Layer chicken comprehensive management measures
(I) Pre-production period environmental control 1. The optimum temperature for chickens is 13°C～24°C. The temperature should be controlled within this range. 2. The humidity can be maintained at about 60%. 3. Ventilation Maintains good air quality. People do not smell of fecal odor after entering the coop. If necessary, heat insulation may not be considered. 4. Lighting strictly implements the light management requirements during the breeding period. The increase in light should not be too long, otherwise it will induce premature delivery of the flock or rectal prolapse. (b) Daily management 1. At the latest, the cage group should be completed within 16 weeks at the latest. This will help the new hens to become familiar with and adapt to the environment before the start of production. It can also reduce the stress for the pre-production period and lay a good foundation for future nutrition and weight control. The environmental physiological conditions. 2. Select and eliminate chickens that are too small, thin and sick according to the requirements of the species when they enter the cage, and group individuals with little difference in body weight to prepare for future nutrition regulation. 3. Body weight control is mainly for the smaller individual body weight control, continue to feed the feed during the breeding period and stop light, as soon as possible in the shortest time to reach or close to the pre-production weight requirements. 4. To ensure adequate supply of drinking water and feed, it is generally not recommended to limit feeding, while drinking water is recommended to regularly add anti-stress drugs such as vitamin C or multidimensional electrolytes. 5. In the selection of premix, try to use the premix for challenging pre-production of laying hens as much as possible, or replace it with the premix for the peak period of production, but the nutrient values ​​are as high as possible when designing the intensive ingredient formula ( For its nutritional indicators, see the above-mentioned forecast date. In addition, the grain size of the feed diet is between the parent material and the egg production material, and it is generally recommended that the particle size be 1.5 to 2.5 mm. (III) Strengthening Prevention and Control of Diseases 1. Immunization According to the immunization plan, the second vaccination of Newcastle disease infectious bronchitis egg drop syndrome vaccine and attenuated laryngotracheitis attenuated vaccine and the second or third vaccination of fowlpox vaccine should be completed in the due date. Bird flu inactivated vaccines are recommended for a second immunization when the egg production rate reaches about 70%. At this stage, the effect of preterm nutrition on the chicken is less, otherwise the effect is greater. It is also recommended that some antibiotics, such as ampicillin and enrofloxacin, be administered three days before and after the immunization of the vaccine to reduce stress. 2. Rational use of antibiotics Regularly add appropriate antibiotics through drinking water or feed to improve disease resistance, especially before and after egg production. Continuous medication for 3 to 5 days to prevent E. coli, cholera, and salmonellosis. 3. Adhere to strict disinfection. In accordance with the requirements of regular chicken disinfection and external environmental disinfection, maintain good environmental hygiene, increase ventilation as much as possible, and timely removal of feces and garbage.

Freckle, that is, through sunscreen and other ways to remove the spots on the face or body. The formation of spots, mainly internal factors: pressure, endocrine disorders, slow metabolism, the use of the wrong cosmetics, external factors: bad living habits, ultraviolet radiation and other factors caused.
freckles
It's 99% genetic, develops between the ages of 5 and 6, and is fairly common in caucasians with blue hair, but Asians are also common. The age of occurrence is before puberty, and light brown spots with a size of about 1 to 2nm are produced in the parts exposed to sunlight. The size, number and pigment depth increase in summer, and get better in winter.
chloasma
Also known as butterfly spot, liver spot, showing light brown, flake, patch size, clear boundary, irregular shape, not taller than the skin, common in the face, symmetrical in both cheeks, the main reason with endocrine, female hormone disorders.
