Extract

When feed is offered ad libitum from hopper feeders, with water supply remote from the feeder, the feed conversion ratio with pelleted diets is improved by around 10% compared with non-pelleted diets (Patterson and Walker, 1989). This difference was reduced to around 6% when mono-place feeders with built-in water supply were used (Walker, 1990). The improved digestibility due to pelleting accounts for only 1% unit of these differences and the majority therefore appears to be due to feed wastage. A hopper feeder was developed by Baxter (1989) which minimised feed wastage of both pelleted and non-pelleted diets when assessed by short term collections of spilled feed. It was considered that a longer term growth trial would be a good indicator of the benefits of this feeder compared with other designs which had been used here in previous experiments.
