Ducks can fly. Male ducks and female ducks compared to the female ducks, female ducks can fly close to 30-40m (smaller, complete feathers of the female ducks, flying distance is farther), while the male ducks due to the greater weight, the flight distance is far less than the female ducks, generally only more than 10 meters. Among the females, the flight ability of the females that have just completed the moult and the new females that have just developed their flight feathers is stronger, while the flight ability of the females decreases dramatically when they enter the egg-laying period.
A duck will fly
1, ducks will fly, and the male ducks and female ducks compared to the female ducks, female ducks flying distance is farther, close to the 30-40m or so, while the male ducks flying distance is generally only more than 10 meters (the male ducks weight is larger, poorer flight ability). In the case of smaller, feathered female ducks, the flight distance is even farther (about 40m).
2, in the female ducks, just completed the moulting of the female ducks and the new female ducks have just grown out of the flight feathers of the flight ability, and once the female ducks into the egg laying period, its flight ability is greatly reduced, far less than before.
3, duck feather color is divided into white, black, black and white color three kinds of ducks, including pure black and pure white ducks for pure ducks, flight ability is stronger, and pure black ducks and pure white ducks compared to pure black ducks, pure black ducks smaller, so the flight ability is also stronger.
Second, duck breeding methods
Fertilizing duck breeding techniques are as follows:
1, brooding feeding management (1-3 weeks old)
(1) temperature, humidity
① Infrared lamps are generally used to insulate the nestling ducks, usually every 100-120 ducklings use a 250mm lamp. A 250-watt infrared lamp is usually used for every 100-120 ducklings.
② At the first week of age, the temperature of the brooding room is controlled at about 28 ℃. The second week of age, brooding room temperature control at about 25 ℃. The third week of age, brooder room temperature control at about 22 ℃. At the fourth week of age, the temperature of the brooder room is controlled at about 20℃. Try to keep the temperature stable, avoid high and low.
③ The relative humidity of the brooder room is controlled at about 60-70%.
(2) Feeding density
Ground brooding, for example, the first week of age, 40 per square meter. In the second week of age, 30 per square meter. In the third week of age, 20 per square meter.
(3) light
The first week of age, the whole day to maintain light, light intensity of 5 watts per square meter bulb, bulb from the ground about 2m. In the second and third weeks of age, the length of light is reduced by one hour per day until the length of light is 10 hours per day, while the artificial light intensity is gradually reduced with the reduction of the length of light until 1 watt bulb per square meter. The fourth week of age, the use of natural light can be.
(4) drinking water, open food
① ducklings usually drink water and then open food.
② Drinking water, add appropriate amount of glucose in drinking water or use 0.03% potassium permanganate aqueous solution, drinking for about 1-2 days. Followed by adding the appropriate amount of quick supplement and strong penicillin or haloperidol to the drinking water, to enhance the physical condition of the ducklings, to prevent and control the disease.
③ In 12-24 hours after the shell or one-third of the ducklings appeared to forage for food phenomenon to open food. When opening the food, the sandwich rice or tide show crushed grain material evenly sprinkled in the bedding, let the ducklings free to feed. 5 days of age, plus feed chopped green fodder.
(5) feed formula
① feed formula: 45% corn, four powder 20%, 5% bran, bran 7%, 17% soybean cake, imported fishmeal 6%, appropriate amount of minerals and vitamins.
② per kg of feed contains 12.13-12.55 MJ metabolizable energy, crude protein content of 19.5-22%, calcium content of 1-1.2%, phosphorus content of 0.35-0.45%.
(6) Broken beak, broken wing treatment
At 2-3 days of age, the ducks wing tips are clipped. 2-3 weeks of age, the beak, broken claw treatment. It is important to note that it is not advisable to remove the beaks and claws of male ducks if they are to be kept for breeding purposes.
2, in the nestling feeding management (4-7 weeks old)
(1) feeding
① feed formula: corn 50%, four powder 14%, bran 8%, 10% fine bran, 14% soybean cake, fish meal 4%, the appropriate amount of minerals and vitamins.
② 11.7-12.55 MJ metabolizable energy per kg of feed, crude protein content of 18-19%.
③ When feeding, reduce the concentrate and increase the coarse, supplement the feeding of green fodder and animal feed, to maximize the satisfaction of the duck's demand for feed.
(2) group and feeding density
① In order to facilitate the management, should be based on the area of the feeding site and the actual number of feeding group feeding, usually about 200 per group.
② 4 weeks old, 15 male or 20 female ducks per square meter. 5 weeks old, 10 male or 15 female ducks per square meter. 6 weeks old, 4 male or 8 female ducks per square meter.
(3) Management
①River or pond is required around the farm site.
② In the summer and fall seasons, pay attention to keep the duck house ventilated and breathable to avoid high temperatures.
③ In the middle nestling period, the ducks start to change their feathers, and at this time, you need to pay attention to the prevention and control of feather pecking fetish (add 0.4-0.5% methionine to the feed for 3 days, or add 1% gypsum powder to the feed).
④ Set up a sand dish for the ducks to feed to help digestion.
3, fattening feeding management (8 weeks of age to the pen)
(1) feeding
① feed formula: 60% corn, four powder 10%, bran 8%, 8% fine bran, 12% soybean cake, fish meal 2%, the appropriate amount of mineral vitamins.
② per kg of feed, metabolizable energy should not be less than 13 megajoule, crude protein content of 14-15%.
③ female ducks at 8 weeks of age, male ducks at 9 weeks of age, control the amount of feeding, only to provide 90-95% of the amount of free-feeding (usually 110-125g per female duck per day, 180-190g per male duck per day).
(2) management
① fattening time is about 3 weeks, that is, the female ducks 11 weeks of age, the male ducks 12 weeks of age when the pen for sale.
② During the feeding process, try to limit the range of movement of the ducks, while keeping the surrounding environment quiet.
③ Regular cleaning of the pen, to ensure that the environment is clean and dry, conducive to neat feathers.
