On August 9th, Taihang Chicken Standardized Eco-farming Technology Training Meeting was held in Shijiazhuang, the capital of Hebei Province. More than 300 experts and professors from the province and abroad and large-scale farmers attended the meeting. At the meeting, Prof. Su Sumin from Hebei Agricultural University, Liu Huag, a researcher at the Hebei Provincial Animal Husbandry and Pedigree Research Unit, and Ni Huiyong, a senior livestock clerk, gave explanations in a simple way from the perspectives of feeding management and disease prevention. In order to meet the needs of readers and farmers, we specially arrange the wonderful explanations of the experts and publish them, hoping to give everyone guidance and help. Teacher Liu Huage, a member of the newspaper's newspaper expert service group, pointed out that since 2000, the ecological cultivation of Chaiji has begun to develop rapidly and large scale. Zhaihuang Natural Company and Wuyuan Liuwang have emerged in our province. The leading enterprises such as Sichuan and Shijiazhuang Luoshanqi have greatly promoted and led the large-scale ecological breeding of chickens in the province. Judging from the current market, the prospect of large-scale breeding of chaiji is still broad. The commercial price of chaiji eggs is as high as 20-25 yuan/kg, which is 2-3 times the price of ordinary eggs. Through more than a decade of development, as people's living standards continue to increase, the demand for firewood eggs and meat will increase. Teacher Liu Huage pointed out: “Ecologically raising farm chickens is suitable for development in mountainous areas, orchards, and underforests. Everyone can rationally arrange production according to their actual conditions.†Put pastures to choose a good environment and high efficiency Teacher Liu Huage said: “Cultivating farm chickens requires a quiet and hygienic environment, and strict selection of venues.†More than 20 kilometers from the town; more than 500 meters from the residential and traffic arteries; 50-100 meters from the general road; from other farms, slaughterhouses more than 1,500 meters; from more than 500 meters away from the surrounding cropland. The slope of the mountain field is below 25%, and the soil is suitable for sandy loam or loam, avoiding the shady slope. There are special roads required for transporting feed, eggs, feces, and supplies, and there are sufficient water and electricity. Grazing land should have food that can be eaten throughout the year. There are green grass, branch buds and insects in spring; there are abundant stems, leaves, flowers and insects in summer; insects and grass seeds, stems and leaves are used in autumn. Major wild foods; winter mainly feed on dead leaves and grass seeds. Artificially planting some artificial pastures or vegetables, such as alfalfa, bitter vegetables, lettuce, cabbage, etc., to artificially plant green plants throughout the year. In addition, we must choose a flatter place to build a chicken house with a perch and an egg cage, and design it according to 10 per square meter. Each building houses 300-500 chickens. The area of ​​the house is 30-50 square meters (5 meters wide and 10 meters long), and the distance between the houses is 100-200 meters. Chai chicken out of the shell training and obedient to good management Teacher Liu Huage pointed out that the first time after the hatching of the chicken was started, the breeder blew the whistle and then fed it. This procedure must be maintained. The broiler house is kept for about 5 days. When the grazing is started, the range should be small and then gradually expanded. If a large-scale grazing is carried out at one time, some chickens go too far and are lost because they do not recognize the way back to the nest. During the first few days of grazing, chickens should be prevented from getting together in the evening, and if they get together, they should be spread apart to avoid death and to prevent coccidiosis. The age of grazing is generally 40-60 days old, and it is determined according to the outside temperature. When the average outside temperature is above 20°C, it can be stocked. In the specific production, Professor Liu introduced: "Farmers should focus on training the upper shelf of chickens and laying eggs." Training on the shelves If you are a plane brooder, you need a shelf at night after the age of 30 days. When some chickens cannot be climbed, you should increase the nighttime lighting. Wait until the chickens are all on the shelves and turn off the lights. Stick to the 3-5 days and the chickens can be automatically put on the shelves. . In general, the habitat of each chicken is 17 cm to 20 cm. If it is a three-dimensional cage brooding, it is necessary to teach the upper body after going to the stocking place. Training eggs One nest box for every 5-6 hens. The size of the nest box is 35cm, 35cm, 35cm in length and width, and the bedding is 2-3cm thick, such as rice hull, wheat bran, wheat straw, etc. At the age of 4 months, complete empty egg shells or table tennis balls are placed inside the nesting box, and 80% of the chickens can be removed after they are opened. For individual chickens that lay eggs everywhere, they must be forced into the nest box before each egg production and released after the eggs are produced. Sticking to 5-7 days can change the habits. Reasonable supplement and light supplement chicken benefit will be strong In order to improve the efficiency of ecological breeding of chickens, teacher Liu Huage pointed out: “Farmers should make reasonable supplements after grazing and return to their nests, depending on the season and the circumstances in which they are grazing, and when the hen reaches 140 days of age, To start supplemental lighting." Appropriate feeding Feeding twice a day, for the first time every day from 10:00 to 11:00 in the morning, the flock begins to grazing in the morning, and gradually returns to the nest after 10:00, depending on the extent of hernia sac. The second time when homing, this time must be full, winter can be appropriate to add some granules, such as corn, wheat, sorghum and so on. Preventing brooding When some chickens are found to have nesting behavior, such as standing hair, howling, and long-term nesting boxes, they should be isolated, placed in a cool room or illuminated with strong light, chasing with roosters, etc. . Pay attention to the gradual elimination of chickens with strong nesting ability, reduce the time for the hens to stay in the nest box, and avoid the chickens staying overnight in the nest box. Put chicken and home Early return in the winter should be late, but feeding before and after grazing should be ensured; in early summer, early evening return, pay attention to the middle of the water and shade. Pay attention to listening to the weather forecast. Before the thunderstorm comes, let the chickens return to their nests. Once they can't return to their nests, the rainstorm will drown the chickens or be drowned by the rain. This part of the loss is a large proportion of the grazing chickens. Environmental control 1. Supplemental lighting: The hens reach 140 days and increase their lighting when they weigh more than 1 kilogram and reach 16 hours/day by 160-170 days. 2. Temperature: The winter chicken house does not freeze. 3. Density: The distance between the houses is 200 meters, 300-500 birds per group, and no more than 80 chickens per acre. 4. Clean up every day. Diligently inspect and prevent broken animals by reducing vets and selling money Teacher Liu pointed out that due to the ecological stocking of chickens, the chickens have a longer open-air time. Therefore, farmers should be aware of the eagles flying in the sky and the weasel in the ground. In addition, the husbandry management has been done well, and the laying rate of the chickens has also come up. At this time, everyone can't take it lightly. We must take effective measures to reduce the number of broken eggs and dirty eggs, so that the qualified rate of products goes up and the production of eggs is good. With the sale of merchandise, everyone's labor achievements can be successfully transformed into real money. Prevent animal damage Frequently people inspected the flock of chickens and found that animal pests quickly scared away sounds; they set up scarecrows, raise dogs, and breed geese. Reduce broken eggs Trick or treat 3-4 times a day in the morning and quail eggs in the afternoon 2 times. Eggs are stored at 1-15°C. Nesting mat soft padding: padding available straw, straw, wheat stubble, sawdust and so on. The thickness is 2-3 cm. For chickens that are not laying eggs in the nest box, touch each morning to see if there are eggs. If there are any, they should be closed in the nest box and released after the eggs are laid. During the egg production season, the breeder should often check on the grazing land to see if there are chickens laying eggs in the wild to prevent freezing or corruption. To prevent scaring and disease, supply sufficient calcium and phosphorus: When the diet lacks calcium and phosphorus, it is easy to cause thin or brittle eggshells, increase broken eggs, and usually pay attention to supplement.
In
a hydroponic system, plants are placed in nutrient-enriched water. Mediums such
as gravels, sand or vermiculite can also be used. Thus plants which are placed
in the water absorb the nutrients very easly. When the nutrients from the water
starts finishing , water is recycled or additional nutrients are added.
