Key technologies for rural green shell laying chickens. The green shell laying hens are generally free-range breeding, with resistance to rough feeding, disease resistance and foraging ability. Many farmers in the rural areas are using the mountain to raise green shell hens. This feeding mode has good isolation conditions. There are few diseases, high survival rate, and low investment. Using this model, farmers can reduce the cost of feeding, and the quality of green shell eggs produced at the same time is also guaranteed. At present, the breeding of green shell laying hens in the region is growing.
For the cultivation of green shell layer chickens, the first consideration is the construction of the chicken house. Farmers should adapt to local conditions and draw materials locally. Can build a permanent, simple type of shelter. The shed is 5 meters wide and the length is determined by the size of the flock (15 hens per square metre). The height of the shed is 1.8 to 2 meters. Before and after the wall is about 1 meter high, the roof of the shed is covered with a layer of linoleum, covered with a layer of thatch or wheat straw, and covered with a layer of plastic film for waterproof insulation. The four walls of the shed are fenced with straw or covered with plastic sheeting, plastic film, linoleum, etc. There should be a drainage ditch around the shed. There are several holes that can be closed in the south of the shed for chickens to enter and exit. Around the plastic sheet or film is active, in hot days, it can lift 0.8 ~ 1.0 meters, in order to facilitate cooling.
Second, in the feeding of green shell laying hens, the brooding period should be fed with full-priced ingredients, and the method of feeding fewer meals should be adopted to ensure that the chicks are always in a state of strong appetite to promote the growth and development of the chicks. During the grazing and grazing period, more feeds such as green fodder and earth and grains are fed. The green fodder is generally cultivated with artificial grass and raises chickens. High-quality forage grass can be used as one of the main feed sources for chickens, and 2.32 kg of concentrate feed is greatly reduced. The chicken cost savings of 8.5 yuan, significant economic benefits. Generally, high-quality forage grasses such as hn-mc oriole and hn-mc superior seed pods are commonly used. Feeding chickens for pasture improves the disease resistance of chickens, improves the survival rate and breeding efficiency of chickens, and reduces the use of drugs, especially completely. Replaces the use of multiple vitamins.
Finally, the management of green shell laying hens also requires strict prevention and deworming. Farmers pay attention to the prevention and treatment of coccidiosis, and it is generally best to prevent it once every 15 days and 35 days. The coccidiosis can be fed with chicken, purslane, and garlic, each with 300 grams of chopped spices or fried water. Usually in the feed to add the right amount of Chinese herbal medicine Banlangen, Andrographis, honeysuckle, wild chrysanthemum, Forsythia, etc., try to control the amount of Western medicine and reduce drug residues.
