Brooding brooding refers to feeding and management of 1-15 days old. The larvae grow rapidly during the brooding period, and the feathers are exchanged and grow rapidly.
1, insulation. The thermoregulatory function of the young chicks is not perfect, and their adaptability to the external environment is poor. At the same time, the young chicks are small, relatively large in surface area, and have more heat dissipation than chickens, so the chicks are very sensitive to temperature. Insulation conditions are more stringent than those for chicks.
The temperature during brooding should be maintained at 35-38°C for the first 2 days, then lowered to 34-35°C, maintained for one week, and then gradually reduced to normal levels. When the temperature inside the brooder is the same as the room temperature, it can be defrosted. Keep indoor temperature at 20-24°C. Temperature control not only depends on the thermometer, but more importantly, it observes the status of the prostitute and sees Shi Wenwen. At the same time, it should also pay attention to weather changes. Winter is slightly higher and summer is slightly lower. Rainy days are slightly higher and sunny days are slightly lower. Nights are slightly higher and days are slightly lower.
2, ventilation and humidity. The purpose of ventilation is to remove harmful gases from the house and exchange fresh air. As long as the temperature in the brooding room can be ensured, the better the circulation of air, the better. In the first stage of brooding (1 week old), relative humidity is maintained at 60% to 65%, and people do not feel dry. Later (2 weeks old) due to increased body temperature, respiratory volume and excretion increased, the brooding room is prone to moisture, so the feces should be removed promptly, relative humidity of 55% to 60% is appropriate.
3, drinking water. After long-distance transportation or staying in the incubator for a prolonged period, the proficient chicks lose a lot of water and should supply warm water in time to restore the spirits to prosper. Otherwise, the chicks will become fragile and affect their health. If water is not supplied for a long time, it will make the prostitute drink water and even wet the feathers, causing coldness and diarrhea. Drink 0.01% potassium permanganate on the first day, drink for 3 days, and drink potassium permanganate once a week. For long-distance transportation, it is advisable to drink 5% glucose solution on the first day.
4, feeding. The growth and development of the chicks are rapid, and the nutrient requirements for the feed are high. If the chicks get out in 24 hours, they will eat for 16 hours. If they get out in 15-18 hours, they are generally required to eat within 24 hours. The starter diet uses mixed feed, which can be used for special spores or chicken feeds for 0-14 days. They usually use day and night to eat freely, and must keep constant water to feed. There are also regular quantitative feedings, in principle, 2 times in the morning and evening. But it depends on the specific circumstances.
5. Feeding density. If the stocking density is too large, the survival rate will be reduced, the young chicks will grow slowly, and the growth will be uneven; if the density is too small, the cost of brooding will be increased and the insulation will be unfavorable. Therefore, stocking density should be properly arranged. The first week of age is about 250-300 square meters per square meter, the second week of age is about 100, and the third week of age is 75-100 (100 egg tarts, 75 meat palate). The winter density can be increased appropriately. It decreases accordingly. At the same time, the density should be appropriately adjusted in combination with the size of the lice.
6, light. Reasonable light during brooding has the effect of promoting growth and development. Insufficient light will delay the time of production. Generally, the first week uses 24 hours of light. After 8-9 days, the lights will not be turned on during the day. Use natural light and turn on the lights at night.
7, accessories. The best material in the brooder is the sack sheet, and coarse cloth sheets can also be used. Because the legs and feet of newly hatched chicks are weak and weak, they can easily cause a leg when walking on smooth accessories, and they cannot stand and become disabled. As a result, excipients are prohibited from newspapers or plastics.
8, daily management. The daily work of brooding should be meticulous, patient, and strengthen health management. Regular observations of the spirits of the prostitutes. Feed materials, change water, clean floors and clean feces on time, and keep them clean. Its daily management includes the following points:
(1) There must be someone who is on duty 24 hours a day. Every morning and evening, you should observe the movements of your deafness, such as whether your mental state is good, whether you are eating or drinking water, if you find a problem, find out the cause, and take immediate action.
(2) The manure dish is cleaned once on the 3rd, and the drinker is cleaned once a day.
(3) Turn on the lights after sunset every day to master the lighting time.
(4) Always check the temperature, humidity, and ventilation in the brooding box. Before going to sleep, be sure to check if the temperature is appropriate.
(5) Observe the feces of the chicks. Normal feces are dry and spiral. Fecal color, thick and thick and feed related. Feeding fishmeal was yellow-brown for a long time, and it was brownish and dilute when feeding green material. It was normal. If feces are found in red and white, they must be checked.
(6) Eliminating poorly grown youngsters in time.
(7) Diseased youngsters are found, isolated in time, and necropsy in time.
(8) At the age of 1 week and 2 weeks, samples were weighed and compared with the standard body weight.
