摘要:为了探讨不同醒抱方法在处理抱窝鹅中的使用效果,将80只抱窝母鹅随机分为4组(试验Ⅰ、Ⅱ、Ⅲ组和对照组),每组20只。试验Ⅰ组填服氯丙嗪,剂量为每只1片(25 mg)/d;试验Ⅱ组填服溴隐亭,剂量为每只1片(2.5 mg)/d;试验Ⅲ组填服妈富隆(去氧孕烯炔雌醇片),剂量为每只1片/d,(每片含去氧孕烯0.15 mg和炔雌醇0.03 mg),以上3组连续用药3 d,第四组作为对照组,饲养在网床上进行,试验Ⅰ、Ⅱ、Ⅲ组每天光照14 h,对照组光照24 h,试验期为30 d。结果表明,处理后一定时间内3个试验组的醒抱率均显著高于对照组(P<0.01);醒抱处理后一定时间内3个试验组鹅的恢复开产率均显著高于对照组(P<0.01),而试验Ⅰ、Ⅱ组又显著高于试验Ⅲ组(P<0.05)。说明使用药物进行醒抱处理的效果优于传统的物理醒抱方法。

Abstract: In order to observe the effect of different waking-up methods on broody goose, 80 broody geese were randomly allocated to 4 groups. The first group were waken up by taking 1 tablet Chlorpromazine each broody goose everyday(25 mg), the second group were waken up by taking 1 tablet Bromocriptine each broody goose everyday(2.5 mg), the third group were waken up by taking 1 tablet Desogestrel and Ethinylestradio(Desogestrel 0.15 mg, Ethinylestradio 0.03 mg). All treatment groups took medicine 3 days, the fouth group was the control group which fed on the high web-bed and accepted continuous strong lighting. The results showed that the waking-up rate and resume lay rate of all treatment groups were significantly higher than that of control group(P<0.01), and were significantly higher in group I and II (P<0.05). It was indicated that the effect of taking medicine were better than traditional waking-up methods.
Key words: waking-up methods; brooding; goose; waking-up results
我国是世界上地方良种鹅资源最丰富的国家,也是鹅养殖量最多的国家,据有关资料介绍我国鹅的存栏量和鹅肉产量占世界总量的90%左右[1]。对于大多数地方良种鹅来说,鹅的产蛋性能不高,主要原因在于其具有繁殖季节性和较强的抱窝习性[2]。良种选育是减小种鹅抱窝发生率的重要途径,一些地方良种鹅经过选育后已经失去抱性或抱性很弱。但是大多数的种鹅依然保留着较强的抱性,直接影响着其产蛋性能。关于如何解决母鹅抱性问题,不同地方也积累了各自的种鹅醒抱经验。在种鹅规模化生产条件下如何采取有效措施,解决种鹅抱窝问题尚无确定的结论,依然处于探索的阶段[3]。……
