Feeding and management techniques of green-headed wild ducklings

From hatching to 3 weeks of age is the brooding stage of wild ducks. careful feeding and management should be given according to the necessary conditions for the growth of ducklings.

Selection and transportation of ducklings

The physique of ducks directly affects the effect of brooding. The healthy ducklings have the same shell time, normal development, bright coat color, bright eyes, good abdominal contraction and strong struggle in the hands. Weak ducklings have dry feathers, nailed navel, large belly and navel, weak feet, overweight or underweight.

When ducklings are transported, each basket should contain 80-100 ducklings, covered with straw, or ducklings can be packed in cartons. Cover the cold weather with a thin cloth or a thicker cover. If you find the phenomenon of stacking ducklings, you should unplug them in time. Avoid sun and rain during transportation. To buy ducklings from a long distance, it is best to use the method of "purine eggs". In order to calculate the time of purine, it is most ideal for purine eggs to emerge just after they are transported to their destination.

Brooding mode

The method of raising chicks in cage. The size of the cage is 150 × 80 cm. The bottom of the net is 1 × 1 cm welded mesh or laminated plastic mesh, the edge net is 1.5 × 1.5 welded mesh, and the box body is erected with a 40-60 cm high bracket.

The method of raising chicks on the ground level. Clean the floor with quicklime, spread it with a cushion 8-12 cm thick, and form a 2-square-meter circle with a 60-cm-high bamboo ring.

Heating can use a variety of heat sources, in order to achieve the environmental temperature required by ducklings as the principle.

Brooding environment

1. Temperature: temperature is the key to brooding. The age of one week is 30-28 ℃, the age of two weeks is 28-26 ℃, and the age of three weeks is 26-24 ℃. It can be gradually transferred to normal temperature after three weeks of age. No matter in spring or summer, the temperature at night should be 1-2 ℃ higher than that during the day.

2. Humidity: the relative humidity during the rearing period should be kept at 60% Mel 65%. The humidity is too high and the feathers are moist, which affects the normal heat dissipation of ducklings. If the humidity is too low, it is easy to raise dust indoors, so that ducklings should suffer from respiratory diseases.

3. Ventilation: due to the ducklings' high body temperature, fast breathing, exuberant metabolism, and high room temperature, the air in the house is dirty, so attention should be paid to regular ventilation to make the air in the house fresh and clean.

4. Light: sufficient light can improve the vitality of ducklings, stimulate appetite, help digestion, and keep the house warm and dry. If the daytime light time is not enough, artificial lighting can be carried out. Day and night light should be provided in the 1-3-day-old rearing room.

5. Density: at the age of one week, 50 birds per square meter were raised in cages, 30-40 birds per square meter on the ground, and 40 and 25 birds at two weeks old, respectively. The survival rate of ducklings raised in small groups is higher. Generally, 60-100 feathers per group is suitable, which can be merged gradually with the increase of age, and raised in large groups.

Feeding and management of wild ducklings

1. Feeding and drinking water

Ducklings should drink water before eating. After the ducklings enter the nursery, they are first fed with 0.1% potassium permanganate water. Ducklings after long-distance transportation need to be fed with 5% cane enamel water, and the water temperature should be close to room temperature.

Before the ducklings enter the house, the floor of the nursery should be washed and disinfected with 10% lime water, and then disinfected with 1 ∶ 300 bacterial enemy spray. Indoor heating should be carried out 1-2 days in advance.

Soaked rice grains or formula feed can be used to start eating. Spread the feed evenly over the plastic sheeting to lure food. Attention should be paid to feeding less and adding frequently to prevent feed rancidity and deterioration from affecting palatability and nutritional value. The rats were fed 7-8 times a day at 1-week age and 6 times at 2-week-old, and then decreased gradually with the increase of age.

2. Training and releasing water

The weather is sunny and the outdoor ambient temperature is about 20 ℃. We should release water to the ducklings early so that the wild ducks can adapt to the domesticated ecological environment and enhance their physique. In summer, water can be released at the age of 1 week, and can be postponed to 2-3 weeks in spring and autumn.

Water release is carried out after eating. The first water release time is slightly shorter, generally 15-20 minutes, and then gradually increase the water release times and time. After releasing the water, let the ducklings dry their feathers on the grass, rest for a while and then rush back to the duck house.
