Efficient duck breeding technology

The quality of breeding ducks directly affects the growth rate, physical size and laying performance of offspring.

Appearance is an important feature of a variety and the main basis of productivity. Therefore, the selected breeding duck must have the inherent characteristics of the breed, and at the same time, attention should be paid to the choice of economic types.

2. Proportion of male and female ducks

If the cross method is adopted, the combination method is generally adopted. But the ratio of male to female must be appropriate, too many drakes or too few drakes will affect the fertilization rate. The male-female ratio is roughly as follows:

Meat duck1:4 ~ 8; Dual-purpose duck1:8 ~12; Laying duck 1: 20 ~ 25.

3. Service life

Breeding ducks are usually replaced once every two to three years, because the egg production is the highest in the first year, and it drops 10 ~ 15% in the second year and 15 ~ 25% in the third year. The egg production of ducks over three years is obviously reduced, the ducklings are stunted and the mortality rate is high. So, in the fourth year, the ducks. The service life of meat ducks is shorter than that of eggs, and they will be eliminated in three years.

The breeding period of laying ducks is generally 2-3 years. Breeding drakes for meat are generally 1 ~ 2 years old.

4. Choose a good grazing place

Before the seedlings turn green in early spring, the mother ducks are herded in ponds and rivers to feed on fish, shrimp, loach and aquatic organisms. Once ploughed in spring, the green manure field where seedlings are sown can be prepared for grazing after ploughing. There are more natural feeds such as grass seeds, grass roots, earthworms and insects in this land for the mother ducks to eat. Paddy fields planted with seedlings are not suitable for grazing because of chemical fertilizers or pesticides.

5, careful grazing

The temperature is low in early spring, so it is advisable to graze late and return early, and extend the grazing time day by day. Pay attention to the water temperature when grazing, and enter the water and go uphill slowly to avoid hurting the duck's paw. When grazing in the river network area, it is necessary to go upstream. At this time, you have enough physical strength to catch more food. In windy weather, it is necessary to graze against the wind, and properly control the walking speed of ducks to avoid the wind lifting their feathers and making them catch cold.

In the coming year, the mother duck will lie prone after eating because of her large size and slow movement, which will easily accumulate fat and affect her laying. So we should control them, let them move as much as possible, and increase the amount of exercise. Laying ducks are timid and easily frightened, and the grazing route should not be changed too suddenly every time. Male ducks have a strong sexual desire in the laying season, so we should pay attention to the ratio of male ducks to female ducks to avoid duck riots and affect the laying of female ducks.

6. Feed in time.

During the laying period, the mother duck has a strong laying intensity, and the daily grazing and swimming are also large. The live feed and green feed they eat are large in size but low in nutritional concentration, so it is generally difficult to meet the nutritional needs of laying eggs. Therefore, the supplement of feed should be based on the number of eggs laid by ducks every day and the feeding status of ducks. When the temperature is low, energy feed such as grain should be properly supplemented to enhance the cold resistance of female ducks.
