【摘要】:为寻求猪饮水时浪费水量少的节水饮水器或饮水方式,在舍内温度为20~25℃的条件下,选择60头体质量为20 kg的保育猪进行鸭嘴式饮水器、杯式饮水器和Swing饮水器的用水总量和浪费水量的比较研究。试验结果表明,3种饮水器的用水总量无显著性差异(P0.05)。每头猪浪费水量由小到大依次为:杯式饮水器(1.13 L/d)Swing饮水器(1.42L/d)鸭嘴式饮水器(1.93 L/d),其中,鸭嘴式饮水器浪费水量极显著高于Swing饮水器(P0.01),极显著高于杯式饮水器(P0.01),杯式饮水器和Swing饮水器浪费水量无显著差异(P0.05)。杯式饮水器浪费水量占用水总量百分比(15.17%)Swing饮水器(17.58%)鸭嘴式饮水器(25.10%),杯式饮水器和Swing饮水器浪费水量占用水总量百分比极显著低于鸭嘴式饮水器(P0.01),杯式饮水器和Swing饮水器浪费水量占用水总量百分比无显著差异(P0.05)。与鸭嘴式饮水器对比,杯式饮水器和Swing饮水器起到一定的节水作用。
