(A) The advantages of duck breeding cages are to make full use of the space in the duck houses to increase the stocking density and increase the yield per unit area. In the case of ensuring ventilation, generally 60 to 65 animals per square meter, if divided into 2 layers, each square Rice can be raised from 120 to 130. Cage culture can reduce investment in poultry houses and equipment, reduce clean-up work, and can also use mechanized equipment to reduce labor intensity. Small groups feeding, special environment, adequate ventilation, complete nutrition and feed intake. The slaughter time is shortened to about 60 days, saving about 10% of feed costs. Reducing the movement of ducks is conducive to the rapid growth of ducks. Cage raising ducks do not need to be litter, not only to save the expense of grass, but also to make the house less dust and pure manure. Cage culture is completely under artificial control, and is subject to low external stress, which can effectively prevent some infectious diseases and parasitic diseases. Artificial heating is generally used, so the space in the upper part of the house is high in temperature, which saves fuel compared to flat raising; and the breeding density increases, and the body temperature of the young ducklings is also accumulated, which is conducive to heat preservation.
(2) The management of meat duck duck cages is inconvenient, and meat ducks grow fast. They need to be evacuated soon after entering the cage, and they need to be transferred almost every week. Feeding management requires high technology.
(c) The duck sheds and duck cages are to be arranged in the middle 2 rows or 1 row in the north and south, leaving either the middle or the middle. The cage can be made of metal or bamboo wood. 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 0.50 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, which is convenient for ducks 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. The single floor is 1 meter from the ground. Install fecal board between the upper and lower cages, and then connect the fecal board 20 centimeters from the bottom of the upper cage to facilitate excrement removal. (The faucet board can be easily made: a few wooden strips are used as the skeleton, and then placed on the skeleton. A thick piece of plastic cloth, duck dung can fall on the plastic cloth through the bottom mesh.)
(IV) Feed and manage Ducklings should drink 0.02% potassium permanganate within 24 hours after hatching. After drinking water, they can train to eat. Temperatures: 1 to 3 days at 35°C, 4 to 7 days at 32°C, 8 to 14 days at 30°C, 15 to 21 days at 28°C, and 22 to 28 days at 25°C. Humidity: 1 to 7 days of relative humidity 70%, 6 to 14 days of age 65%, 15 to 28 days of age 60%. Illumination: 1 to 10 days of age, 24 hours of full illumination, 11 days of natural light during the day and no lighting at night. Anti-epidemic measures: Ducklings are drinking water with 0.02% potassium permanganate solution from 1 to 5 days and 9 to 13 days of age, and drinking water from 0.02% of furazolidone at 6 to 8 days and 14 to 16 days of age. The excrement on the net bed was swept once a day with a broom, and the plastic cloth under the net bed was removed once a day and the faeces were used to feed the 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. Effectively controlling the occurrence of these diseases is the key to the success or failure of ducks. 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. Observe the ducks carefully, and treat them in case of illness.
