1. Ventilation. Regardless of the size of the house or the number of chickens, it is very important to keep the air in the house fresh and well ventilated. If the ventilation is not good, there will be a large number of harmful gases such as ammonia, carbon dioxide and hydrogen sulfide released, affecting the normal growth of chickens, laying eggs and causing a variety of diseases. In the production, a floor window can be set at the bottom of the chicken house, a large window can be set in the middle, and an exhaust cylinder can be worn on the roof. In autumn and winter, the central window can be closed, only the floor window and the exhaust cylinder on the roof, and the exhaust fan can also be set in the middle to quickly eliminate the polluted air in the house. In winter, pay close attention to the ventilation system. Do not cause thieves or reduce the temperature of the house temperature too low to reduce feed consumption and prevent various diseases.
2. Light. Illumination has a great influence on the laying performance of chickens. Reasonable light can stimulate ovulation, promote normal growth and development of chickens, and increase egg production. Production should be started from the age of 20 weeks of laying hens, artificially supplemented with light, increase the light for half an hour each week until reaching 16 hours per week, then ensure that the effective light for 16 hours every day, until the chicken is eliminated four weeks before, and then gradually increase the light time to 17 hours until eliminated. Artificial light supplements work best every morning before dawn. When supplementing lighting, install 3-5 watt bulbs per square meter. The lamp is about 2 meters away from the ground. It is best to install a lampshade for the spotlight. The distance between the lamp and the lamp is about 3 meters to ensure uniform lighting throughout the house.
3. Feeding. Eggs are often fed with dry powder and the number of feedings is 1-2 times a day. If feeding once, the timing is better at 3 o'clock in the afternoon; if two feedings are used, feeding should be done at 9 o'clock in the morning and 3 o'clock in the afternoon. The daily feeding amount is generally 100-120 grams per chicken, and the amount of feed is appropriately increased or decreased according to weight changes, so as not to affect the production of eggs. In order to maintain the strong appetite of chickens, it is necessary to ensure that there is a certain empty time every day. First, it can prevent the feed from being stored in the trough for a long time to produce mildew. Second, it can prevent the chickens from producing anorexia and picky eating habits.
4. Drink water. The consequences of water shortage are more serious than those of lack of materials. Water is important for regulating body temperature, nutrient operation, digestion and absorption, and waste elimination. The water content of normal eggs is more than 70%, and each bird needs to drink 230-360 ml of water per day. When drinking water is insufficient, the feed intake of chickens is reduced, and at least a 2% egg production rate can be reduced. Poor water quality can also lead to decreased egg production and egg and egg weight. Therefore, laying hens should be provided in a timely manner to meet the drinking water standards, adequate clean drinking water, try to use a nipple drinker, should be wiped daily, regular disinfection. When drinking water is immunized, water quality should be checked carefully. Chlorine, organic matter and disinfectant should not be included. It is best to add skimmed milk powder.
5. Temperature. The most suitable temperature for chickens is 18°C-23°C. Temperatures that are too high or too low are not conducive to egg production. In the autumn and winter, attention should be paid to keeping the warm work. The doors and windows of the chicken house should be covered with grass curtains at night or in the wind and snow days. It can also use corn stalks and other wind barriers outside the northern wall of the house to keep off the wind; it can also be in the ceiling. On the top, add rice husks, sawdust, etc. as a cold-proof layer.
6. Humidity. The optimum humidity is 60%-70%. The humidity inside the house is too low, the hens are sluggish, the feathers are disordered, the skin is dry, the feathers and claws are dull, and the chicken body is easily dehydrated, causing respiratory diseases in the flock. The thermal conductivity of moist air is 10 times that of dry air. If the humidity in the house is too high in winter, the heat emitted by the chicken body will increase, making the chicken colder. In the production, it is possible to reduce the humidity in the house by means of enhanced ventilation and the placement of quicklime blocks in the room.
It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
[Functions of medical eye masks]
1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.
4. The breathability must be good, generally there are vents
