ABSTRACT
The experiment was carried out to determine the growth performance of Archachatina marginata fed with different selected natural diets. The objective was to determine weight gain, shell length increment, shell width increment and to determine the best feed for A.marginata. Eighty (80) juvenile snails of average weight of (80± 3.26g) were procured from Edobor snail farm in Benin City, Edo state. They were randomly assigned to five (5) dietary treatment; Dietary1, Dietary2, Dietary3, Dietary 4 and Dietary5 (formulated feed; Control).
The experiment was laid out in a randomized complete block design (RCBD) with five (5) dietary treatment and two block per treatment with each block containing eight juvenile snails. Data collected was subjected to two-way analysis of variance (ANOVA) was further tested with Duncan multiple range test to separate the mean that are significant. The result revealed that snails fed with Diet5 (formulated feed) had the least FCR (feed conversion ratio) which recorded the least value 0.67 while the mixed leaves had higher FCR (1.42) The results showed a significant difference(p<0.05) among the treatment combinations.
The highest weight gain was recorded with Diet5 which also had the highest shell length and shell width. Those fed with Diet1 had the least value. The result of the study showed that higher growth performance for A.marginata was favored by Diet5 (Control feed of about 25% crude protein).
