To examine the effects of the salinity level of drinking water on the egg production and quality of Alabio ducks.
A total of 60 female Alabio ducks, aged 6 months, were subjected to this study. All ducks were kept in stage-type cages (1 m length × 1 m width × 0.5 m height), where each cage was inhabited by 4 ducks for 56 days of experimentation. All ducks were offered a mixed ration ad libitum for laying ducks, according to the nutritional requirements for egg-type ducks. The treatment in this study was drinking water with five stratified salinity levels, namely P0 = freshwater (0% salinity); P1 = water with a salinity of 0.75 practical salinity unit (PSU) (equal to 0.75 g NaCl/l); P2 = water with a salinity of 1.5 PSU (1.5 gm/l); P3 = water with a salinity of 2.5 PSU (2.5 gm/l); and P4 = water with a salinity of 3 PSU (3.0 gm/l). Observations were made on water intake, feed intake, egg production, and egg quality (egg weight, egg shape index density, shell proportion, shell thickness, yolk index, albumen index, and Haugh unit).
The results showed that the difference in salinity levels in drinking water from 0.75 PSU to 3 PSU did not affect water intake, feed intake, egg production, or egg quality of Alabio ducks for the first 56 days of the laying period ( > 0.05).
It was concluded that Alabio ducks have a good tolerance for drinking water salinity of up to 3 PSU, or equal to 3 gm/l NaCl.
研究饮用水盐度水平对阿拉比奥鸭产蛋量和蛋品质的影响。
本研究共选用60只6月龄雌性阿拉比奥鸭。所有鸭子饲养在阶梯式笼中（长1米×宽1米×高0.5米），每个笼子饲养4只鸭子，试验期为56天。根据蛋用型鸭的营养需求，为所有鸭子自由提供蛋鸭混合日粮。本研究的处理方式是提供五种分层盐度水平的饮用水，即P0 = 淡水（盐度0%）；P1 = 盐度为0.75实用盐度单位（PSU）的水（相当于0.75克氯化钠/升）；P2 = 盐度为1.5 PSU的水（1.5克/升）；P3 = 盐度为2.5 PSU的水（2.5克/升）；P4 = 盐度为3 PSU的水（3.0克/升）。观察指标包括饮水量、采食量、产蛋量和蛋品质（蛋重、蛋形指数密度、蛋壳比例、蛋壳厚度、蛋黄指数、蛋白指数和哈夫单位）。
结果表明，在产蛋期的前56天，饮用水盐度水平从0.75 PSU到3 PSU的差异对阿拉比奥鸭的饮水量、采食量、产蛋量或蛋品质没有影响（P>0.05）。
得出结论，阿拉比奥鸭对高达3 PSU（相当于3克/升氯化钠）的饮用水盐度具有良好的耐受性。
