【摘要】 本文研究了绿头野鸭 ( Anas platyrhynchos)和北京鸭杂交亲合过程的行为表现和繁殖行为特点。观察结果表明 ,绿头野鸭 (雄 )和北京鸭 (雌 )配组后的亲合过程 ,经历了如下几个阶段的行为变化。1不接触北京鸭的恋旧行为阶段 ;2与北京鸭融为一群的行为转变 ;3发生亲昵行为和调情行为的阶段 ;4从不成功交配的爬跨行为到成功实现交配的繁殖行为阶段。从配组开始到成功繁殖共经历了 1 30天 ,其中亲合过程到出现交配行为时经历了 30天。从不成功的交配到成功交配产出受精蛋经历了 1 0 0天。观察还表明 ,不能实现成功交配的原因是作为父本的野鸭与作为母本的北京鸭体型大小悬殊 ,阻碍了交配的顺利进行 ;有利于亲合成功交配的生物和非生物因子包括对父本进行采精按摩 ,父本有性经验 ,雌雄间有性的吸引力 ,对水的喜好 ,对食物的依赖、移去原配偶和环境安静等。文中给出若干经验总结和建议更多还原

【Abstract】 This paper dealed with the behaviour of affinity and reproduction in the course of cross breeding between mallard (Anas platyrhynchos) and Beijing duck. The results suggested that the course of affinity after mating up the mallard (2 male) and Beijing duck (4 female) including several stages as follow: ①the stage of the mallarddid not touch to Beijing duck but was miss of the old spouse (the female mallard); ②the stage of merging together of the two kinds of ducks; ③the stage of having affectionate action and flirtatious action between the two kinds of ducks; ④the stage of coupling action but failure at the first and succeed at the end. The observation had been last 130 days, including 30 days from The beginning of mating to the time of having coupling action but failure and 100 days then to the end of succeeding in production the fertilized eggs. The observation suggested that the duck had been failure in mating was due to the difference in the body size between the mallard (too small) and Beijing duck (too big), that was leading to the failure that productive organs of male mallard could not arrive at the productive organs of female Beijing duck. The biological and non biological factors that were aid to the affinity and the succeeding in mating were as follow: The gathering sperm massage to the mallard, the malehaving experence of sexual intercouse, there was sexual fascinafion between male and female, the hobby to water, depending on food, moving off the old spouse (the female mallard) and the silent enviroment et al. Several experence summarys and suggestion had been put up in this paper.更多还原
