The green shell layer chicken is superior to the ordinary poultry. Its blood and flesh are rich in nutrients. It is a high-protein, low-fat high-grade nourishing health care product and has a high therapeutic effect. As the breeding of green shell laying hens is a new industry, there are still relatively unfamiliar aspects in breeding, now combined with the author's many years of practical experience, the knowledge and main points of green shell laying hens are introduced as follows: I. Preparation before feeding 1. Poultry house. To seal the doors and windows, spread the cement floor (also can be laid square red brick floor), easy to sterilize, so that after the flooding is easy to dry, moisture-proof hygiene. The wall surface requires a good insulation effect for disinfection. The use of building materials requires economical and practical use without gaps. Use red brick walls and house them with a dry sand powder. The door is covered with a layer of film, and other curtains are used to make curtains to ensure airtightness and security. The form of the roof can be diversified. It must be thoroughly overhauled to prevent leakage of wind and rain. 2, disinfection. Do a good job in the disinfection of the environment inside and outside the poultry house, establish a specific prevention system, and periodically clean up and disinfect all utensils (including feed tanks and sinks) inside and outside the poultry house. The brooding sink and feeding trough must be cleaned and disinfected once a day. The poultry house should be ventilated and ventilated on time to keep the indoor air fresh, the light and temperature should be appropriate, and the feeding and management should be strengthened. The health status of the flock should be observed regularly and the disease prevention and vaccination should be done well. Second, do a good job of brooding insulation work Chicks on the strict temperature requirements, the body villi thin and short, poor insulation and cold performance, young birds feeding less, resulting in insufficient energy supply, so must be outside the amount of heat insulation. But not necessarily the higher the better, the principle of grasping the temperature is high and steady at the beginning, and gradually declines later. It is worth noting that the temperature of the insulation should be different according to the season, day and night, and the size of the chick. It is not scientific to rigidly specify a temperature, and it is easy to cause mistakes. The caregiver's attention should not be focused on the thermometer, but ignore the actual insulation criteria. In the incubation process to do "see chicken Shi Wen." Whether the provided temperature is suitable or not, observe the dynamics, sounds, food intake, and mental status of the green shell layers. The specific performance is: (1) The temperature is suitable: The green shell layer chickens are evenly distributed, lively, feathery, soft and cheerful, vie for food, and are quiet when sleeping. (2) The temperature is too low: The green shell layer chickens gather around the heat source or in a corner to play with piles, plumes and fluffy hair, and emit a sharp cry of a "cockroach, cockroach, cockroach". A long time can easily cause white clams and slow growth. Even squeezed to death. (3) The temperature is too high: the green shell layer chicken is far away from heat, mouth breathing, wings spread, drinking frequently, most of the feathers soaked, there will be some serious casualties. Therefore, we must observe and explore more often and do every step. Third, a reasonable density Density is the key to the success of breeding chicks, should be based on chick species, age, brooding season, feeding methods, feeding, drinking water settings and ventilation and other conditions. The density is too large, resulting in overcrowding and unfavorable feeding. The entire chicken population is unevenly developed and the survival rate is not high. Density is too small, although beneficial to the survival rate and chick development, but not conducive to insulation. Fourth, carefully feeding 1, early drinking. About one-third of chicks have the ability to feed within 24 hours of hatching. When you drink at the beginning, you can add 3%-5% glucose and 0.1% vitamin C and complex vitamin B to the water and drink for 3-5 days. This has obvious effects on alleviating the chicks' transport stress and promoting the absorption of the yolk. Adding an appropriate amount of antibiotics, such as norfloxacin, in the water can also clear the intestines, prevent respiratory tract and intestinal infections, and increase the survival rate of brooding. After 1-2 hours of drinking, if you have 2/3 green shell chickens feeding on the ground, you can eat. 2, open food. The starter should generally use soft boiled rice or sesame soaked in boiled water, and can also use high quality chicken ingredients. Feed the chicks on plastic sheets or newspapers for free feeding. It is advisable to eat about 50% to 80% of chicks. After 3 days, they were switched to feeders or trays. When feeding, 100 chicks were used with 1 tray. After 2 weeks of age, they were increased to 100 chicks with 3 trays. Note that as the age increases, the position of the chute and the drinker is increased accordingly. V. Do a good job in disease prevention and control work Epidemic disease prevention work plan to consider the epidemiology of local diseases, according to the incidence of various diseases and the level of maternal antibodies of green shell layer chickens. Prevention of immunization is an important means of preventing infectious diseases. It is necessary to formulate immunization prevention procedures in accordance with specific local conditions. Do a good job of sanitation and disinfection work, timely cleaning of pollutants in the house, maintaining the health of the poultry house, and reducing the health of the bacteria. The flame disinfection can be carried out on time if conditional. Rational use of drug prevention and control, prevention of infectious diseases such as Marek's disease, salmonella, infectious bronchitis, and tinea corporis.
