As the chicken ages, the temperature should slowly decrease. The temperature dropped to 28 degrees at the age of 2 weeks, and the stress was induced by a sudden change in the constant temperature after 1 week.
Second, the moisture level of the laying hens is slightly higher, especially for the Hyacinth chickens. Generally, the humidity should be controlled at 80%-75% in the first week, gradually decreasing as the age increases, and decreasing to 50%-60% in the later brooding period. .
Third, during the light broiler chicken, the light time should be gradually reduced. Generally, 24-hour light is used for 3 days so that the chicks have sufficient time to adapt to the environment and live independently as soon as possible to promote drinking and eating. Afterwards, light is reduced by 1 hour every day and light is kept constant for 12 hours after two weeks.
The light intensity, a large number of data has proved that chicks can grow well under low light, but to make it early and more of the intake, drinking water, light intensity can be greater.
The following illumination principles should be observed during brooding: 1. The illumination time should be short and not prolonged. 2. Regardless of the type of lighting system adopted, it should not be changed after implementation. It must not be ignored and the time of light must not be changed. The intensity of light must not be changed. 3. Keep the illumination in the house as even as possible.
Fourth, drinking new chicks should first drink water before eating. This is conducive to promoting intestinal peristalsis, absorption of residual egg yolk, elimination of meconium and increase appetite. Especially for long-distance transport of chicks, it can effectively supplement the moisture lost during transportation.
The first time drinking water should use cool water to 18-20 degrees of boiling water, water can add 8% glucose, while adding antibiotics, a variety of vitamins, electrolytes and so on.
First, the principle of feeding brooding feeding is a small number of times, that is, each time you add a small amount of feed, so that chickens eat within 3-5 minutes; eat and rest after 20-30 minutes and then add.
Chicks require high-energy, high-protein, vitamins. In addition, allicin can be added to both enhance appetite and enhance disease resistance.
In the breeding process, gravel can be added in an appropriate amount to enhance digestion. At the age of 1-2 weeks, each chick was fed 1 g per week with a particle size of 1-2 mm. At 3-7 weeks of age, each chick had 2 g for 1 week and had a particle size of mm.
Sixth, group rearing such as the use of three-dimensional online brooding, according to the growth of chickens, starting from the 3rd day of the selection. The weaker chicks are placed on the upper layer and are strong on the bottom. After stratification, they can be treated differently in terms of feeding amount, nutritional structure, etc., so that weak chicks can catch up as soon as possible to improve the evenness of the flock.
Grouping work should be carried out frequently, at least once a week, and individual adjustments should be made to improve the overall quality.
Second, ventilation and maintain a fresh air environment, is very important for the growth and development of chickens, so the construction of the brood must take into account the necessity of ventilation, reasonable design, and strengthen ventilation and ventilation.
The most irresistible in ventilation and ventilation is the thief wind, especially in the winter, the outside temperature is low, cold air enters the chicken house easily after causing some diseases. Therefore, to prevent the thief wind, it is important to adjust the position of the air inlet reasonably. In addition, it is necessary to place a heat source at the air inlet to preheat the cold air.
In general, the work of brood chickens is a comprehensive task. Apart from the above points, there are also links such as immunization, deafness, disease prevention and disinfection, and disinfection. Only the technical points in all aspects are carefully grasped, and various aspects are integrated. Sexual considerations can make a good job in brooding.
Feeding and management points for chicken brooding
The brooding house should be warmed up 2-3 days before picking up the chicken. When raising the temperature, attention should be paid to ventilation. After picking up the chicken, the temperature should generally increase by 0.5-1 degree. The suitable degree of the chickens in the book is 33-35 degrees, but it is practical. The middle school should be flexible according to the season, weather changes, and temperature. If the summer brooding, the humidity can be controlled between 33-34, the winter can be increased accordingly, generally 35-36 degrees is more appropriate. In addition, the temperature can be adjusted according to the state of the flock. If the youngster hides his neck, the “cockroach†will be called crowded to increase the heat source; if the chickens have wings, gasps, open their mouths, drink plenty of water, and are reluctant to eat, indicating that the temperature is too high, measures must be taken to slow down the temperature; when the temperature is normal, The chicks are spirited and lively, free of movement, evenly spread, and feeding normally.
