High layers of the feeding and management technology

When the expected rate of increase in egg production when fed 1 week earlier to a high protein diet, when egg production began to decline, the protein content of the diet should be postponed for a week and then decreased. (3) minerals, vitamins, trace elements. Should increase the minerals, vitamins, trace elements, if the chicken or the egg-laying rate of more than 95% of the peak of long duration, multi-vitamin should be times of supply, particularly in summer, the absolute amount of each daily supply should be higher than the other season. (4) calcium. In the diet of laying hens are generally higher calcium content of hair one by one over 52 (Animal Husbandry Bureau of Anyang City, Henan Province, Anyang, Henan 455000, China) at 3%, peak egg production (egg production rate of over 80%) said food in the calcium content can be increased to 3.5% 4%. However, if late in the egg or the summer, calcium should be increased. 2, the number of hens in egg production to increase the peak feeding period of vigorous metabolism of nutrients necessary to maintain the chicken body's own metabolism, but also to meet production requirements, and you should increase the feeding times to ensure adequate volume of feed meet the egg production and physiological needs. Timely immunization and rational drug use 3 egg into the egg period, immunization should be avoided and insecticide to prevent the impact of egg production. When the chickens are sick or appear to be threatened by a disease agent, they should be particularly careful. If the drugs used properly, will artificially cause irreversible drop in egg production and affect economic efficiency. Some drugs on the egg-laying chickens are to be banned, such as sulfonamides and sulfonamide synergist, aminophylline, furans, testosterone propionate, chlortetracycline. Create a favorable environment for the three conditions of a temperature optimum temperature of layers is 13 ~ 23 ~ C, maintained at 10 �� in winter than in summer to keep under 30 ��, not conducive to laying low too. Note sheds summer ventilation, ventilation fans to increase power, change the horizontal to vertical ventilation air, with water sprinklers, due to lower stocking densities to reduce the Sherwin. Johnson stove in winter, through heating heat, but to prevent gas poisoning and smoke pollution. 2 layers of appropriate humidity Humidity 60% ~ 70%. Humidity is too low, chicken feathers disorders, dry skin, and can easily cause dehydration and lead to a variety of Chicken respiratory diseases; humidity is too high, they will make the chicken body contamination, bacteria multiply, easily lead to many diseases, so that egg laying decline. Therefore,[link widoczny dla zalogowanych], the production increase can be discounted with spray and humidity, reduce dust pollution; through increased ventilation or dehumidification sheds put lime to absorb moisture. 3 chicken house ventilation air, oxygen, hydrogen sulfide,[link widoczny dla zalogowanych], sulfur dioxide and other harmful gas accumulation can be induced by a variety of diseases, a direct impact on egg production. Laying hen house ventilation system should be installed to provide fresh air, the air flow, emit carbon dioxide, ammonia, moisture, dust and microbial emissions and pollutants, the chicken house to maintain a comfortable environment. Winter air velocity 0.1-0.2 m / s; summer air velocity 2 m / sec. 4 light illumination principle laying period extended not only shortened. Extended light duration should be based on 18 or 20 weeks of age, the chicken flocks tested motor weight. If the chicken body weight up to standard,[link widoczny dla zalogowanych], 18 or 20 weeks from the extension of light from 1 hour per week, to 14 ~ 16 hours until constant. Otherwise, additional exposure time should be delayed 1 week later. Light intensity is 3 W / m, 40-watt light bulb, lamp 2 meters high, the light from 3 to 3.5 meters. Regularly with a dry soft cloth to clean the lamp, the lamp should be replaced damaged. Should strictly abide by the lights, turn off the lights of time, can not suddenly long, suddenly short. If you often change the exposure time will result in the laying hen cycle disorder, stop or even cause some hens moult. Water in the production of layer 5 is very important, the consequences of water scarcity are often more serious than the lack of material, shortage of drinking water can drop in egg production 2%. 6 chicken house and the stress to maintain a quiet environment, keeping personnel should wear regular clothing, not into the chicken coop Xianzarenyuan; block sheds rat holes, regular elimination in the rat baits cast outside homes; prohibited discharge around the chicken coop fireworks; feed processing, loading and unloading should stay away from sheds to prevent noise stress. Improve health and epidemic prevention work in the four-laying period, the chicken body metabolic intensity, intake of nutrients used for egg production, the resistance is weak, the body susceptible to diseases of chicken, so do a good job laying hens prior to vaccination, drive insect work, laying particular attention to the prevention of intestinal period, the incidence of respiratory disease, according to the actual situation on a regular or occasional preventive administration,[link widoczny dla zalogowanych], found that chickens and timely isolation and treatment. Meanwhile, to improve environmental health, adhere to the daily disinfection of chicken with 1 week 1 environmental disinfection, the timely removal of weeds around sheds, to prevent outsiders from entering rats, mice and chicken coop, so into the pathogenic microorganisms. Observe the health status of chickens, regular clinical Newcastle disease antibody test, abnormal, to identify causes and take timely measures. Mouth
