Temperature control is an important technical link of brooding and the key to the success of brooding. Ducklings are not well-developed in their physiological systems, and are prone to poor body temperature regulation. They are afraid of both cold and heat. Therefore, the brooding room requires good insulation and a quiet environment.
The duck house should be pre-warmed in advance to prevent the temperature of the ducklings from reaching the standard before the arrival of the chicks (in the summer, it can be determined according to the situation). The first day of the chicks should be controlled at 33 ℃ ~ 35 ℃, and the temperature can be reduced by 0.5 every day. ℃ adjustment, can also adjust the temperature once every 3 to 5 days, each time 2 ℃ ~ 3 ℃. Strictly adjust the temperature balance in the house, and always keep the temperature in the house (breding section) the same before and after. If necessary, you can turn on the fan to adjust the temperature to maintain the heating balance. In hot conditions, the brooding temperature can be appropriately lower than the standard; in cold cases, the brooding temperature can be appropriately higher than the standard. Two weeks, the inner side is more important than insulation, and two weeks later, the focus is on ventilation. To grasp the most suitable points for temperature requirements of ducks, attention should be paid to the distribution of ducks. When the temperature is too high, the ducks will be far away from the heat source and tend to the water source; when the temperature is too low, the ducks will shrink neck, get together and get close to the heat source; when the temperature is appropriate, the ducks will be evenly distributed throughout the brooding circle, and the mental state is good Active activities. In addition, the fence should be made of non-ventilated material to protect the ducklings from the thief wind.
When the outside temperature is low, especially in rainy (snow) weather, the temperature in the brooding house is higher; when the outside temperature is high, the temperature in the brooding house is lower; the temperature of the weak ducklings is higher, and the constitution is good The temperature can be appropriately lower. Feeding practice has proven that the first three days of brooding are to use high-temperature brooding at a temperature of 34 ° C to 35 ° C, which is conducive to the absorption of yolk and reduce the occurrence of duck pupae. After 1 week, the temperature dropped by 2 ° C ~ 3 ° C every week, and by the fourth week it dropped to 21 ° C ~ 24 ° C. If the temperature does not drop or falls too slowly, it is not conducive to the growth of the feathers. It is not enough to cool down too quickly. The ducklings do not adapt, the growth is slowed, and the death increases.
In order to better grasp the temperature situation, a thermometer should be hung inside and outside the duck house. The thermometer should be located above the duck's back. Experienced breeders often determine whether the temperature is appropriate based on the performance of the ducks. When the temperature is appropriate, the ducklings are evenly distributed, lively and smooth, the feathers are smooth and neat, and the appetite is strong. Slow movements, constricted necks, restless sleep, focus on heat sources, squeeze each other, eyes half open and half closed, body trembling, making awful noises; when the temperature is too high, ducklings stay away from heat sources, drinking water increases, and appetite decreases He stretched his neck and opened his mouth to breathe, his breathing accelerated, his irritability, and his feathers soaked in sweat. During the brooding period, in order to avoid sudden temperature changes at night and affect the survival rate of ducks, the temperature must always be observed without leaving the human body. In addition, the brooding house should be protected from thieves. When the duck house has a thief wind, the temperature on one side decreases, and the ducks will avoid one direction and run to the other side at the same time.
Special attention should be paid to gas poisoning during brooding, especially in the first week of ducklings. Due to high temperature requirements, closed doors and windows, and poor ventilation, gas poisoning occurs from time to time. Gas poisoning can cause people to feel dizzy and severely weak limbs. Ducklings show drowsiness, feed intake and water consumption decline. The key to preventing gas poisoning in ducklings is to install a chimney in the stove in the house, and pay attention to ventilation.
In addition, because the ducklings are highly grouped, even when the brooding temperature is appropriate, the ducklings often pile up and sleep while resting. If the brooding temperature is low, the stacking will be more serious, and it is easy to crush and hurt the ducklings. Therefore, the situation of ducklings must be observed frequently, and there is a pile-up phenomenon, and they should be driven away immediately, and the grouping and temperature of the brooding room should be appropriately increased to reduce the death of ducklings and improve the survival rate.
