This study was conducted to evaluate the water disappearance of nursery pigs (from weaning to 6 wk post-weaning; 6.4 ± 1.07 to 22.0 ± 3.39 kg live body weight) using a randomized complete block design to compare two Drinker Type treatments: Nipple vs. Cup. A total of 336 pigs housed in 16 pens with 21 pigs per pen in 2 rooms (8 pens per room) were used. Pens had fully-slatted concrete floors; floor space was 0.32 m/pig and there was one feeder and one drinker per pen. Pigs were fed corn-soybean-based diets formulated to meet or exceed nutrient requirements. Pigs and feeders were weighed at the start and end of the study. Water disappearance was measured using a water-flow meter fitted to the water pipeline supplying the drinker in each pen. For the overall study period, Drinker Type did not affect ( > 0.05) growth performance; however, average daily water disappearance was greater ( < 0.05) for Nipple than Cup drinkers (2.74 and 2.25 liters/d, respectively; SEM = 0.139). Water to feed disappearance ratio was greater ( < 0.05) for the Nipple than the Cup treatment (5.23 vs. 4.22 liters:kg, respectively; SEM = 0.263). These results suggest that water disappearance from nipple drinkers was greater than for cup drinkers. The lack of an effect of Drinker Type treatment on pig growth performance suggests that the treatment difference for water disappearance was most likely due to greater water wastage for the nipple drinkers rather than any effect on water intake per se.
本研究采用随机完全区组设计，比较两种饮水器类型（乳头式饮水器与杯式饮水器）对断奶仔猪（从断奶至断奶后6周；活体重从6.4±1.07千克至22.0±3.39千克）水分消失情况的影响。总共使用了336头猪，饲养在16个栏中，每栏21头猪，分置于2个房间（每个房间8个栏）。栏舍地面为全漏缝混凝土板；每头猪占地面积0.32平方米，每个栏舍有一个饲槽和一个饮水器。给猪饲喂以玉米 - 大豆为基础的日粮，其配方满足或超过营养需求。在研究开始和结束时对猪和饲槽进行称重。使用安装在每个栏舍饮水器供水管道上的水流计测量水分消失量。在整个研究期间，饮水器类型对生长性能没有影响（P>0.05）；然而，乳头式饮水器的平均每日水分消失量高于杯式饮水器（P<0.05）（分别为2.74升/天和2.25升/天；标准误=0.139）。乳头式饮水器的水料消失比高于杯式饮水器（P<0.05）（分别为5.23升:千克和4.22升:千克；标准误=0.263）。这些结果表明，乳头式饮水器的水分消失量大于杯式饮水器。饮水器类型处理对猪生长性能缺乏影响表明，水分消失的处理差异很可能是由于乳头式饮水器的水浪费更多，而不是对水摄入量本身有任何影响。
