GIANT AFRICAN LAND SNAIL (ARCHACHATINA MARGINATA (SWAISON) - GROWTH PERFORMANCE


FED DIETS SUPPLEMENTED WITH 
MULBERRY (MORUS ALBA
AND SIAM WEED (CHROMOLENA ODORATA)

A RESEARCH PROJECT SUBMITTED TO THE DEPARTMENT OF ANIMAL SCIENCE, FACULTY OF AGRICULTURE AND NATURAL RESOURCES MANAGEMENT
EBONYI STATE UNIVERSITY, ABAKALIKI


IN PARTIAL FULFILMENT OF THE REQUIREMENT FOR THE AWARD OF BACHELOR OF AGRICULTURE (B. AGRIC) IN ANIMAL SCIENCE

ABSTRACT
One hundred and twenty (120) young growing snails of about 8-10 weeks of age were used in an 8 week feeding trial. It was to determine the growth performance of giant African land snail (Archachatina marginata) fed diets supplemented with mulberry (Morus alba) and siam weed (Chromoleana odorata). The experimental diets were 0% mulberry and 0% chromoleana leaves (T1), 5% mulberry leaves and 0% chromoleana leaves (T2), 5% siam weed leaves and 0% mulberry leaves (T3). Result indicated significant (p<0.05) difference in the final body weight between the treatment 3 and other treatments (T1, T2). There were no significant difference (p>0.05) in the initial body weights. Significant differences (p<0.05) were recorded in the weight gain, feed intake and feed conversion ratio among the dietary treatments. In conclusion, the results suggest that inclusion of mulberry leaves and siam weed leaves in the diet of snail will improve their growth performance.
