1. Keeping the climate warm and cold in the early spring has brought a lot of inconvenience to the chicken production, especially the low temperature impact on laying hens is very obvious. Therefore, under normal circumstances, we can take appropriate increase in breeding density, close the doors and windows, add hanging straw, drinking warm water and stove heating and other ways to keep cold insulation, so that the minimum temperature maintained at 3 °C ~ 5 °C.
2. Ventilation early spring As the temperature is lower, the doors and windows of the chicken house are closed and the ventilation is reduced. However, the harmful gases such as ammonia gas, carbon dioxide and hydrogen sulfide produced by chicken exhaust gas and chicken manure accumulation will accumulate in the chicken house, and it is easy to induce Chicken's respiratory diseases. Therefore, early spring chickens should effectively handle the relationship between ventilation and warmth, timely removal of feces and debris in the chicken house, to ensure clean air in the house. When the weather is good at noon, the windows should be ventilated so that the air in the house is fresh and the oxygen is sufficient to prevent the problem. However, be careful when ventilating. Do not blow cold air directly on the chicken to prevent the chicken from catching a cold.
3. Precipitation in early spring chicken house has low ventilation and water evaporation. In addition, the hot air in the house will come into contact with the cold roof and the wall will condense into a large amount of water droplets, causing excessive moisture in the house, giving bacteria and parasites. Mass reproduction creates conditions. Therefore, early spring must be strengthened management, pay attention to keep the house clean and dry, timely repair of damaged sinks, avoid over-filling with too much water, it is strictly forbidden to splash water on the floor.
4, disinfection and disinfection work should be throughout the entire process of raising chickens. In early spring, the temperature is low, and the frequency of bacterial activity declines. At this time, the weather is still cold and the resistance of chickens is generally weakened. If you ignore the disinfection, it can easily lead to outbreaks of the disease and cause heavy losses. Therefore, we must do a good job of disinfection and regular disinfection.
5. Supplemental lighting is the driving force of all life activities. In early spring, it is still a short night, and laying hens often suffer from a lack of light and cause egg production to decline. In order to overcome this natural defect, artificial supplemental lighting can be used to make up for it. In general, the total time of daylight should not be less than 14 hours, but it should not exceed 17 hours (more than 17 hours will cause chicken physiology disorders). For example, the natural daytime light is 12 hours, and it is necessary to manually supplement the light for 2 hours to 5 hours every day.
6. Energy-enhancing chickens rely on energy feeds that are fed into the body to obtain heat energy to maintain body temperature. The lower the outside temperature, the more heat energy the chickens use to protect the cold. It has been determined that winter and spring chickens consume about 10% more food than other seasons. Therefore, in the early spring chicken feed must ensure adequate energy feed, in addition to ensuring a certain percentage of protein, but also should be appropriately increased high-energy feed containing starch and sugar, in order to meet the chicken's physiology and production needs.
7. The resistance of strong early spring chickens is decreasing. Special attention must be paid to the work of preventing epidemics and preventing diseases, and vaccination should be carried out regularly. According to the actual situation, some preventive drugs can be regularly targeted, and the content of vitamins and trace elements in feeds can be appropriately increased, the constitution of chickens can be enhanced, the ability of chickens to prevent diseases and production capacity can be improved, and the aquaculture efficiency can be improved.
Reflective Vest is high-visibility (HV) clothing, a type of personal protective equipment (PPE), is any clothing worn that has highly reflective properties or a colour that is easily discernible from any background. Yellow waistcoats worn by emergency services are a common example. Occupational wearers of clothing with high-visibility features include railway and highway workers, airport workers, or other places where workers are near moving vehicles or in dark areas. Some cyclists wear high-visibility clothing when riding amongst motor vehicles. Hunters may be required to wear designated high-visibility clothing to prevent accidental shooting.
