Summer laying chickens

The hot summer weather coincides with the peak of egg production in the flock. Because the air in the house is damp and dirty, various pathogenic microorganisms are prone to growth and reproduction, causing respiratory tract and intestinal infectious diseases, thus increasing the incidence of chickens, reducing feed intake, and drinking water. Increased, faeces become thinner, and egg weight becomes smaller, eggshells become thinner, broken eggs increase, egg production decreases, and the production of laying hens is lost. To keep laying hens productive, attention should be paid to the following points: 1. The optimum ambient temperature for heatstroke cooling layer is 13°C～20°C. If the temperature is higher than 29°C, the egg production drops by 10%～20%; 37.8°C At the time, chickens are at risk of heat stroke. Therefore, cooling the heatstroke is the key to maintaining high yields. The specific measures are: (1) Cooling: Set up shade nets on the sunny side of the house to avoid direct sunlight. In the case of poor natural ventilation conditions, cool water can be sprayed directly into the house to cool the grass around the house. Reduce heat of reflection. (2) Timely removal of manure: Chicken manure is easily fermented to produce heat, and it emits harmful gases. Clean the house every morning and evening and keep the house clean and dry. (3) Ventilation and ventilation: Open the windows completely, and install fans in the houses to increase air convection and ensure cool interiors. (4) Reduced density: High feeding density is not conducive to heat dissipation of chicken body. Generally, it is advisable to feed 7 eggs per square meter. Second, adjust the diet of hen due to high temperatures, resulting in reduced feed intake, so we must reasonably adjust the diet to better meet the nutritional needs of chicken in the various stages of egg production, sooner or later should be fed more protein, lower energy The rations were fed with green and blue juicy feed at noon, and diversified into feed varieties. In addition, increase the mineral content of feed, especially calcium. The feed should be fed less frequently; the manger should be kept clean so as not to affect the appetite of the chicken or cause gastrointestinal problems. Third, to ensure drinking water The average chicken's drinking water is an average of 150 to 250 milliliters each, and the water temperature is preferably about 10 degrees Celsius. To ensure constant water throughout the day and keep drinking water clean. At the same time, salt can be added to the drinking water to maintain the body's demand for inorganic salts. If the egg is cut off for 24 hours, the egg production will be reduced by 30% and it takes 25 to 30 days to recover if the water is cut off. More than 30 hours, the layer will be moulted. If more feces are found, limit your drinking water. Fourth, strengthen the epidemic prevention Summer is suitable for a variety of pathogenic microorganisms and parasites breeding, coupled with high-temperature stress, resulting in the body's resistance to disease weakened, is a chicken common disease multiple seasons. Therefore, we must do a good job of preventing epidemics, and timely carry out vaccine injections such as chicken Newcastle disease, cholera and chicken gizzards. We must also regularly sterilize chicken coops and cut off the route of transmission of pathogens. Every 7 to 10 days disinfection with anti-toxic alkali, Lysol, etc. once during the onset of disinfection once a day. To regularly add appropriate antibiotics in the feed, such as oxytetracycline, ciprofloxacin, norfloxacin, can enhance the body's resistance to disease.
