Strategies to improve water intake can be in the form of drinker
selection and management. It is important to ensure that the drinker
is at the correct height, shoulder height of the smallest pig. In
addition, there should be a minimum number of drinkers to pigs of
10:1 although pens should never have just one water source. As a
result, two drinkers per 10 pigs should be the minimum. Additional
water sources can be added post-weaning and turkey drinkers are
a common addition. (最后一句)
In addition, drinker type can impact water intake and more
importantly in water wastage. A recent study (Torrez et al. 2008)
showed that drinker type did affect water consumption and also
water wastage. Of three drinker types the nipple and push/bowl
drinker improved water consumption although the nipple drinker
showed high levels of wastage (approximately 50%) compared to
the push bowl drinker (about 20%) in this particular trial. (最后一句) |
