With the increase in the use of wet feeding systems, there has been a controversy over the optimum water to feed ratio to be used in these systems. Braude et al., (1967) showed that the feed conversion ratio was 20% higher for wet fed pigs compared to dry fed pigs. However, Forbes et al., (1968) found no significant difference in daily gain between wet and dry fed pigs.
Gill et al., (1987) conducted an experiment to investigate the effects of different water to feed ratios on the performance of growing pigs provided with an additional water supply. They showed that liveweight gain and feed conversion significantly improved (p < 0.05) as the water to feed ratio of the liquid feed was increased from 2:1 to 3.5:1.
The objective of this experiment was to investigate whether water to feed ratio effects digestibility, digestible energy and nitrogen retention.
