High-yielding laying hens take about 72 weeks from hatching to culling, so it is said that laying hens are raised for 500 days. According to the characteristics and laws of the growth and development of laying hens, the feeding of laying hens can be divided into several feeding and management stages. In order to give full play to the high-yield performance of laying hens and obtain the best feeding benefits, in addition to breed factors, the key is to be familiar with and master the requirements of laying hens at different growth stages and the technical points of chicken feeding and management.
The key to the success or failure of raising chickens is brooding. The quality of brooding directly affects the growth and development of chicks, the survival rate, the uniformity of the flock, the disease resistance of adult chickens, the egg production of adult chickens, and the duration of peak egg production. , and even the economic benefits of the entire chicken industry. Therefore, it is very important to do a good job in the chicks feeding and management.
1. Preparation before brooding
Before entering the chicks, there must be enough time planned to do the cleaning, flushing, fumigation and disinfection of the chick house, check the heating and heat preservation equipment, and prepare the feed, commonly used medicines, utensils, etc. The chick house should be thoroughly cleaned, the feed pans, drinker cups and other utensils should be cleaned, and strict disinfection should be carried out. If the chick is raised on the ground level, the bedding should be exposed to the sun for a week before the chickens are entered for natural disinfection. Before entering the chicks, the brooding house should be set on fire and pre-heated in advance, especially in late autumn, winter and early spring. It must be fired 3 days in advance to allow the walls, floors and facilities to be thoroughly heated, so that the temperature in the house will be relatively stable and easy to control.
Temperature is one of the key factors for the success or failure of brooding. Providing a suitable temperature can effectively improve the survival rate of chicks. Due to the imperfect thermoregulatory function of chicks, chicks are very sensitive to temperature. If the temperature is too low, the chicks are easy to swarm, squeeze and die. The cooling rate cannot be too large, and the humidity is too high or too low, which is not conducive to the growth and development of chicks. Therefore, regular farms are professional poultry equipment such as chicken drinking line, which can control the humidity and ventilation equipment of the chicken house to ensure that the air in the chicken house is flowing. The cooling pad ensures that the chicken house will not be too wet, and the professional poultry feeding line ensures that the feed the chickens eat is clean and hygienic. There are also many professional equipment that can make your farm more professional.
3. Drinking water and eating
Drink water before the chicks start eating, and then feed them after 2 to 3 hours. Adding 5% glucose + electrolytic multi-dimensional or quick supplements to drinking water within 1 week of age, prescribing rehydration salts, etc., its functions are mainly health care, anti-stress and conducive to meconium excretion. After 1 week of age, tap water can be drunk. Chicks' demand for water far exceeds that of feed. The constant water and water quality should be kept clean and hygienic. The overnight water should be replaced in time. The use of professional drinker nipple can ensure the cleanliness of drinking water. The chicks generally start eating 24 to 26 hours after hatching. The starter can be millet, crushed corn and other feeds, and gradually change to compound feed after 3 days of age. Feeding times, in the first week of feeding, a small amount should be added frequently to avoid indigestion and waste of feed. It is not advisable to feed too full each time. When feeding, pay attention to changes in feed consumption at any time. Too much or too little feed consumption is a harbinger of illness in chicks.
4. Reasonable lighting system
Light can improve the metabolism of chickens, increase appetite, increase the heme content of red blood cells, and promote the metabolism of calcium and phosphorus in the body. Practice has proved that the length and intensity of light, the color and wavelength of light, the start and end time of light stimulation, and whether the dark period is continuous or indirect, will all have an important impact on the activity, feeding, drinking, physical development and sexual development of chickens.
The chick has a strong metabolism, and the fresh air and exhaled carbon dioxide and water vapor required per unit body weight are large, and the ammonia gas is continuously released from the chicken manure. Unfavorable environmental factors in the house will bring stress to the chickens, affect the normal activities of the chickens, affect the growth and development of the body, reduce the immune function of the body, increase the probability of disease infection in the body, and hinder the growth and development of chickens to varying degrees. Therefore, the brooding room should pay special attention to ventilation. There is a contradiction between ventilation and heat preservation in the brooding room. The effective way to solve this contradiction is: in early spring, late autumn and winter, when the air is cold and there is a lack of ventilation equipment, it can be carried out when the chickens are eating, because the chickens are eating In the active state, when the house temperature drops by 2℃～ 4℃ , it basically does not hinder the chicken body, but it is necessary to avoid facing the wind directly. Wait for the flock to finish feeding, and then close the window when 2/3 of the chickens in the flock are starting or drinking. It is strictly forbidden to open windows to increase ventilation when chickens are resting. Otherwise, chickens are prone to colds or respiratory diseases. Ventilation and insulation are often contradictory issues. To solve this pair of contradictory problems, the best way is to install skylights on the roof, or install ventilation fans in the high windows under the eaves.
