Breeding techniques of green shell laying hens in rural areas

Green shell laying hens are generally scattered, with strong resistance to rough feeding, disease resistance and foraging ability. in general, many farmers in rural areas raise green shell laying hens in mountainous areas. this feeding model has the characteristics of good isolation conditions, less disease occurrence and high survival rate. low investment and other characteristics. Using this model, farmers can reduce feeding costs, while the quality of green-shell eggs can be guaranteed. At present, the breeding of green-shell laying hens is becoming more and more prosperous in Guizhou.

The first consideration is the construction of chicken sheds. Farmers should take measures according to local conditions, use local materials, and simplify according to bad conditions. Permanent and simple shacks can be built. The width of the shed is 5 meters, the length is determined according to the size of the flock (15 chickens per square meter), and the height in the middle of the shed is 1.8 to 2 meters. The front and rear walls are about 1 meter high, and the roof 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 and heat preservation. The four walls of the shed are made of straw into a fence, or surrounded by plastic sheeting, plastic film, linoleum and so on. There should be drains around the shed. There are several holes that can be closed to the south of the shed for chickens to enter and leave. The plastic sheeting or film around it is active, and in hot weather, it can lift 0.8 to 1.0 meters to cool down.

Secondly, in the feeding of green shell laying hens, full-price ingredients should be fed during the breeding period, and the method of feeding less and more meals should be adopted to ensure that the chicks are always in a state of exuberant appetite so as to promote the growth and development of chicks. During the breeding and stocking period, more green fodder and soil miscellaneous grains should be fed. Green feed is generally recommended for raising chickens, and high-quality forage grass can be used as one of the main feed sources for raising chickens, which greatly reduces the fine feed by 2.32 kilograms and saves 8.5 yuan per chicken. The economic benefit is remarkable. Generally choose to plant high-quality forage grass such as hn-mc excellent chicory, hn-mc superior seed amaranth and so on. Feeding chicken with forage grass can enhance the disease resistance of chickens, improve the survival rate and efficiency of raising chickens, and reduce the use of drugs, especially to completely replace the use of multi-vitamins.

Finally, the management of green-shell laying hens needs strict epidemic prevention and deworming. Farmers should pay attention to the prevention and control of coccidiosis, and it is better to prevent coccidiosis at the age of 15 days and 35 days respectively. You can feed chickens with 300 grams of chopped mixture or fried water with spicy Polygonum, Portulaca oleracea and garlic. Usually in the feed to add appropriate amount of Chinese herbal medicine Radix Isatidis, andrographis paniculata, honeysuckle, wild chrysanthemum, forsythia, etc., try to control the dosage of western medicine and reduce drug residues.
