Is it easy to raise green shell laying hens?

Industry insiders predict that green shell laying hens will be difficult to meet the market demand in the next decade, and the breeding scene is very attractive, which is the first choice for breeding enthusiasts and laid-off workers. So how to raise green shell laying hens? Show me the advantages of green shell laying hens first.

What are the advantages of green shell laying hens? Early maturity and prolonged production cycle

Green shell laying hens are small, compact, agile, symmetrical, early in sexual maturity and high in egg production. Adult cocks weigh 3.2-4.5 kg, hens weigh 1.9-3. 1 kg, and lay eggs 160- 180 a year.

The ratio of laying period to laying period is 1:2 (laying period is 5.5 months, laying period is I 1.5 months), while that of green shell layer is 1:3 (laying period is 4.5 months, laying period is 12.5 months), so the effective production cycle is prolonged.

Green shell laying hens have the characteristics of light weight and high feed reward.

The production performance of brown-shell laying hens and white-shell laying hens, whether imported or cultivated in China, has reached the peak at present, and the total weight of 500-day-old eggs is 18-20 kg. However, because hens are heavier, have more nutrients to grow and maintain, and the feed reward is not ideal, each egg 1 kg needs 2.3-2.4 kg of complete feed. The initial laying weight of green-shell layers is1.0-1.5 kg, and the final laying weight is only 1.2- 1.5 kg, and the material consumption of each egg is1.9-2.

High aviation pathogenicity

Green-shell laying hens are rare local breeds in China. Even the mated hybrid breeds contain the blood of local chickens, which are used to being wild and have strong disease resistance. The survival rate is as high as 98%-99% in the breeding period (0- 18 weeks) and over 95% in the laying period (19-72 weeks), which is much higher than that of modern high-yield hybrid laying hens (75%-80%). Except for normal epidemic prevention, little or no drugs are used in the whole growth and production cycle. The eliminated chicken and egg products meet the standards of green food.

Green shell eggs are highly nutritious.

Green shell eggs are especially rich in lecithin, cephalin and neurophospholipid, which play an important role in human nerve development, and also contain a lot of choline substances, which help to increase memory. The contents of ash, calcium and phosphorus in green-shell eggs are higher than those in ordinary eggs, but the water content is lower, indicating that the trace elements in green-shell eggs are much higher than those in other varieties. At the same time, the fresh-keeping period of green-shell eggs is long, with the shelf life of 1.5 months above 20℃, 3 months below 20℃ and 6 months in cold storage. Green shell eggs can be supplied in both off-season and peak season, and do not need special preservation.

What are the advantages of green shell laying hens? In addition, green shell laying hens have the effects of nourishing liver and kidney, nourishing qi and blood, regulating menstruation and stopping leukorrhagia, and the curative effect is excellent and magical, so they are known as? Medicine chicken? .

The breeding technology of rural green shell laying hens is generally free-range, resistant to coarse feeding, disease resistance and strong foraging ability. Generally speaking, many farmers in rural areas use mountains to raise green-shell laying hens, which has the characteristics of good isolation conditions, few diseases, high survival rate and low investment. By adopting this model, farmers can reduce the feeding cost, and at the same time, the quality of green shell eggs produced is also guaranteed. At present, the breeding of green shell laying hens in Guizhou is increasingly prosperous.

The first consideration is the construction of chicken coops. Farmers should adjust measures to local conditions, use local materials and simplify the complex. Can build a permanent simple shed. The width of the shed is 5m, and the length depends on the size of the chickens (per square meter 15). The middle height of the shed is1.8 ~ 2m. The front and rear walls are about 1 m high. The roof of the shed is paved with a layer of linoleum, covered with thatch or wheat straw, and covered with a layer of plastic film for waterproof and thermal insulation. The four walls of the shed are woven with straw into fence walls, or surrounded by plastic sheets, plastic films and linoleum. There should be a drain around the shed. There are several closeable holes in the south of the shed for chickens to go in and out. The surrounding plastic sheets or films are mobile, which can be lifted by 0.8~ 1.0 meters in hot weather to help cool down.

Secondly, in the aspect of feeding green shell hens, we should feed full-price ingredients during the brooding period and adopt the method of feeding less and more meals to ensure that chicks are always in a state of strong appetite to promote their growth and development. During breeding and grazing, we should feed more green feed and coarse grains. Generally, green forage is planted artificially to raise chickens, and high-quality forage can be used as one of the main feed sources for raising chickens, which greatly reduces the concentrate by 2.32kg, saves the cost of each chicken and has remarkable economic benefits. General high-quality grasses such as hn-mc Youyou Chicory and hn-mc Youyou Grain Amaranth. It is selected to feed chickens, which is conducive to enhancing the disease resistance of chickens, improving the survival rate and breeding efficiency of chickens, reducing the use of drugs, especially completely replacing the use of multivitamins.

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. Generally, it is better to prevent coccidiosis once at the age of 15 and once at the age of 35. Chop 300 grams of Polygonum hydropiper, 300 grams of purslane and 300 grams of garlic and feed them to chickens for coccidiosis. Usually, appropriate amount of Chinese herbal medicines such as Radix Isatidis, Herba Andrographis, Flos Lonicerae, Flos Chrysanthemi Indici, Fructus Forsythiae, etc. Add it to feed, try to control the dosage of western medicine and reduce drug residue.

The value of green shell layer embodies the value of chicken. Green shell laying hens have all the characteristics of black-bone chicken, and contain a lot of melanin with extremely high nourishing and health care value, as well as 17 kinds of amino acids, vitamins, selenium, iron and other anticancer elements. The meat is black and firm, delicious and excellent in taste. The amino acids in chicken are significantly higher than those in other chicken breeds. It has the functions of nourishing liver and kidney, nourishing qi and blood, regulating menstruation and stopping leukorrhagia, and its curative effect is excellent and magical, so it is called "medicinal chicken". Moreover, in some areas, the elderly say that green shell eggs have the effect of preventing and treating headaches. The appraisal committee headed by Wu Changxin, an academician of China Academy of Sciences, unanimously recognized that this chicken has extremely high nutritional and health care value, and the research level of this chicken has reached the leading level of similar research in China.

Modern science believes that black food is rich in nutrition and reasonable in structure, and is rich in edible crude fiber, unsaturated fatty acids, vitamins and trace elements. Nowadays, black food is listed as the fourth generation natural functional food after green food (the third generation food), which has formed a strong consumption trend in the international market. Black food will become the most popular natural healthy food for human beings in the 2 1 century.

The value of folded eggs The average weight of green shell eggs is 46 grams. Their eggs are green, the yolk is big and orange, the egg white is thick, and the protein is thick and tender, which is easy to be digested and absorbed by the human body. They contain a lot of lecithin, vitamins A, B and E, and trace elements such as iodine, zinc and selenium. The amino acid content is 7- 10 times higher than that of ordinary eggs, and the yolk is 8 times larger than that of grass chicken. Clinical trials in the Affiliated Hospital of Shanghai Second Medical University and functional tests in Hubei Provincial Health Department and Jiangxi Provincial Hospital of Traditional Chinese Medicine have proved that it has obvious effects on anorexia, pica, low immunity, short stature, cardiovascular and cerebrovascular diseases, thyroid tumors and anti-aging caused by zinc deficiency syndrome in children, and has effects on preventing hypertension, hyperlipidemia, coronary heart disease, cancer prevention, fetal dysplasia, endocrine regulation, delaying female menopause, beauty beauty and supplementing nutrition for pregnant women and patients. Analysis and tests show that green shell eggs can also activate brain cells and enhance memory. Green-shelled eggs are veritable healthy eggs, intellectual eggs, beauty eggs and life eggs, which Yu Ruomu, a famous nutritionist in China, called "magic eggs". As the saying goes, "an egg with a green shell every day keeps the body healthy and keeps the disease away". Green-shelled eggs were accepted as invention patents by the State Patent Office on August 1996.
