In summer, high-temperature and high-humidity weather laid a challenge for laying hens. Due to the relative simplicity of hens laying hens, lack of appropriate facilities and equipment to effectively regulate the breeding environment, hens are very sensitive to high temperatures, no sweat glands to their own body temperature Regulation leads to reduced feed intake, low egg production, and low disease resistance. Therefore, it is recommended that farmers should adapt to local conditions and conduct scientific feeding and management to ensure stable production and high yield of laying hens in summer.
Increase ventilation in homes. To increase the ventilation of the house, ceiling fans and fans can be installed to increase the air flow in the house and have a certain effect on the cooling of the house.
Reduce breeding density. The suitable density for breeding is no more than 8 per square meter. If the stocking density in the house is large, the excrement will not be cleared in time, and the chicken will easily develop heat-ejection disease under high-temperature and high-humidity conditions, causing chickens to die.
Carry out renovations. Repair the coops, increase the thickness of the roof or ceiling, prevent radiant heat, can also be used to cool the roof by spraying water.
Increase drinking water. Ensuring adequate water supply allows the layer to drink clean drinking water in a timely manner, increasing the number of water changes and ensuring that the drinking water is cool. The water temperature should be between 10°C and 13°C.
Build a arbor. The stadium should be shaded with nets and shade shelters. It is also possible to plant trees to shade the chickens, or to create shade in the stadium.
Give heat-stress-resistant drugs. Add 200 grams to 300 grams of vitamin C or 200 grams to 800 grams of sodium bicarbonate per metric ton of water in drinking water. Mix the above medicines in the feed to allow the chicken to eat, and also achieve the effect of heat stress resistance.
Pay attention to the disinfection of drinking water equipment. Drinking water equipment is prone to breeding and breeding micro-organisms in the summer, and key management of drinking water equipment must be performed once a day.
Strengthen sewage and drainage. Clean up the drainage channels of the stadium in time to ensure smooth flow. If there are water pits or pits in the playground, the chicken's excrement will be disturbed and it will be susceptible to parasitic diseases and other infectious diseases.
Adjust feed and feeding methods. In summer, the feed intake of chickens has dropped, and chickens have been selected to feed cool chickens in the morning and evening. Energy has to be added to feedstuffs, such as adding corn oil, etc., and increasing the digestible green and blue juicy feed.
Pay attention to the prevention of parasitic diseases. In the summer, parasites are severe and chickens are susceptible to infection. Antiparasitic drugs should be regularly administered for prevention.
