Abstract

The feeding trial assessed the performance, carcass and sensory evaluation of adult snails fed solely on leaves of Stylosanthes guianensis or Lablab purpureus as substitute for pawpaw leaf. Ninety-six (96) adult snails were used for the trial, and they were shared into three groups. Each group was replicated four times with 8 snails per replicate in a completely randomized design. Parameters measured include weight gain, feed intake and feed conversion ratio, while dressing percent were calculated. The sensory evaluation was also carried out. The results show that snails fed S. guianensisperformed better in terms of weight gain and feed intake and compared competitively with snail fed pawpaw leaf (P>0.05). The dressing percent, shell thickness, length and width, taste and general acceptability were not affected by the dietary treatments. Snail farmers are encouraged to cultivate S. guianensis to feed snails which can be used to substitute pawpaw leaf.

Key words: Feed conversion ratio, Lablab purpureus, Stylosanthes guianensis, weight gain.
