Meat duck cage can be quickly slaughtered

Duck cage raising can increase the yield per unit area and reduce the labor intensity. Its slaughter time is reduced to about 60 days, saving about 10% of the feed cost. The technique is as follows: 1. Duck house and duck cage setup. Use 2 rows in the middle or 1 row in the north and south, and leave them on both sides or in the middle. Each duck cage is 2 meters long and 1.2 meters wide. It uses bamboo strips or wire mesh. The floor mesh is 1.5 square centimeters. A fence with a height of 0.5 meters is set around the fence, and the fence is nailed with a wooden bar 2.5 centimeters wide and 2 centimeters thick. The distance between the wooden bars is 3 to 4 centimeters so as to facilitate the duck to eat and drink water. Troughs and sinks should be placed in front of the fence or fitted with automatic drinkers. The cage can be set according to the space in the room, stacking 2 to 4 layers, 2 stacked layers, the upper floor is 1.2 meters above the ground, and the lower floor is 0.6 meters above the ground. In the upper and lower cages installed between the next two feces, then the feces to the basket from the top of the cage 20 cm, in order to facilitate excrement. Second, rapid weight gain feed formula. (1) Feed requirement (%) for ducklings (days 1 to 25): Crude protein 20, Crude fiber 3.9, Calcium 1.1, Phosphorus 0.1; Reference formula (%): Corn 50, Biscuit 20, Broken rice 10, Bran Peel 10, fish meal 7.5, meat powder 1, shell powder 1, salt 0.5. (2) Medium-duck (26th to 45th days) feed requirements (%): crude protein 17.5, crude fiber 4.1, calcium and phosphorus 0.5; reference formula (%): corn 50, bran 12, broken rice 10, salt 0.5, Vegetable cake 5, large (small) wheat 17, fishmeal 4.5, shell powder 1. (3)Fattening period formula (%): pre-use corn 35, flour 26.5, rice bran 30, beans (fried) 5, shell powder 2, bone meal 1, salt 0.5; later with corn 35, flour 30, rice bran 25, sorghum 6.5, shell powder 2, bone meal 1, salt 0.5. Third, comprehensive prevention measures. Ducklings were fed drinking water with 0.02% potassium permanganate for 1 to 5 days and 9 to 13 days of age, and drinking water with 0.02% of furazolidone at 6 to 8 days and 14 to 16 days of age. The excrement on the web is swept once a day. The faeces are removed once a day and the excrement can be used for raising fish or feeding pigs. The duck house should be sterilized with lime water once every 7 days. Common diseases of ducklings include duck gizzards, cholera, and viral hepatitis. To be regularly vaccinated. The method is: 1 day old duckling virus hepatitis virus attenuated vaccine (injected according to the instructions), 20 days old ducklings injected duck pheasant embryo attenuated vaccine. Normally, drugs can be added to the diet for prevention. 0.1% oxytetracycline powder can be added every 5 to 7 days and fed for 3 days.
