Mountain forests, orchards, barren slopes and other places are suitable for free-range green shell laying hens. Because of the large space of breeding resources, good environment, fresh air, abundant sunshine, comprehensive nutrition, large amount of chicken activities and relatively long breeding time. Because of less pollution, its meat and egg products are similar to pollution-free natural products, with good quality and delicious taste, which are deeply loved by consumers.
Advantages of 1
Improve product quality and grade, and increase economic benefits. When chickens are raised in the pastoral environment of mountains and forests, they have large activity space, lively feathers, strong muscles, moderate subcutaneous fat, delicious meat and good egg taste, which is suitable for market demand and has strong market competitiveness.
Reduce feed consumption and feed cost. Raising chickens in woodland can reduce feed consumption and feed cost.
Improve the survival rate of chickens. Mountain pastoral environment has fresh air, cool summer, quiet environment, less stress factors and less possibility of introducing diseases, so it is an ideal habitat for free-range chickens. Conducive to the healthy growth of chickens and high reproductive rate of chickens. Because of the large activity space, the density of chicken manure is reduced, which reduces the pollution of raising chickens.
2 feeding conditions
Generally, under good feeding and management conditions, the mortality rate of chickens before 100~ 120 days old should be less than 3%.
The living conditions of green shell laying hens are as follows: ① Keep the temperature and temperature. Temperature is the key to the success of brooding (www.nczfj.com). The suitable temperature for brooding period is 32~35℃ before 7 days old, and then drops by 3℃ every week. After 28 days of age, it can be kept warm, and the indoor temperature should be kept at 25℃. When the temperature is right, the chicks will spread out evenly to rest; If the chicks are tired, wheezing and dry feet, the indoor temperature is too high and the humidity is low; If the chicks are curled up and chirping all the time, it means that the temperature is low and cold air enters, which needs to be checked and handled. Chickens need to be raised in a dry environment, and the appropriate humidity is 60%~70% before 10 day, and 50%~60% after 10 day. ② Ensure ventilation. The purpose of ventilation is to reduce the amount of harmful ammonia and floating dust in the green shell laying hen house, replenish fresh air in time, and adjust the temperature and humidity in the house. Even in the coldest winter, we should ensure daily ventilation. The method should be to raise the indoor temperature first, then open the doors and windows for ventilation for a while, and then close the doors and windows when the indoor temperature drops below the required temperature. Repeated ventilation can achieve the purpose of ventilation. Pay attention to ventilation during the whole feeding process of chickens. ③ Suitable density. 1~30 days old, with about 30 green shell laying hens per square meter on the ground or online; 3 1~60 days old, the ground or online level is about per square meter 15; From 6 1 day to adult chickens, the average number of chickens raised on the ground or online is about per square meter 10. (4) sufficient light. 24-hour illumination is implemented in the first two days, and then 23-hour illumination time is maintained, that is, 1 hour night illumination can be stopped to prevent chickens from being frightened and crushed to death due to power failure. The light intensity should change from strong to weak. The light intensity of 2~3 watts/square meter before 14 days old was changed from 2 1 day old to 0.7~ 1.5 watts/square meter to ensure that green shell laying hens could see the drinking water intake. ⑤ Clean drinking water. The water that chickens drink should be clean and hygienic. Drinking buckets and sinks can be used for flat or free-range drinking water, and attention should be paid to ensuring that chickens only have enough drinking places. ⑥ According to the different growth stages of chickens, feed should be made of whole-grain feed or concentrated feed produced by feed manufacturers with stable quality and good reputation, or pure whole grains such as corn and bran. It is best for chicks to use full-price granular crushed material.
3 inventory management
After 1 month old, chicks can be transferred to a chicken shed for feeding, and electrolytes and multivitamins should be added to drinking water for three days before and after transfer to reduce the stress of transfer. Newly-transferred dehydrated green shell laying hens can't graze immediately, so they should be kept in the shed for 1 week to avoid the phenomenon that chickens don't return to the shed after grazing.
Strengthen feeding management to prevent the invasion of natural enemies and animal injuries. Choose sunny days with warm weather to graze, and graze for 2~4 hours every day for the first few days, and then increase the grazing time month by month; The grazing place can be selected near the henhouse first, and gradually from near to far. In training, chickens can form conditioned reflex by beating buckets and blowing whistles. When it is windy and rainy, stop stocking when the dew is too heavy to prevent the feathers from getting wet and getting cold. Put enough buckets (troughs) and drinking fountains near the shed for chickens to eat freely in the morning and evening. You can only feed 60 ~ 70% full in the morning, which will promote the green shell laying hens to find food independently and increase the number of insects and nutrients that chickens eat. Take the chicken back to the henhouse at night and be sure to feed it well.
The inside and outside of the green shell laying hen house and the activity places of chickens should be disinfected regularly, which can be disinfected with quicklime or disinfectant, and the disinfection frequency should be increased when diseases occur. A batch of chickens should be cleaned and disinfected in time after being transferred out of the henhouse. Chicken farms should be refused to visit as much as possible. Under special circumstances, visitors should be disinfected, disinfection pots should be placed in the entrance and exit passages of chicken houses, and disinfection should be carried out in and out. Kill flies and rats, and use drugs regularly to kill rats. In the process of grazing, feeding managers should be good at observing the mental state of green-shell hens and pick out abnormal chickens in time for isolation treatment.
