Mountain forests, orchards, barren slopes and other places are suitable for raising green shell laying hens. Due to the large space for breeding resources, the environment is good, the air is fresh, the light shines, the nutrition is comprehensive, the chicken activity is large, and the breeding time is relatively long. Due to less pollution, its meat and egg products are similar to pollution-free natural products, with good quality and delicious taste, and are deeply loved by consumers.
advantage
Improve product quality and grade, increase economic efficiency. The chickens are stocked in the rural pastoral environment. Chickens have large living space, lively feathers, bright luster, strong muscles, moderate subcutaneous fat, delicious meat taste, and good egg flavor. They are suitable for market demand and have a strong market competitiveness.
Reduce feed consumption and reduce feed costs. Using woodland chickens can reduce the amount of feed and reduce the cost of feeding.
Improve the survival rate of chickens. The pastoral environment of the mountains and forests is fresh, cool in summer, quiet in environment, less in stress, and less likely to be introduced into the environment. It is an ideal habitat for scattered chickens. It is conducive to the healthy growth of chickens, so that the breeding rate of chickens is high. Because of the large space for movement, the chicken's dropping density is reduced, reducing the pollution of chickens.
Feeding conditions
Normally, the mortality of chickens should be less than 3% from 100 days to 120 days under good husbandry and management.
The living conditions of the green shell layer are: maintaining the temperature and temperature. Temperature is the key to success or failure of brooding. The suitable temperature for brooding period is 32°C-35°C before 7th day of age, then it drops 3°C per week afterwards. After 28 days of age, it can be bred and raised. The indoor temperature should be maintained at 25°C. At the right temperature, the chicks spread evenly to rest; if the chicken is tired, wheezing, and the feet are dry, it means that the temperature in the room is too high and the humidity is low; if the chicks huddled together and keep ringing, the temperature is low, and the cold wind enters. , need to check processing. It is necessary to keep the chicks in a dry environment. The appropriate humidity is 60%-70% before 10 days and 50%-60% after 10 days. Ensure ventilation. The purpose of ventilation is to reduce the amount of harmful ammonia and floating dust in the housing of green shell laying hens, to supplement fresh air in time, and to adjust the temperature and humidity inside the house. Even in the coldest winter season, it is necessary to ensure ventilation and ventilation every day. The method used should be to increase the temperature in the house first, then open the doors and windows for a moment, and close the doors and windows when the temperature in the house falls below the required temperature. Repeated ventilation for several times can achieve the purpose of ventilation. Ventilation should be noted during the whole feeding process of the chicken. Suitable density. From 1 day to 30 days old, the green shell layer chickens are raised on the ground or on the net at about 30 eggs per square meter; 31 days old and 60 days old, about 15 eggs per square meter; 61 days old chickens per square meter 10 or so. There is plenty of light. Two hours prior to the start of the bred, 24-hour lighting was applied. After 23 hours of illumination, the lighting could be stopped for one hour at night to prevent the chickens from being beaten to death due to power outages. The light intensity should be weaker than strong. Before 14 days of age, the light volume of 2W-3W/m2 was changed from the age of 21 days to 0.7-1.5W/m2 to ensure that the green shell layer can feed water. Drinking water is clean. The water supplied to the flock requires cleanliness. Drinking water in a drinking bucket and a sink can be used for raising fish in a flat or free-range. Care must be taken to ensure that the chicken has only enough drinking water. The feed should be based on the chicken's different growth period choose full-grain pellet feeds or concentrates produced by quality stable, reputable feed manufacturers to formulate feeds, or feed with corn, bran and other pure grains. Chicks are best used with full-price pellets.
Restocking management
After the chicks have been defrosted for one month, they can be transferred to stocking chicken sheds for feeding. Electrolytes and vitamins should be added to the drinking water three days before and after the transfer to reduce the generation of transfer stress. The newly warmed shell laying hens that have been transferred to the rearing sheds are not allowed to grazing immediately. They should be kept in the sheds for a period of one week to avoid raising the chicken sheds.
Strengthen feeding management to prevent natural enemies and animal damage. The grazing is selected on a sunny day in warm weather. In the first few days, grazing is conducted for 2 hours to 4 hours each day, and the grazing time is increased month by month; grazing sites may be initially selected around the chicken shed and gradually progress from near to far. During training, chickens can be conditioned by tapping drums and whistle. Rain and rain, when the dew is too large, stocking is stopped to prevent wet feathers and cold. Place a sufficient number of buckets (slots) and drinking fountains near the shed, and allow chickens to eat freely in the morning and evening. In the morning, only 60% to 70% can be fed to promote green shell layer chickens to find food on their own, so that chickens can feed more insects and nutrients. Bring the chickens back to the henhouse at night and be sure to feed them.
The inside and outside of the green shell laying shed and the flock of chickens should be regularly sterilized. Lime or disinfectant can be used for disinfecting. When the disease occurs, the number of sterilizations should be increased. After a batch of chickens are transferred out of the chicken house, disinfection should be conducted in a timely manner. The chicken farm should try to decline to visit as much as possible. Visitors in special circumstances should be sterilized. Disinfection pots should be placed on the entrance and exit passages of the chicken sheds, and they should be sterilized. Flies and rodents are killed and regularly used to eradicate rats. During the process of grazing, the husbandry and management personnel must be good at observing the mental state of the green shell chickens and find that the abnormal chickens should pick out the isolation and treatment in time.
