The additive can effectively improve the appetite and immunity of the ducks, the growth speed and the slaughtering rate of the ducks are increased, assimilation of all nutrient substances is facilitated, the feed utilization rate and the duck raising economic benefits are improved, meanwhile, the duck meat quality can be improved so that the duck meat can be more nutrient and delicious, and the laying rate of laying ducks is increased.

The invention relates to a laying duck cage-rearing feeding and management method, which comprises the following steps of (1) putting and arranging a duck cage: adopting a stair-shaped overlap-type multilayer cage arrangement mode, setting a duck cage gap at one side facing a feeding groove to be in a circular shape, and arranging a spraying device in the middle above each layer of duck cage; (2) caging; (3) daily feeding and managing: in the first 15 days of an early laying period, starting to gradually reduce the feeding amount, in the first 1 week of the early laying period, reducing the feeding amount to be 20 percent of the daily feeding amount, and continuously feeding until egg laying starts; (4) feeding and managing during an egg laying period; (5) illuminating: in the first 15 days of the early laying period, manually controlling an illuminating system, firstly illuminating for 2 hours, then controlling laying ducks in a dark environment for 6 hours, and crossing in light and shade, wherein at the beginning of the early laying period, the illuminating time of every day is not less than 12h, and at a middle-laying period and a late period of laying, the illuminating time of every day is not less than 16h; (6) controlling the temperature; (7) controlling the humidity.

The invention discloses a laying duck feed and a production method thereof. The feed is characterized by comprising the following raw materials by weight: 30-40 parts of corn flour, 10-15 parts of soybean meal, 5-10 parts of feather meal, 5-10 parts of brewer's grains, 5-10 parts of molasses, 1-3 parts of Indigowoad Leaf, 1-3 parts of Scutellaria baicalensis, 1-3 parts of phellodendron, 1-3 parts of radix bupleuri, 0.5-1.0 part of calcium hydrogen phosphate, 0.1-0.3 part of salt, 0.1-0.3 part of beneficial bacteria, and 0.1-0.3 part of trace elements. The production method consists of: mixing the raw materials evenly, then carrying out drying, sieving and granulation, thus obtaining the laying duck feed. The laying duck feed provided by the invention has the advantages of high efficiency and environmental protection, good palatability and low cost, meets the nutritional needs of the egg laying period of laying ducks, and improves the laying rate of laying ducks.

The invention discloses an intelligent brooding duck cage, which comprises a support and a cage body with more than two tiers, arranged on the support. A control system is arranged outside the cage body, and an automatic lighting system and an automatic spraying disinfection system are arranged on the top of the cage body; a feces conveying system is arranged below the cage body, and a cage door,an automatic water dispensing system, a trough and a ventilation pipeline system are arranged on the side surface of the cage body; the automatic lighting system, the automatic spraying disinfection system, the excrement conveying system, the automatic water dispensing system and the ventilation pipeline system are all connected with the control system and are centrally controlled by the control system. The intelligent brooding duck cage has reasonable structural design, is suitable for whole-course standardized, large-scale, intensive and ecological production in duckling breeding, accords with the policy guidance for developing modern clean animal husbandry, meets the physiological habits of ducklings, can provide scientific breeding of laying ducks, saves the space and the cost, and brings an ecological industrialized breeding technical mode with unique characteristics.
