In order to raise ducks and ducks in the house, it is a method of raising from 6 to 8 eggs per square meter (from 100 days to the elimination) in duck or duck sheds. The benefits are large-scale farming, high labor efficiency, high egg production rate, and good economic returns.
Variety of choice
In order to select the local excellent breeder ducks, it is advisable to choose breeds that are narrow, light and strong, mature early, consume less material, have more eggs, and have strong adaptability.
Shed preparation
Usually a laborer can house 500 to 1000 animals, and the construction of the shed should be adapted to this amount. The duck houses should be built on a high ground, with a flat ground and near the riverside or a large pond, facing south to the south, with a height of 6 meters and a height of 2 meters. The size of the shed is determined by the density of 6 to 8 per square meter. . A 120-square-meter to 150-square-meter sports ground was built in front of the duck house, and the terrain was tilted toward the water side so that the duck house, sports ground, and water area were closely connected.
Feeding management
Ducks must be kept in line with the same number of ducks and their ages should be the same, so that the production of eggs is uniform and consistent, and a normal egg production curve can be formed, which can result in a better ratio of eggs and materials and economic benefits.
In addition, the requirements for feed nutrition and production conditions are different in different stages of growth and production of laying ducks. For example, the demand for calcium during egg production is two to three times that before egg production, and the conversion rate of ducks that have produced one year of eggs is 10% to 15% lower than that of new ducks. Therefore, ducks in a duck shed are best all-in and all-out, which is beneficial to unified ingredients, management, epidemic prevention, elimination, technical support and economic benefits.
It is easy to prematurely prematurely produce eggs and duck prematurely if it is opened, and too late will affect economic income. The opening time should be controlled around 150 days. The practice is to control the quality of 100-day to 120-day-old feed and allow it to eat half of the compound feed and half of the green feed to support the large intestine. After 120 days of age, it gradually increases in quantity and improves quality.
Note that the ingredient duck and duck feed is mainly grain (generally 50%~60%), appropriate with cakes (10%~20%), fishmeal or soybean meal (10%~15%), shell powder (1%) and Salt, multivitamins and additives are fed together. The amount of fishmeal is increased or decreased according to the egg production rate. If fishmeal is missing, cocoons, cockroaches, small fish, shrimps, snails, etc. can be used instead. Feed 4 to 5 times a day, each duck fed a daily dose of 125 grams to 150 grams, can be fed twice a day on the peripartum.
The more eroticism the duck induces, the more eggs are laid and the duck population must be equipped with a certain number of ducks. A small herd was reared with 1 male duck for every 100 female ducks; a large herd was raised and 1 male was raised per 200 ducks. The ratio of female to male ducks for eggs is 20:1 to 30:1. The male ducks are isolated during the production period and the moulting period to avoid harassment.
During light production, turn on the light for 3 hours to 4 hours during the night and turn on the light for 1 hour before dawn. The total day and night light should be 14 hours to 16 hours (using natural light during the day) to promote duck gonad activity.
The paddy duck house is floored with rice hulls, straw, or wood chips as litter. The padding is added once a day (the duck dung is covered), and the pad is thicker. The duck house should be ventilated and ventilated to keep it cool and keep it clean and dry.
To prevent falling ducklings from appearing as signs of "falling eggs", we must promptly prevent: First, improve the quality of feed; Second, increase the amount of ducks exercise; Third, increase artificial lighting; Fourth, do duck house insulation. Liquid cod liver oil can be fed conditionally, and each duck is fed with 1 ml of spices every day for 3 days.
Artificially motivated moulting must first stop the lighting at night, do not shovel not shovel, not out of circle, do not swim, feed twice a day, the third and fourth days only supply clean water and green material, cut off material for two days, and then Only feed green and bran and coarse rations for a week and perform forced moulting. In this way, the ducks are neat and their time is short.
Disease prevention and treatment
The new duck shed is sterilized with 20% lime water. If infectious disease occurs, use 20% caustic soda solution for disinfection. Ducks were injected with duck plague vaccine before the shed (80 days to 100 days old) to prevent the occurrence of duck plague (the vaccine should also be injected).
