the following, the author used the feeding and management methods of Beijing duck fattening in recent years to briefly describe it as follows.

6-7 weeks old, about 1.75 kilograms body weight, medium-strong ducks were selected and grouped according to size and sex. Generally, the male ducks grow faster than the female ducks. When the fatteners are fattened, the food intake is grouped according to the size of the body weight to master the uniformity. To ensure the quality of the duck, the toenails should be cut to avoid scratching other ducks. Feed for ducks has an energy level of 11.5 to 12.5 MJ/kg of metabolizable energy and 14-15% of crude protein. The table below shows feed formulation formula for Beijing Duck.

The amount of filler should be gradually increased according to age and growth, do not suddenly increase, to prevent strangulation or due to indigestion caused by paralysis.

When filling a duck, it is required to open the mouth quickly, press the tongue steadily, intubate the tube, eat slowly, and spread the duck fast. When the feeding operation is correct, it is fast and safe. Hot days, rainy days, loss of appetite, susceptible to indigestion, at this time should be reduced or no food. The amount of material used for feeding ducks is measured in dry powder terms, 250-260 grams per day, and is divided into 4 times. Generally, the feed materials for ducks are all thin materials, and the mixed materials are prepared with water to prepare a thick porridge-like mixture. Thinner, later thicker. To aid digestion, the feed was brewed for the first 4 hours prior to filling and then fed on a semi-automatic feeding machine. When hot, it is not necessary to brew with water first, or soak only for 1-2 hours so as to avoid deterioration of feed fermentation. When filling, there is an undigested food product in the crop, which should be filled or not filled. Because the filler is much more than the free intake and the heat production is large, it must be supplied with sufficient drinking water. Because of the rapid growth at this time, in addition to having sufficient energy and protein, special attention must be paid to calcium and phosphorus in the diet. proportion. After the filling, the ducks should be bathed immediately to help digestion and the body should be enhanced. However, the bath area should not be too large and the time should not be too long. After filling, the ducks do not like to walk around, stay on the floor for a long time, the legs are easy to lick, and the chest is also prone to dead spots or congestion. Therefore, it is recommended to move slowly and erratically every 2-3 hours. It is forbidden to kick and kick the club to prevent it from squeezing. The method of catching ducks should also be noted that the neck must be lightly gripped and gently lifted to prevent scratching. The duck must not be thrown in order to avoid damage and affect the quality of the feed.
