How old are chicks to be? What is the right chick temperature?

Chicks: Newly hatched chickens. 0-50 days for chicks.

There is enough yolk in the chick just out of the shell, and some nutrients can be supplied to the chick within 3 5 days, and timely eating helps the chick to absorb the egg yolk in the abdomen, which is conducive to the discharge of meconium and promotes its growth and development, which is an important part of the brooding work. Eating too early will cause damage to the fragile digestive organs, and eating too late will consume physical strength and nutrients, which is not conducive to the growth and development of chicks. Chicks are usually fed 12 hours to 24 hours after hatching, and the mortality rate is lowest during this period.

Chicks can start eating, after the chicks drink enough water for 3 hours, once 6-7 percent of the chicks can move around at will, half of the chicks in the flock have pecking behavior when the food is appropriate.

Among laying hens, it is divided as follows: 1-day-old chicks to the beginning of production (usually refers to 0-20 weeks old) chickens are called reserve chickens (this period is also called the growth stage). Depending on the environmental conditions and nutritional needs of the chickens, the replacement chicks can be divided into two or three stages.

The two stages are divided into young chicks (0-6 weeks old) and finishers (7-20 weeks old): the three stages are divided into young chicks (0-6 weeks old), middle chicks (7-14 weeks old) and large chicks (15-20 weeks old).

Poor thermoregulation ability of newborn chicks The body temperature of newborn chicks is slightly low, about, the lowest can reach 33, and after 10 days, the thermoregulation system tends to be perfected and maintains the level of 41 42. Therefore, chicks at 1 week of age require an ambient temperature of 30 34, 25 30 at 2 weeks of age, and 20 25 at 3 weeks of age

Freshly raised pig's head.

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 varies depending on the brooding method, season, brooding device and breed.

Ambient temperature is the key to raising chicks well, especially for chicks that are transported long distances, temperature is crucial, otherwise cold or dehydration will reduce 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.

Summary. Chicks refer to 0 42-day-old chicks, because chicks have poor body temperature regulation ability, weak cold resistance, small gastrointestinal tract volume of chicks, digestive function is not yet perfect, poor digestion of food, poor disease resistance, and fast growth and development, extremely high metabolic rate, in addition to requiring adequate nutrition, but also to ensure that various environmental conditions are good.

Three-stage division method 0 6 weeks old chicks; 7 14 weeks old called chicks; 15 20 weeks old is called a chick.

That is, chickens that are around 100 to 140 days old belong to large chicks.

Summary. You can tell the age of a chick by:1

Assuming that incubation is generally about 21 days, when the first day after hatching, the chicks are 1 day old; The next day is 2 days old, and so on. 2.The age of the chicks can be judged based on their size and feathers.

Newborn chicks are small and appear fragile; At 2-3 days of age, small feathers begin to grow; 5-7 days of age grow more feathers; When they are more than 10 days old, they already have rudimentary wings. 3.Their age is determined by looking at their food and water intake.

Generally speaking, as the chicks grow, the demand increases. Therefore, the age of each chick can be inferred by checking their consumption of food and water. It is important to note that there is a difference in the growth rate of each chick, so judging by the above method alone can sometimes lead to errors.

The most accurate method is to calculate the eggs in sequence according to the hatching date.

<>1. Poor body temperature regulation ability of chicks: the body temperature of chicks is lower than that of adult chickens3, and their fluff is sparse and short, the skin is thin, the subcutaneous fat is less, and the heat preservation ability is poor, and they are afraid of both cold and heat. 2. Small gastrointestinal volume and poor digestion ability

Chicks have small digestive organs, limited food storage, and poor digestion, but chicks have vigorous metabolism and rapid growth and development. 3. Fast feather growth: Chicks have high requirements for protein in the diet, especially the level of sulfur-containing amino acids.

4. Strong sensitivity and poor disease resistance: chicks are timid and frightened, like to swarm, and all kinds of fright and environmental changes will cause stress reactions, thereby affecting growth.

First, the physiological characteristics of chicks

1. Chicks have poor body temperature regulation ability.

1) The body temperature of chicks is about 3 °C lower than that of adult chickens, and their fluff is relatively short, thin, less subcutaneous fat, and poor heat preservation, and they are afraid of both cold and heat.

2) Therefore, in the process of brooding, it must be provided with a suitable temperature environment, not too high or too low.

2. Small gastrointestinal volume and poor digestion ability

1) The volume of the digestive organs of chicks is relatively small, the storage of food is limited, and the digestion ability is very poor, but the metabolism of chicks is relatively vigorous and grows rapidly.

2) Therefore, the diet of chicks must be nutritious, comprehensive, palatable, and easy to digest.

3. Feathers grow fast.

Chicks have very high requirements for the level of protein in their diets, especially sulphur-containing amino acids.

4. Strong sensitivity and poor disease resistance.

1) Chicks are more timid and frightened, like to swarm, all kinds of fright and environmental changes will lead to their stress response, which will affect growth, and even startle, squeeze or die.

2) Therefore, when brooding, we must create a quiet environment for them, take good care, conscientiously do a good job in environmental sanitation, and do a good job in epidemic prevention.

3) Young chicks may become ill due to their poor adaptability to the outside world and their resistance to various diseases, and they may become ill if they are slightly negligent in feeding management.

2. What size of the chicken refers to the chick

1. Chicks generally refer to chicks aged 0-50 days. Chickens should be fed sand every 2 days or so after 10 days of hatching, and 3-5 times in a row. Generally, at this stage, the internal organs of the chicks have developed perfectly, and they can not only be fed with rice, but also with raw rice for forest feeding.

If you want the digestive organs of chicks to develop faster and better, you can add vitamins, trace elements and minerals to their feed.

2. When raising chicks, it should be noted that in addition to heat preservation, we should also pay attention to controlling humidity, and the incubator and hatchery must maintain appropriate humidity, so as to ensure the normal development of embryos. If the humidity is too large, it will prevent the normal evaporation of water in the egg, affecting the development of the embryo, and the hatched chicks are not easy to survive, and the relative humidity in the general hatchery room must be kept at about 60%.

3. If the wings of the chick droop, and there is a phenomenon such as panting, flapping wings to grab water to drink, making a chirping sound, and screaming very high, it is generally caused by too high temperature. When the temperature is suitable, the chicks are evenly distributed, the activity and eating are normal, the feathers are smooth and bright, the feces are strip-like after defecation, and the head and neck are straight during sleep.

Answer]: C According to the physiological characteristics of chickens and from the Fang Chun chain feeding management, the chickens of 0 20 weeks of grandchildren are divided into two stages: 0 6 weeks old and 7 20 weeks old, 0 6 weeks old chickens are called chicks, and 7 20 weeks old chickens are called early age chickens. Therefore, C.
