The winter-warm plastic greenhouses were originally used to grow vegetables. Some farmers in our county explored market trends and converted them to salty rearing broiler chickens in seasons with better chicken prices. They changed them back to planting off-season vegetables in seasons when the vegetable prices were better. To make full use of it and highlight the advantages of short, flat, fast and non-destructive cultivation of broiler chickens, accumulation of fermented chicken manure and litter for vegetable production, and low environmental pollution, creating a better economy benefit. The standard for reconstruction and reconstruction of winter-winter plastic sheds is that the reconstructed sheds can not only meet the needs of broiler production for ventilation, heat preservation, and humidity control, but also facilitate the daily removal of feces, epidemic prevention, feed, and water supply during broiler production. Production management work. 1. According to the east-west direction of the greenhouse, the south face of the slope will be replaced by the horizontally placed cement board in the north wall. The empty part shall be used for ventilation, and the remaining cement board shall be used as spare. 2. The slope foot membrane is properly lifted for ventilation and the standard is set to meet the moisture and ventilation of chickens in different stages of the greenhouse. 3. Along the north-south direction of the steel structure, the bamboo rafts are connected northwards so that they are basically flush with the north wall. The top is covered with plastic film and straw curtains. A part of the north side of the straw curtain must be hung down, and the ventilation openings should be properly blocked to protect the wind and blow the chicken body. In the reconstructed greenhouses, weeds and rain-proof membranes are to be laid on the sheds during the summer to form a shaded shelter so that we can prevent it from cooling and prevent rain. In other seasons, the grass curtains and rainproof membranes are not to be dismantled. However, in winter and spring, we must prevent the straw curtains from becoming rotten after entering the rainwater. When there are winds, the rainproof membranes and straw curtains are prevented from being blown by the wind, and the birds in the shed are alerted. The film can be used to fix the rain film. Preparation before brooding 1. First level the ground and compact it. Ground level raising can be directly paved, and at the foot of the shed to prevent chicken escape. On-line breeding will require pillar nets. The height of the net should be taken into account when removing the excrement, which is generally 1 meter to 1.3 meters and a width of 2 meters to 3 meters. The two rows of grids continue vertically and remain in the middle as walkways. 2. Check the installation of lighting and heating equipment, put the thermometer and hygrometer and correct it. Wash and disinfect all chicken utensils, dry them and put them in the greenhouse. 3. disinfection. Formalin is often fumigated with potassium permanganate, calculated in units of 15ml of formalin + 7.5g of potassium permanganate per cubic meter, and 1 - 2 units can be used in the initial culture shed. It is necessary to use 2 - 3 units, fumigation should be sealed vents, and maintain a certain humidity, difficult to disinfect the parts to be sprayed with lime water or other disinfectant water, and resolutely do not leave corners. 4. Prepare common medicines, vaccines and feeds. The main task of the brooding management brooding stage is to increase the survival and weight gain of the chicks. Using a plastic film, a small area in the shed is separated horizontally from the shelf for brooding. Based on the size of the chicks, the brooding area is gradually enlarged longitudinally. 24 hours before hatching, the temperature and humidity in the shed were adjusted so that the temperature in the broiler area reached 35°C and the humidity reached 65%--70%. The initial raising of greenhouses should be warmed up 48 hours in advance and the ground steam inside the shed should be excluded. 1. temperature. Chickens in different growth stages have different temperature requirements, but like other environmental chickens, they are basically 1 day old - 3 days old 35°C, 1 week old 35°C - 32°C, 1 week old - 2 weeks old 32°C--29°C, 2 weeks old - 3 weeks old 29°C - 27°C, 3 weeks old - 4 weeks old 27°C - 24°C, 4 weeks later 21°C - 18°C. It is worth noting that the decrease in temperature is a slow process, and its adjustment is based on the comfort of chickens. The temperature in the shed should be basically stable every day. There should be a large temperature difference between day and night in early spring and winter. To warm the general use of the ground furnace, which must be prepared before the hatching, coal stoves can also be used to warm, but to prevent gas poisoning. 2. illumination. After 48 hours of continuous light, the intensity is about 25 watts per 10 square meters of light, followed by 23 hours of light, 21 days of age, gradually changed to 16 hours of light, 8 hours of dark, according to different seasons and time Turn on the lights in the evening and turn off the lights the next morning. The installation of the light bulbs can be along the shed, one lamp holder every 5 meters to 8 meters, and the bulbs of different power and color can be installed according to production requirements. 3. Drinking water, feeding. Unless the need for immunity, generally should continue to water, chickens into the young, first give warm water, add 5% brown sugar and electrolytic multidimensional. After drinking water for 2 hours - 4 hours, broiler health ingredients are sprinkled on the tray. In the first week, it is fed 6 times a day. It is advisable to eat basically every 25 minutes to 30 minutes. In the second week, feed troughs or drums were used, feeding 5 times - 4 times a day. After the third week, they were fed 3 times a day to ensure that the material buckets were continuously fed but had less material. Because of the reason of feeding for chickens, the feed is often thrown out of the barrel of the chicken, resulting in greater feed waste. A better way is to choose a larger opening tray and put the bucket into the opening tray so that the chicken can drop the feed from the bucket into the tray. It is worth noting that the drinking fountains should be used every morning and evening. Wash once, the drums should be kept clean, and gradually change the chicken feed at different times. 4. ventilation. Ventilation can meet the oxygen demand of broilers and the discharge of harmful gases, but the premise of ventilation is ventilation, and at the same time, it is necessary to prevent thieves from invading and blowing the chicken body. In summer, high temperature and ventilation are particularly important. It is possible to expand the opening of straw sheds and sheds in sheds and shelves. For a chicken coma caused by high temperatures, the intake may be reduced by using a baking soda solution or cooling with cool water. 5. humidity. The humidity in the greenhouse should not be too large. It is better to use 65% to 70% of the 0-day to 21-day-age, and change to 60%--65% later. 6. Environmental health. It is best to prevent outsiders from visiting inside the shed, especially other farmers and feedstuffs, veterinary drug salesmen and chicken dealers. Timely removal of feces, keeping the chicken utensils clean and the breeder's own hygiene, in order to help reduce the number of chicken disinfection, so as to reduce stress. It is best for keeper to change shoes and change clothes when entering or exiting the greenhouse. Can be isolated in a corner of the shed, isolated feeding for diseased chickens, dead chicken sealed with a plastic bag out of the greenhouse, fixed-point anatomical diagnosis and away from the shed to destroy. 7. Vaccination. The vaccination program and time should be based on the specific circumstances of each place. The following is for reference only. At 7 days old, Newcastle Disease II or IV seedlings were inoculated (one drop of each eye drop). 14 days of inoculation of attenuated virus vaccine (drinking water) of infectious Bursa. 28 days of vaccination with Newcastle disease II or IV seedlings (drinking water). Vaccination is a stress on chickens. Therefore, during the epidemic, the brooding temperature should be appropriately increased, and anti-stress drugs or multidimensional drugs should be added to drinking water for two days before and after vaccination. The vaccine dilution water is preferably cold boiled water, in which an appropriate amount of skim milk powder is added to prolong the effective period of the vaccine. Drink water for 2 to 4 hours before the immunization, and increase the number of drinking fountains to ensure that the chicks can drink water and drink water within 2 hours - 3 hours. Eye drops vaccinated to achieve vaccine absorption really effective. 8. Make a good record of production. Do a detailed record of the above items, and keep abreast of the problems in feeding and management so that appropriate measures can be taken to minimize losses. (1) Production records: variety, source, quantity, date of arrival, stocking density, source and type of feed, room temperature, humidity, etc. (2) Feeding Diary: daily feed consumption, drinking amount, number and cause of death, vaccination status (vaccine type, dose, inoculation method, response), disease occurrence, and abnormalities in the flock. (3) Appearance records: date of sale, date of sale, total number, total live weight, average weight, total feed consumption. Calculate the survival rate, feed conversion ratio, and production expenditure based on the recorded data. Finally, calculate the production cost and analyze the profit and loss situation.

Improving Vision Extract
Lutein and zeaxanthin are widely known to improving vision. They are naturally occurring carotenoids in vegetables and fruits, and have a high concentration of distribution in the macular region. Lutein and zeaxanthin can absorb harmful blue light, reduce its damage to the retina, and thus play a role in protecting vision. They are like a "protective shield" for the eyes, protecting our eyes from the outside environment. In addition, these two serums also have antioxidant functions, which can remove free radicals in the eye and delay the aging of the eye.
Anthocyanins are also an important class of vision improvement essences. Commonly found in plants such as blueberries and black goji berries. Anthocyanins can promote the regeneration of rhodopsin in retinal cells, enhance eye blood circulation, and improve visual acuity. They bring rich color and vitality to the eyes, allowing us to perceive the world more clearly. At the same time, anthocyanins also have anti-inflammatory effects, helping to relieve eye fatigue and inflammation.
DHA (docosahexaenoic acid) in fish oil is also one of the important essens to improve vision. DHA is an important part of the retina, which can improve the signal transmission of the retina and improve the speed of visual response. DHA supplements help maintain the normal function of the retina and prevent vision loss. EPA (eicosapentaenoic acid) in fish oil also has a certain eye protection effect, which works synergistically with DHA to provide comprehensive protection for eye health.
Ginkgo biloba extract is also a part of the vision improvement serum. It can improve the blood circulation in the eyes, increase the oxygen and nutrient supply to the eyes, thereby reducing eye fatigue and blurred vision. Ginkgo biloba extract also has antioxidant and neuroprotective effects that help maintain the normal function of eye nerves.
In addition to the above major vision improvement essences, there are a number of other substances that are also emerging in the field of vision improvement. For example, tea polyphenols can remove free radicals from the eye and protect retinal cells; Zinc is essential for maintaining the normal physiological function of the eye. Vitamin A is essential for vision.
These vision improvement essences work through different mechanisms, working together to protect our vision health. However, it is important to note that vision improvement serum is not a substitute for a healthy lifestyle and good eye habits. Maintaining reasonable eye time, proper rest, a balanced diet and adequate outdoor activities are all important factors in maintaining visual health.
