在北方,因受冬季寒冷气候和粗放饲养管理方式的影响,蛋鸭冬天处于休产期。目前国内外高产蛋鸭年产蛋量均在20千克以上。据有关部门统计,辽宁省丹东地区现有蛋鸭年产蛋量平均不足7千克,究其原因,除去品种和粗放的饲养方式外。鸭舍的建造是重要因素。现利用的鸭舍(俗称鸭窝),沿用原始构造,冬不保暖,夏不防暑,更无光照,导致蛋鸭自换羽至来年变暖期内产蛋大幅度下降,乃致停产,造成“养鸭一冬,工料白扔”的现象。致使饲养成本加大,经济效益低下。为了挖掘蛋鸭生产潜力,缓解市场供需矛盾,增加经济效益,针对塑膜棚养畜禽已广泛应用于畜牧业,而用于养鸭业仍不够标准、规范的实际,我所自1992年开始,对鸭舍的改造进行了广泛的研究,建造了规范化的暖棚鸭舍,几年来的生产实践和推广,可使蛋鸭四季均衡产蛋。
In the north, because of the cold weather in winter and extensive feeding and management methods, the ducks are in the winter. At present, the annual egg production of high-producing ducks at home and abroad is more than 20 kilograms. According to relevant department statistics, the average egg production per year of ducks in Dandong, Liaoning Province, is less than 7 kilograms per year. The reason for this is to remove the variety and extensive feeding methods. The construction of duck houses is an important factor. The duck houses currently used (commonly known as duck nests) follow the original structure. The winter is not warm, the summer is not sunstroke-proof, and there is no light. This results in a significant decrease in egg production from the feathering to the warming period in the coming year, resulting in the suspension of production. The phenomenon of “drinking ducks for a winter and throwing materials at work”. As a result, the cost of feeding increased and the economic efficiency was low. In order to tap the productive potential of ducks and ducks, alleviate the contradiction between supply and demand in the market, increase economic efficiency, and raise livestock and poultry for plastic membrane sheds has been widely used in animal husbandry, and for the duck industry is still not enough standards, norms of the actual, I have been since 1992 The extensive study of the transformation of the duck houses and the construction of a standardized warm-shed duck house have been implemented in the past few years to ensure balanced production of egg-duck in the four seasons.
