Fattening techniques of Meat Duck in Winter

Cherry Valley duck, Campbell duck, Beijing duck and Digao duck should be selected for meat duck fattening in winter. Among them, the ducklings are reared for 45 seconds for 60 days, with certain skeletons and muscles, and the fattening is the most suitable when the growth rate is the fastest. There are two common methods.

? First, feed freely and fattening. During the fattening period, a formula feed with high energy and low protein should be used. After feeding, the duck should be put into the water to take a bath and feed on aquatic plants to facilitate digestion. For one of the night snacks, feed and supply water at the same time. Management should pay attention to the dark light in the duck house, so that the duck has less activity and more rest. The place where the duck is closed should be clean and hygienic, and avoid dampness and stench, otherwise it will seriously affect the fattening effect. The reference feed formula is: corn 40%, sorghum 15%, wheat bran 10%, wheat 23%, bean cake 7%, salt 0.5%, shell powder 2%, bone powder 2%, trace element additive 0.5%, poultry multivitamin 5 grams.

? Second, fattening with artificial food. The reference feed formula is: corn 45%, wheat 15%, wheat bran 10%, barley 25%, bean cake 5%, bone meal 1.5%, shell powder 2%, salt 0.5%, trace element additive 0.5%, poultry multivitamin 5 grams. Put the mixture 2ram 3 into a basin and add the same amount of boiling water to blanch, stir into mud, and then add another 1ram 3 dry material. After fully stirring, rub into a rod-shaped plug with a length of 5cm and a weight of about 25g. Rub the embolus with water on your hands to keep the embolus surface smooth and easy to fill. You can do it every two days in winter. In order to prevent the embolus from drying and cracking, cover it with a wet cloth.

The specific operation method of artificial feeding duck is as follows: the duck stuffer sits on the low stool, spreads the duck's wings, sandwiches the duck's wings in the bend of the left leg, holds the duck's upper jaw with the left thumb and index finger, presses the front of the duck's tongue with the middle finger, holds the watery embolus with his right hand, and massages the embolus down the esophagus with his hand. In the initial stage, 4 emboli were filled with 3 Mel per day, and gradually increased to 14 emboli per day. In order to make the ducks get used to filling, the ducks were fed and filled for the first 3 days. Before each filling, check the digestion of the duck. If you find that the digestion is not good, you can fill it once less to prevent accumulated food. Sick and weak ducks are not fattened by artificial feeding.

The main management of artificial fattening ducks is to keep quiet around the fattening duck enclosure. The circle temperature should be kept at 15 ℃-24 ℃ and not less than 5 ℃ in winter. Do not get too high, so as not to affect the fattening effect. The stuffed duck eats a lot of food and needs a lot of water to digest well. therefore, a water basin should be set up in the circle to allow the duck to drink freely. In addition, you have to go into the water for exercise for 2 murals three times a day, each time for 20 minutes, and wait for the duck to shake dry before entering the enclosure.
