Impacts of nipple drinker position on water intake, water wastage and drinking duration of pigs

초록

Water determines the life quality of pigs, however, adequate measures need to be taken in order to reduce wastage while the animals are drinking. The current study hypothesized and examined a suitable position at which to fix the nipple drinker to provide sufficient drinking water to pigs while also limiting water wastage. Additionally, this study describes both the drinking pattern and drinking duration of pigs. The height to place the drinker was calculated based on the neck movement of the pigs (neck movement angle, NMA). According to the NMA, 3 independent treatments were investigated with angles placed at clockwise 30 degrees, 0 degrees, and counter clockwise 30 degrees. These positions will be correspondingly referred to as T1, T2, and T3, respectively. To understand the diurnal drinking pattern and drinking duration, along with each pig's drinking cycle, the number of visits to the drinker was recorded with a camera. The outcome shows that T3 had less water wastage and a higher average daily gain compared to T1 and T2. Further, the number of visits to the drinker and drinking duration were affected by the treatments. The research affirmed that the nipple drinker with a counter clockwise 30 degrees angle at a proper height is the best at reducing water wastage for finishing pigs. Correspondingly, the T3 treatment might create opportunities to drink more water in group housed
