Temperature control is an important technical aspect of brooding and is the key to the success or failure of brooding. Ducklings are not well developed in their physiological systems and are prone to poor body temperature regulation. They are both cold and heat-fighting. Therefore, the brooding room requires good insulation and a quiet environment.
Before the hatching, ducklings should be pre-heated in advance to prevent the temperature of the ducklings from reaching the standard before the arrival of ducklings (it can be determined by themselves in summer). The first day of the chickling is controlled at 33°C~35°C, and then it can be reduced by 0.5% each day. °C adjustment, but also 3 days to 5 days thermostat once every 2 °C ~ 3 °C. Strictly adjust the temperature balance in the house, keep the temperature in the house (broiler section) at all times basically consistent, and if necessary, open the fan and adjust it to keep the heat balance. In hot conditions, the brooding temperature can be appropriately lower than the standard; in cold conditions, the brooding temperature can be appropriately higher than the standard. In two weeks, the inside is heavier than the insulation, and after two weeks, it focuses on ventilation. To understand the optimum point of the temperature requirement of ducks, attention should be paid to observe the distribution of ducks. When the temperature is too high, the ducklings will stay away from heat sources and tend towards the water source. When the temperature is too low, the ducks will shrink their necks, get together, and be close to the heat source. When the temperature is appropriate, the ducks will be evenly dispersed throughout the brooding circle and have a good mental state. Active activities. In addition, the stalls should be made of non-ventilated materials to protect the ducklings from being affected by thieves.
When the outside temperature is low, especially in rainy (snow) weather, the temperature in the brooding room is higher; when the outside temperature is high, the temperature of the brooding room is lower; the temperature of the weaker ducklings is higher and the physique is better. The temperature can be appropriately lower. Breeding practice has proved that the first three days of brooding use high temperature brooding, the temperature of 34 °C ~ 35 °C, which is conducive to the absorption of yolk, ducklings to reduce the occurrence of white feathers. After 1 week, the temperature dropped by 2°C~3°C every week, and fell to 21°C~24°C by the fourth week. The temperature does not fall or is too slow to slow down the growth of feathers, and the cooling rate is too fast. Ducklings do not adapt, growth slows, and death increases.
In order to better grasp the temperature, the inside and outside of the duck house should be hung with thermometers. The thermometer should be located above the duck back. Experienced breeders often determine whether the temperature is appropriate according to the performance of the duck group. When the temperature is suitable, the ducklings are evenly distributed, lively and lively, the feathers are smooth and tidy, the appetite is exuberant, the ducklings spread their wings and stretch their legs, they sleep quietly at night, and they sleep comfortably and spread evenly throughout the duck house. When the temperature is low, the performance of the ducklings is low. Slow action, necking, sleep disturbed, focused on heat sources, squeezed each other, half closed eyes, body trembling, issued a tragic sound; when the temperature is too high, the ducklings away from heat, drinking water increased significantly, reduced appetite , Extend your neck and gasp your mouth, breathe faster, become restless, and your body feathers are sweaty. During the brooding period, in order to avoid sudden temperature changes at night and affect the survival rate of ducks, we must always observe and maintain the temperature. In addition, the brooding house must prevent the thief. When there is a thief in the duck house, the temperature on one side decreases, and the duck group will avoid one direction at the same time and run to the other side.
During brooding, special attention should be paid to gas poisoning. Especially during the first week of the ducklings, due to high temperature requirements, doors and windows are closed tightly, and poor ventilation causes gas poisoning. Occurrence of gas poisoning is dizziness, and severe limb weakness. The ducklings show drowsiness, and the feed intake and the amount of drinking water are reduced. The key to preventing duck gas poisoning is to install a chimney in the stove in the duck house and pay attention to ventilation.
In addition, due to the strong gregariousness of the ducklings, even if the brooding temperature is appropriate, the ducklings often sleep on piles during rest. If the brooding temperature is low, the pile will be even more severe and it will be easy to kill and injure the ducklings. Therefore, we must always observe the situation of ducklings and find that there is a heap phenomenon, and immediately drive it away, and appropriate grouping and raising the temperature of the brooding room so as to reduce the death of ducklings and increase the survival rate.
