1. Reasonable lighting system
Light can increase the metabolism of the chicken, increase the appetite, increase the hemoglobin content of the red blood cells, convert the T-dehydrocholesterol into the vitamin D3 in the skin of the chicken, and promote the metabolism of calcium and phosphorus in the body. Practice has proved that the length and intensity of illumination, the color and wavelength of illumination, the start and stop time of light stimulation, and whether the dark period is continuous or indirect will have an important impact on chicken activity, feeding, drinking water, physical development and sexual development. Generally, the first week uses 24 hours of light throughout the day, and the second week is 19 hours of light. Starting from the third week, the closed chicken battery cages can be illuminated for 8 hours a day. When the light intensity is applied, every 15 square meters of the house will be hung with a 40-watt light bulb at a height of 2 meters above the ground in the first week, and a 25-watt light bulb will be used in the second week.
2. Ventilation
Chicks have strong metabolism, and the amount of fresh air and exhaled carbon dioxide and water vapor required by the unit weight are high, and ammonia gas is continuously released from the chicken manure. Poor environmental factors will bring stress to the chickens, affect the normal activities of the chickens, affect the growth and development of the body, reduce the body's immune function, increase the chance of infection of the body, and hinder the growth and development of the chickens. Therefore, the brooding room should pay special attention to ventilation and ventilation. Ventilation and ventilation of the brooding room is a contradiction. The effective way to solve this contradiction is: early spring, late autumn and winter, when the air is cold and there is no ventilation equipment, it can be carried out while the chicken is eating, because the chickens are eating Material, in the active state, when the temperature is lowered by 2 ° C ~ 4 ° C, the chicken body is basically no hindrance, but to avoid direct wind blowing. Wait for the flock to finish eating, and when 2/3 of the chickens in the flock start or are drinking, close the window. It is strictly forbidden to open the window when the chicken is resting to increase ventilation. Otherwise, the chicken is prone to catch a cold, or thus induces a respiratory illness. Ventilation and insulation are often a contradiction to a contradiction. To solve this contradiction problem, the best way is to install a skylight on the roof or install a ventilation fan in the high window under the eaves.
3.Reasonable adjustment of stocking density
Feeding density directly affects the growth and development of chicks, especially the uniformity of chicks, the density is too large, the range of chicken activity is small, the chickens are squeezed, the feeding is uneven, the chicks are not neatly developed, the size is different; the density is too small, It causes waste of chicken houses and equipment, does not keep warm, and has low economic efficiency. It is generally appropriate to raise about 20 chicks of 1 to 7 days old per square meter. Later, as the age increases, the number of breeding is gradually reduced. When adjusting, the weak chicks should be kept separately, so that they can gradually keep up with the large group level.
