Breeding ducks generally refer to middle-aged ducks from 5 weeks old to pre-opening, also known as young ducks. This is a transitional phase from brooding to egg production. At this stage, the bred ducks have a rapid growth and development, a strong ability to move, can eat and sleep, and have a wide diet, and need to provide more abundant nutrients. When grazing, if the animal husbandry is rich in natural feed, or if the venue is good, the ducks often rush around and refuse to rest. At the same time, the bred ducks are sensitive to nerves, strong in gregariousness, and have greater plasticity. They are suitable for training and cultivating good living patterns. According to this feature, after each fulness, it is necessary to bathe, comb, and then go to bed and sleep. After this habit is established, the bred duck grows quickly.
1. Grazing Feeding Grazing rearing can save a lot of feed and reduce costs, and at the same time it can enhance the physique of ducks. It is more suitable for the small-scale breeding of farmer households, and less application of hens in intensive production. Grazing rearing should pay attention to the following points: (1) Grazing upstream and catching pastows downstream. In general, when they are grazing, they have enough energy and strong appetite for food. They should go upstream. When the harvest has been full, and one day of activity must be tired, it should be down the river, quickly return home. In the spring and fall winter seasons, in case of windy weather, the weather should be grazing and grazing, avoiding the wind lifting duck feathers, excessive heat loss, and the duck body getting cold. (2) The new ducks must press and the old ducks must force them. The mother duck was energetic, active, and happily ran ahead, especially in areas where there was more feed, allowing her to feed on the ground. In the second year she was slow, after she had eaten. If you can't afford to lie down, you should often rush to make it go swimming or look for food. (3) Heatstroke prevention and antivirus. In the summer, we must pay attention to sunstroke prevention, return to the early morning and return, and let the duck rest in the shade at noon. During the summer harvest, the farmland can be released when the weather is cool in the morning and afternoon, rushes to rivers and lakes in the depths at noon, and feeds ducks to see if the hunger level is properly fed in the evening, and activities are carried out late at night in the sports grounds. . There are many pesticides used in summer, and during grazing, it is necessary to prevent the occurrence of phytotoxicity. (4) Cold protection. During the winter, the ducklings must collect the animals early, and release the animal husbandry lately. The duck houses should be used to cut off the wind, cut off the rain and cut off the snow. At the same time, it is necessary to constantly change the bedding to keep the duck houses dry and warm. The winter temperature should be above 10°C.
2. Half-feeding group The rearing duck group is kept in duck houses, land sports grounds and water sports grounds, and is not grazing outside. Food, drinking water can be set up in the house, but also outside the house, generally no drinking water system. This kind of rearing method is generally combined with fish ponds to form a benign duck-fish integrated ecological cycle, which is one of the main ways of ducklings in the current rural areas in the region.
3. Whole-feeding confinement Whole-feeding confinement means that the whole breeding process of the rearing duck is always carried out in the duck housing. In general, the duck houses can be reared with thick litter, netted ground, and plowed ground. Generally, a relatively complete drinking water and drainage system is required in the house. The advantage of this feeding method is that it can better control the feeding environment and is mostly used for large-scale intensive breeding of laying ducks.
1. Feeding density The breeding density of captive ducks varies with the age, season and temperature of the duck. Generally, it can be grasped according to the following criteria: 4 to 10 weeks old, 10 to 15 per square meter; 10 to 20 weeks old, per square 8 to 10 meters. When the winter temperature is low, the rearing density may be slightly higher; when the summer temperature is higher, the rearing density may be slightly lower.
2. The small groups of grouped young ducks may vary in size, but the composition of each duck group should not be too large. General grazing ducks with 500 to 1000 per group is appropriate, while the feeding ducks can be divided into small pens, each small column 200 to 300. At the same time, grouping should be done as close as possible to the same age, size, species, and gender of the ducks.
3. The light of the bred ducks should be short and should not be long. Generally from the age of 8 weeks, the light should be 8 to 10 hours per day, and the light intensity should be 5 lux. At other times, the overnight light should be kept on, usually 30 square meters. The ducklings were to be fitted with a 1-15 watt light bulb or a kerosene lamp with a glass cover.
4. Feed restriction Feeding is mainly used for captive breeding and semi-circling duck populations, while grazing ducks generally do not require limited feeding due to large amounts of exercise. Restricted feeding generally starts from 8 weeks of age and ends at 16-18 weeks of age. Restriction should be weighed before feeding, and then every two weeks after the sample weighing 1 time, in order to control the body weight in the appropriate range of the appropriate species, overweight or light weight will affect the egg production of ducks.
5. Sports captive and semi-circle duck groups should increase the amount of exercise properly. Usually, they can do regular circling movements every day for 5 to 10 minutes each day and 2 to 4 times a day.
