Breeding techniques of Hot Duck

The breeding of hot ducks is carried out by artificial hatching. first of all, we should do a good job in selecting eggs.

Selection of breeding eggs

We should choose non-ruptured, odorless and non-spoiled duck eggs as breeding eggs. after they are selected, they are placed on the grid, and after they are placed, they are put directly into the incubator, and then disinfection is carried out.

Disinfection

Disinfection can choose Jiantawei sprinkling disinfectant (patted medicine), mix it into 600 times the dilute liquid, spray directly on the eggs, and so on after the eggs dry, we can just go to the door of the incubator to manage the incubation period.

Management of incubation period

The whole incubation process takes about 40 days, with the first 27 days in the incubator and the last ten days in the incubator bed. The specific methods are as follows:

1. Embryo movement can not only make the embryo heated evenly, but also effectively prevent the embryo from adhering to the eggshell. There are two ways to turn eggs, the first is to take the net frame out of the incubator and flip it individually, and the manual operation must be careful to reduce the eggshell damage rate to a minimum; the second is to rotate as a whole, by pushing and pulling the hatching grid, so that the position of the breeding eggs changes with it, and these two methods can be carried out alternately.

2. Light eggs: during the incubation period, the light eggs should be carried out on the 7th, 13th and 23rd days respectively. According to the eggs can be carried out with light, there are two purposes, one is to see the hatching of breeding eggs; the second is to pick out spoiled azoospermic eggs and dead eggs. Shooting eggs can be carried out at night or during the day, and if it is a novice, it is recommended to do this work at night, because in a dark environment, if there are broken ones, it is easier to distinguish them from the color, and for those whose colors are gray, we have to pick them out in time. Moreover, according to the egg, the development in the breeding egg can be found very obviously. in about 7 days, you can see something like a silk mesh inside, and in about 13 days, it will become a cotton-shaped object, that is, the duck larva that is slowly hatching. At about 23 days, the breeding egg will look like a cloud, and a piece of black and white, this is the larva about to take shape.

3. Egg drying: in the process of hatching, there are eleven very important steps to help the embryo dissipate heat and breathe fresh air. Because duck eggs contain more fat, with the development of the embryo will lead to an increase in calories, if the temperature is not adjusted properly, it is easy to cause death. Therefore, we have to open the door of the incubator once a day in the morning, noon and evening to dry eggs for about 2 hours each time. This can play a role in regulating air circulation to ensure the smooth progress of hatching.

4. Temperature control: during the incubation period, the temperature must be strictly grasped in order to ensure the success of the incubation. In the first 7 days, we will keep the temperature at 38 ℃. After 7 days, we will keep the temperature at 37.8 ℃. After 23 days, we will lower the temperature to 37.4 ℃. We can adjust the temperature through the machine, or we can use manual coordination, such as egg adjustment, egg adjustment is to change the upper and lower positions of the net frame, and the temperature in different positions in the cage is also different, so that the temperature can be balanced.

5. Humidity control: during the incubation of duck eggs, the water in the eggs will continue to evaporate, so the weight of the eggs will also be reduced. We had better take measures to control the weight loss of duck eggs at about 13%. The main control method is to maintain humidity. In the early stage, relatively high humidity can avoid excessive evaporation of water in the eggs; in the middle stage, breeding eggs need to remove more water and require relatively low humidity; in the later stage, the humidity should be increased to facilitate the hatching of ducklings. To adjust humidity, we usually use sprinkling water. We have to sprinkle water once a day. What we need to pay attention to is that the water temperature must be controlled at about 38 degrees Celsius, warm water should be evenly sprinkled on the eggs in the incubator, and the shelf in the incubator should be turned when sprinkling water, so that every duck egg can be moisturized by moisture. After sprinkling, the door of the incubator is opened first. It takes 5 minutes for the door to be closed.

About 27 days later, you can move out of the incubator and put it on the incubator bed. Here, we can provide you with a tip. We can take a small piece of sand net and put it in the middle of the two racks. Note that the above one cannot hold the eggs, and then change the positions of the two cages up and down. It is easy to collect the breeding eggs into the net, and then put the breeding eggs on the incubator bed.

Management during the incubator period

During this period, it takes about 15 days to manage the main body temperature control and check the spoiled eggs.

1. Adjust the temperature: we need to control the temperature at 36 ℃-37 ℃. The eggs on the incubator can dissipate heat spontaneously. The more close to the middle, the higher the temperature will be, while the temperature around will be relatively low, so it is not conducive to hatching. Therefore, we have to turn the eggs every 4 hours. The method is to put the eggs in the middle and squeeze them down gently. In this way, the eggs in the middle can be pushed to the side, and in this way, the temperature can be well balanced.

In addition, when the temperature is too high, we can turn on the fan to lower the indoor temperature, and we can also sprinkle water on the incubator bed. The temperature should not be too low, with 18 ℃-26 ℃. When the temperature is too low, we can use blankets or cotton cloth to warm up.

2. Inspection: the more we get to this last moment, the more we have to check it out. There are three ways, as the saying goes, "one look, two smells, three listens". This is to look carefully and find that the color of the skin is dark, the hands feel cold, or the tip of the egg is black, which is a dead embryo. Next, smell it with your nose. If the breeding egg stinks, it must be broken. If you are not sure, hold the breeding egg in your hand and gently shake it in your ear. If you hear the sound of liquid sloshing, it must be a failure of incubation. You can throw it away.

About 7 days later, you can see a small hole in the duck egg, which is the hole pecked out by the ducklings, because they want to get out of the shell, and on the 13th day or so, they can't wait to get out of the eggshell.

Vaccination

Three hours after the duckling comes out of its shell, we need to vaccinate them immediately. The vaccine can be vaccinated with Muscovy duck parvovirus vaccine (photographed). Usually, when injected, the injection should be injected from the back of the neck of the duckling. The dose is 0.2 ml per duckling. After the vaccine injection is completed, it will enter the growth stage of raising ducklings.

Here, I would also like to remind you that at present, most breeding grounds do not have the technology to hatch, and they all rely on the purchase of duck seedlings for breeding.
