Suitable temperature for brooding broilers The suitable temperature for growth of chicks decreases with age. The brooder temperature is 35°C-34°C for 1-2 days, the brooding room temperature is 25°C-24°C, and the temperature for brooders is 3°-7 days. 34°C-31 °C, brooding chamber temperature 24 °C -22 °C; second brooding temperature 31 °C -29 °C, brooding chamber temperature 22 °C -21 °C; 3rd brooding temperature 29 °C -27 °C, brooding chamber temperature 21 °C - 19 °C; fourth week brooder temperature 27 °C -25 °C, brood chamber temperature 19 °C -18 °C. The temperature of the brooding room is lower than that of the brooding brooder, so that there is a certain temperature difference in the house. The chicks can freely choose the suitable temperature zone to facilitate the growth of the chicks; the brooding temperature must be kept stable and cannot be changed suddenly, otherwise the feed will not be raised again. Good can not raise chicks. Adjusting the temperature in time The above temperature is only used as a reference, and the application should be adjusted flexibly according to different conditions such as the brooding season, chick breed, and physical strength. Early winter and late spring need not be too high, but winter should be slightly higher in early spring; broiler chicken should be high, egg chicks can be slightly lower; when the outside temperature is high, the temperature of the brooder is slightly lower; when the weather is cold, it is slightly higher; Some youngsters are lower; electric heat insulation umbrellas are higher, coal insulation umbrellas are lower; there are diseases that are higher, and health is lower. The general insulation umbrella is accompanied by a temperature regulator to automatically adjust the temperature, but its performance should be checked at any time to ensure normal operation. For brooding umbrellas, the temperature should be turned down 1-2 times per week. If there is no temperature regulator, gradually increase the brooder, and gradually reduce the brooding temperature. If the coal furnace is used for heating, when a higher temperature is required, less coal shall be added and ground shall be used to make the furnace prosper for a long time. When the temperature needs to be low, a part of the furnace door may be sealed. The thermometer used for temperature measurement should be hung at the height of the chick's back in the brooding room. Don't get too close to heat, and don't put it in the wrong place. The appropriate temperature, in addition to the observation thermometer, can also be measured according to the activity of the chicks. Low outside temperature during the night chicks rest, the temperature of brooders should be 1 °C higher than during the day. Although thermometers can be used to check the temperature inside, the thermometer sometimes malfunctions. It is not sufficient to rely solely on the thermometer to judge the temperature. It is also necessary to determine whether the temperature is appropriate according to the dynamics of the chicks, especially when the chicks are observed at night. important. When the temperature is normal, the chicks are evenly distributed around the brooding temperature source, there is no obvious accumulation phenomenon, the sleeping state is stretched comfortably, the action is comfortable, the appetite is exuberant, the drinking water is normal, the sound of calling is light, and the feathers are smooth and bright. When the temperature is low, the chicks gather together near the source of the temperature or the corner of the wall, and squeak and squeezing each other, shrinking their necks and necks, feathers untidy, eyes half open and half closed, the body trembling, slow movement, poor appetite; temperature When they were high, the chickens were weak, far from the source of temperature, scattered, drinking lots of water, mouth breathing, poor appetite, and unruly feathers. According to the performance of the chicks, adjust the temperature in time. Observe that observing and preventing the daily observation of the pile-up keeper is one of the key measures to raise the chick's survival rate. In the winter and spring seasons, in particular, attention must be paid to observing the cold and hot conditions of the flock to prevent piles. Playing piles is a phenomenon in which chicks are closely packed together due to the cold, sometimes up to five or six layers, with a radius of several tens of centimeters. This is a common phenomenon in brooding. Chicks are not discharged due to normal metabolic heat production. The chicks are prone to overheating and being overly humid. There is a lack of air in the piles, causing the chicks to sweat, catch colds, have trouble breathing, and fainting. In severe cases, they will die in large numbers. When it is found that it is necessary to promptly squeak and dispel the chicks by hand during the playing process. This work is called rushing, and it is particularly important for the first three days of the brooding. In addition to rushing, the brooding temperature should be raised in time, blocking the tuyere outlet, creating a warm and comfortable brooding environment. Another effective method to prevent piles is to use the enclosure during the raising of the brooding, and to divide the chicks into several brooding stalls in a large brooding room. A warming umbrella is required to have a protective enclosure. The purpose is to prevent death due to low temperatures or the accumulation of chicks. If possible, it is better to be divided into small groups before and after hatching. It is better to have a small number of chicks with weak or irregular sizes. If there is not enough time for hatching, leave one or two empty circles when placing the newborn. When observing the chicks, take a part of the weak chicks and put them into the empty circle for raising. The weak, young, small circle should be at a high temperature in the brooding room as much as possible. Slow desuperheating should be done before the chicks are transferred to chickens. Take off gradually and take care not to cause drastic changes in the ambient temperature. At the beginning, it is possible to stop the temperature at night and daylight, and after 6-7 days, stop the temperature when the chicks gradually adapt to the natural temperature. The period of de-warmness is often the period when the chicks start moulting. At this time, unless attention is paid to increasing nutrition and supplementing vitamins, improper de-warming techniques can cause stagnation, indigestion, development, and severe death. The room temperature during the desuperheating period is preferably 20°C. Dealing with the relationship between insulation and ventilation In winter and spring, due to the need for insulation, the brooding room is relatively closed and the air is easily contaminated, affecting the health and growth of the chicks. If charcoal and coal are warmed in the brooding house, carbon dioxide and carbon monoxide are produced, which can cause poisoning and other phenomena. Ventilation and ventilation is an effective method for reducing harmful gases. Therefore, there should be ventilation equipment in the brooding room. The ratio of the ventilation window area to the brooding room area is 1:30, except for the ventilation equipment. In addition, it is advisable to use a cloth window for ventilation, so that when outside cold air flows into the room, it gradually warms up, and it can prevent the interior from having too much air.
