Rapid fencing technique of raising meat ducks in three-dimensional cage

1. Advantages of caged meat duck culture

First, it can make full use of the duck house space, increase the feeding density and increase the output per unit area, and second, mechanized equipment can be used to reduce labor intensity. Third, the nutrition of the diet is perfect, the food intake is uniform, and the time of going out of the column is shortened to about 60 days, saving about 10% of the feed cost. Fourth, cage breeding is completely under artificial control and is subject to little external stress, which can effectively prevent some infectious and parasitic diseases.

2. Installation of duck houses and cages

Use 2 rows in the middle or 1 row in the north and south, leaving a pass on both sides or in the middle. Each cage is 2 meters long and 1.2 meters wide, with bamboo strips or barbed wire and 1.5 square centimeters of mesh on the floor. There is a 0.5-meter-high fence on all sides, which is nailed with wood strips 2.5 cm wide and 2 cm thick, with a spacing of 3 cm to 4 cm, which is suitable for ducks to eat and drink. Material trough and sink should be set in front of the fence, or automatic drinking fountains should be installed. According to the space in the room, the cage can be stacked on two or four floors, with the upper floor 1.2 meters away from the ground and the lower floor 0.6 meters away from the ground. Install a dung plate between the upper and lower cages, which should be 20 cm away from the bottom of the upper cage to facilitate the removal of dung.

3. Rapid weight gain feed formula (1) ducklings (days 1-25) feed requirements (%): crude protein 20, crude fiber 3.9, calcium 1.1, phosphorus 0.1; reference formula (%): corn 50, vegetable cake 20, broken rice 10, wheat bran 10, fish meal 7.5, meat meal 1, shell meal 1, salt 0.5. (2) the feed requirements of middle ducks (26 ~ 45 days) were as follows: crude protein 17.5, crude fiber 4.1, calcium and phosphorus 0.5. Reference formula (%): corn 50, wheat bran 12, broken rice 10, salt 0.5, vegetable cake 5, big (small) wheat 17, fish meal 4.5, shell meal 1. (3) fattening formula (%): corn 35, flour 26.5, rice bran 30, beans (fried) 5, shell powder 2, bone meal 1, salt 0.5 in the early stage, corn 35, flour 30, rice bran 25, sorghum 6.5, shell powder 2, bone meal 1, salt 0.5 in the later stage.

IV. Comprehensive epidemic prevention measures

Ducklings aged 1 to 5 days and 9 to 13 days old drank with 0.02% potassium permanganate solution, and ducklings aged 6 to 8 days and 14 to 16 days drank water with 0.02% dysentery solution. The feces on the Internet are swept once a day, and the stool plates are cleared once a day. The feces can be used to raise fish or feed pigs. The outside of the duck house should be disinfected with lime water every 7 days. The common diseases of ducklings are duck plague, cholera and viral hepatitis. Vaccination should be carried out regularly. The method is as follows: 1-day-old ducklings were vaccinated with attenuated viral hepatitis vaccine (injected according to instructions), and ducklings were injected with duck plague chicken embryo attenuated vaccine at 20 days old. Usually, drugs can be added to the feed for prevention, 0.1% oxytetracycline powder can be added every 5 to 7 days for 3 days. Also pay attention to observe the duck flock, once the disease occurs, timely treatment.
