Controlling the temperature of the chicks in the conservation process

1 temperature requirements

Chicks grow to 15 to 20 days, the body temperature control function development gradually improved, then in order to maintain a constant body temperature in the state, if before holding facilities reach the outside temperature requirements chicks, chicks can not grow normally , but also difficult to survive. Newly hatched chicks, abdomen still remained not been absorbed yolk, in hatched 3 to 7 days, the required nutrients mainly from these remaining egg yolk. If chicks get a suitable temperature, it will help absorb the remaining egg yolk, thereby enhancing chicks physique, improve the survival rate, especially in the poor and the weak young hatch more, raising the temperature of the brood is more beneficial. 2 good insulation work Temperature on brood, most think the temperature in the first week of the child's most important, especially in the first three days the temperature can be set slightly higher too. Temperature control during brood should be with the seasons, climate, brooder species, chicks, etc. physical flexibility. For example, the outside temperature is low at night, when the chicks restful sleep brooder temperature should increase 1 ℃ than during the day; when the outside temperature is high, the temperature may be slightly more brooding, cold weather slightly higher; more weak young should be higher; there disease should be higher; winter should be higher, summer should be lower; rainy days should be higher, sunny day should be lower. When using nanny brood umbrella, umbrella internal temperature of the first week is 35 ~ 32 ℃. Chenet away from heat sources should be maintained at 26 ~ 21 ℃ appropriate. Temperature should be away from the edge of the nanny umbrella litter 5 cm height, measured Sherwin thermometer should be hung on the nanny umbrella farther away from the wall, one meter above the litter. With the growth of weeks, the brooding temperature can drop 3 ℃ per week is adjusted until the same umbrella warm up with Sherwin. During the entire brood, you must give the chicks to create a smooth, proper, gradual transition of ambient temperature, avoid temperature fluctuated. Nanny umbrella are generally accompanied by a temperature regulator. To ensure their normal work, before rearing chicks, check its performance. During the brood, although each requires a suitable temperature range weeks are clear, discounted another thermometer indicates, but because the thermometer can sometimes malfunction, coupled with the flock itself changing situation and environment, and therefore entirely dependent on the thermometer to determine the brood of use the correct temperature is not enough, it should also be based on the dynamic chicks to determine whether appropriate with warm, especially to observe the sleep state. When the temperature is appropriate, chicks lively spirit, a good appetite, night spread evenly in the brooder, showing around a heat source, stretch the body, head and neck straight, appressed to the ground asleep, no specific state and disturbing sounds, sheds extremely be quiet. Temperature is low, the chicks together or near a heat source, did not dare to come out when feeding chickens feed. Temperature is high, the chicks away from heat, mouth breathing, drink lots of water, feet, mouth redness. From the first weeks of brood from the application of bamboo or reed mat, etc. made of 45 to 50 cm high fence write, along nanny umbrella around the fenced to prevent newly hatched chicks away from heat and cold do not know return, make the limitations In holding area, easy feed and water. The distance between the edge of the fence with the nanny umbrella, usually 90 cm in summer, winter is 70 cm. Chicks to be accustomed to the heat source, after a warm, you can gradually expand the scope of the fence outward, so that the chicks have bigger venues. Usually in 3 days began to expand, to 6-9 days can be dismantled fence. The use of other heat sources, but also to the heat source as the center, appropriately fenced chicks, especially at the corners of houses, use the edge fence surrounded by a wall, eliminating dead ends, avoid crowded heap pressure chickens died at the corners. When homes outside temperature is low, discounted waste heat from the heat source and impossible to brood discounted maintain a sufficiently high temperature, leaving the chicks feel uncomfortable when, can be close to the outer edge of the fence, plastic hanging from the ceiling near film curtain vertical approach close to the ground, buildings area will be used during the interval small chicks can also be placed in the middle of the house heat, so both ends of the blank. This reduces the brood space, can raise the temperature of local space, and reduces fuel consumption. He stressed insulation, air circulation must not be ignored, but also to keep the indoor air fresh. Breeders may feel of measurement when entering the house smell the pungent odor of ammonia odor or strong carbonate, it should open doors and windows to replace the air, but can not make the cold wind blowing directly chicks who should make the wind slowed down by various barriers flow rate, with particular attention to those places and door chicks infrequent events, the window to check for leakage. Check for the determination, if leakage can feel the cold wind blowing. Where leakage must be promptly blocked to prevent the chicks colds and other respiratory disorders. 3 good work off temperature Young chicks into the front, but also make the work of the late off temperature. The so-called off temperature is gradually stop heating. Spring brood, a month or so off temperature; summer brood, as long as the morning and evening warmed 4 to 5 days you can take off warm; fall brood, usually about two weeks off temperature; warm winter brood off later, at least 45 days. Especially in the cold season, the house relatively poor thermal insulation properties, to appropriately raise Sherwin, thick bedding through the stove or heating, but heating does not have to be too high, as long as the chicken is not curled up on it because of the cold. Off when the temperature needs to gradually lower the temperature, initially during the day to warm, to warm at night, after 5 to 7 days after the chicks grow accustomed to natural Sherwin, then completely without heating. The temperature should not drop too fast, sudden changes in temperature are likely to cause respiratory young Naruto.
