Practice has proved that the night management of the female duck directly affects its egg production rate. For the mother ducks to produce more eggs and produce bigger eggs, the night ducks' night management must be emphasized. The quiet and safe production of laying ducks is very sensitive, timid, and frightened. In case of sudden fright, the egg production will rapidly drop by 10% to 20%, and some even produce shell eggs and soft shell eggs for three to four days in a row. Therefore, the place where the laying ducks are bred should be avoided as far as possible to avoid the noisy place. The duck house should be built with walls no lower than 1.5 meters high to prevent surprises caused by nocturnal animal raids. In addition, we must pay attention not to breed new and old ducks together, because the new ducks love to call and cause the old ducks to rest badly and affect the laying of eggs. Artificially supplemented with light illumination can not only increase the metabolism of ducks, increase appetite, but also promote the secretion of follicle stimulating hormone and ovulation hormone of female ducks, accelerate the development of follicles and ovulation, thereby increasing the egg production rate. The optimal light for each day and night of laying ducks is about 16 hours. In the absence of natural light, artificial lighting must be added at night. Light bulbs should be installed at 4 to 5 watts per square metre of duck shed. Light bulbs should be installed 2 meters away from the ground. Turn on and off the lights at regular intervals every morning and evening. The time for supplemental lighting should be constant. Do not change the length of time. The proper night feeding of ducks has a powerful metabolic function. When you sleep in the middle of the night, you feel hungry and have night feeding. To this end, every night in the case of maintaining adequate drinking water, it must also be properly fed with nutrient-rich foods, guaranteeing that ducks are not hungry and hungry for the night, which is conducive to egg production. The physiological needs of laying ducks and ducks are closely related to laying. In order to ensure that female ducks often have a strong desire for libido, male and female ducks should be separated overnight in the evening and they should not be forced in the drylands at night. Because the male ducks press on the back of their mother ducks, they often cause work injuries and broken eggs. Over time, the female ducks The libido is suppressed. If the male and female ducks are separated at night, when the water is released for clearing the next day, the female ducks will be eager for courtship and will be eager to go into the water to chase and make gestures to tease the male ducks for mating. In water, the male duck climbs on the back of the female duck. Because of the buoyancy of the water, it will not harm the female duck, so that the female duck will feel comfortable and thus increase the production rate. Duck beds are clean and dry ducks are water birds, but afraid of dampness. Keep the duck house clean, dry and fresh. Every night before the ducks enter the house, the excrement must be removed and the clean, dry grass be replaced. In case of cooling, we must also thicken the mats in time. In addition, the ducks have the habit of laying eggs in grass nests. In addition to the entire site, the thicker and soft mat grasses are laid on the four corners of the duck houses to facilitate egg production.
