How to regulate the temperature and humidity of chick rearing?

The humidity of the brooding house should be indicated by a dry hygrometer, too high or too low is not suitable for the growth and development of chicks. The ideal humidity is 60%-70% for the first week and 55%-60% after the second week. If the humidity is too low, the dust and feathers in the house are flying, and the chicks are susceptible to respiratory diseases and feather underdevelopment; When the humidity is too high, the harmful gases increase, which is conducive to the survival of pathogenic microorganisms and the development of parasite eggs, and chicks are susceptible to various diseases.

It needs to be about 33 degrees, and the temperature needs to be lowered every week, so as to better ensure the temperature and ensure the humidity of the air.

To keep the temperature around 33 degrees, to drop slowly, to allow the chicks to have a phase of adaptation, so that it is fine.

Temperature is the primary condition for the normal growth and development of chicks, so how much temperature control is more suitable for chicks in 20 days?

It is more appropriate to live 20 days under 24 26. Newly hatched chicks are small, delicate, less downy, have low warmth, and are thermoregulated.

Imperfect, gradually improving after 3-4 weeks of age. Therefore, doing a good job of cold protection and heat preservation and adjusting the appropriate temperature and humidity is the key to raising chickens and improving the survival rate of chickens.

In order to observe temperature changes at any time, thermometers can be placed in the four corners and centers of the incubator.

to determine if the room temperature is balanced. Determine whether the temperature is suitable and spread it evenly and quietly on the mesh bed or futon. If they are huddled together, the temperature will be very low. If the chicken is loose in the mouth, the temperature is too high and needs to be adjusted.

When the young birds reach 15 to 20 days of age, their internal temperature control function gradually improves, and their body temperature can be kept at a constant temperature. If the insulation does not meet the requirements of the outside temperature, the chicks will not be able to grow properly and will not survive.

Newly hatched chicks still have unabsorbed yolks in their abdomen. Within 3-7 days after hatching, the nutrients they need mainly come from the remaining yolk. If the right temperature can be obtained, it can promote the absorption of the remaining egg yolk of the chicks, thereby enhancing the physique of the chicks and improving the survival rate.

Especially in the case of poor hatching and weak chicks, it is more advantageous to increase the brooding temperature.

As for the temperature of the brood, most people think that the temperature during the brooding period is important, especially the temperature can be slightly higher in the first three days. Depending on the season, climate, type of brooding, chicken constitution, etc. The temperature during the brooding period should be flexibly controlled.

For example, at night, when the outside temperature is low, the temperature of the chickens in a dormant state is higher than during the day1. The incubator temperature can be slightly lower when the outside temperature is high, and higher when the weather is cold. The weak young man grows taller; higher in the presence of disease; High in winter, low in summer.

There will be less rain.

Humidity, the humidity in the chicken coop should not be too high, should not exceed 60%, humidity is also an aspect that most farmers tend to ignore. The heat dissipation of the chicken mainly depends on the speed of breathing. If the humidity is too high and the temperature is too low, all the heat generated by the chicken will be absorbed by the moisture.

Low temperatures are not conducive to the growth of chicken feathers, making chickens susceptible to respiratory diseases.

Density, to ensure the normal growth of chickens, it is necessary to reasonably control the density, which has an important impact on the growth of chickens. Otherwise, chicks are prone to a stress response.

Increased incidence. In terms of light, it is also important to pay attention to light when feeding. The main purpose of light is to prolong the feeding time of chickens, increase feed intake, and promote the growth of chickens. Chickens can be irradiated with continuous or intermittent light.

It is most appropriate to control it at about 25, because the most important thing to do in the 20 days of birth is the protection of temperature.

In general, the temperature should be around 24 degrees to 26 degrees, and these chicks can be said to be in a state of growth at this time.

The temperature of the hatching chicks is optimal, and the humidity is between 65% and 70%. It depends on the breed and size of the eggs and the temperature in the environment. During the incubation process, the eggs should be turned at regular intervals to ensure that they are evenly heated.

The artificial incubation temperature of chickens is around the same level. However, depending on the size of the eggs, the breed and the ambient temperature and the performance of the machine, the ideal incubation temperature will vary to a certain extent, but the high will not exceed, and the low will not be lower than the incubation humidity: the importance of incubation humidity is mainly reflected in the hatching stage, and the relative humidity during hatching should not be less than 60%, so as to keep it between 65 and 70% is the best.

Higher humidity is conducive to chick pecking, and low humidity will cause sticky hairs and other phenomena, affecting hatching. The humidity in the incubation stage should be mastered by the principle of high before and then low, generally 60-55% before 6 days, and kept at about 50% after 6 days.

Humidity is one of the important conditions for successful incubation, and suitable incubation humidity can make the embryo evenly heated in the early stage and strengthen the heat dissipation in the later stage, which is not only conducive to embryo development, but also conducive to hatching.

1. Appropriate incubation humidity.

Relative humidity should be maintained at around 55% when eggs are set in batches and 65% to 70% at hatch. The humidity of the whole batch should be mastered by the principle of "high at both ends and low in the middle", the relative humidity in the early stage of incubation is 60% 65%, the relative humidity in the middle stage is 50% 55%, and the relative humidity in the later stage is 65% 70%.

2. High humidity and low humidity influence.

If the incubation humidity is too high, the normal evaporation of water in the egg will be blocked, and the fetal membrane and shell membrane will hinder the exchange of embryo gas due to excessive water content, affecting the normal development of the embryo. Therefore, when the humidity is too high during incubation, the hatched chicks are prone to abdominal distention, soft legs, many weak chicks, lack of energy, and low survival rate. When the incubation humidity is low, the evaporation of water in the egg is accelerated, and the embryo is easy to adhere to the shell membrane, so that the hatched chicks are prone to small, thin, scorched feathers, and high mortality.

When eggs hatch, too much humidity and too little humidity can have a negative impact on hatchability and chick health. Therefore, high temperature and high humidity and high temperature and low humidity should be strictly prevented. Whether the incubation humidity is normal can be measured by a wet and dry bulb thermometer, and can also be judged according to the size of the egg air chamber, the amount of weight loss and the peck of the hatch.

When the humidity is suitable, the chick pecks the shell along the maximum diameter of the embryonic egg.

1. Temperature. Chickens are sensitive animals, especially for temperature, so breeding broilers must provide the chickens with a suitable temperature, pay attention to the temperature to be balanced, whether it is day or night, the temperature can not be high or low, easy to cause diseases. At the beginning of brooding, the temperature is maintained at 33-35 degrees Celsius, and the temperature index gradually decreases over time.

Generally, it drops once in three days, and the winter time can be a little longer, until it drops to about 22 degrees, and the specific temperature should be adjusted according to the situation of the chickens, and the data is just a reference.

2. Humidity. Overall, humidity does not have a more direct impact on the flock than temperature, and the harm is not as great as that of temperature. But temperature and humidity go hand in hand, and the amount of humidity affects the flock's need for temperature.

If the humidity is too high or too low, the effects are also significant. It is recommended that the humidity be controlled at 65-70% in the first week, 60-65% in the second week, 55-60% in the third week, and then stabilize at 55%.

1. The humidity is too high.

The humidity of the chicken house is too high, which is conducive to the reproduction of various bacteria and pathogenic microorganisms, and accelerates the occurrence and development of various diseases. Summer is also not conducive to heat dissipation, heat stress, etc. If the humidity is too high, the humidity in the house can be adjusted by heating and ventilation, and the ventilation must pay attention to the constant temperature during the brooding period.

2. The humidity is too low.

If the humidity is too low, it will cause dryness and increased dust in the chicken house, which can easily cause respiratory diseases and E. coli. In a dry environment, it is also easy to dehydrate the flock, affecting the normal metabolism of the flock. If the humidity is too low during the brooding period, it can also cause gout in chicks.

If the humidity is too low, you can increase the humidity by spraying and disinfecting, disinfecting with chickens, sprinkling water on the floor and wall of the chicken coop.

<> temperature, humidity and daylighting are important factors in flock management, and improper management will cause losses to flocks. Let's talk about the temperature and humidity and lighting requirements of brooding chicks for reference.

The first day of brooding chickens requires the temperature in the house to be 35 37, and then it drops every day to 18 19, which is kept constant, and when the temperature is too high, it is easy to lead to dehydration of chicks, increase the mortality rate, and reduce the uniformity of the flock; When the temperature is too low, the chicks are susceptible to disease, mortality increases, growth rates are slowed down, and uniform skin decreases.

Humidity management is particularly important in the first week of brooding, and it is also the most difficult stage to control, due to the high temperature requirements of brooding, the chicks have less manure, and often pretend to be too low. Methods of humidification include sprinkling water on the scaffolding and floor, spraying and disinfecting chickens (only using water before and after immunization), etc.

In the 3 5 days after coccidiosis vaccination, humidity should be added to the scaffolding to ensure the immunization effect, and it is recommended that the relative humidity of the air be maintained at 55 60.

Strictly implement the light plan during the brooding period, adjust the time relay (or timing clock), and replace the broken bulb in time to ensure that the light is uniform and the intensity is appropriate. After 1 week of age, a 60-watt bulb can be replaced locally during immunization to ensure that the immunization operation can be seen clearly, and the original bulb can be changed back immediately after the operation is completed.

Intermittent ventilation can be implemented during the first week of brooding. When the temperature outside the house is close to or exceeds the temperature inside the house, the exhaust fan can be turned on for a short time for ventilation. If the air in the house is too noisy and dirty, consider turning on the hovering fan for 5 to 10 minutes intermittently (every 20 to 30 minutes) in the middle of the afternoon.

After a week, start ventilation and increase the number and time of turning on the exhaust fans, but take into account the temperature, humidity and air pollution in the room. The airflow generated during ventilation should not be directly directed at the chickens, and the use of regular temperature control ventilation equipment should be adjusted and maintained.

<> temperature is very important for chick thermoregulation, exercise, feeding, drinking water and feed utilization, etc., so temperature is the key to the success or failure of brooding, and it must be mastered appropriately. Let's take a look at what is the right temperature for chick rearing and how to raise chicks well.

Normally, during the brooding period, the suitable temperature of the brooding room is: 1-2 days old, the temperature is 35, 3-7 days old, 32-35; 7-14 days old, 29-32 ; 14-21 days old, temperature 27-29; After 22 days of age, the temperature is 21. Of course, the appropriate brooding temperature and filial piety degree is different due to the different ways, seasons, brooders and varieties of brooding, so the above data is for reference only.

Ambient temperature is the key to raising chicks, especially for chicks transported over long distances, temperature is crucial, otherwise cold or dehydration will return to the stove, reducing the survival rate. So, the principle of general warmth:

high in the early stage and low in the later stage; High in small groups, low in large groups; Weak chicks are high, healthy chicks are low; High on cloudy days and low on sunny days; low during the day and high at night; high in winter and low in summer; Broiler chickens are high, breeders are low.

In short, it is necessary to grasp the temperature according to the mental state of the chicks, that is, the chicks are not piled up, evenly distributed, lively, and stretch their legs. If the chicks are piled up, chirping, close to the heat source, etc., it means that the temperature is low; If the chicks stay away from the heat source and drink desperately, the temperature is high.

1) Seed selection is related to the selection of varieties with a breeding and promotion system, and can be introduced nearby.

2) Chick selection According to the hatching time, select chicks with breed characteristics, lively and robust.

3) Group off according to the specific situation, different varieties, strength and weakness, regular grouping.

4) Open food off Chicks start feeding 24 to 36 hours after hatching. Drink water first, then start eating, or start eating and drinking at the same time. In the first ten days, it is best to add 3 5 sugar water or 5 glucose and vitamin C to the drinking water to promote the absorption of egg yolk.

5) density off the density in winter is large, the density in summer is small, and the density is determined according to the different chick breeds and feeding methods.

6) Ventilation is closed, especially for cage chickens, the feeding density is large, and it is necessary to pay attention to the timely discharge of harmful gases and the speed of air convection. The open brooding room can be ventilated regularly by opening doors and windows at appropriate times; The closed brooding room needs to use a fan and longitudinal ventilation to meet the requirements of fresh air.
