The hot weather recently reduced the intake of layer chickens, reduced egg weight, thinned egg shells, and even stopped egg production. In order to ensure stable production and high yield of laying hens, fine tubes must be fed. First, the most suitable temperature for heatstroke cooling layer is 13°C-25°C. For this reason, the sheds and sports grounds should be shaded by a pergola to prevent direct sunlight, doors and windows and air vents should be opened, air circulation should be maintained, and white paint should be applied to the exterior of the house. Adhere to the early morning late closing. Second, adjust the structure of the diet to properly reduce the energy feed in the diet, and increase the protein and mineral-rich feeds such as bean cake, fish meal, aphids, cockroaches, fish and shrimp, cocoon, feed yeast, meat, etc., so that the protein content reaches 18% - 20%, while supplying enough green and juicy feed. Third, careful feeding focused on feeding in the morning and evening cool time, avoiding midday feeding. Mixed feed should be fed along with the mix, not overnight. Add high-quality, fresh and clean green and juicy feed, cut it properly, and do not feed rot, mold, yellowing or forages and feeds with pesticides. Daily fresh and clean drinking water, add a small amount of salt and chili powder to increase the appetite, but the amount should not be too much. Fourth, to prevent stress in the feed added 0.1% fumaric acid or 0.05% vitamin B12 and vitamin C, 50ppm-100ppm bacitracin zinc and 0.15% ammonium chloride; add 0.63% saline in drinking water and 0.2% of baking soda and other resistance Stress substances can inhibit central nervous activity and significantly increase chicken heat stress resistance. In addition, take 30 grams of Daqingye and Sophora flavescens, 20 grams of Rhizoma Imperatae and 20 grams of Toona sinensis, 25 grams each of Atractylodes and Forsythia, 100 grams of plaster, and 100 kg of feed to feed the chicken in the powder, and receive heat and heat. Anti-stress, egg production effect. Fifth, reasonable cut feather chicken surface without sweat glands. The feathers on the chest, abdomen, inner thigh, and wings of laying hens can be shortened to only 1 cm long, which can increase the laying rate by 15%-20%. Sixth, density and light reasonably reduce the breeding density of layer. Generally, ground chickens should be provided with 3 to 4 eggs per square meter. Increase the perch to prevent the chickens from resting in the egg carton. It is better to raise 10 chickens per square meter of cage bottom area. Intermittent illumination at Shewenda above 25°C, ie 10 hours of light (8 hours - 18 hours), 5 hours of darkness (18 hours - 2 hours), 2 hours of light (23 hours - 1 day of the next day), 7 hours of darkness (1 hour - 8 hours), can increase egg production rate of 5% -10%. Seven, scientific calcium supplement laying eggs need about 4 grams of calcium - 4.4 grams of calcium. For this reason, the dietary calcium content of laying hens is preferably 3% to 3.5%. Every day from 12 to 18 o'clock, it is best to feed chickens with high-calcium feed. Generally, the ratio of calcium to phosphorus in feed is 2:1 to 1:1, and the absorption rate is higher. At the same time, it is required to add vitamin D and vitamin C to the feed, which will promote the absorption and utilization of calcium and increase the eggshell hardness and egg production. VIII. Preventing laying hens from "big nests" Adding 5% stir-fed hemp seed to chickens in the feed, or intramuscular injection of testosterone propionate (25 mg each) or feeding painkillers (2 tablets each) Medicines such as isoniazid (1 tablet each) and ephedrine (1 tablet each) have the effect of preventing chickens from "brewing nests". Nine, do a good job of health and epidemic prevention should promptly remove the feces, cleaning the feed tank and sink, every 1 week - 3 weeks, with 3% to Sol solution or 20% lime milk disinfection of the house. Timing on the chicken house walls, egg boxes, habitats, the environment spraying insecticides to prevent mosquitoes and flies bite. There is a sand pit inside the shed, and put a proper amount of sulphur and lime into the pool to let the chicken sand bath to kill the body surface parasites. Frequently add 0.5% potassium permanganate to drinking water. Regular injection of a variety of disease (bacteria) seedlings to prevent the occurrence of infectious diseases, using sulfa-6-methoxy-pyrimidine, chlorpheniramine, an allyl chloride, coccidia net, etc. added feed alternate feeding, prevention and treatment of coccidiosis. X. Clever removal of harmful gases, chickens and other hot excrement can easily ferment, produce many harmful gases, cause respiratory diseases in laying hens, and affect egg production. The following methods can effectively remove harmful gases. One is to use 7 parts of ferrous sulfate powder each week and 3 parts of dry coal ash to mix. Disperse 10% of the weight of the chicken droppings into the chicken house to remove ammonia and hydrogen sulfide from the inside. The second is every ten square meters of litter. 5 kg of sulphur powder is mixed to make the PH value less than 7 to reduce the production of ammonia gas. Third, 350 g of superphosphate is used per 50 chickens. The effective time is 5 days to 7 days. Daqingye, garlic, and the appropriate amount of straw are burned in the chicken house, which can suppress and kill bacteria, and can deodorize once every 10 days.
