How to Make Eggs Prolific in Late Spring and Early Summer

In late spring and early summer, the temperature gradually warms up, but the sunshine hours are still relatively short, and the contradiction between ventilation and heat preservation still exists. If the rearing and management cannot keep up, the egg production can easily fall. So, how to make laying hens produce more eggs in the late spring and early summer? First, pay attention to cold warm in late spring and early summer, the weather gradually warming, but sometimes the late spring cold chicken farmers often suffer losses, so cold is still the most important issue. The most suitable temperature for chicken egg production is 18 °C ~ 23 °C. The temperature of the chicken house is lower than 5°C, and the egg production is obviously reduced. Below 0°C, production will be stopped. For this reason, the house temperature is preferably kept at 8°C to 13°C. Plastic greenhouses can be used in the north of the country in the spring, but care should be taken to ensure that the plastic film is in contact with the ground and walls at the time of membrane demolition. At the same time, we must pay attention to the timely removal of dust on the surface of the plastic film, knock down the water droplets on the plastic film surface, so that plastic film light transmission is good. On the north side of the house, corn stalks, etc. can be used to set off the wind barrier and prevent the cold. Second, adjust the feed formula should be appropriate to increase the spring heat higher feed, increase the ratio of concentrate and protein content, and use a variety of feed mix to ensure that the feed nutrition is comprehensive, to make all chickens can even feed. At the same time, the calcium content in the feed (3% to 4%) should be increased to supply enough b vitamins, green feed, and sprouted grains. In addition, you should avoid disturbing the flock and minimize stress factors. Third, the supply of adequate drinking water is an indispensable condition for laying hens, the consequences of water shortages are often more serious than the lack of material. If there is insufficient drinking water, feed remuneration will be reduced, resulting in decreased egg production and even dehydration or death. Cold days should insist on drinking warm water in order to maintain the body temperature of the chicken body. The number of drinking water in spring is usually 3 times during the day and 2 times during the night. Fourth, ensure the light time Normal egg laying requires 16 hours of light each day, the spring natural light time still can not meet the needs, should be artificial supplemented. The supplemental light bulb should be within 60 watts, and the light intensity should be 3 to 5 watts per square meter. The light is about 2 meters away from the ground. It is best to use a lampshade to light up and the light is 3 meters away, so that the house will get even light everywhere. Turn on the lights at 5 o'clock each morning, use natural light during the day, turn on the lights at night, turn off the lights around 21:00. Fifth, pay attention to ventilation Ventilation late spring and early summer, the chicken house ammonia, hydrogen sulfide, carbon monoxide, carbon dioxide and other harmful gases are relatively high, ventilation should be carried out in clear weather. In order to reduce the generation of harmful gas in the house, the manure should be removed in time to keep the house dry and clean. If the humidity is high, about 500 grams of superphosphate can be sprinkled on the surface per square meter, which can effectively eliminate the ammonia in the house. The flat-raised chicken house should also pay attention to controlling the rearing density, and no more than 6 breeding animals per square meter. VI. Doing a good job of disinfection and epidemic prevention The end of spring and early summer is the breeding season of various pathogenic bacteria. It is very important to do a good job of disinfection and epidemic prevention. The wall can be painted with 20% lime emulsion, the ground can be sprayed with 2% sodium hydroxide or 0.2%-0.5% peroxy acetic acid solution. The trough and sink can be disinfected with 0.1% benzalkonium bromide solution. The disinfection should generally be selected at higher temperatures. In the afternoon. Feces should be cleaned and transported in a timely manner, and sealed fermentation. At the same time, according to actual needs, such as chicken Newcastle disease, fowl cholera, infectious bronchitis and other vaccination (bacteria) seedlings immunization and insect repellent work. Deworming should be carried out on a regular basis, and a broad-spectrum and highly effective anthelmintic such as insect worms should be used. Each time, every 10 kilograms of body weight is used to repel insects with 0.3 grams of insecticide powder.
